I agree that there definitely can be benefits to having a RE license when investing, especially the quick access to MLS data.

I took a real estate course and passed the NJ state real estate test to become a Realtor so that I could have access to the MLS, be able to have access to houses I wanted to see, and not have to pay closing costs.  

I am currently using allied schools Exam Cram DVD and Exam practice tests.

I wonder... with something as powerful as this, do you find yourself no longer needing a realtor to get MLS data or comps?  

@Taylor Green I know my local MLS includes data about past transactions for any given property, so yes, a real estate agent is probably your best bet. 

As noted by @Sean Brooks your best bet is to have a discussion with the listing agent, state your position with empirical data (recent sales) and hope to get a call in a few months when the seller/agent check in with reality.   

I have been sitting on the sidelines for the past couple years, gathering data, exit strategies, markets, etc, and this website has been a big part of it all.

If your eviction data comes from a third party, then you have to comply with the FCRA.

I started to think about the impact on comparable analysis and how the inaccurate data might artificially increase values in my neighborhood as the price/ square foot was $20 more.

I once did a back of the envelope calculation on long term rates using empirical research and data on the relationship between the fed funds rate and the 10 year treasury.
