If you’re not using a PM (I’d suggest getting one.) then I wonder if there aren’t business that specialize in moving out tenants.

They are usually good with their trade, but poor with their communication and with their business practices. 

According to passive activity loss rules, every business is obligated to adhere to specific criteria, especially when it comes to short-term rentals.

You can do both (though I wouldn't attempt to file business taxes myself), or you can do the bookkeeping and hire out tax prep, or you can hire out both.

Are you a realtor looking to increase business?

They have to in an effort to make the business profitable. 

The initial training is a 12 week program where each new investor will be told to set up an infrastructure of a legal entity, business cards, phone numbers, web pages and miscellanea, to pretend to be a real estate investor, because all this, will not really make anybody a real estate investor.

I feel that if both parties understand the risks; if real estate investing is their business, if both parties are sophisticated and experienced investors, and both decide the risks are worth taking, then subject to can be a workable tactic.  

But an amazing business model. 

I did not know that most DSCR lenders don't prefer a business model aimed towards student renters.
