Comparisons were selling for $185k. 

Pros:- Low cost of buy-in / not much needed in comparison to other areas due to affordability in purchase price- High-Cap Rates- High Cash Flows- Stable market / continuing to appreciate- Beautiful revitalization of the downtown- Influx of jobs, employment opportunities - Plenty of renters- New Amtrak service coming- Surrounding neighborhoods are sought after, solid schools, "home team" mentality in most of the towns where people want to stayFor the Cons:- I can't think of any OVERALL cons that couldn't be avoided in working with the right team.

If you're working with a tax pro, they should be able to run a comparison for you to show the differences.

Cost comparison will be negligible.

As far as your credit goes, you can apply to several lenders and have them pull your credit, the bureaus look at that as comparison shopping for mortgage rates and they will hit your credit, but for much shorter term.

You need to learn how to do your own Searched on Zillow every day and start with Land Values to be able to do your own Comparisons.

As a comparison, CraigsList gets an 8 or 9 from me. 

As long as you are frugal and complete your due diligence and a good portion of the leg work (as it seems you are doing), the overall costs of the development wouldn't be outrageous in comparison to a comparable existing park.  

@Julia Taylor, One of your big calculations needs to be a comparison of moving into a passive opportunity you can 1031 into and keeping the compounding effect working for you. 

Zillow is great for overall market trends, neighborhood comparisons, and estimated home values.
