I'm not a realtor, but before you bash me take a look at the comments from Realtors about the source of the article: http://realtormag.realtor.org/daily-news/2016/02/17/best-place-be-real-estate-agent From this link: "Does anyone at NAR check this info or do you just copy and paste it thinking that no one will notice that it simply doesn't pass the common sense test?

Whatever you do, do NOT buy off on the brokers flyer with data.

If you're going to wholesale, you need to have a knowledgeable real estate agent on your team or access to sufficient data to run your own comps.

Complete the course online and take the test.

You have good instincts.Step one of screening is to verify all data on your application is FACT. 

Means test the deal for higher interest rates, lower interest rates, deflation, inflation, higher cap rates, lower cap rates, easy credit, tight credit etc.  

MN also has some harsh repercussions for landlords if they should have returned a deposit, so I'd personally be nervous testing out in court if you can take the tenant's security deposit, even if you had a clear addendum.  

Zillow's historical data is pretty accurate.

Im not sure there is any data point you can look at to better understand a transitioning, or gentrifying neighborhood.  

Sorry Jeff, you'll have to puke all the data again =(But if you go through the same place they will know ya and have answers to a lot of the questions that pop up!
