I have gotten mowers before to resale. You just have to look them over. If you have to invest in a lot of parts and time you aren't going to make any money. I guess I have found for myself if I am going to sell something its going to be in perfect working order before I sell it. There has been times I just spend too much on them which doesn't take long when you start buying belts and bearing and then engine parts. Then if you are going to sell them for good money you need the chassis to look nice with a good paint job. I find a person will spend just a little more money and buy a new mower before they will buy a used one. Unless maybe you plan on buying and selling junk.
