Hi Linda
Lots of good advice from people on here who have lived / owned property in Spain for longer than us, but just to balance things up, here’s my view. We sold up (literally everything) a few years ago, moved here, bought a finca with a small cortijo and have never looked back. I am also lucky enough to have an Irish passport, and from what I understand your passport gives your husband the ability to do residency as an eu citizen on the old rules - I maybe wrong here as we did our residency way back and things change constantly. Get in touch with a good gestor (I recommend Salvador in Almeria) and talk through your situation and they will give you factual advice.
I work part time so pay social security which gives us both state health care. Your private healthcare will be an going cost forever, which you have to consider carefully.
We didn’t buy our finca as an investment, it’s our home - the only time falling house prices matter is if you want to sell in the future - houses here can be in the market for years and years.
Give yourself 6-12 months renting, see if you like it here, and if like us you love it, then go for it - I’ll never go and live back in the UK again!
Wishing you all the best ...
