Investment Loan Strategies: Variable, Fixed, and Offset Account Features to Look For
Investment loans can amplify your wealth-building strategy—or become a financial burden if structured poorly. The difference comes down to choosing the right loan type and understanding which features actually matter for your investment goals.
Finding the best investment loans means looking beyond just interest rates. Variable versus fixed rates, offset account capabilities, tax deductibility, and flexibility features all impact your long-term returns. For Ontario investors navigating Canadian lending regulations and tax laws, these decisions become even more critical.
This guide breaks down everything you need to know about investment loans—from basic loan types to advanced strategies that maximize tax benefits and minimize risk. Whether you're borrowing to invest in stocks, rental properties, or other assets, you'll learn how to structure loans that work for your situation.
Key Takeaways
Investment loan interest is tax-deductible when borrowing for income-producing purposes
Variable rates offer lower initial costs but carry interest rate risk
Fixed rates provide payment certainty but cost more upfront
Offset accounts can significantly reduce interest costs while maintaining flexibility
Interest-only loans maximize cash flow for investors building portfolios
Loan features matter more than just getting the lowest advertised rate
Overview
Investment loans let you borrow money to purchase income-producing assets like stocks, bonds, rental properties, or business investments. Unlike mortgages for personal residences, investment loan interest is typically tax-deductible, making them powerful wealth-building tools.
This guide covers the best investment loans available to Ontario investors, including variable versus fixed rate comparisons, offset and redraw account features, interest-only versus principal-and-interest structures, and tax optimization strategies.
You'll learn how to evaluate loan features, calculate true borrowing costs, avoid common mistakes, and structure loans that align with your investment timeline and risk tolerance. We'll explore real scenarios showing when each loan type makes sense and how to maximize tax benefits under Canadian tax law.
At Athena Financial Inc., we help Ontario investors understand how investment loans integrate with comprehensive financial strategies, including insurance protection and retirement planning.
What Are Investment Loans?
Investment loans are borrowing arrangements specifically designed to purchase income-producing assets. The key requirement: you must use borrowed funds to generate investment income.
How Investment Loans Work
You borrow money from a lender using investment assets or other collateral as security. The loan proceeds purchase stocks, bonds, mutual funds, rental properties, or business investments. Investment income—dividends, interest, rent, or capital gains—helps service the loan.
Common investment loan types:
Margin Loans: Borrow against existing investment portfolios
Investment Property Mortgages: Finance rental real estate
Lines of Credit: Flexible borrowing for various investments
Term Loans: Fixed-term borrowing for specific investment purposes
The biggest advantage? Interest paid on investment loans is tax-deductible when borrowing for income-producing purposes. This reduces your effective borrowing cost significantly compared to personal loans.
Loan-to-Value Ratios
Lenders typically advance 50-80% of investment asset values depending on investment type. Conservative investments like GICs might qualify for 90% LTV, while stocks might only support 50-70%. Rental properties often qualify for 80% LTV with sufficient down payment.
Risk Considerations
Investment loans amplify both gains and losses. Markets rise 20%? Your leveraged return could be 30-40%. Markets drop 20%? Your losses magnify similarly. Understanding leverage risk is critical before borrowing to invest.
Variable vs. Fixed Rate Investment Loans
Choosing between variable and fixed rates represents one of the most important decisions when selecting the best investment loans.
Variable Rate Loans
Variable rates fluctuate with prime rate changes set by the Bank of Canada. When prime rises, your rate and payments increase. When prime drops, you pay less. Variable rates typically start 0.5-1.5% lower than comparable fixed rates.
Variable rate advantages:
Lower initial rates mean reduced borrowing costs
Benefit from rate drops automatically without refinancing
Smaller penalties if you need to break the loan early
Better for short-term borrowing (under 5 years)
Ontario investors who borrowed on variable rates in 2020-2021 at prime + 0.5% (around 2.5-2.95%) benefited from rock-bottom rates. However, as the Bank of Canada raised rates through 2022-2023, those same borrowers saw payments increase substantially.
Fixed Rate Loans
Fixed rates remain constant for the term—typically 1, 3, 5, or 10 years. Your payment never changes regardless of what happens to market rates. Fixed rates cost more initially but provide complete payment certainty.
Fixed rate advantages:
Payment predictability makes budgeting easier
Protection from rate increases during volatile periods
Peace of mind knowing exact costs throughout the term
Better for long-term borrowing when rates are favorable
The 2022-2023 rate environment showed fixed rate benefits clearly. Borrowers locked in at 3-4% avoided the pain of variable rates climbing to 6-7%.
Making the Choice
Historical data shows variable rates cost less over time in about 70% of scenarios. However, the 30% of times fixed rates win can be financially devastating if you're over-leveraged. Your risk tolerance, investment timeline, and ability to handle payment increases determine which makes sense.
According to Bank of Canada research, understanding rate cycles helps inform this decision, though predicting future rates remains impossible.
Interest-Only vs. Principal-and-Interest Loans
The structure of your repayment significantly impacts cash flow and investment returns.
Interest-Only Loans
Pay only interest charges monthly, with the full principal due at loan maturity or renewal. This minimizes monthly payments, freeing cash for additional investments or living expenses.
Interest-only benefits:
Maximum cash flow for portfolio building
Higher tax deductions (more interest paid means more deductions)
Flexibility to accelerate payments when you choose
Leverage maintenance keeps full investment exposure
Many sophisticated Ontario investors use interest-only loans to maximize invested capital. Instead of paying down principal, they keep more money working in investments that potentially earn higher returns than the loan interest rate.
Principal-and-Interest Loans
Regular payments include both interest and principal reduction. The loan balance decreases over time, eventually reaching zero. Monthly payments are higher but you're building equity and reducing risk.
Principal-and-interest advantages:
Forced debt reduction prevents over-leverage
Lower risk as your loan balance decreases
Eventually debt-free if held to maturity
Better for conservative investors uncomfortable with leverage
Strategic Considerations
Interest-only makes sense when investment returns exceed borrowing costs and you have discipline to manage leverage. If you're investing at 8% returns and borrowing at 5%, keeping maximum capital invested makes mathematical sense.
However, if markets struggle or your investments underperform, interest-only loans can become problematic. You owe the same amount years later with potentially diminished asset values. Balance ambition with prudence.
Offset Account Features
Offset accounts represent one of the most valuable features when identifying the best investment loans, though they're more common with investment property mortgages than securities lending.
How Offset Accounts Work
An offset account is a savings or chequing account linked to your loan. The balance in your offset account "offsets" your loan balance for interest calculation purposes. You only pay interest on the difference.
Example: $200,000 investment loan at 6%. With $50,000 in your offset account, you only pay interest on $150,000. This saves you $3,000 annually (6% of $50,000) while maintaining full access to your $50,000.
Offset account benefits:
Significant interest savings without losing access to funds
Complete flexibility to use offset funds anytime
No penalties for depositing or withdrawing
Maintains tax deductibility of full loan interest
The beauty of offset accounts? They're perfect for holding emergency funds, bonus payments, or short-term savings. Your money reduces borrowing costs while remaining instantly accessible.
Partial vs. Full Offset
Full offset accounts reduce your loan balance dollar-for-dollar. A partial offset might only reduce by 50-70%. Always choose full offset features when available, even if fees are slightly higher—the interest savings typically exceed the costs.
Ontario Availability
Offset accounts are less common in Canada than Australia or the UK, but some lenders offer them, particularly for investment property mortgages. Ask specifically about offset capabilities when comparing the best investment loans.
For healthcare professionals managing variable income streams, offset accounts combined with disability insurance protection create financial flexibility during income interruptions.
Redraw Facilities and Prepayment Options
Flexibility features determine how well your loan adapts to changing circumstances.
Redraw Facilities
Make extra principal payments beyond your required minimum, then "redraw" those extra funds if needed later. This provides flexibility while reducing interest costs when you have surplus cash.
How redraw works: You have a $100,000 investment loan requiring $500 monthly payments. You pay $1,000 monthly for six months, adding an extra $3,000 to principal. Later, you need cash for an opportunity—you can redraw up to $3,000 without requalifying.
Redraw advantages:
Interest savings on accelerated payments
Emergency access to previously paid funds
No penalties for extra payments or redraws
Maintains investment capacity by keeping capital accessible
Some lenders charge redraw fees ($50-200 per transaction) or limit redraw frequency. Others offer unlimited free redraws. When comparing the best investment loans, favor those with minimal redraw restrictions.
Prepayment Options
The ability to make extra payments without penalties saves substantial interest over time. Many fixed-rate loans limit prepayments to 10-20% of the original balance annually. Variable-rate loans typically allow unlimited prepayments.
Important distinction: Redraw facilities return your money. Prepayments without redraw permanently reduce your debt but eliminate access to those funds. For investment loans where maintaining capital access matters, redraw capabilities are crucial.
Tax Deductibility and Documentation
Understanding tax rules separates mediocre from excellent investment loan strategies.
What Makes Interest Tax-Deductible
Canada Revenue Agency allows interest deductions when borrowing is used for income-producing purposes. Borrowed to buy dividend-paying stocks? Deductible. Borrowed to buy your personal residence? Not deductible.
CRA requirements for deductibility:
Income purpose: Must use borrowed funds to earn income
Direct tracing: Clear documentation linking borrowed money to investments
Reasonable expectation: Investment must reasonably produce income
Ongoing income: One-time capital gains may not qualify
Keep meticulous records. Bank statements showing loan proceeds transferring directly to investment accounts provide necessary documentation. Commingling borrowed and personal funds can jeopardize deductibility.
Tax Benefit Calculation
If you're in Ontario's 43% marginal tax bracket and pay $5,000 investment loan interest, your tax deduction saves $2,150 in taxes. Your effective borrowing cost drops from 5% to 2.85%. This dramatically changes investment loan economics.
Common Tax Mistakes:
Borrowing for RRSPs: RRSP contribution loan interest isn't deductible
Personal use: Using borrowed funds for personal expenses eliminates deductibility
Poor documentation: Can't prove purpose means no deduction
TFSA investments: Borrowing to invest in TFSAs makes no sense—interest isn't deductible and gains are already tax-free
According to Canada Revenue Agency guidelines, proper documentation and clear income-producing purpose are essential for interest deductibility.
Loan Security and Collateral Requirements
The security you provide affects rates, terms, and available features for the best investment loans.
Types of Investment Loan Security
Lenders want collateral to protect their interests. The stronger your security, the better rates and terms you'll receive.
Common collateral types:
Investment portfolios: Margin loans secured by your holdings
Real estate: Investment properties or even personal residence
GICs and bonds: Ultra-conservative securities
Business assets: For business investment loans
Margin Loans and Securities-Based Lending
Borrow against your existing investment portfolio with margin loans or investment lines of credit. Rates are typically prime + 0.5-2.0%, depending on your portfolio size and composition.
Margin lending limits by asset:
Canadian blue-chip stocks: 70% loan-to-value
Index funds/ETFs: 50-70% LTV
Bonds and GICs: 80-90% LTV
Foreign stocks: 40-50% LTV
Speculative investments: 0% LTV
Margin Call Risk
If your portfolio value drops below required thresholds, lenders issue margin calls requiring immediate additional collateral or forced liquidation. This risk makes margin lending dangerous during market volatility.
2008 and 2020 saw devastating margin calls force investors to sell quality investments at terrible prices. Only use margin lending if you can weather significant portfolio declines without forced selling.
Real Estate Security
Investment property mortgages typically offer better rates than margin loans because real estate provides tangible security. Expect 80% LTV for investment properties with 20% down payment.
Some Ontario investors use home equity lines of credit (HELOCs) secured by personal residences to invest. This provides excellent rates (prime + 0.5%) but puts your home at risk—use cautiously.
Features That Define the Best Investment Loans
Beyond rates and basic structure, specific features separate average loans from the best investment loans.
Flexible Repayment Options
The ability to adjust payment frequency (weekly, biweekly, monthly) and amounts provides valuable flexibility. Some lenders allow payment holidays or temporary payment reductions during financial difficulties.
Portability
Can you transfer your loan to different investments without penalties? Portability matters when rebalancing portfolios or switching from stocks to real estate investments. Fixed-rate loans often charge penalties for changes; variable-rate loans typically allow free transfers.
Top investment loan features checklist:
No monthly maintenance fees: $10-20 monthly fees add up
Free transfers between investments: Portfolio flexibility without costs
Unlimited extra payments: Accelerate debt reduction without penalties
Low or no redraw fees: Access your extra payments freely
Competitive rates: Within 0.25-0.5% of market leaders
Rate Discounts
Many lenders offer rate discounts for:
Large loans: 0.25-0.50% reduction for loans over $250,000-500,000
Relationship banking: Discount for holding other products (accounts, investments, insurance)
Automatic payments: 0.10-0.25% off for pre-authorized payments
Professional discounts: Healthcare professionals, lawyers, and accountants often qualify
Customer Service and Accessibility
Can you access loan information online 24/7? Reach a real person quickly when problems arise? Small trust companies might offer competitive rates but terrible service. Major banks provide better service but potentially higher rates.
Investment Loan Strategies for Different Goals
The best investment loans vary based on what you're trying to achieve.
Building Investment Portfolios
For accumulating diversified stock and bond portfolios, margin loans or investment lines of credit offer maximum flexibility. Variable rates keep costs low, and interest-only payments maximize cash flow for additional investments.
Strategy: Borrow conservatively (30-40% LTV) to avoid margin calls, use variable rates for lower costs, and make interest-only payments to maximize invested capital. As your portfolio grows, your borrowing capacity increases.
Real Estate Investment
Investment property mortgages should emphasize stability and tax optimization. Fixed rates protect against rising rates, and principal-and-interest payments build equity.
Strategy for rental properties:
Use 5-year fixed rates for payment certainty
Choose interest-only if cash flow tight initially
Refinance as property appreciates to fund additional purchases
Maximize offset accounts with rental income deposits
Business Investment
Business expansion loans need flexibility as businesses evolve. Lines of credit with redraw capabilities provide working capital flexibility while minimizing interest costs.
Tax-Efficient Wealth Building
High-income Ontario earners maximizing tax deductions should prioritize loans with maximum deductible interest. Interest-only variable-rate loans generate the highest tax deductions.
For incorporated professionals, corporate investment strategies can complement personal investment loans for comprehensive wealth building.
Risks and Risk Management
Investment loans amplify returns—and risks. Proper risk management separates successful leveraged investors from cautionary tales.
Interest Rate Risk
Variable rates expose you to payment increases. A 2% rate increase on a $200,000 loan adds $4,000 annual interest costs. Can your cash flow handle this? If not, fixed rates provide essential protection.
Market Risk
Borrowing to invest means you're exposed to full market downside. A 30% market correction on a $300,000 leveraged portfolio means $90,000 in losses while still owing the full loan balance.
Key risk management strategies:
Conservative leverage: Borrow 30-50% of portfolio value, not 70%+
Emergency reserves: Maintain 6-12 months of loan payments in cash
Diversification: Don't concentrate borrowed funds in single investments
Stop-loss discipline: Have predetermined points to reduce leverage
Liquidity Risk
Can you access cash quickly if needed? Investments might be illiquid during market stress. Offset accounts and redraw facilities provide liquidity buffers that pure investment holdings don't offer.
Income Interruption Risk
Job loss, disability, or business struggles can make loan payments impossible. For Ontario professionals, combining investment strategies with critical illness insurance protects against income disruptions that could force investment liquidation.
Forced Liquidation
The worst outcome: needing to sell investments at terrible prices to meet loan obligations. This destroys wealth and eliminates future recovery opportunities. Always maintain buffers to avoid forced selling.
Comparing Ontario Investment Loan Providers
Different lenders offer varying rates, terms, and features when seeking the best investment loans.
Major Banks
Big five banks (RBC, TD, Scotia, BMO, CIBC) offer competitive rates, extensive branch networks, and relationship discounts. They provide stability and comprehensive services but may not have the absolute lowest rates.
Bank advantages:
Relationship discounts: Multiple products mean better rates
Branch access: In-person service across Ontario
Diverse products: Everything from margin loans to property mortgages
Financial planning: Integrated advice services
Online Lenders and Fintechs
Online-only lenders often advertise the lowest rates with streamlined applications. However, service can be limited, and features like offset accounts are rare.
Credit Unions
Ontario credit unions sometimes offer competitive rates with personalized service. They're particularly strong for real estate investment loans but may have limited securities lending options.
Wealth Management Firms
Full-service wealth managers provide integrated lending tied to investment management. Rates might be higher, but comprehensive planning adds value. Margin loans through wealth managers often have better terms than bank margin accounts.
Comparison Shopping Tips:
Get quotes from 3-5 lenders to establish market rates
Compare all-in costs including fees, not just advertised rates
Evaluate features beyond rate—flexibility matters
Consider relationship value of consolidated banking
Interest rates change frequently. Current best rates are available through financial comparison websites, but always verify directly with lenders.
Application Process and Approval Requirements
Understanding what lenders need streamlines applications for the best investment loans.
Documentation Requirements
Lenders assess your ability to service debt and the quality of your collateral. Prepare comprehensive documentation to speed approval.
Typical documentation needed:
Proof of income: Tax returns, pay stubs, financial statements
Investment details: Portfolio statements, property appraisals
Credit history: Authorization for credit bureau checks
Asset verification: Bank statements, investment confirmations
Investment plan: Some lenders want to understand your strategy
Credit Score Importance
Investment loans require strong credit. Expect minimum credit scores of 680-700 for competitive rates. Excellent credit (750+) qualifies for best rates and maximum features.
Income Requirements
Lenders verify you can service debt from regular income, not just investment returns. They typically require debt service ratios under 40-44% (total debt payments divided by gross income).
Approval Timeline
Simple margin loans against existing portfolios can be approved in 24-48 hours. Investment property mortgages take 2-4 weeks with property appraisals and full underwriting. Lines of credit fall somewhere in between.
Pre-Approval Benefits
Getting pre-approved before finding investments provides certainty and negotiating power. You know exactly how much you can borrow and at what rate, making investment decisions clearer.
Long-Term Strategy and Portfolio Management
The best investment loans integrate into comprehensive, long-term wealth-building strategies.
Debt Recycling Strategy
Popular in Australia, debt recycling involves strategically converting non-deductible personal debt into deductible investment debt over time. Pay down your mortgage, then borrow against home equity to invest—converting personal debt into tax-deductible investment debt.
This advanced strategy requires careful execution and professional guidance but can dramatically improve after-tax returns for disciplined investors.
Dollar-Cost Averaging with Leverage
Rather than borrowing a lump sum, some investors establish lines of credit and draw funds gradually to invest systematically. This reduces market timing risk while building leveraged positions over time.
Rebalancing with Loan Flexibility:
Draw additional funds when markets drop (buying low)
Make extra payments when markets peak (reducing leverage)
Use redraw features to dynamically adjust leverage
Maintain target allocation between debt and equity
Portfolio Growth and Leverage Management
As your portfolio grows, maintain consistent leverage ratios. A $200,000 portfolio with $100,000 borrowed (50% leverage) that grows to $300,000 now has only 33% leverage. Some investors borrow additional funds to maintain leverage; others let it naturally decline as portfolios grow.
Exit Strategies
Plan how you'll eventually eliminate investment debt. Options include gradual principal payments, lump sum payments from bonuses or inheritances, or liquidating investments when goals are achieved. Never assume markets will bail you out—have deliberate exit plans.
For business owners approaching retirement, coordinating investment loan repayment with corporate insurance strategies creates comprehensive wealth transition plans.
Common Investment Loan Mistakes
Avoid these costly errors when using the best investment loans.
Over-Leveraging
Borrowing the maximum available amount amplifies risk beyond acceptable levels. Conservative leverage (30-50% LTV) weathers market storms; aggressive leverage (70%+ LTV) invites disaster during corrections.
Ignoring Total Costs
Focusing only on interest rates while ignoring fees, penalties, and lost flexibility costs money. A loan at 5.5% with perfect features beats one at 5.0% with $500 annual fees and prepayment penalties.
Critical mistakes to avoid:
Borrowing for TFSAs: Interest isn't deductible—makes no sense
Short-term speculation: Investment loans need long-term horizons
No emergency reserves: Maintain cash buffers for payment security
Ignoring tax implications: Poor documentation eliminates deductibility
Emotional Decision Making
Fear of missing out drives terrible leverage decisions. Borrowing to chase hot investments or increasing leverage during market euphoria typically ends poorly. Disciplined, systematic approaches beat emotional reactions.
Inadequate Insurance Protection
Borrowing to invest without protecting your income through disability insurance or life insurance exposes families to catastrophic risk. Comprehensive protection matters more when you're leveraged.
Commingling Funds
Using investment loans for personal expenses destroys tax deductibility. Maintain strict separation between borrowed investment funds and personal money. A single $500 personal withdrawal from your investment line of credit can jeopardize deductibility of all interest.
Making Your Investment Loan Decision
Choosing the best investment loans requires careful evaluation of your complete financial situation.
Assessment Framework
Before borrowing to invest, honestly evaluate:
Risk tolerance: Can you handle 30-40% portfolio declines without panic?
Income stability: Is your income reliable enough to service debt?
Investment knowledge: Do you understand what you're investing in?
Time horizon: Do you have 10+ years for investments to recover from downturns?
Emergency reserves: Do you have 6-12 months of expenses saved?
If you answered "no" to any of these, reconsider leveraged investing or use much more conservative leverage ratios.
Professional Guidance
Investment loan decisions involve complex interactions between taxation, investments, lending, and risk management. Work with qualified advisors including financial planners, accountants, and potentially lawyers for large loans.
Starting Small
New to leveraged investing? Start with modest leverage (20-30% of portfolio value) to understand how it feels managing borrowed funds through market volatility. You can always increase leverage later; reducing it during losses is painful.

FAQs
Q: What interest rate should I expect on investment loans in Ontario?
A: Rates vary by loan type and security. Margin loans: prime + 0.5-2.0% (currently 6.0-7.5%). Investment property mortgages: 5.5-7.5% depending on fixed vs variable. HELOCs: prime + 0.5% (around 6.5%). Your credit score and relationship banking affect rates significantly.
Q: Can I deduct investment loan interest on my taxes?
A: Yes, when borrowed funds are used for income-producing investments. Interest on loans for dividend-paying stocks, rental properties, or business investments is deductible. Interest for RRSP contributions, TFSA investments, or personal residences is not deductible.
Q: How much can I borrow against my investment portfolio?
A: Typically 50-70% of portfolio value for diversified stock portfolios, 80-90% for bonds and GICs. Borrowing capacity depends on investment quality—blue-chip stocks support more borrowing than speculative holdings. Never borrow the maximum available; maintain buffers to avoid margin calls.
Q: What's an offset account and how does it save money?
A: An offset account is a linked savings account where your balance reduces the loan amount you pay interest on. If you have a $200,000 loan and $50,000 in your offset account, you only pay interest on $150,000. You save interest while maintaining full access to your $50,000.
Q: Should I use interest-only or principal-and-interest payments?
A: Interest-only maximizes cash flow and tax deductions but doesn't reduce debt. Principal-and-interest forces debt reduction and lowers risk. Conservative investors should choose principal-and-interest. Aggressive investors with strong cash flow management can use interest-only strategically.
Build Wealth Strategically with the Right Loan
The best investment loans amplify your wealth-building strategy when structured properly and managed prudently. Understanding variable versus fixed rates, leveraging offset accounts and redraw features, maximizing tax deductions, and maintaining conservative leverage ratios separates successful leveraged investors from cautionary tales.
Investment loans aren't for everyone. They require discipline, strong income, adequate emergency reserves, and genuine risk tolerance. But for investors who meet these criteria, properly structured investment loans can significantly accelerate wealth accumulation through enhanced returns and substantial tax benefits.
The key is matching loan features to your specific situation—your income stability, risk tolerance, investment timeline, and financial goals. Variable rates suit stable incomes and risk-tolerant investors. Fixed rates protect conservative investors from payment shock. Offset accounts maximize flexibility while reducing costs.
Start conservatively with leverage ratios around 30-40% of portfolio value. Maintain substantial emergency reserves. Document everything for tax deductibility. And work with qualified financial, tax, and legal advisors to structure loans that enhance your wealth without exposing you to unacceptable risk.
Whether you're building an investment portfolio, purchasing rental properties, or funding business growth, the right investment loan strategy—combined with comprehensive financial planning and appropriate insurance protection—creates a foundation for long-term financial success.
