What borrowing capacity really measures
The provider is not looking for the highest possible amount but for the monthly payment your budget can carry over time. That payment, converted using the term and the profit or rental rate, then gives the property price you can aim for.
The GDS ratio: the share of income going to housing
The gross debt service ratio adds the payment, municipal and school taxes, heating and half of any condo fees, then divides the total by gross income. For an insured loan, the usual ceiling is 39%.
The TDS ratio adds all your other debts
The total debt service ratio takes housing costs and adds car payments, cards, student loans and other commitments. For an insured loan it typically tops out at 44%, but each halal provider sets its own thresholds.
How cards and lines of credit are counted
Even a card paid off every month may be counted at a percentage of the balance, often 3%. Lowering unused limits and closing unnecessary accounts before applying can noticeably improve your TDS ratio.
The qualifying rate and the rate-increase test
Federally regulated lenders qualify borrowers at the higher of 5.25% or the contract rate plus two points. Halal providers, often outside that framework, apply their own buffer, so ask which rate is used in the calculation.
Why the profit rate weighs as much as interest
Under murabaha or ijara, the payment depends on the profit rate or rent set by the provider. Mathematically, a higher rate reduces the amount you can finance just as interest would, even though the nature of the contract differs.
An indicative example for a Quebec household
With gross income of $90,000 a year, a 39% GDS allows about $2,925 a month for housing. If taxes and heating cost $500, roughly $2,425 remains for the payment to the provider, for illustration only.
Testing several scenarios before house hunting
Our halal home financing calculator lets you compare several terms and profit rates. The result remains an estimate, since each provider adjusts its ratios, minimum down payment and safety margin to its own risk profile.
The down payment shifts your purchase ceiling
For the same monthly payment, a larger down payment directly raises the price you can reach. Because many halal providers require more than the conventional minimum, read our page on the down payment for halal financing before setting a budget.
Quebec closing costs you pay in cash
Land transfer duties, known as the welcome tax, notary fees, the inspection and the certificate of location come on top of the price. They are generally not financed, so savings that only cover the down payment reduce your real capacity.
Eligible income: employees, self-employed and rents
Base salary from a permanent job counts in full, while bonuses, overtime and business income are often averaged over two years. For a plex, part of the rental income may be added depending on the provider.
From estimate to a written answer
Once your ratios are known, a halal financing pre-approval confirms the amount in writing, subject to the property appraisal. For provincial specifics, our guide to Islamic home financing in Quebec completes the process.
Working out your halal borrowing capacity in six steps
- Add up the household's stable gross annual income, using a two-year average for bonuses and self-employment income.
- List every monthly debt: car, student loan, support payments, and cards or lines counted at a percentage of the balance.
- Estimate municipal and school taxes, heating and, for a condo, half of the condo fees for the type of property you want.
- Apply the provider's GDS and TDS ratios to find the maximum monthly payment your budget can absorb.
- Convert that payment into a financeable amount using the qualifying rate or safety margin the halal provider applies.
- Add your available down payment, subtract the welcome tax and notary costs, then compare the result with local prices.
Items that shrink your buying power in Quebec
| Item | Effect on capacity | Order of magnitude |
|---|---|---|
| Municipal and school taxes | Included in GDS and TDS | Depends on the municipality and assessed value |
| Condo fees | Half included in the ratios | Set by the syndicate of co-owners |
| Car loan or lease payment | Fully included in TDS | Actual contract amount |
| Credit cards and lines | Percentage of balance included in TDS | Often 3% of the balance, indicative |
| Welcome tax and notary | Paid in cash, reduce available savings | Depends on price and municipality |
| Provider safety margin | Reduces the financeable amount | Actual rate plus a buffer, to confirm |
Proof needed to establish your financing capacity
- Employment letter stating position, seniority and salary
- Recent pay stubs
- Revenu Québec and CRA notices of assessment for the last two years
- T4 slips and Relevé 1
- Statements for cards, lines and current loans
- Bank statements proving savings for the down payment and fees
- Tax bill or listing sheet for the target property
Mistakes that skew the capacity calculation
- Calculating capacity on net rather than gross income, then comparing incompatible results from one provider to another.
- Forgetting school taxes, heating or condo fees, which overstates the affordable payment by several hundred dollars.
- Signing a new car financing deal just before applying, which inflates the TDS ratio at the very moment of review.
- Assuming the advertised profit rate is used in the calculation when the provider may qualify the file at a higher rate.
- Putting all savings into the down payment without setting aside the welcome tax, notary costs and an emergency cushion.
Borrowing capacity and Islamic financing: targeted answers
Does a halal provider calculate capacity like a bank?
The logic is the same: income, debts, housing costs and a safety margin. The thresholds vary, though. Since many halal providers fall outside federal qualifying-rate rules, ask in writing which ratios and rate they apply.
Do family allowances count as income?
Some providers count them partially when payments will continue for several more years, others do not. It is an internal policy. Provide the payment notices and ask whether these amounts are retained before relying on them in your budget.
Does a co-applicant increase capacity?
Yes, their income is added, but so are their debts. Depending on the structure, they become a co-owner or co-obligor and are liable for the whole term. Each person should consult a notary or independent advisor before signing.
Why does my capacity drop when the profit rate rises?
Because your ratios cap the monthly payment. If the profit rate or rent rises, more of that payment goes to the provider and the amount you can finance falls, even on the same income.
Should an interest-free student loan be included in debts?
Yes. Even with no interest, the scheduled monthly payment enters the TDS ratio. If repayment has not started, the provider may estimate a notional payment from the balance, according to its internal policy.
