Fixed-Rate Mortgage

A fixed-rate mortgage sets the rate at closing and holds it for the whole term, most commonly thirty or fifteen years. The principal and interest portion of the payment is identical in the final month and the first, whatever happens to rates in between.

That predictability is the product. It transfers interest-rate risk to the lender and lets you plan around a housing cost that will not move, which is worth a great deal over a period long enough to include several rate cycles.

Your total payment can still rise, and this surprises many first-time owners. Property taxes and homeowners insurance are collected through escrow and are reassessed annually — the fixed part is the loan, not the bill.

Term length is the real lever. A fifteen-year loan carries a lower rate and costs dramatically less in total interest, but the payment is substantially higher; a thirty-year loan buys affordability and flexibility at a much greater lifetime cost. Taking the thirty and paying extra toward principal is a middle path that keeps the lower payment as a fallback.

Against an adjustable-rate mortgage, the fixed loan usually starts at a higher rate. You are paying that premium for the certainty — and, importantly, for the option to refinance if rates fall while being protected if they rise.
