In today's competitive real estate market, how your property compares with other like homes will mean the difference in securing an offer.
Living day to day in a property, it's easy to overlook flaws and minor fix-it projects. Then the day comes when we want to move and these seemingly little projects become an overwhelming nuisance. Some homeowners feel that the new buyer 'is going to change everything anyway, let them pay for the improvements'.
You could decide to do this. However, by doing so you set yourself up to either, 1) receive a lowball offer 'because there is so much to do to fix up the place and that will cost us money' or you could miss out entirely on an offer to the turn-key listing down the street. (Turn-key means turn the key and you're done--it's move in ready.)
Note this interesting article that outlines some fixes that historically have proven to have tremendous return for your efforts, dollars and elbow grease.
