Guide to Buying with 15% Down

Putting 15% down on a home means you need $60,000 upfront on a $400,000 home. Here's what to consider:

  • You'll pay PMI. With less than 20% down, private mortgage insurance adds roughly $198/month to your costs. This drops off once you reach 20% equity.
  • Lower barrier to entry. Saving $60,000 is more achievable than the $80,000 needed for 20% down — you can buy sooner and start building equity.
  • Your loan amount is $340,000. A larger loan means more total interest over the life of the mortgage — $474,330 at 7% over 30 years.
  • Don't drain your savings. Keep 3-6 months of expenses in reserve after closing. The $60,000 down payment shouldn't leave you cash-strapped for repairs, moving costs, or emergencies.
  • Explore assistance programs. Many states and cities offer down payment grants or matched savings programs for first-time buyers — these can supplement your 15% down payment.
  • Factor in closing costs. Budget an additional 2-5% ($8,000$20,000) for closing costs on top of your $60,000 down payment.

Frequently Asked Questions — 15% Down Payment

Do I need PMI with 15% down?

Should I save more or buy now with 15% down?

15% is a reasonable middle ground. If saving to 20% would take years, the cost of waiting (rising prices, missed equity growth) may exceed the PMI savings.

Yes — most loan types allow gift funds for down payments. Conventional loans may require you to contribute some of your own funds if putting less than 20% down. FHA and VA loans allow 100% of the down payment to come from gifts. You'll need a gift letter from the donor.
