Frequently asked questions

Why is my maximum lower than expected?

Debt ratios and stress-test rules can reduce qualifying amounts.

Does down payment affect affordability?

Yes. A larger down payment reduces the mortgage amount and ratios.

Is this a pre-approval?

No. It is an estimate. Lenders must verify documents for approval.
