Is it possible to live there year round if your retired?

Retired, thinking of moving to the Ukraine looking for up to date info on requirements. Is it possible to live there year round if your retired? Planning on traveling back to USA for a few months each year to visit grand kid and family. Just lookin for the real scoop on things

Have you ever been here before?

yes but a few years ago. I spent alot of time there visiting friends over a few extended vacations 4 to 6 weeks at a time. Mainly in the Dnepropetrovsk area but had the opportunity to get around and see a little of the rest of Ukraine.
