You have a case of buyer’s remorse. Don’t worry, it is not fatal, but it may be contagious to your spouse. Buyer’s remorse happens to everyone who buys a house, no matter how many homes you have bought and sold before. It is that fear in the pit of your stomach that you have just made the biggest mistake of your life. The good news is that if you have done your homework in looking for a house, and if you have used the advice of real estate professionals, you probably have not made a mistake.
