Become the expert on first time home buyer programs like down payment assistance. Get to know the programs available at the CA Housing Finance Agency (
http://www.calhfa.ca.gov/homebuyer/programs/chdap.htm). The counties and other municipalities may also offer home buying incentives, so research those too. Contact the approved lenders and find out about the available programs (ask them about the Neighborhood Stabilization Program) and how they work with them. Then blog about them on your site and on Trulia using highly relevant long-tail keywords. Your phone will ring and ring often.
My blog is really stale with the last post on August 11 or so (I have to get over this writer's block), but still there's a link to it on page one of Google for "Georgia Down Payment Assistance" and other terms and I am still getting calls.
I'd recommend getting a free blog at Wordpress.com or Blogger.com.
You must know how to convert the calls into leads. I usually will ask at the outset if the prospect is working with an agent. If they are not, I tell them that my knowledge of these programs is how I reach prospects to make my living and ask if they will work with me. Upon agreement, I move on to the other steps that we all learned about (determining the right program and lender, agency stuff, understanding their wants and needs, etc., house hunting, etc.).
NAR's 2008 Buyer Profile was a free download at REALTOR.com a month or so ago. There's was tons of info about buyers and sellers in there. It might be worth a few sheets of paper to understand your market. Hope that helps. It isn't rocket science and the only real investment is your time IMHO.
