How do I properly put together a professional repot and presentation? 

You need to join the MHU forum.You will find out this is a horrendously terrible deal.What is the lot rent and present monthly lot rent income.

However, all the numbers I run do not present with a positive cash flow.

The passive house building standards are active in Northern Europe, and at a recent NYPH presentation I heard that in the past 5 years the entire new construction industry in Belgium has switched to the passive house standard.

It's not necessary to be present when the inspector analyzes the property.

JMHO.A sophisticated way to profit if you truely believe this area is in the path of progress is to contact owners and offer to buy an option to buy at some present value for as many years as they'd agree to for a few $k.  

No time like present.

Then you present your case to the judge/magistrate and hope you win. 

Even though we hired contractors because we were not present we were the property getting the least attention with the slowest work.- Appreciation: Do the research.

I was presented with a potential deal by an investor friend.
