If you are focused on technical legal liability over something this small I think you are only hurting yourself. 

What I learned is that student housing doesn't operate like multi-family, even thought technically it is. 2 different animals.

Thanks,Joshua The 3rd room likely isn't technically a bedroom.

We never got any questions ever again after that one discussion.I don't want to get too technical (or risk scaring other Landlords away from RUBS) but either way, don't forget that you needn't implement RUBS based only on the no. of occupants. 

Once we made our offer, we discovered the zoning is R1-6 and it's technically supposed to be Single Family.

They now say that we need to do technical analysis to prove water is coming from their unit and not from any other unit. 

We partnered with Livly that does a lot of work with staffing and insurance company placements. 

We recently got 2 weeks of bookings for executives from a staffing company in our area.  

Their technical support does well at responding to any issues.

In your first example where you get a property under contract for $50k and then assign it to your company for $65k, I'm assuming that'd be a cash purchase so - while you technically could do that - it would serve no purpose and you'd have to pay an extra $15k at closing.
