It’s always a good idea to research the area before going ahead with buying a house in it. There are a number of elements you need to keep an eye out for, the importance you attach to each one will depend on your priorities, and who you ultimately decide to sell on to when you move on.
Key elements to look out for:
Schools
Transport links
Amenities (shops, supermarkets, pubs, etc)
Medical centres
New estate agents springing up in the area
