Resources To Use When Analyzing a New Market For Multi-Family

[Andrew Doolittle]

I'm in need of some unbiased market research data that I can use to make educated recommendations to my primary client as to which market in the mid-west they should look towards investing in the multi-family sector. Specifically Kansas City MO, Tulsa OK, and Northwest Arkansas. Does anyone have good recommendations/techniques that they have used in the past to analyze a new market? 

I've considered reaching out to appraisers, top brokers, and other sources in the areas. However, before I invest my time and resources into the data hunt I hope to hear any success stories others have had researching new markets first.

Thanks for any and all feedback!
