As you can imagine, there is a lot of paperwork involved in buying a house. Your lender will arrange for a title company to handle all of the paperwork and make sure that the seller is the rightful owner of the house you are buying.
At closing, you will sign all of the paperwork required to complete the purchase, including your loan documents. It typically takes a couple of days for your loan to be funded after the paperwork is returned to the lender. Once the check is delivered to the seller, you are ready to move into your new home!
