People Also Ask About Down Payments

What is the minimum down payment for a $400k house?

For a $400k house, minimum down payments vary by loan type: Conventional loans typically require 3-5% ($12,000-$20,000), FHA loans require 3.5% ($14,000), VA loans may offer 0% down, and USDA loans also offer 0% down in eligible rural areas. Use this calculator to determine exact amounts for your situation.

How does the down payment percentage affect my monthly mortgage?

A higher down payment percentage reduces your loan amount, which lowers your monthly mortgage payment. It can also help you avoid private mortgage insurance (PMI) if you put down 20% or more, potentially saving hundreds of dollars monthly.

Can I buy a house with less than 20% down payment?

Yes, many loan programs allow down payments as low as 3-3.5%. However, putting down less than 20% typically requires private mortgage insurance (PMI), which adds to your monthly payment until you reach 20% equity in the home.

What's better: larger down payment or lower interest rate?

Both are important, but a larger down payment reduces your loan amount permanently, while interest rates can be refinanced later. A 20% down payment also avoids PMI. Use this calculator to compare different scenarios and find the optimal balance for your financial situation.

For first-time home buyers, the key strategies are: 1) Explore first-time buyer programs with lower down payment requirements, 2) Save at least 3.5-5% for FHA or conventional loans, 3) Consider down payment assistance programs in your area, 4) Factor in closing costs (2-5% of home price), 5) Maintain emergency savings after purchase.

Absolutely! The calculator supports multiple loan types including Conventional (5-20% down), FHA (3.5% minimum), VA (0% down), USDA (0% down in eligible areas), and Jumbo loans (10-20% down). It can model various home buying scenarios such as first-time purchases, investment properties, luxury homes, and specific market situations. The visualization tools show how different down payment percentages impact your loan amount and overall financial commitment.
Private Mortgage Insurance (PMI) is typically required when your down payment is less than 20% of the home price. PMI protects the lender if you default on the loan and adds 0.5-1% of the loan amount to your annual costs. Once you reach 20% equity in the home (through payments or appreciation), you can usually request to remove PMI. A larger down payment helps avoid PMI entirely, saving you significant money over the life of your loan.
