We also have a wood stove going, so that skews data as well.As to how landlords recovering costs / profiting from tenants who benefit from solar, I have no idea. 

Neighborhood Scout, City Data are two good sources to learn about neighborhoods 

Due diligence tracks our progress and identifies any red flags pre-purchase; Borrower Management to track the data relating to the borrower/collateral documents/property; and Legal to track/monitor where we are at with demand letters, trustee sales, etc. 

One more thing - forgot to mention that the Bronx is predicted to have the largest population growth of all of the boroughs: http://www1.nyc.gov/assets/planning/download/pdf/data-maps/nyc-population/projections_report_2010_2040.pdf

@Brian Simmons - For an appraisal on a refi, they'll generally lean into the historical operations as their primary data points with support from comps on the income and expense side. 

From this data, you can utilize a website bestplaces.net that will give you a breakdown of the percentage of homes that sold, in various price ranges, for a given zip code.

People think working directly with a lender is a good idea, they just haven't met a good mortgage broker to find them the best deal.

@bobjones- ironically I met a guy today in Virginia who said his other business was picking up mobile homes on parks in the condition you described.

Most Tenants and Owners are great and by far are rockstars but every now and then it amazes me that we'll get an owner that hires us for our experience and expertise and then tries to step in and "co-manage" or want things a certain way aside from our system... we call these time wasters and quickly say 'no thank you'... we have too many GOOD owners and tenants we have to focus on and important things like running a reputable business and ensuring properties are taken cared of for this -- based on data and experience... not opinion.

Its potentially all there but its missing the rent roll data, or maybe its being built out little by little.
