On average, a down payment typically ranges from 3% to 20% of the home's purchase price. States with higher median home prices, such as California and New York, often require larger down payments. Conversely, states with more affordable housing, like West Virginia or Mississippi, may have lower average down payments. It's crucial to note that these figures can change, and individual circumstances, loan programs, and credit scores also influence down payment requirements. For the latest and most accurate information, consult a local real estate expert or mortgage lender.
