Frequently Asked Questions (FAQ)
Does this include Ontario land-transfer tax? No—add it separately when budgeting cash-to-close.
Is the CMHC premium refundable? No, but you can port the loan to a new property and keep the same premium.
Can I amortize beyond 25 years? Only if your down payment is 20% or more; insured loans cap at 25 years.
Are TD rates the lowest in Ontario? TD often matches or beats Big-5 posted rates; always compare with brokers.
