Excellent suggestions.

I am looking to purchase a parcel of land in Michigan and plan on using cash for the purchase.

I get texts/postcards/calls offering me cash for the house a lot, but I don’t want to sell the whole thing outright, I want to retain my ownership and investment and build a property empire with someone who wants to invest - and I’m totally okay with full involvement or silent partnership. 

The plan here is to have a local (RV Certified) tiny home builder do the marketing to attract buyers that want to buy their tiny homes (cash or 25 year financing) and live in this park, until there are 44 pads occupied by tenant-owned tiny homes, paying $750/mo lot rent, on 1 year leases.

I'm planning to buy a SFH in Huntsville in the next 2 months so I'm looking to understand more about the area.My goal is to buy in a B/C class neighborhood for a deal that is expected to be cash flow even.

A couple of year ago I paid off my rental with the cash out from my home refi (lower interest and saving $ for paying it early).

I suspect you could be cash-flow positive in 1-2 years and the property should appreciate during that time.If my assumptions are correct, holding onto it is the better option.

Now, it seems like the goal would be to keep that property in the long run, so you would want to Refi that in a few years when rates come down and you again can qualify for a more traditional mortgage, but there could be a path to getting around $100k and taking the next few years to focus on banking cash flow and possibly expanding.I know, it's a bit out of the box, but if we were just blue sky talking about a solution, it's possible. 

In his affidavit it has the correct legal description that matches my cash sale, but I am not sure if that is good enough.

If you can rent the property in peak season for 1% of asset value per week you will virtually always cash flow.
