Frequently Asked Questions

How much down payment do I need for a house?

While 20% avoids PMI, many programs allow 3-5% down. FHA requires 3.5%, VA and USDA loans offer 0% down for qualified buyers.

Is it better to put 20% down?

Putting 20% down eliminates PMI ($100-300/month), reduces your loan amount, and often gets you a better interest rate. However, it means more cash tied up in the home.

What is PMI and how much does it cost?

Private Mortgage Insurance costs 0.5-1.5% of the loan amount annually. On a $300,000 loan, that's $125-375/month until you reach 20% equity.
