I finished by telling them that if I got one more complaint from either of them about this and it wasn't legitimate that I was going to blindly deny renewing both of their leases when it came to pass.

If the rent is legitimately $1100/mo or more I'd say that's a decent deal.

Is it legitimate?

Have the paperwork ready to prove it's all legitimately earned & taxed just in case.

The insurance company agreed this was a legitimate claim and will pay for the repairs. 

I just want the data to be as accurate as possible so the legitimate companies thrive and the predatory companies die.For instance, here's an anonymized review snippit.  

In the event an applicant is rejected and reports me for an FHA violation I can prove I didn't even know the person was a convict, etc.If an applicant makes it this far and then a background check turns over a criminal history I will have to manually see if this history conflicts with having a legitimate and substantial effect on the community (e.g. a sex offender in an MHP full of families with little children is a non-starter for me).

I had hoped there was some sort of strategy to make this a legitimate  way to get started investing? 

That's why I wanted to know if it is possible and legitimate to do since I haven't done this before. 

I wouldn't give him the time of day let alone $7,000 to take a property from someone who has won a legitimate auction.Tell him to get a job and pay his bills next time.
