How is a mixed-use building in Union County valued?
Usually on total net operating income from the apartments and the commercial space, divided by a cap rate that reflects both, then checked against comparable sales. Vacant storefronts, short commercial leases or rent-controlled units lower the value. AcreX has no published mixed-use cap rate for Union County and prices from your rent roll.
