Our story
About National Realty Group
From a two-person office in Riverside to a full-service brokerage — serving Southern California families since 1991.
How the company grew
National Realty Group was founded in October 1991 by Jeff Maas. The company started as a two-person office and soon grew to a medium-sized one. One of the original agents left to form a new home development company — Steven Walker Homes, now a large national home builder.
South Fork Mortgage Company, Corp. was founded in April 1990 by the owner of a large home builder. Jeff Maas stepped in as its broker in September 1993, and with the help of Jeff Evens expanded the company. In July 1994 the owner of South Fork retired, and the two Jeffs purchased it. They kept growing it from there.
National Realty Group remained separate until Jeff Maas sold it to South Fork Mortgage in 1996, which let the owners expand the brokerage while its agents could offer mortgage services to their own clients. A branch office opened in San Bernardino that year and later moved to Redlands. An office opened in Temecula in 1998, and the company closed $45 million in real estate and loan transactions that year.
In 1999 Jeff Maas bought the company from Jeff Evens, becoming sole owner and broker, and the name changed to National One Mortgage Corp. The company outgrew its 3,000 square foot Riverside office and moved to roughly 6,000 square feet. It grew past 40 agents within a year, and eventually to nearly 13,000 square feet with more than 125 agents and 12 employees in Riverside alone.
In the summer of 2003 we opened an office in Temecula. Offices followed in Corona, Ontario, Moreno Valley, Hemet, Las Vegas, Norco, Rancho Cucamonga, Phoenix and Murrieta. The one-stop-shop model gave the home-buying public the service and convenience it actually wanted.
