Who carries a $300,000 mortgage?

A $300,000 mortgage is the bread-and-butter Canadian mortgage in the Prairies and Atlantic Canada specifically — not a generic “average” borrower profile. With 10–20% down, it finances a home priced roughly $335,000–$375,000, which lines up almost exactly with Regina’s July 2026 benchmark price of $343,500 (+3.0% YoY), one of Canada’s most affordable major markets. It also sits comfortably below Winnipeg’s benchmark of $392,900 and Moncton’s $385,200, meaning a $300K mortgage buys with room to spare in both cities. At 5% over 25 years the monthly payment is about $1,745, requiring roughly $75,000–$85,000 in household income — achievable on a single income in all three markets. Because this mortgage size is well within CMHC-insured limits, buyers also get access to the lowest available insured rates.
