What is PMI? Private mortgage insurance for beginners

One of the first surprises for a low-down-payment buyer is a line item called PMI. It sounds like it protects you, and the name — private mortgage insurance — does nothing to correct that impression. In fact it protects the lender, and you pay for it. That is not a scam; it is the deal that lets you buy a home without saving up a full 20% first. Understanding PMI helps you decide whether to buy now or wait, and how to stop paying it as soon as you can.

What PMI actually is

Private mortgage insurance is a policy that reimburses your lender if you stop paying and they lose money foreclosing. Lenders require it on conventional loans when your down payment is under 20%, because a smaller down payment means they are lending a larger share of the home's value and taking more risk. PMI offsets that risk — for the lender. You get nothing back from it, but you get to buy the house with less cash.

What it costs

PMI is usually a small percentage of your loan amount per year, split across your monthly payments. The exact rate depends mostly on your credit score and how small your down payment is: weaker credit and a smaller down payment mean higher PMI. On a typical loan it commonly adds somewhere in the range of tens to a couple hundred dollars a month. Because rates and formulas change, ask your lender for the precise figure on your loan.

The good news: it is temporary

Unlike interest, PMI is not forever. On a conventional loan you build equity as you pay down the balance and as the home's value rises. Once your equity reaches certain thresholds, PMI can come off, and your payment drops for good.

1. 1
   Reach 20% equity, then ask

   When your loan balance drops to about 80% of the home's original value, you can usually request PMI cancellation in writing.

2. 2
   Automatic removal at 22%

   Lenders are generally required to drop PMI automatically once the balance reaches about 78% of the original value, as long as you are current.

3. 3
   Consider a new appraisal

   If your home's value rose a lot, an appraisal may show you hit the equity threshold sooner than the payoff schedule suggests.

Should you avoid PMI?

Not necessarily. Waiting years to save a full 20% down payment can cost more than PMI if home prices and rents keep rising in the meantime. For many buyers, paying PMI for a few years to get into a home sooner is a reasonable trade. Others prefer to put 20% down and skip it entirely. There is no universal right answer — it depends on your savings, the market, and your timeline. A lender or financial professional can help you compare the specific numbers.

The bottom line

PMI is insurance you buy for your lender because you put less than 20% down on a conventional loan. It typically adds a modest amount to your monthly payment, protects the lender if you default, and can be canceled once you reach roughly 20-22% equity. It is the price of buying sooner with less cash — sometimes worth it, sometimes not, always temporary on a conventional loan.
