My husband is a hair dresser and has his own business.  

I have seen some become self storage, some workout gyms, some garden centers, some antique stores etc.My clients tend to buy retail centers with internet resistant tenants for mix like doctor, nail salon, hair salon, karate school, gym, restaurant,etc.The sky isn't falling in retail.

A little upfront cash usually calms them down and gets them moving away and out of your hair.

Got tired of all the cat hair so I mentioned to the renter that the cats have to go so I can start cleaning to start showing the house, so he sends them off, the next day my cousin says that he's seen 2 fleas, so I start realizing that I have a flea problem, tell the renter that I'm calling Orkin to get rid of the fleas, Orkin comes out and sprays, 2 weeks later and scores of vacuuming I still have the devils, I'm not sure if the Orkin stuff is killing them because the only time I see them dead is when I kill them, I'm getting bit every day, everyday I'm worried that I will transport a flea or the eggs to my house or another of my properties, so I stopped going to my properties, I stopped going to friends, refuse to share rides or give rides, have bombed my car 2 times already as a precaution, I'm probably full of pesticide by now! 

Any excess is the return on your investment plus you get all the equity appreciation;I am sure you and your girlfriend can figure out how to divvy up the other shared living expenses like groceries, cable, phone, hair shampoo, etc.The important thing is you both talk it all out and you can then document into some sort of formal agreement it if you want.

If you do things the old ways with call in bookings, in person key exchange, and physical keys you will create so much work you will pull your hair out.

All jokes aside target the grey-haired investors...they have probably forgotten more [horror] stories regarding tenants doing this, that and the other thing than either of us would care to experience! 

You would be splitting hairs between memphis Indy Jax etc. so find a team you like first. 

That second building on our land is a hair salon that my wife runs her business out of.

If you think the guy/gal qualifies, but they are bald or have facial hair, would you not rent to them?
