As an investor, I value an agent coming to me with deals based on their in depth knowledge of the real estate landscape, networking, connections, and additional information they might be privy to. 

Evaluating deals on this site will help you understand expenses, income, and financial statement.

Could be a national lender or a site that sells your info for solicitation. 

New roof, interior & exterior paint, finished additional living space What was the outcome?

I agree with @Jonathan Greene that the question is vague, so my advice will have to be as well.The short answer: MTRs are real estate, so just like all real estate, any place that can long-term-rent cash flow with increasing jobs/population can be a suitable site to purchase. 

My last one i requested a call so i could meet him at the site.  

I prefer an assignment @William Causey as it keeps me off the chain of title and any issue(s) that go with being in the chain, as well as any additional expenses related to a doublel close.

Another avenue would be to call your utility companies and ask about installing additional meters.

I used a LOC to build a 12 site RV park in a small town, opened it up and 1.5 mnths later, I'm full occupancy and servicing the debt (some of it at 8.75%) & cash flowing.

They're probably fine with you paying for additional marketing as long as they aren't cut out of the deal.
