Andy and Jenny, there will be many people who have moved happily to Spain, and also many who’s move unhappy due to a lot of unregulated corruption in Spain’s property business.
Do not trust the larger ‘in your face advertising’ estate agents who will charge you up to 30% more than the property is worth, don’t trust their recommended lawyers, and don’t part with any deposit unless you have a ‘cooling off’ period of at least a week, preferably 2 weeks to consider things with a full refund due if requested.
Don’t get involved with stage payments on new build, make sure a site has planning permission etc.
Buy from a smaller agent if possible or privately, it’s a ‘buyers’ market.
Check who the rogues are on previous pages here, like Awful Estates, who promise much and deliver little.
