Hi Jocey - Without seeing it, it's impossible to say how much you would get. The market in Daly City is certainly improving, but without more info about your situation, I can't say absolutely you should sell or you shouldn't.
I have a lot of statistics on my blog and have been paying special attention to Daly City because of the direction it seems to be going: homes for sale has been declining regularly. Check out those statistics, if you like, by looking under the "San Mateo Real Estate" tab.
My suggestion is to find a Realtor through a friend or family member and get some personalized advice. If you don't know of anyone that way, you can do some research on agents via the internet.
