It's pulling from local public data,  so Zillow results can vary by location. 

Call the property tax authority and ask them if owner data is public record and then get a spreadsheet export of properties that meet your criteria.

I know many vets who like me drive truck, and pass random drug tests on a regular basis.

Then let them know that if the data does look similiar in 6 months and you have made improvements to the property you will be raising the rent a resonable amlunt but still providing them the best value in the area.

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.
