What is a Down Payment?

A down payment is the portion of the home price you pay upfront in cash. It reduces your loan amount and can lower your monthly payment and interest cost. Conventional loans often require 5–20%; 20% or more typically avoids Private Mortgage Insurance (PMI). FHA loans allow as little as 3.5%.

PMI and Closing Costs

PMI (Private Mortgage Insurance)

Required when you put less than 20% down. It protects the lender and typically costs 0.5–1% of the loan amount per year until you reach 20% equity.
