Answer

My payments feel affordable. Why are my debt ratios too high for the mortgage?

Short answer

Your household budget and a lender’s qualification calculation answer different questions. The lender uses verified income, prescribed housing costs, existing obligations and a qualifying mortgage payment under its policy. It may include payments that feel temporary or exclude income you regularly receive. Start by reconciling every income and debt item rather than arguing only that rent has been paid on time. Your broker can then test accurate balances, permitted exceptions, debt repayment, a smaller mortgage, another A program or an alternative route with costs and risks clearly shown.

The client problem behind the question

The borrower has never missed rent and may already pay an amount close to the proposed mortgage, but the lender says the ratios fail. The client wants the lived payment history to count. It can support the overall story, but it does not replace the lender’s calculation.

Start with the income or obligation the lender actually used

List gross qualifying income, proposed mortgage payment, property tax, heating, condo costs and every monthly obligation used by the lender. Verify credit balances and payments, support obligations and co-signed debts. Identify income excluded from the worksheet and why. Then run a household budget using net income and real expenses; passing a ratio does not prove the payment is comfortable.

A useful review separates verified facts, lender-specific policy, assumptions and Rajiv’s professional interpretation. FCAC explains general mortgage preparation, while OSFI and FSRA regulate within their mandates. None of them writes an individual lender’s complete income policy. The intended lender’s current program guide and underwriting decision remain essential.

A practical Ontario example

Illustration only: A family pays $3,100 rent and saves monthly, but the mortgage calculation also includes a vehicle loan, line of credit, property tax and condo fees. One bonus is excluded because its history is short. The broker corrects an overstated credit payment, tests responsible debt repayment without consuming closing funds and recalculates the mortgage. If A ratios still fail, a B option is compared using its actual payment and fees.

The example is not an approval, rate quote or identifiable client file. A different document, property, debt or closing date can change the result.

Can the original A-lender route still work?

An A lender may accept corrected debts, supported income or a documented exception under its policy. Reducing the purchase price or increasing the down payment can also work, but borrowed funds may add another obligation.

The first lender should be tested where time permits because it already knows the file. The broker should identify the exact missing requirement before asking for an exception or moving the application.

Could another A lender view the file differently?

Possibly, when another institution’s normal policy genuinely fits the verified facts. The strategy is lender matching, not hiding weak information. Income, debts, credit, down payment, property and timing must all be disclosed and accepted.

Where an alternative or B lender may fit

An alternative lender may allow a wider ratio range or different income treatment. The real budget must still support the higher rate and possible fees. The exit should identify which debt or income issue will change by renewal.

Alternative lending is its own solution. Compare interest rate, lender and brokerage fees, payment, amortization, prepayment terms, property requirements and the realistic date for returning to A lending.

Where an MIC or private lender may fit

Private lending based mainly on equity can bypass an A-ratio limit but cannot bypass cash-flow reality. Use it only when payment, full costs and exit remain reasonable under a stressed budget.

An MIC uses professionally managed pooled investor capital; an individual private lender uses private capital. Terms may be short, interest-only or amortized, and open, partially open or closed depending on the lender. Calculate the net advance, all fees, legal costs, monthly payment, maturity balance and exit before accepting either.

What should the client avoid?

  • Do not alter income documents, omit debts or describe transfers as earnings.
  • Do not apply repeatedly without knowing which policy difference is being tested.
  • Do not use closing funds to repay debt until the remaining cash requirement is recalculated.
  • Do not assume an accountant’s letter or broker explanation forces lender acceptance.
  • Do not choose higher-cost financing without testing affordability and exit risk.

Questions for the mortgage review

  1. Which income and debts did the lender use?
  2. What document or history is missing?
  3. Is the concern lender policy, insurer policy or incomplete evidence?
  4. What A-lender policy difference would make another application worthwhile?
  5. What does a B, MIC or private route cost, and what creates the exit?

What can change the answer?

The answer can change with usable income, qualifying rate, mortgage amount, taxes, heating and condo costs, credit payments, support obligations, down payment, lender ratios, exceptions and household budget.

Scope note: Debt-service limits and exceptions differ by lender and mortgage type. Any calculation must use the intended lender’s current policy.
