A typical portfolio is plus or minus 700 doors.

We personally own 19 doors in a garden style building and 3 MF duplexes in and around St Joe and we do not have issues with tenancy rates and remain cash flow positive. 

When I tried to collect the rent for the last month she wouldn't answer the phone or the door for a couple weeks.

They sent me cabinets that were in different boxes, different construction, door sizes were off a half an inch, a pinstripe was a different color, they couldn't fulfill the order with the cabinets I ordered so they gave me different cabinets and said that they would work?

Even with raised rents its hard to do $200 a door. 

I'm currently working to partner with the larger property management companies like Greystar, and Costar to ask them to modify their anti-short term rental policies, in short term friendly cities like Scottsdale.

For the price I could have probably picked up 6 doors or more in Memphis or another appreciating market in the south east but out of state was just too big of a leap for my first purchase and I wanted to A. stop paying rent and B. be able to leverage air BnB for more cash on all of my travel in a way I could not with my previous rental due to lease restrictions.  

If that happens, I then would then stick the letter between the doors.

He says, that over the last 10 years, he replaced ceiling fans, and doors (all UN-authorized and news to me) so that should be considered rent money.

A larger house with a better commute to replace your current home isn't necessarily bad - and the finances you shared make it seem like an easy upgrade.
