To make it easier for you, your realtor handed you a home showing to-do list, but you can hardly believe your eyes at how long the list is. You don't really need to do everything on that list if it isn't possible for you to do so. What you can do is concentrate on the most important ones. You may or may not heard of the concept called "curb appeal". This simply refers to your home exterior's attractiveness or ability to draw in a potential buyer.
For the interior, most people will expect your kitchen to look exemplary in some way. Although your house should be in good condition inside and outside, some areas you need to put a lot more care in than others.
In most homes, you'll find well-used walls -- walls where all sorts of things were hung, such as paintings, photos, and mirrors. From a buyer's perspective, those small holes look bad. The holes are tiny imperfections that some buyers might take issue with and some buyers might simply chalk up to the normal use of the house. If the drywall in your home has worse damage such as holes or visible cracks, then that is worse. Obviously, you should have any damage repaired and it will not cost much. 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 also need to make sure there aren't obvious stains or other damages on your driveway and garage floor. If there are any long or huge cracks on the driveway or garage floor, get them repaired as soon as possible. Just get some concrete that is of the ready-mix variety and fill in the cracks. This is extremely easy and quick to do. If there are oil stains on your driveway and garage floor, scrub them clean. Use a good oil stain remover, which you can get at any home improvement store.
Any time a home showing is in progress, make little to no contact at all with your guests. Obviously, you'll have to interact with buyers if you're the one showing them the house and your realtor isn't there. Try to be friendly without going overboard. Don't engage in any negotiation without your realtor unless, of course, you're selling your home without a realtor. Leave the negotiating to your realtor; he or she knows how to get the best price for your home. No matter how insistent the buyer gets about negotiating, be polite but firm; let them know that you'll pass their questions along to your realtor.
Your home's front exterior needs as much care as your interior when you're getting your home all prepared for a home showing. If you've got the budget, don't hesitate to spend money on making the front exterior look as great as it can be. Your front exterior is the first thing any potential buyer will see. You can give buyers a good first impression of your home right there even before they step through the door.
