Quick Answer
BC minimum down payment in 2026: 5% on homes under $500,000. 5% on first $500K + 10% on the portion from $500K up to $1.5M. 20% minimum on homes $1.5M and over (mortgage insurance isn't available at that price, which takes in many Coquitlam detached homes). On a $1.5M Coquitlam home, that's $300,000 minimum. Plus closing costs of 2-4% (legal, property transfer tax, GST on new builds, inspection, moving). All-in, plan for the down payment plus another $20K-$50K in closing on most Tri-Cities purchases.
