? How 2025 Mortgage Rates Are Shaping the Custom Home Market

1. Borrowing Costs Are Easing

As of mid-2025, 5-year fixed mortgage rates in GTA range from 3.9% to 4.2%.
Lower rates make it easier for buyers to secure construction loans and mortgages.
Builders also benefit from more affordable financing for land and project costs.

2. Demand is Rebounding

High rates in 2022–2023 cooled custom home demand.
Rate stabilization is boosting buyer confidence, but affordability still plays a limiting role.

3. Home Equity Financing Grows

Many homeowners fund builds via home equity loans or mortgage refinancing.
Lower rates improve access to capital for major projects like custom homes or extensive renovations.
