We recently bought a house in the province of Bologna and applied for residency. We discovered that because we took early retirement just over three years ago and do not yet receive a state pension or work we could not get form S1 to cover our health needs. This means that we have to get health insurance but this has not been straightforward. Please be aware if you are in this situation. The commune have been very particular and have vetted every policy we have tried. We are very glad that we did not sign or pay without consulting the commune, who eventually gave us a list of their requirements to show to insurance brokers. We have ended up paying just over €2000 for both of us from Assitalia, who liaised directly with the commune for us. This was our cheapest quote except for one company who tried hard to sell us a policy which was for travel insurance and covered our health everywhere except Italy. We don't expect any responses to this post but thought our experience would be useful to others in a similar position.
