The biggest benefit for me is that it would eliminate a good portion of income taxes from depreciating which is my main goal .

It's when you buy a property with the intention of you living in a portion of it while renting the rest out to tenants.

I am currently renting my primary residence, and subletting two bedrooms on Airbnb in order to cover a large portion of my living expenses.

In conditions such as those we face today, fulfilling redemption requests would require us to either substantially deplete vital cash reserves, or, even worse, potentially sell assets into a down market, likely at a price far below actual value.

 Commissions would be like to a realtor, or a human who was getting a portion based on a  service. 

But to be fair rentals are the smallest portion of anything we do.Where things like sealing and staining are concerned, a homeowner and products from box stores have no place and likely their knowledge is less than stellar when it comes to chemical compounds and one kind of acrylic vs another etc.

If so, what vital information do I need to have in that CRM?

If so, their interests in the house would have absolutely been settled and documented in the divorce decree, as well as a vital portion of the "You can have the house"  conversation....    

My landlord has sublet a portion (upstairs) for another person.

Pay them back the remaining portion of deposit and be happy they left quickly.
