Finding market cap for St.Lucie county multifamily

[Jose Petitfrere]

Im doing some market research in the St.luice county, FL area and I know it's a small market, but I'm having trouble finding the market cap rates for class C multifamily property with 50-100 units. I've tried calling on a few brokers in that area to see if they would know and I haven't found anyone who knew let alone some who didn't know what a cap rate was, its a little disappointing but I won't stop unit I get it. by the way I know how to calculate a cap rate for a particular property(NOI/value) I'm particularly looking for the "Market cap"?
