Do not do anything expensive, such as remodeling. If possible, use savings to pay for any repairs and improvements – do not go charging up credit cards or obtaining new loans. Remember that part of selling a house is also preparing to buy your next home. You do not want to do anything that will affect your credit scores or hurt your ability to qualify for your next mortgage.
When looking at a house, prospective home buyers often do not really know what to do. So they play with things. They flick light switches. They open everything with a handle. They turn on all the faucets and flush all the toilets. Having nice shiny fixtures makes an impression.
All your sink fixtures should look shiny and new. If this cannot be accomplished by cleaning, buy new ones. If you don’t buy something fancy, this can be accomplished inexpensively. Make sure all the hot and cold water knobs are easy to turn and that the faucets do not leak. If they do, replace the washers.
It sounds like hard work, but it's pretty easy -- even for the inexperienced.
Check to make sure you have good water pressure and that there are no stains on any of the porcelain. If you have a difficult stain to remove, one trick is to hire a cleaning crew to go through and clean your home on a one-time basis. They seem to be wonderful at making stains go away.
