I personally lean towards the multifamily route because I have a girlfriend and a dog which isn't ideal for a room by room rental.

But when one of the parties is licensed by a governmental board of some sort, the board can subject the licensed individual to higher standards behavior, and they can do this largely at will and without the higher thresholds of most criminal laws.

If you don't ever set boundaries and say NO, they will continue to escalate the behavior. 

I am not tolerating this behavior and am going to Non-Renew and then if necessary evict.

I only know about the times where this was found out prior to closing, obviously I have no way to know about the times this shady behavior wasn't found out.Since you get a vote in who this tenant is, and it's retail, PSA that commercial lenders (especially the ones offering the best terms...) are starting to vet deals by how 'recession proof' the tenants are, even if they are currently paying on time.

But until someone provides evidence (via their primary research like I did) that central NC, with 1M in population is completely different from everywhere else as far as SDIRA investment behavior, I will assume the above is consistent with the rest of the country.

Most small dogs fall into the range of between 10-20lbs. 

Increase the rent more than usual,   just don't link it to the tenants behavior.   

For me it was all groovy with 8 people living in a 4 bedroom house with 4 dogs for a few years, as we were all friends.

Personally, I started out as a bird dog and wholesaler finding deals for other investors in single-family homes.
