I am in a unique position where my family is in the business (contracting, agents, mortgages).Typically I know doing business with family can be very difficult, but I am hoping to be very clear upfront on expectations and partnership- I have found that doing business with family only becomes an issue when you haven't been clear on the onset the joint expectations because those conversations are uncomfortable.Any suggestions on how to structure/document everything financially?

We look at already occupied buildings and value add projects which allow for cash flow at the onset of the purchase for the most part when the building is mostly occupied and just underperforming.

I'd focus on setting up a strong foundation that will allow for safe, smart investing in the future.

Once that glue sets up (gets clear) be CAREFUL on setting down the planks--once it touches, it STICKS. 

Do some research on setting up a LLC with a real estate attorney in order to put properties in at closing .

If you don't know how to properly evaluate a park on the onset, know where your ADD VALUE is in the park, have a TURNAROUND and OPERATIONAL PLAN in place moving forward and have an exit strategy in place, chances are you won't do as well as you think. 

It's been annoying, to say the least.The property manager has been VERY professional, and due to so many daily tasks I have traditionally speaking, lately I have been working on setting aside time to really focus on why the home is not cash flowing as projected currently and how to improve my booking rate significantly. 

Read my post on setting up cargo containers and parking.9.  

I currently live in Florence but have lived in Muscle Shoals and Sheffield in the past.

Florence, Tuscumbia, Muscle Shoals, and Sheffield are, in my opinion, an undiscovered nugget for REI.
