While I agree the rent by the room strategy can be great if you know how to manage it well, from a lending perspective, a lot of 30 year DSCR note buyers won't allow properties with individual room leases, so it could make refinancing more challenging. 

Depending on the construction, you have to do major upgrades on electric, plan for plumbing for apartments which may not be permitted in the area for the sewer or septic.

But my question is: how do you find a partner to work with?

This is unsightly and can attract pests. 

Try it once and see how long it takes then make the decision on how much your time is worth after.   

Did you ever find out anything?   

What were the lot rents and how many lots were occupied?

Since then, I always post a Facebook marketplace listing myself as a placeholder for my rental so that nobody else can do the same thing. 

Its completely dependent on when the last time the company gets a data update and how often. 

.: Thanks for the replies I totally understand you can not eliminate risk 100%I was just wondering if there was a safer way to handle this.
