One thing that often gets overlooked is cracks. Cracks can mean a lot of things, and can make people anxious about the condition of the home. A house can look fresh and newly painted, but if cracks-even very small ones- are showing up in the floors, on the walls, around the edge of the bathtub, etc. an alarm will go off with potential buyers. They may not even mention it to their agent. They will just walk away making assumptions that may not be valid.
Go through your home and see it the way an outsider would look at it. You are used to the cracks, but others are not. Determine if there are structural issues that need to be addressed and disclosed. If not, start repairing these problem areas. Use care and good workmanship. It will pay off with your potential buyers.
