Working with HUD and a non-profit church group, Cal Star Development was able to obtain properties at $.20 - $.25 on the dollar in order to create affordable housing called "The American Dream" program. Focused mainly on duplexes/four-plexes, approximately 70% of the time, they were able to select a responsible tenant currently in the property, clean up their credit and keep them in the home. The company created opportunities for first-time buyers from South Central LA to Riverside and San Bernardino Counties.
