I would check with a certified Appraisal company. They may give your resources for free, or for a fee ask nearby similar property owners themselves. And then coompile the data.
There are compaies that compile this data on a regular basis for many cities/areas.
Years ago I was a residential landlord supplying this sort of information for the company that did the yearly analys.Then as a Realtor, I studied appraisal, while working in a small Realty company that also did appraisals.
