Hi from Moray...
If you want to buy a property up here, best look on the various Solicitor Property Centres - solicitors do the estate agency bit as well as the legal side.
There is a centre for Moray, one for NE - covers further east, and one for Highland.
See link here:
http://www.sspc.co.uk/centreThe 'big' land agents work up here - search for Strutt & Parker, Savills, CKD Galbraith, Bell Ingram - they operate estate agencies along side their estate management. Also the usual suspect - Right Move.
Good luck with the move. When we came up here from Hertfordshire, we found it easier to rent a place and search from here, much easier than the 650 mile trek up the A1 to Edinburgh and beyond.
The buying system works differently up here too - have read up on the 'offers over' system.
Please ask if you have any questions about the area.
Regards
Sue
