Also worth mentioning that the "rules" vary area to area. Some areas agency fees a re the buyers problem - others the sellers and others (Valencia iirc) you split it. If you're good at haggling the agent WILL reduce his commission. The Spanish ime are by nature wary of "exclusive" agencies.

The magazine FOTOCHALETS is a good way to get a feel for prices - also browsing you'll see the multi agent properties - may also find a decent agent who'll offer you what you really want rather than what they have on offer and cant shift!

My advice is however - Under no circumstances buy/sell without using a "notario" (public notary). There are many rural properties built without proper permissions - some get sold as "private" sales. Recently some have hit the news here as upon change of ownership the law was enforced - ilegal properties demolished with no right to rebuild - and as it's private you have only recourse to the seller - who's disappeared.
