It is a scary thing, such a big move over a long distance and away from familiar things, gv.
this link gives you an indication of prices/areas.
There are very good schools at Methven, Madderty, Stanley, Forgandenny and Muthill.
Crieff is a larger town with lots of different shops, good health centers, activities and the people are nice. There are good schools there as well.
Muthill is a cracking little village with quite an eccentric population. Good school too. It is about 5 miles from Crieff and 14 from Perth.
Dunkeld/ Birnam is quaint but quite expensive. Posh little shops but has one of the best schools of all.
Bankfoot is sleepy, has 1 shop and a good school. And three pubs
Prices for rents average out about £600 a month for a three bedroomed house in the smaller villages/ towns. There are places for less (or much more)
Perth has cinema, swimming pool, plenty of parks, good shops etc and has a good hospital.
I know the area s really well so if you want to find anything out just holler.
Good luck.
