NAI ReStore has been selected by Centro Properties Group to market for sale a 17-property shopping center portfolio. The portfolio includes more than 1.3 million s/f of GLA (gross leasable area) in community shopping centers and grocery-anchored centers in nine southeast and midwest states, and has an aggregate value in excess of $90 million.   "Centro chose NAI ReStore to market this portfolio because NAI has brokers in the local communities where these centers are located," said NAI ReStore president and CEO David Solomon.
