This really helps me understand how to analyze the deal. as for the data, I tried to get the most accurate but speculative information Ive found online. 

The team has institutional experience and would gather data, analyze financials, interview the management team of the tenant company, and then document and memorialize their findings into an institutional grade credit memo.  

The listing should be on the local MLS You can always check the "data source" noted on realtor.com to see what MLS' are used in a given area. b.

Often times you are only seeing a "view" or "report" of the information available on a listings, not every single data item available.

@Moly Yang - Not at all, I think you just need to run some numbers to ensure the house is profitable.

Organization and accuracy ensure a trouble free transaction. 

Where is a good place to research local demographic data for target locations, such as income growth, job growth, population growth, median rents and median income, as well as other important info? 

Reserves are key to ensuring that you can weather the storm of unplanned expenses during the hold period of your property.

My instinct is telling me I'm doing things wrong: that third party sites offer neither unique data, nor fresh data, and that I'm wasting my time browsing them.

There are different places you can run data to be able to get a better idea if this will work, but the property needs to be nice and also in a good area at the end of the day.
