Pet Fee in Chesapeake, VA

[Kenny Rains]

I've done a little research but I don't see much on pet fees. I'm strongly considering allowing pets as I have a vacant property and I believe this will allow me to rent it faster. I don't want large pets so I plan to restrict the weight to 20lbs. In addition to charging $50 more per month in rent I am going to assess a pet fee to account for any carpet cleaning/replacement once the tenant moves out. The property is in Chesapeake, VA and I am looking for some feedback on what an acceptable pet fee would be for the area. Thanks in advance.
