I used earlier versions of this book to save thousands of dollars by avoiding the need to hire a real estate agent. If you have ever held a garage sale or sold a car without hiring someone else to do it for you, why would you turn over 3% or 6% to a realtor to sell your house? It isn't rocket science!
This simple guide steps you through the whole process from the basic legal requirements to timing, pricing, negotiations and escrow. Plus, unlike earlier versions I used, this has a CD with the all forms you are likely to need (unless your city requires something in addition... be sure to check).
When I sold my last house ten years ago, I entered into a flat fee agreement with a realtor to get it listed on the MLS. I see from the book there are is now a site that will do this for $50 a month. Looking on the Internet, you'll find several such sites.
As the book points out, if you follow its advice and still feel uncomfortable, you can hire an agent or an attorney to look over the paperwork before closure. That is still going to be a lot less expensive than listing with an agent.
I'm in my sixties and have bought and sold several houses, mostly using predecessors of this book. Why flush money down the drain? Do it yourself and get it down right using For Sale by Owner in California by George Devine for Nolo Press.
