I would search in your jurisdiction to find out that answer. Some local governments have some programs fort he first time home buyers. For instance; Washington DC offers $5000 subsidy to first time home owners.
the state of California did introduce a program California First Time Buyers program also referred to as CHDAP. http://www.calhfa.ca.gov/homebuyer/programs/chdap.htm
It is a good program you can utilize for down payment or closing costs if you do not have sufficient funds.
Would love to talk to you about it. If you are looking in East LA I have a house that would fit this program.
