Preparing to sell your house? You should have two separate to-do lists. In one, itemize the issues a good home inspector is likely to find. Those are matters you must address. In the second list, put down the minor improvements that are totally optional but can be extremely persuasive to a potential buyer. A buyer needs to be able to envision himself in your home, and there are dozens of modest upgrades you can make to help the buyer feel comfortable following in your footsteps. From clearing clutter to replacing bathroom fixtures, find out which simple, affordable fixes deserve attention before you put the place on the market.
