The HUD-1 is the official accounting of all transaction costs and credits, including a to-the-penny figure for the funds you need to pay to close. Upon receipt of your loan documents, your escrow officer will prepare your HUD-1, a three or four page spreadsheet. You’ll sign an estimated HUD-1 but keep an eye out for the final version. It will come in the mail a few days after closing. Keep the final HUD-1 in a safe place—you’ll need it to prepare your tax return and third page includes a easy-to-read chart with key terms of your loan.
