"Walter is a Rock Star agent. We couldn't have had a better negotiator representing our interests. His advise and guidance was spot on from the first meeting to the last signature on the closing papers. When the CovID pandemic restrictions hit he kept us informed, quickly addressed our concerns, and   provided the encouragement we needed to remain confident about our sale. He's definitely a hands-on person who literally lent a hand during our move out day. We can't thank him enough."
