As you probably aware there are a lot of estate agents out there trying to get your money,
Inspection trips are a good idea but dont decide while you are there, use one for research thats all- to see what areas you like- then come home and do your homework to see if you believe everything they have told you.
Then go again on a holiday and see if you really like the area and look seriously at whats on offer (look round the different estate agents and speak to people who have bought there, are they happy with the company they used?
Then go back at the end of the summer season or winter time and negotiate yourself a bargain!!
