I have been informed that it is common practice in Tenerife for estate agents to offer conveyancing services for both the seller and purchaser in property transactions. This would never be allowed in the UK
Do Not under any circumstances allow this to happen! use an independant conveyancing service, perhaps the link provided above. To use the same is very bad practice and can come back and bite you at a later date.
I have known property to be sold with illegal outbuildings etc, especialy if the agent is a friend of the vendor, the exchange of a brown envelope is not unknown.
Not meaning to tar all Agents with the same brush, but it DOES happen!
