Frequently Asked Questions

How much down payment do I need to buy a house?

Minimum requirements vary by loan type: Conventional loans can go as low as 3% (first-time buyers) or 5%. FHA loans require 3.5% with a 620+ credit score or 10% with a 580–619 score. VA loans (veterans) and USDA loans (rural areas) offer 0% down for qualifying borrowers.

What is the ideal down payment amount?

20% is the traditional benchmark—it eliminates PMI and qualifies you for better rates. But a 20% down payment on a median $400,000 home is $80,000, which takes many buyers years to save. First-time buyer programs at 3–5% down with PMI can make homeownership accessible sooner.

What are down payment assistance programs?

DPA programs offer grants, forgivable loans, or low-interest loans to help buyers with down payment and closing costs. State Housing Finance Agencies (HFAs), local governments, and employers offer these programs. Income and purchase price limits apply, but many first-time buyers qualify.

Can I use gift funds for a down payment?

Yes. Conventional, FHA, and VA loans allow down payment gift funds from family members with documentation (a gift letter stating it is not a loan). Some conventional loans require the buyer to contribute a minimum amount (typically 5%) of their own funds if the down payment is below 20%.

Should I wait to save 20% or buy sooner with less?

The right answer depends on rent vs ownership costs and home price appreciation in your market. If home prices are rising faster than you can save, buying sooner may make sense even with PMI. If the market is flat and you can save quickly, waiting for 20% avoids PMI and gets better rates.

What is lenders mortgage insurance (LMI) vs PMI?

In the US, the term commonly used is PMI (Private Mortgage Insurance) for conventional loans. FHA loans require both an upfront mortgage insurance premium (1.75% of loan) and an annual MIP. PMI on conventional loans can be removed when equity reaches 20%, while FHA MIP may be permanent on newer loans.
