Hopefully you have a lease agreement stating all of this that you can reference in court.

I have a very small parking lot behind the building ( I have attached an image).

If the twin home that you are referring to are a duplex / townhouse type of set up, you will likely have to do 2 loans, 2 down payments etc.

I'm far from a professional, but I've played the game you're referring to a couple times.

I want to give up to a $1000 referral for anyone who refers someone to stay for 4+ months.

I think you are saying you have about 100k of equity to work with if you sell/exchange in which case I would suggest you look at MFR'S, either in close proximity to you as you referred to or even considering another market if necessary and just figure out those relationships you need in that other area the same way you would vet the turn key operations and resources.  

New multi-family seems to be a big trend in the valley right now, especially down Knik Goose Bay Road and the core area around South Wasilla (sometimes referred to the Gateway area).  

I am used to getting references before I do business with property managers. 

Additionally, there are other opportunities I refer to as fail safes which can include DST's and TICs both of which, assuming you align yourself with the correct person or company, will often provide a better rate of return than you can receive yourself.

As luck and humor would both have it, the duplexes were about 10 strides from each other and were exact mirror images of each other... just like my twin and I.
