I use mysmartmove.com for screening tenants for credit, criminal background. btw, I manage 6 units and work full-time, but I live on-site at my 4plex, and will shortly be passing all these activities to my trusted handyman.

Did you do a criminal check, eviction report, contact past employers?

Not criminally, but you could potentially be civilly liable for allowing a neighborhood nuisance.

I'll never forget the time I had a tenant threatening to sue me for something and while I was in the unit he said to me, "I'm gonna sue your a$$, I know rental law" while holding up a criminal law textbook.

-Put bold information in the ad about easy qualifying for the property ( but of course you want to screen with a criminal background, verify employment, credit, evictions, ect). 

But if somebody gave you a loan, its almost criminal.  

Any conveyances into the corporation like setting in your cars and houses would likely be reversed as fraudulent, and you could face serious criminal sanctions.

My #1 AP attorney got caught up in a case where another client was found criminally guilty and the CA AG has taken a personal interest in punishing.

Other thing I learned is the city is criminally prosecuting the seller for not working on the place it’s been on the market a while untouched.

You can insure against this.A partner/principal can be bonded against other risks, non-performance for any reason, like disability, criminal acts, bankruptcy, or just bad management, that may be expensive and not worth the arrangement, so you would have risks.IMO, knowing very successful builders and developers, about the only way to guarantee any promise is by pledging assets, other assets to attach in the event things don't work, and at a value sufficient to cover the obligation after the collateral is secured and sold.
