NO JUMBLEDNESS
Every room in the business should scream “organized, neatness, and this business is under control”. The only things that should be out in the open is what is necessary to run the business. Everything else should be put away in storage, a cabinet, or a closet.
Lastly, everything within the business should be cleaned at the same level you would your home. You want any buyer to feel like they could see themselves working in your business environment. Dirty tile floors, dirty carpets, unpainted walls, dust anywhere, or even a nasty bathroom can turn off a buyer. Don’t take this lightly, it’s a cheap fix and not doing it could sour your buyer.
