Otherwise, I would try to move-on and look at this as an important lesson learned about tenanting properties and potential pitfalls of undesirable renters.

All of that makes me wonder if it would be possible to write a contract that could possibly cover all of the potential pitfalls. 

Some pitfalls:1.

However to prevent getting overextended or other pitfalls from growing too fast, I am one to two months away from putting in a solid offer on a new deal.

Any pitfalls to avoid? 

I'm sure you'd be able to poke holes in my plan so by the end, I'll avoid some major pitfalls. 

So it seems like a lucrative thing to investigate.But if anyone would be willing to share their 35,000ft knowledge or main things to consider I'd be interested to hear your experience, pitfalls you've found, tips you wouldn't think of right away, and any additional things to factor in when analyzing a deal (like providing amenities like tables and chairs etc) beyond a typical rental property analysis I'd love hear whatever you're willing to share and start a discussion!

If I purchase 6 single family homes with a commercial loan, what are the pitfalls if I decide to sell one individual house while keeping the rest as rentals.

A good lender would let you know the pitfalls but in the past 6 yrs I’ve had more issues with FHA loans falling through and having to go Conventional anyway. 

I didn't consider the pitfalls of my idea.
