“Our hat is off to Green Energy Money (GEM) and SecurityNational Mortgage Company (SNMC). They helped us make our clients’ dream a reality. The homeowners wanted an energy-efficient, high-performance home, including a solar photovoltaic system and whole-house potable rainwater system. GEM’s unique appraisal and SecurityNational‘s loan underwriting process ensured the homeowners realized economic value for their investment, and competitive financing. A win for everyone! We look forward to a long and prosperous partnership with GEM and SNMC for our future sustainable construction projects.”
