We were lucky enough to sell through an advert on this website.
The thng that we were told made it stand out was the realistic price, compared to those on with agents.
We were not greedy - we did not work out what we needed to sell for, for ourselves to cover costs - we just pitched the price considerably lower than others similar - at the time by 20% lower than the cheapest. The exchange rate was in our favour , and without fees we were lucky and did not make a loss on a 2 yr old build sold last year.
My husband did have to go to Spain to show our buyer round - the 1st person to reply to our advert ended up buying the house.
We had been on with agents for the previous 2 years without a sniff, so it can be done on your own.
