How does my debt-to-income ratio affect
mortgage approval?
Clickbait reboot of the question: This one number will make or break your mortgage approval — how your debt-to-income ratio controls whether lenders say yes or no
Quick answer up front
Your debt-to-income ratio (DTI) — in Canada usually expressed as Gross Debt Service (GDS) and Total Debt Service (TDS) — is the single strongest numerical gatekeeper lenders use to approve a mortgage. Hit the lender’s ratio thresholds and you qualify more easily. Miss them and you face higher rates, bigger down payments, or a denial. In Georgetown, ON, this decides whether you can move smoothly from selling a home to buying the next one.
Why this matters now in Georgetown, Ontario
Georgetown’s market is competitive and prices can move fast. Many sellers are also buyers. If you don’t understand how lenders read your debt load and income, you can price your home wrong, lose leverage, or fail to qualify for the next mortgage. A strong DTI equals more buying power and faster closings. A poor DTI creates delays and lost sales.
What lenders actually look at: DTI, GDS and TDS explained
- Debt-to-Income Ratio (DTI): A broad term that describes how much of your monthly income goes to debt payments.
- Gross Debt Service (GDS): In Canada, GDS focuses on housing costs — mortgage principal, interest, property taxes, heating and 50% of condo fees — divided by gross monthly income.
- Total Debt Service (TDS): TDS includes all debts — housing plus car loans, credit cards, student loans, lines of credit — divided by gross monthly income.
Most Canadian lenders set limits for GDS and TDS. If you’re applying for mortgage default insurance (CMHC or other insurers) the typical caps are:
- GDS: up to 39%
- TDS: up to 44%
Conventional lenders vary, but many still use similar benchmarks. Strong credit, higher down payment, or a higher income can sometimes extend those limits.
How the mortgage stress test ties in
Lenders apply the stress test: your qualifying rate is the higher of your contract rate plus 2% or the Bank of Canada benchmark rate. This pushed required income higher and tightened the effective DTI. It means that even with a low advertised rate, lenders simulate higher payments. That’s why sellers in Georgetown should not assume pre-approval numbers without a local lender check.
What counts as debt — know the line item details
Lenders total your monthly obligations. That list commonly includes:
- Current mortgage or rent
- Property taxes and heating costs
- Monthly condo fees (50% often used)
- Car and lease payments
- Minimum credit card payments
- Student loans and lines of credit
- Alimony or child support payments
Not counted: groceries, gas, utilities, discretionary spending. But these influence how lenders view affordability in detailed underwriting.
Practical thresholds for Georgetown buyers and sellers
- Safe zone: GDS under 32%, TDS under 40% — lenders see this as low risk. You’ll have options and negotiating leverage.
- Typical ceiling for insured mortgages: GDS 39% / TDS 44% — workable but tighter.
- Stretch zone: TDS above 44% — possible with alternative lenders, larger down payment, or a co-signer, but expect higher costs and tougher approval.
If you’re selling a home in Georgetown and planning to buy, aim for the safe zone. It keeps financing predictable during the sale-to-purchase window.
How your DTI affects mortgage approval and home selling strategy
- Offer strength: Lower DTI = stronger pre-approval = faster closing. Buyers with clean ratios win in multiple-offer situations.
- Timing risk: If you sell before confirming financing for your next home, a weak DTI can force a price cut or a contingency-laden sale.
- Bridge financing and carrying costs: Sellers who need bridge loans or short-term financing will be evaluated on the same ratios. High DTI can kill bridge approvals or raise fees.
- Pricing decisions: Sellers who can’t re-buy at their target price because of DTI limits may need to adjust sale strategy — hold, rent-back, or accept lower offers to avoid a failed move.
Steps to lower your DTI quickly (tactics that work)
- Pay down high-interest credit cards first. Minimum payments still count; reducing balances lowers monthly obligations.
- Refinance or consolidate expensive consumer debt into a lower-rate loan — this can reduce minimum monthly payments and improve TDS.
- Increase documented income: overtime, new job with pay stubs, or rental income verified on tax returns. Lenders require proof.
- Delay large purchases or new lines of credit before applying for a mortgage.
- Increase down payment: reduces mortgage amount and housing costs.
- Ask for higher qualifying income where legitimate (e.g., vacation rental or freelance work with two years of tax returns).
- Use a qualified co-borrower or guarantor to reduce your effective DTI.
- Talk to a mortgage broker — they shop lenders and can find ones with flexible overlays for Georgetown buyers.
These are actionable moves. Do several in parallel for the fastest impact.
What to expect during mortgage approval in Georgetown
- Pre-approval: Lenders issue a conditional approval based on credit, income, down payment and estimates for GDS/TDS.
- Full approval: After an accepted offer, underwriters validate income and debts, order appraisal, and finalize. Small differences in DTI can change rate offers.
- Timelines: Pre-approval takes days. Full approval takes 1–3 weeks normally. Delays occur when DTI is near the lender’s ceiling.
If you’re selling and buying in the same market window, align sale closing dates with lender timelines. Don’t assume a pre-approval guarantees full approval — stress test and document verification matter.
Local market note: Georgetown, ON specifics
- Average price ranges and inventory swings in Georgetown make timing important. Competitive listings favour buyers who are fully qualified.
- Local lenders and mortgage brokers know which underwriting teams at major banks are more flexible with GDS/TDS on Georgetown properties.

Partnering with an agent who understands local numbers shortens the approval loop and protects your sale proceeds.
Simple checklist to protect your sale and the next purchase
- Get a local pre-approval with stress-tested numbers.
- Run a quick DTI audit: list all debts, monthly payments, gross income. Calculate GDS and TDS.
- If TDS > 44%, start remediation now (pay down debt, consolidate, increase down payment).
- Time your listing and closing to buyer’s mortgage approval windows.
- Keep financial documents ready: pay stubs, T4s, notices of assessment, and statements for all debts.

FAQ — quick answers for sellers and buyers in Georgetown
What is a good DTI for qualifying for a mortgage in Georgetown?
Aim for GDS under 32% and TDS under 40% for strong options. Insured mortgages allow up to GDS 39% and TDS 44%, but that’s tighter and gives lenders less wiggle room.
How does the stress test change my DTI?
The stress test raises the rate used to calculate mortgage payments. That increases your housing payment in the GDS/TDS formulas, making your ratios look worse. Always use stress-tested numbers for planning.
I’m selling my home — how will my DTI affect my sale?
If you need mortgage financing for your next home, your DTI impacts whether you can buy quickly after the sale. Weak DTI may force you to accept lower offers, delay moving, or seek bridge financing with higher costs.
Can I get a mortgage with a high DTI?
Sometimes. Alternatives include higher down payment, private lenders, co-signers, or a long-term plan to reduce debt. Expect higher rates and stricter terms.
What documents should I prepare now?
Recent pay stubs, two years of tax returns (if self-employed), T4s, bank statements, statements for credit cards/loans, property tax and heating bills, and condo documents if applicable.
How long does it take to improve my DTI?
Paying down credit cards can affect numbers in 30–60 days. Proving higher income can take a new paycheque cycle or tax return. Consolidation or refinancing may take weeks.
Does home equity lower my DTI?
Home equity doesn’t directly change monthly debt obligations until you refinance and use equity to pay down other debts. A cash-out refinance can lower TDS if used to pay off high monthly payments.
Should I sell first or buy first in Georgetown?
There’s no one-size answer. If your DTI is strong and you have a pre-approval, buying first can be fine. If your DTI is tight, sell first and secure your financing plan before committing to buy.
