Having a clean and fresh home is always a great idea, especially if you are frequently accepting guests inside. What do you think will be the reaction of your guests if they find your home dirty with some strange smell? It will be a major turn off for you. This is even worse if your guests accompany some of the potential buyers of your home.
You certainly love the idea of your family and friends having a visit. But, preparing your house may require tons of work. You will need to strip the beds, scrub the baths, and place a welcome mat out. That is all you may think of doing before they arrive. However, you can do better than that, which may even make your guests feel from going back soon.
