I would suggest getting the contract put together with her understanding she cannot take possession until OCT 6th (or whenever day 91 is) 

She now works for other firms in the Houston area.Our short term goal is to start out with wholesaling to pay off some debt and build up our savings.

Depending on your available income and debt to income, you may not qualify for many of them. 

Although, ideally I think I'd retire any and all real-estate debt at that point, hold what I'very aquired, and do more fix and flip.Regarding campground/Tiny Home, island property is an entity all its own, with added layers of regulation, etc.  

What must the agent possess that will make you commit to that person for a long term business relationship.

I was single, debt-free, with plenty of time on my hands and just enough money to make my first purchase and grow from there.

If, when neither the legal title nor possession of the subject matter of the contract has been transferred, all or a material part of the subject matter is destroyed without fault of the purchaser or is taken by eminent domain, the vendor cannot enforce the contract and the purchaser is entitled to recover any portion of the price that the purchaser has paid. 2.  

of course income debt ratios have to be considered 

You should also understand unrelated business income especially unrelated debt financed income UDFI.

Also, I'm in rather dire financial straits to be looking at 35k down properties; While I don't have any debt, I'm not employed and don't have much of a nest egg.
