As so many others have said, rural life is not like-town-life-but-in-a-prettier-setting. Whatever jobs you and your DH eventually decide to do, it really helps if you also have a certain extra resilience.
Obviously, it depends where you choose to live. As previous posters have also said, there's been a big move to accessible countryside recently, and also a lot of new developments around older villages. Houses in these places are not necessarily cheap. Nor are they in scenic areas, however remote.
Also, for many very rural areas, you and your family will have to think about:
No mobile signal
Poor/expensive broadband
No radio signal
No public transport or just one (school) bus a day; this can mean an hour's travel each way for children as young as five
No local shops or - more likely - a lovely, helpful local shop where fruit and veg can be almost on the point of going off when they first arrive from the wholesalers and where other, ordinary things are very expensive because small shops can't get bulk discounts.
Supermarkets - maybe a couple of hours away each way. With a much more limited range than in big towns
Expensive petrol
No supermarket deliveries
No fast food deliveries
No cafe culture; yes, there are a few cafes but most close in the winter and otherwise they're set up to cater for tourists
Wonderfully helpful local couriers, but still a delay if ordering things online.
Holidaymakers and badly-driven campervans - no good if you have a schedule to keep up with
Wild campers - some = OK; some = entitled filthy inconsiderate louts
Snow, black ice, fallen trees blocking roads
No mains gas; septic tanks; private water supplies
Electricity power cuts
A and E, dentist, hairdresser, optician, chemist maybe 50 miles away
Your children's best friends might live 20 miles on the opposite side of the school cachment area.
Not a great range of after-school activities available.
Drugs and alcohol a threat - if not always an actual problem - for teenagers. Accidents by teens driving first cars on difficult unlit roads ditto.
Fairly high Council Tax (low population/large area)
In many rural areas, it's proved exceptionally hard to recruit GPs
Community not guaranteed:
-Many local houses empty, either let out by the week or belonging to rich holidaymakers/weekenders.
-Threats of inappropriate development causing controversy
- Overbearing big landowners/tourist companies; divided local opinions. Some of your neighbours wil be employed by a landowner or tourism business and can't complain; others will welcome all kinds of development; others won't like to make a fuss. This can lead to big divisions.
- Division also between people who work on the land and with animals - and whose families have very often been there for generations - and incomers/ commuters etc. 'Old' locals will often be wonderfully kind and friendly and helpful to newcomers, but you won't automatically 'belong'.
If all this is for you and your family an adventure or a challenge, then fine. Go for it. As previous posters have also said, there are many absolutely wonderful compensations. I'm not being off-putting, just realistic. I live in an area where most of the above 'disadvantages' apply, and I love it.
