Frequently Asked Questions
A down payment is the initial upfront cash contribution you make toward the purchase price of a home. Lenders require a down payment as a form of equity investment, which reduces the loan amount and aligns the buyer's interests with the property. It lowers the lender's risk of financial loss if you default on the mortgage.
The minimum down payment depends on the loan program. Conventional loans allow as little as 3% down for qualified first-time buyers. FHA loans require a minimum of 3.5% down. VA and USDA loans offer 0% down options for eligible military service members, veterans, and rural homebuyers. However, a down payment of less than 20% on conventional loans requires Private Mortgage Insurance (PMI).
If your down payment is less than 20% of the home price, your Loan-to-Value (LTV) ratio is greater than 80%. Lenders require Private Mortgage Insurance (PMI) to offset the risk of high-LTV lending. By making a down payment of 20% or more, you keep your LTV at 80% or below, which completely waives the monthly PMI fee, saving you thousands of dollars over the life of the loan.
Your down payment goes directly toward paying for the property, reducing your loan principal and building home equity. Closing costs are administrative and processing fees (such as title searches, escrow management, underwriting, appraisals, inspections) charged by the lender and third parties. Closing costs generally run between 2% and 5% of the purchase price and are paid in addition to the down payment.
A down payment is calculated as: Down Payment Amount = Purchase Price × Down Payment Percentage. For example, if you buy a home for $400,000 and choose a 10% down payment, your down payment amount is $40,000, and your financed loan amount is $360,000.
