Your settlement statements serves as your final accounting of all the costs associated with your home purchase. It is a standard form produced by the US Government Housing and Urban Development (HUD). You will want to save this statement for future reference and provide a copy to your tax accountant in the year you close your home.
Prior to getting a settlement statement your lender should have provided you with a good faith estimate on the cost of buying your home. I will also provide you my estimate. You can compare these good faith estimates with your final settlement statement. The numbers should be fairly close, although the original is an estimate only. If there is a significant discrepancy you will want to consult with your lender prior to closing.
Below is an excellent video produced by an out-of-state title company that explains the settlement statement. While there are a few differences in Oklahoma, for the most part the information is applicable here.
