  • Our Story

    Reaction Realty is an independent brokerage that began servicing bank owned properties in 2007. It was involved in the management of distressed properties throughout the Inland Empire. The company managed properties through routine repair and service request, delivering monthly marketing reports, assisting its client’s in unlawful detainer actions against former borrowers/illegal tenants, and negotiating cash for key agreements. This unique background has allowed the company to thrive during the market meltdown and gain invaluable experience and insight in the management of properties in the area.

    The company has been involved in both selling & managing Real Estate Owned (REO) and investment properties since 2007. Reaction Realty currently works directly with US BANK, OCWEN, GOODMAN & DEAN, First Preston, & New Vista Asset Management, the latter of which, whom act as a third party servicer for Fannie Mae. In addition to providing high quality work for its clients, the company is designated as a small business minority enterprise by the Southern California Minority Business Development Council (SCMBDC). The objectives of Reaction Realty are to generate a profit, grow at a challenging and manageable rate, and to live up to the ethical codes set forth by the California’s Bureau of Real Estate (BRE).
