Frequently asked questions
What is the minimum down payment on a $800,000 home?+
$55,000, which is 6.9% of the price. The rule is 5% on the first $500,000 plus 10% on the portion above it, so a flat 5% down is not allowed at this price. Insured mortgages are available up to $1.5 million since December 15, 2024.
How much is CMHC insurance on a $800,000 home with 10% down?+
$22,320. The loan before insurance is $720,000, the loan-to-value is 90.0%, and the premium at that tier is 3.1% of the loan. It is added to the mortgage, so the total mortgage becomes $742,320. In Ontario, Quebec and Saskatchewan the provincial sales tax on the premium ($1,786 in Ontario) is paid in cash at closing.
How do I avoid CMHC insurance on a $800,000 home?+
Put down 20%, which is $160,000. That takes the loan-to-value to 80% and no default insurance is required. Compared with 10% down, the extra $80,000 of down payment removes a $22,320 premium and cuts the monthly payment from $4,313 to $3,719 at 4.99% over 25 years.
What does a 30-year amortization cost on a $800,000 insured mortgage?+
An extra 0.20 percentage points of premium, so 3.3000000000000003% instead of 3.1% with 10% down: a premium of $23,760 rather than $22,320. The monthly payment drops from $4,313 to $3,965. Insured 30-year amortizations are limited to first-time buyers and buyers of new construction.
