The option that asks for the least cash to close is FHA, 3.5% down.

  • Cash to close = down payment plus 3% of the price in closing costs (example).
  • Minimum score: FHA requires 580 or higher for the minimum down payment (HUD Handbook 4000.1). * Fannie Mae requires 620 when a loan is underwritten by hand; its automated system has no fixed minimum.
  • The ITIN row is an example with a rate 1 percentage point higher: ITIN loans follow no federal rule and each lender sets its own down payment and rate. Nothing in this table promises an approval.
