welcome peter/jacquie
you seem to have your feet on the ground and know what you are looking for,which is a good start.
Before coming do a lot of searching on the internet to get a feel for the prices and areas.Note a few down which catch your eye then do visits while you are over.
You sound as though you will be driving so travel round until you find the right area,when you are both
agreed on an area then spend lots of time around the area choosen while you are over and when you get home use the internet.
Dont buy on instinct decide then make more visits to be sure,do this at different times of the day so you can see the place at all times,night and day,busy and quiet.
Then if you are completely sure about the area and the property,start the haggling.
good luck hope you find what you are both looking for
