Two alternatives:
Find an estate agent that charges less than 5%
Sell it privately. Stick a sign in the window with your number on, and be prepared to take a lot of stick from time-wasters, nosey neighbours, estate agents trying to list it, and every other kind of crackpot out there. You can list it on some web portals (some are free) but in my experience, the sign in the window is more effective - if you're prepared for all the cr4p that goes with it. Bear in mind that most of the calls will be Spanish speakers, and also remember that if you don't use an estate agent, you'll have to handle any negotiation yourself, plus work out how to deal with the legal side of things.
Good luck!
(one other alternative: just slap 5% on your asking price, then pick your estate agent!)
