Unless you go out and spend a lot of money racking up credit card bills, or fail to pay your bills, I would think being prequalified would also mean preapproved. Some real estate agents won’t even show you a house unless you are prequalified. Be aware though, that some banks and mortgage companies preapprove people for amounts of money they aren’t really able to spend on a house. Back when I was looking for a house I knew exactly how much I was willing and able to pay per month. The bank preapproved me for a lot more than that, but I kept my head and bought the house I knew I could afford. I’ve known people that have said “but the bank said I’m preapproved for a 200,000 dollar house, so they should know if I can afford it or not.” Take into consideration escrow, you might want a new car someday, you might want to go on vacation, you might want to eat. Good luck!
