Hi David Clarke,
Before we bought I did lots of research on areas and I thought QSD was an agent, as I had a lot of correspondence from them. Correct me if I am wrong about them not being actual builders. Anyway, we decided after a few inspection visits that the Mar Menor area was right for us and have just come back after completing on our new home. I think you are right, there is a lot of competition out there and it is a buyers market definitely so shop around and be 100% certain it is the right place for you before you make a decision.
