Buying a pre-tax deed auction property. Have a question

[Jason Palmer]

Hey guys, I was hoping to get some advice on a contract I have. I've approached an owner whose home is going to tax deed auction next month. They've agreed to sale to me and signed a contract, but would like to stay and rent from me. They can't afford to pay off the taxes, but do have enough income to pay a modest rent. My question is, once I take possession and have them sign a lease, should I need to evict them at a later date, will the courts treat it differently since they used to be the homeowner? They probably wouldn't have the wherewithal to go through a lengthy and expensive legal battle - barring assistance from Legal Aid - but I still wouldn't want to risk it. I'm in Florida, by the way.

Thanks in advance for the help.
