BP doesn't allow any form of marketing in the open forums, which includes your business or services.

There is so much free content out there that can teach you about guest services, software, vendor management, and so on. 

My thinking is that by renting to a residential care facility I can effectively utilize all the space, earn above market rent, and help provide a needed service, while avoiding tenant parking jams. 

Have you talked to any social service agencies about this yet?

In a situation where you were doing an arbitrage (renting it from the owner, then yourself re-renting it to someone else) your costs to renovate/fix it up while you're using it would be able to be capitalized and depreciated by you once your rental was in service (available for rent to others). 

-OOS investors rely on service providers like agents and PMs and think they're guaranteed an outcome instead of just paying a fee for a service.  

You are not paying for their services and won't cost you anything extra anyways. 

Also, thank you for your service!!

First all, thank you for your service and kudos for making that sacrifice to househack it's definitely paid off!  

Many banks securitize their loans (bundle them together) and sell the loans to Fannie Mae or Freddie Mac, while continuing to service the loans, that is collect your payment.
