Down payments and mortgage insurance

You don't always need 20% down to buy a home, but a smaller down payment usually means paying for mortgage insurance. Understanding the trade-off helps you decide how long to save.

The key ideas

The 20% rule
With a conventional loan, putting at least 20% down usually avoids private mortgage insurance (PMI). It is a cost-saving target, not a requirement.
What PMI does
PMI protects the lender, not you, if you stop paying. It is added to your monthly payment or paid in other ways your lender offers.
Removing PMI
Under the federal Homeowners Protection Act, you can ask to cancel PMI once your balance reaches 80% of the home's original value, and it generally ends automatically at 78% if you are current on payments.
FHA mortgage insurance
FHA loans have their own mortgage insurance premiums. Depending on your down payment, they can last for many years or the life of the loan, so ask your lender how long yours would apply.
Down payment assistance
Many states, cities and nonprofits offer grants or low-cost second loans for down payments. Check your state housing finance agency.

Questions to ask yourself

  • How much would PMI cost per month at different down payment amounts?
  • Would waiting a year to save more actually save money, given home prices and rent?
  • Do I still have an emergency fund after the down payment and closing costs?
