Janice, I sympathise with your situation, trying to please your husband and provide a good life for your children. We have friends who had to return to the UK in order to work (both English) because they couldn't afford to stay without working, they already have a home here and would love to return permanently.
You really must think your finances through very carefully before making any move. From your previous post it seems you have a mortgage on your UK house, so first, if you sell it will there be enough capital left after settling the mortgage to give you a decent income from bank interest here? And will you be able to keep that capital intact in case you need to return and start buying another house? If not, then I would rent out the UK property and rent in Turkey. I'd rent in Turkey anyway rather than buying.
I don't know what kind of work your husband is qualified to do, so can't comment on his job prospects, but unemployment is also high in Turkey, and as others have said there is no social security to fall back on. As you obviously know, work in the resorts is seasonal, what will you do in the winter months?
I don't want to put a damper on your plans but with 2 young children you really do need to think it all through very carefully. I wish you the very best of luck with whatever you eventually decide.
