Part 1 of 4

Why a seller cares

PMI is what a conventional buyer with under 20% down pays every month, and it is already in the payment they qualified for. For a seller it explains why a buyer with 5% down still closes on time.

A simple example

A buyer puts 10% down on your $300,000 home. Their lender adds about $110 a month in PMI until the loan reaches 80% of value.

PMI is the lender's insurance, paid by the buyer, and it is what makes small down payments possible.

Part 3 of 4

What people get wrong

That PMI protects the buyer. It protects the lender against the buyer's default; the buyer just pays for it.
