If is new construction most developers DO NOT POST IN MLS, and a realtor would not be able supply you with sold per sq. ft. however work in concert with realtor & appraiser. All communities have certain deed restrictions on price of homes built/sold/sq. ft. Tax records would supply additional information if its sales were updated upon closing.

I don't have a realtor yet (I am just starting to interview them). However before I get too deep into the process with a realtor, wanted to see approximate prices to understand if I should even enter the market....

A local Realtor is your best source. DO you have one as your buyer agent? Presenting this sort of information to you is part of a buyer agent's job - and it should cost you nothing.
