Do I treat this as an abandoned property, or do I need to file an eviction just to be safe?

The rate is 3.74% so it's hard to beat that if he refinances now, with bad credit. 

sorry wording bad is this the house i helped you find  lol owner finance it to me at 7 percent lol

Hire an exterminator.And get rid of the bad tenants now.As far as animals, I require renters insurance, I don’t know the law in FL, but in WI if a tenants dong bites someone, and they don’t have renters insurance, the victim can come after the property owner

Bad press + Bad charma = No for MeEven though it is technically by the book so to speak, politics and public perception could turn a great deal in to a great nightmare.

Probably not but that's not a bad thing necessarily.

As a realtor I do not really like to identify neighborhoods as "good" and "bad" on public platforms but you're more than welcome to give me a call for an unfiltered description of each area. 

But I've bought about half of mine in the past 6 months from wholesalers with mostly good, one bad, experiences.

Not that bad honestly.

Usually if a tenant is interested but has a troubled past (bad credit, evictions..), they won't even fill out the application - so usually once I receive a completed application it is a tenant with a good track record.
