It's definitely one way to do it, but you should be prepared for higher vacancy and you should make sure that the area has a good supply of the tenant base that you're looking for in order to get those higher rents.A better approach is likely phasing the increase in over 2-3 years, adding a little bit to the rent each year. 

Obviously we didn't try and charge them for paint and supplies, but when I did hours and hours of work for cat odor mitigation, I was not very pleased to charge them $0.00 for my work (of note: I ended up having to hire an odor mitigation company to fumigate the entire duplex).
