I saw a listing in the Press Democrat today for a rental in the Coffee Park area. I would check the paper and the Press Democrat online. Also DeDe's rentals http://www.dedesrentals.com/ here. Good luck.
Craigslist is a good place to start and there are several rental agencies in town. If you have anyone to help you purchase a home drop me an email! Best, Terry Bell, Realtor, CPS Real Estate, Santa Rosa, CA
