Yes! There are a lot of great first-time buyer loans available right now. With the government's intervention earlier this year and the new legislation that goes into effect in January, there are many more options for San Francisco first time buyers.
I work with a lot of San Francisco first time buyers and know that FHA, CAL-FHA, Acorn and many other programs WITHOUT the income limits now exist. It's very exciting for our local market because finally the programs can work for nice homes here in the City. (aka, the loan limits are much higher now...)
Rather than go into the minutiae here, I think your best bet is to email/talk with a reliable and experienced mortgage broker who really knows first time buyer options.
Here are the 2 folks I work with frequently here in San Francisco. Check them out and let me know how it goes!
1. Frank Sandoval, Pacific Bay Financial
2. Monica Di Perna, Guarantee Mortgage
Good luck! It's an awesome time to be a first time buyer.
