1) House prices. When you look at what you can afford for your budget there is such a huge variation. The same amount may get you a one bedroom flat in central London or a six bed detached house in County Durham. If you have a job that is flexible then knowing what you can get for your money is a big factor.
2) Burglary Rates. Burglaries make up roughly 7% of all crimes in the UK and are much more prevalent in some areas than others.

3) What will your support network be like? If you are leaving friends and family then choosing somewhere where you already know someone may make the move easier. Having to make a whole new set of friends can be challenging so finding somewhere with a little familiarity could help you decide on where to move.
4) What local ammenities does the area you have chosen have? If you don't drive is there good public transport? What are the local schools and neighbourhoods like? Is there a nice park for children to play in? Visiting the area in advance can help you get a better feel for how your family will fit in and how it will fit with your lifestyle.
5) What kind of jobs are available in the area? Are you close enough to a big city if you have a corporate job? If you work in a specialist job then it may be worth researching where the best companies are based to increase your chances of finding the ideal position.
