When you are thinking of buying a home, it is NOT the time to make a big purchase or make any other changes in your credit history. You need to show the lender that you are not a risk, that you have the money to buy the home and that it is YOUR money, not borrowed.
Lenders will want bank statements, paystubs, and letters proving that you have the money to buy the house. We want you to buy a house that you can actually afford, and still be able to pay the bills. I do not want you to live a life where you can’t afford to go out to have some fun every now and then just because you bought too big of a house!
In preparing to buy a house, just relax and stick within your budget, do not go out and buy big ticket items. If you need to buy furniture for the home, even that should wait until after closing.
