Under difficult circumstances, I was given the responsibility of selling my parent's property. This presented many logistical challenges. With Kerry's guidance, my family and I were able to first negotiate the legal titling of the property. Once our documentation was correctly aligned, we were next presented with the challenge of finding the ideal buyer for our unique property. This property combined both residential and commercial units. Several other properties in the area had been sitting unsold. Under the pressures of a harsh market, Kerry, through his perseverance and ability to create positive relationships, was able to locate the perfect buyer. I witnessed Kerry's outstanding skills as a negotiator and mentor to other real estate agents. The negotiation was long, involving multiple lawyers and paralegals. Through this daunting process, Kerry kept me up to date with the obstacles we faced. His knowledge, positive attitude, and tireless hard work was rewarded with the sale of the property. I thank Kerry Mantziounis for guiding my family through a difficult process and successfully fulfilling our goals. I wholeheartedly recommend Kerry as a real estate agent and business associate. Sincerely, Theo[read more]
