๐Ÿ’ก Understanding Mortgage Costs

Principal

The original loan amount, not including interest. With a down payment, the principal is reduced.

Total Interest

The total amount of interest paid over the life of the loan. Shorter terms mean less interest paid.

Total Cost

Principal + Total Interest = Total amount you'll pay for the home.
