Well as long as you're financially stable and can support living here, id say go for it. I'm still young and I tried two times to live a stable life in SD and unfortunately it looks like this December I'll be heading back to the states. Had a very good us remote job that decided to change their policy and not allow me to work outside the country. Now, I'm planning a last minute wedding this Friday and it's a very stressful situation. I'd say come to SD for couple months before you make your decision, because what may seem great at first can change real quick. Added, since you stated you lived here before, I am sure you know costs here pile up very quickly and can be just as expensive as the US, but as I don't know your financial situation, I can't really say how comfortable you will be. Good luck
