The program allows first time homebuyers to obtain down payment assistance, however it is limited in terms of income (meaning you can only earn so much money), and there is also a limit on the selling price of the property.
The funding is also limited, so with all of the budget cutbacks I do not know what the current status may be. However, you can find out by calling 818-548-2060.
In exchange for the down payment assistance the city put a lien on the property. When the property is sold or re-financed the lien is paid off.
