This is seriously the easiest one to sell to. Any three room house will do. If it has a hallway too all to the good. For the best results/profit try this:
Bathroom: Toilet and Sink. He doesn't care if there is a tub or shower
Bedroom: Just a bed
Kitchen: he doesn't want one so you can sell all the kitchen stuff if there is any
Living Room: He doesn't require one but if you do set one up for for nothing but a cheap sofa and coffee table.
Office: This is where he cares about quality. Go for the most expensive desk and chair. Add a safe, and any type of bookshelves. I used multiple up hanging shelves and he was happy with that.
