A prospective buyer probably won't appreciate the pipe held up by a can and wrapped in gauze. A jerry-rigged fix shows the next potential owner that you failed to take proper care of your home. Worst of all, it raises questions aboutwhat else might be a problem with the house. Don't be penny wise and pound foolish.
I often suggest a pre-listing inspection so a homeowner can see the property objectively. Yes, you must legally disclose anything you find but a pre-listing inspection can also give you peace of mind and the opportunity to fix whatever comes up before you go on the market.
If you are thinking about buying or selling in the Texas Hill Country give me a call and we can discuss your needs. In the end, you'll benefit when you leave it to a pro.
