What Is a Mortgage?
A mortgage is a home loan where the property is the collateral. The lender gives you money to buy the home, you live in it, and you repay over 15–30 years. Skip payments? The lender can foreclose and take the home.
Your upfront contribution — typically 3% to 20% of the purchase price.
The loan amount — what remains after your down payment.
The lender's fee — expressed as an annual percentage rate.
