Many states, counties and cities provide low to moderate housing finance programs, down payment assistance programs, or programs tailored specifically for a first-time buyer. You should always check in the area in which you are looking to buy. The CHDAP program is one currently being offered throughout California.
CalHFA offers a subordinate loan program called CHDAP. It is also described as a “silent second”, meaning payments on this loan are deferred so you do not have to make a payment on this assistance until your home is sold, refinanced or paid in full. This helps to keep your monthly mortgage payment affordable. The CHDAP provides this deferred-payment junior loan – up to 3% of the purchase price, or appraised value, whichever is less, to be used for their down payment and/or closing costs.
