A study reveals a $30,000 difference in 5% down payment savings across states, from $10,400 in Iowa to $42,000 in Hawaii. Affordability depends on balancing income with housing costs, taxes, and inventory. States like Maryland offer better balance, while New York, California, and Hawaii face high prices and limited inventory. First-time buyer programs and private mortgage insurance can reduce down payment needs. Maintaining good credit also lowers loan costs.
