Choose a shorter amortization — 25 years instead of 30 saves $131,200 on a $700K mortgage at 5%
Make accelerated bi-weekly payments — saves ~$58,800 and cuts 3 years off your amortization
Use prepayment privileges — a $25,000 annual lump sum saves ~$90,000+ in interest
Shop for a lower rate — 0.25% lower saves approximately $31,500 over 25 years
Increase payments when you can — a $350/month increase saves ~$32,000 in interest
Who carries a $700,000 mortgage?
A $700,000 mortgage, with a typical 10–20% down payment, finances a home priced roughly $775,000–$875,000 — a range that lines up almost exactly with Ontario’s current provincial average of $811,868 (-4.8% YoY, per the most recent full CREA breakdown). It also fits Hamilton’s July 2026 benchmark of $728,200 (-5.1% YoY) with a smaller down payment, or Ottawa’s average of $683,308 (-1.6% YoY) with minimal down. In the GTA specifically, where the average has climbed to $1,003,956, this mortgage size buys a townhouse rather than a detached home. Qualifying requires roughly $155,000–$185,000 in household income, which generally means two established professional incomes. At this mortgage size, every fraction of a percentage point matters: a 0.25% rate difference costs or saves over $31,000 in total interest over 25 years, so shopping lenders or using a broker is not optional — it’s essential.
