More importantly though I think, I have several friends I can lean on who are commercial developers who can help build out a pro forma to filter leads when they come in.Big picture, I'm wondering how you might recommend approaching commercial property owners with direct marketing??

You didn't mention if it was a single wide or double wide home and also if it is just blocked up or does it have some sort of permanent foundation?  

Then think of every mid west town and and southern town and realize that this gentrification is not happening anywhere but a few places and not nearly to the degree it is in Charleston or Portland Or. for that matter.I started in Charleston almost 18 months ago  and what I bought then in some instances the prices have doubled..

One can do both -  a double close or an assignment.

My other two homes in Arkansas have no impact on the overall picture at the moment since one is still for sale and the other is now renting out.What is your opinion? 

Sometimes the quickest way to double your money is to fold it in half and put it back in your pocket.
