Over the years, MEI has developed a uniquely successful residential marketing approach, as a core competency, targeted to potential buyers and renters in urban mixed-income communities and those first-time buyers who do not believe they can afford to own a newly built or renovated residence. Using a unique combination of product design and pricing, non-traditional marketing, and relationship selling/leasing, MEI has helped thousands of families realize the dream of homeownership. MEI also utilizes this approach to successfully assist families in renting high-quality housing.
