Part 1 of 4

Why a seller cares

An interest-only loan on your home means the balance has not moved since you took it, so your payoff is the full original amount. It is rare on primary homes now and more common on investment property.

A simple example

You borrowed $250,000 interest-only five years ago. Your payoff at closing is still $250,000 plus the current month's interest.

Interest-only loan: a simple example
The loanBalance after five years
Interest-only$250,000; nothing was paid down
30-year fixed at the same rateAbout $234,000
15-year fixedAbout $185,000

Interest-only keeps the payment low by leaving the debt alone.

Part 3 of 4

What people get wrong

That an interest-only loan builds equity through payments. Only the home's value moves the equity; the payments never touch the balance.
