If it's a resident owned development why doesn't he just pursue a conventional loan from a bank that funds MH's?

I think that investing that time and money will motivate me to continue pursuing my goals and to not give up.  

I know short sale can take sometime because I would need the bank to approve my offer also and their agent (niece) is willing to show me the home before it goes on market and they are open to working on deal.Should I pursue this deal and what would be a good strategy for this?

I pursue a number of different strategies at any given time.  

In this case you'd either need to pay enough to pay off the mortgage--in other words, pay full price--or pursue a short sale.  

The property is across the street from the library , within 1-2 blocks radius of the post office , diner, pizzeria ,churches , dentists office as well as other small businesses , what other information do I need before pursuing this deal?

I would never recommend pursuing a property without seeing either a Rent Roll or P/L Statement.

I am absolutely 100% committed to pursuing Real Estate in some capacity or another for a very long time, I am incredibly intrigued by the "no ceiling" aspect of how far you can take this business and I thoroughly enjoy every facet of residential homes from construction to sales to ownership.

I guess part of the reason why I decided to pursue architecture is that my father worked in construction for many years and this line of work was something I felt familiar with.

It sounds like the eviction process should be pursued.
