A couple of more things to consider
1. Learn a bit of the language, you may never learn Turkish or Arabic but a few choice words will make it clear that you care and respect the culture. For Spanish this place is very good.

2. PLEASE, if you have teenagers and you're planning on moving to a different country FIND OUT WHAT THE SCHOOL SYSTEM IS LIKE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!! Sorry to scream but if you knew the amount of people I've met that have moved the kids to Spain at 15 or 16 and not realised that in Spain, kids go to school until they're 18! The look of horror on the kids faces when they realize they need to stay in school for an extra two years.
3. If your kids are little, under 10, don't worry about the language, they will pick it up as soon as they go to school.
4. If you still live in the UK, use an insurance company in the UK to insure your property abroad. It's not expensive and if anything happens, you will be governed by UK laws, claims done by agents regulated by the SFA and claims paid out in sterling

5. Have realistic expectations, moving to a warmer climate will not solve all your problems and if you plan to rent your property to pay for the mortgage, forget it. You can count on renting your property around 20 weeks a year, and covering about half of your mortgage and cost. This is a conservative figure but better safe than sorry.
6. If moving or having a house abroad is your dream, it's up to you to make it happen, don't give up and good luck
