I have an apartment that is going to be a rental and I'm trying to fix it up the best I can on the cheap. I have 2 bedrooms and a living room that are hardwood floors but they are kind of beat. I'm not looking for miracles, just sand them down and put something on them to improve them. I actually hand sanded a spot last night that had a water stain just to see what would happen and it came out pretty easily. What am I looking at for cost to rent this machine and time or should I just hire somebody for these 3 rooms?
