I suggest you try and buy your next condo/ townhouse, with the rent prices the way it is, you're better off just paying mortgage and be a home owner. The best way to find out if they allow pets in these complexes is to ask your agent if the HOA will allow it. I wish you the best of luck and if you are looking to buy a home of your own, let me know. I would love to help.
Check with a local Realtor and she/he should be able to find you a great location that will allow pets. If you use Craig's list......... make sure the landlord is reputable and actually the landlord prior to money exchange. There are a few scam artists lurking around and displaying on Craig's list.
