The Smarter Way to Understand Your Mortgage Affordability
GDS/TDS Calculation
We calculate your exact Gross Debt Service and Total Debt Service ratios for your income, debts, and target purchase price. You know your number before making any offers.
Stress Test Analysis
We run your full qualification at the stress test rate (contract rate + 2%) so you know exactly how much you can borrow before you waste time on properties you can't finance.
Self-Employed Income Optimization
Self-employed borrowers leave $50K–$150K in mortgage approval on the table by under-presenting income. We work with you to properly document gross income with all eligible add-backs.
50+ Lenders Compared
Different lenders allow different TDS ratios and use different income calculations. We find the lender with the highest approval for your specific income and debt profile.
Pre-Approval Letter
We provide a formal pre-approval letter showing your maximum purchase price. This gives you negotiating credibility when making offers in competitive markets.
Rate Holds Up to 120 Days
Once pre-approved, we lock your rate for up to 120 days. Your affordability doesn't change if rates rise while you search.
Debt Optimization Strategy
Sometimes paying off one debt increases your TDS enough to unlock $30,000–$80,000 in additional approval. We model your debt paydown scenarios.
FSRA Licensed Brokerage #13763
Fully regulated Ontario mortgage brokerage — we are legally required to present your full affordability picture, not a bank's target price.
First-Time Buyer Programs
Eligible first-time buyers may qualify for 30-year amortization, FHSA/HBP contributions, and CMHC insurance — all of which affect your affordability calculation.

Mortgage Affordability Ontario — FAQs
Affordability is based on two ratios: GDS (housing costs ÷ gross income, max 39%) and TDS (all debt payments ÷ gross income, max 44%). You must qualify at the stress test rate: contract rate + 2%, minimum 5.25%. We calculate your exact limits — free.
The stress test requires you to qualify at your contract rate + 2% (or 5.25%, whichever is higher). If your rate is 4.04%, you qualify at 6.04%. This reduces your approved amount by roughly 15–20% compared to qualifying at the actual rate.
GDS (Gross Debt Service) ratio is your annual housing costs (mortgage P&I, property taxes, heating, 50% condo fees) divided by gross annual income. Maximum is 39%. Exceeding this is the most common reason for mortgage decline.
TDS (Total Debt Service) ratio adds all other debt payments (car loans, credit cards, student loans) to housing costs. Maximum is 44%. Paying off a $500/month car loan can unlock $50,000–$80,000 in additional mortgage approval.
At 4.04% rate, with no other debts, an income of $100,000 qualifies for approximately $550,000–$600,000 (25-year amortization). With significant debts, this drops. With co-applicant income added, this increases. We calculate your specific number — free.
Yes. Self-employed borrowers qualify using a 2-year average of line 15000 (total income) from T1 Generals, plus eligible add-backs (business use of home, depreciation, etc.). B-lenders use gross revenue; stated income programs also exist. We specialize in self-employed qualification.
Car loans have the biggest impact — a $600/month car payment reduces mortgage approval by $80,000–$100,000. Credit card minimum payments, student loans, and other property carrying costs also reduce TDS. We model the exact impact of each debt.
A mortgage pre-approval requires a hard credit pull, which can reduce your score by 5–10 points temporarily. However, multiple mortgage inquiries within a 45-day window are typically treated as a single inquiry by credit bureaus. We tell you the optimal timing strategy.
