Who carries a $400,000 mortgage?
A $400,000 mortgage is common among first-time buyers in Canada’s mid-tier markets and among move-up buyers who bring significant equity to a larger purchase. If you are buying a $420,000 home with 5% down, or a $500,000 home with 20% down, you land in this range. In Calgary, Edmonton, and Ottawa, that covers a solid family home; in the GTA and Lower Mainland it’s the starting point for condos in desirable neighbourhoods. The household income required is roughly $95,000–$120,000 depending on your down payment and debts, which places most borrowers in the dual-income or senior-professional bracket. At this mortgage size, the difference between a 25-year and 30-year amortization is about $75,200 in extra interest — a decision that deserves careful thought before signing.
Where a $400,000 mortgage applies
- First-time buyers in growing cities — homes in Calgary, Edmonton, Ottawa, or Halifax
- Suburban homes — a $500K home with 20% down cements this as the sweet spot
- Condo purchases in major markets — entry-level condos in Toronto or Vancouver suburbs
- Move-up buyers — selling a starter home with equity and buying something larger
