“Should I change my carpets before we sell our house?”
Good question. It depends on what I call the “Eww, Oh, Ooo Test.”
If your carpets are so torn, worn, stained, smelly, or of such an ugly color that a homebuyer would say “EWW!”, it could make your home hard to sell and cost you. So it would be smart to change the flooring.
If your carpets don’t look great but aren’t offensive and would elicit a neutral “Oh” response from a homebuyer, it may still be marginally profitable to change them, but not 100% necessary.
And of course, if they look and smell just fine, then there’s no need to do anything.
