Buying · Châteauguay · cash 2026
All the money needed to buy the median house in Châteauguay in 2026: down payment, tax on the CMHC premium, welcome tax, notary, inspection, with the 20% scenario, the condo and 2016 for comparison.
To buy the median house in Châteauguay, sold for $520,000 from January to September 2026, plan for $36,985 to $39,485 in cash. The big piece is the minimum down payment (5% of the first $500,000 and 10% of the rest): $27,000. Add $5,910 of welcome tax (Châteauguay's 2026 grid), $1,775 of Québec tax on the $19,720 CMHC premium (the premium goes into the loan, the tax is paid in cash) and $2,300 to $4,800 for the notary, inspection and appraisal. A first-time buyer then recovers up to $5,228 through Québec's welcome tax credit, bringing the bill to about $33,007. With 20% down to avoid the premium, it takes $112,210 to $114,710 instead. In 2016, the minimum down payment, premium tax and welcome tax on the median house ($213,000) added up to $13,194; in 2026, $34,685 (+163%). Assumptions: Centris median price of single-family houses and condos sold (January to September 2026), federal minimum down payment (5% of the first $500,000, 10% of the rest, 20% from $1.5M), CMHC premium on the schedule in force since 2017 (added to the loan), Québec's 9% tax on the premium (paid in cash), welcome tax on the city's 2026 grid, notary $1,800 to $3,500 for a house ($1,500 to $2,800 for a condo), inspection $500 to $800, appraisal $0 to $500 depending on the lender.

How to read these numbers
Assumptions: Centris median price of single-family houses and condos sold (January to September 2026), federal minimum down payment (5% of the first $500,000, 10% of the rest, 20% from $1.5M), CMHC premium on the schedule in force since 2017 (added to the loan), Québec's 9% tax on the premium (paid in cash), welcome tax on the city's 2026 grid, notary $1,800 to $3,500 for a house ($1,500 to $2,800 for a condo), inspection $500 to $800, appraisal $0 to $500 depending on the lender. The calculated items (down payment, premium tax, welcome tax) follow the median price; the fixed costs are 2026 ranges, hence a total as a range. The comparison with 2016 covers the calculated part only, at a constant 2026 grid. Adjustments repaid to the seller (prepaid municipal and school taxes, heating oil, condo fees), home insurance, moving costs and a fund for first repairs come on top depending on the file.
