My thought is to take a compiled list of property addresses saved in Excel and then run data scrape from Zillow and Redfin on each of those addresses, pulling the property details back into excel and into the appropriate table I have set up. 

@Don MillerThanks for sharing the details of your project! 

The more detailed info/numbers you can share, the better!

Did you have a clear detailed scope of work?

As @Troy Gandee mentioned use the tax estimator on the County website or call the assessor.

Can I walk into offices and leave a flyer for everyone in the office to read and set up zoom meetings with those people to go over the details further? 

Worth noting that most firms will do two types of studies (although they may be named differently) - detailed engineering and modeling.

Be sure that you are honest from the jump, your estimated rate are only as good as the info you give them.

The rental market is expected to stay flat or soft through 2025, then is estimated to start appreciating again once the new supply of multifamily housing reaches traditional occupancy levels.
