You can figure out their rental history from public records using beenverified.com and/or your local court websites.I usually just do the latter; If they don't have any rental judgments or a criminal record then that is usually a good sign and if they do then you might want to think twice.So what does beenverified state with regard to use of their data and compliance with the FCRA?

Here's a few links:http://www.newyorkfed.org/householdcredit/2014-q2/data/pdf/HHDC_2014Q2.pdf http://www.rcm.company/non-performing-notes/

I told him that would change my criteria and it would no longer be the list of data I'm looking for.  

The websites tend to be more accurate in more densely populated areas because there are more data points.

I will definitely explore building credit.

Always gather market data.

The building that is setting on the property was last used is some kind of computer data entry center.  

. - One thing that may be a possibility with your CPAs blessing would be to explore setting it up as a loan to you and after the fact contribute the property into an LLC.  

I can possibly make some recommendations based on what type of roof you want or maybe what type to building you haven so you can explored some different options. 

That way, you would have a concrete budget to consider as you explore purchasing a home.
