Take a drive into the community and look for the community bulletin board. Call those numbers on the 'FOR RENT" ads.
Be sure to actually chat with the owner of the park. Mobile home parks have such high monthly charges and these things are not easy to sell, so many owners simply hand the keys and signed title over to the park owner in lieu of further payments. You can start with the park behind 'Wings' on Ulmerton Road.
Who will rent to those with bad credit? Just about anyone.
