Merc Real Estate opened for business in January 2014. CEO Mechlenne Douaihy had enjoyed a successful career in a large agency franchise lasting more than 12 years, however the possibility of opening her own business proved too strong a lure and Merc Real Estate was born. With an office in Castle Hill and a tight knit staff of passionate professionals, Mechlenne has set out to build not just one of the most successful agencies in the Hills District, but one of the most admired and respected real estate agency brands in Australia.
