Of course, there is a certain amount of stress involved with home showing and getting your house in top shape, but try to avoid all that stress if possible because there's a lot you can do that will produce the kind of effect you want on the buyer. If you overlook a few things in the process, the more experienced buyers will understand and not expect everything to be perfect. What you need to do is make an honest effort to get any problems in the home fixed and come clean about any issues about the home with the buyer.
Many walls tend to have signs that they were well used in that pictures, mirrors, and other items were hung on them. Tiny holes in the walls are often left unfilled, and the presence of those tiny holes can affect a prospective buyer's impression of the home and ultimately his or her decision to buy. There are buyers who'll just ignore those tiny imperfections, but there are also those who'll factor the holes in their decision. If the drywall in your home has worse damage such as holes or visible cracks, then that is worse. If there is damage on your drywall, have it repaired before showing your home. It shouldn't cost you a lot. For the nail holes, use spackle for filling them in. Once you're done filling the holes, apply a fresh coat of pain over the wall.
You can't tell for sure what kind of people will show up to look at your home, but there are some who have a curious nature. For instance, someone could come in and he'll be opening and closing all the windows in your house. All they're doing is checking for problems that they could have to pay for fixing, so you do that and make sure there are no issues with all your windows. Damaged screens should be replaced because they just look bad.
If any of the windows are hard to open, it could be that the tracks are dirty. You can simply clean the tracks and that should make opening and closing the windows easy. The windows will also easily open and close if you try to rub a rag with some oil in it up and down.
If a prospective buyer is looking at your house at night, turn on every light in your house. Any exterior lights should be working and of course turned on, as well. Lighting has magical effects on people, which is to say it is all positive, so you want everything in your home to have a positive effect on your potential buyer. Do you have sliding doors in your home? If you do, keep them open. Inspect the tracks and remove any debris you see in them. You want to open all the doors because it helps to make rooms look larger, as the light will also illuminate more space which is a desirable effect. The great thing is that there are lots of resources on home showing that you can refer to ensure that you find the right buyer for your home. And of course, your realtor is an expert in home showing, so don't hesitate to ask him or her for tips.
