I would live to live a month in Tuscany and month in Amalfi coast as local.

Are you an EU citizen?

You can't. It is as simple as that. Even if you were Italian from another place or city than then one you are moving to, there is no way to "live like a local" before you settle down in a new place, meet people etc.

Furthermore, you will be on vacation, not working, and a life of leisure is definitively not representative of how people living in a place go around an average day either.

So you can quash those anthropological zoo fantasies altogether. The sooner, the better so you can set up a guilt-free trip foregoing the local-pretense.

I am originally from Ukraine but live in USA now. European culture is close to me. I love Italy.. food, fashion...
I understand we can't live like locals but sooo many people move to Italy and they are happy.. just curious how lonely we are going to be in Italy. From where to start and how hard to make friends in Italy? We choice Italy because my husband's family from Italy. Italian people open and friendly.

Not wishing to put the cart in front of the horse... planning if you could actually retire to Italy will help you.

Is your husband an Italian citizen, or US? Or both. Can he claim citizenship through his father or grandfather? If so it will be much easier for him but may be difficult for you.

Above is the ranking of the best real estate websites in Italy.

These are not for short term vacation rentals, these are real estate websites for people wishing to buy or rent property.

We are Americans. My husband's grandfather immigrated from Italy.
I think for now it's will be easier for us live 6 months in Italy and 6 months in Florida. Italy has better quality of life... I mean... food.. history...architecture...weather.... more things to do and see. Its more healthier. It's my opinion.. I may wrong... I just think from where to start... get private tour from Tuscany to Amalfi coast... or rent place in Tuscany and Amalfi coast??? Should I check airbnb or home away?

Thank you for website. I will check it now

Unless you or your spouse are a citizen of the EU, you cannot stay in Italy longer than 90 days over a rolling 180 day period.

To emigrate definitively to Italy you must apply for a long term visa under the ELECTIVE RESIDENCY visa.

Requirements are ample financial means (steady proven large monthly income from pensions and investments, etc.) and a rental contract in place.

If and when you decide to move to Italy, the first step is to go to your local Italian Consulate. In the meantime start with a short vacation of up to 90 days max, to see if you like it.

If your husband grandfather was an Italian citizen at the time of your husband's birth, he may qualify for Italian citizenship.
Go to the website of your local Italian Consulate and search for ACQUISTO CITTADINANZA

Thank you Roberto. Your information very helpful. I also readed on internet... if you have property in Italy... you can apply for permanent residency and after 5 years you can get Italian passport and you can get dual citizenship??? May be I am wrong.. that way we can stay in Italy how long we would like

Nope.
For an Elective Residency long term visa there are several bureaucratic and expensive requirements to overcome, one of which is having a rental contract executed for the period in the name of all visa applicants. The visa must be renewed yearly.
You need to go to your local Italian Consulate and inquire, since I am not fully familiar with them as I'm a dual citizen so I can move to Italy any time I wish.
For foreign residents To acquire Italian citizenship they have to have resided in Italy for a full consecutive 10 year term before they can apply. The process takes up to two years from application to oath ceremony.

It's more complicated that I sought. Just afraid invest money to buy a dream home in Italy and after you will not able to visit. International living make sounds soo easy to relocate to Italy. Thank you.

Reality Shows, including those international house hunting shows, are not necessarily real. There are immigration laws to comply with, no matter where you go. They are not insurmountable laws, (although retiring to the US is nearly impossible for foreigners), but they are complex nevertheless.

It's hilarious to me that people think you can just go live in another country like it is an entitlement. As an American living in Austria, I can't tell you how challenging it is to renew my residency and work permits every year. As someone who works with refugees resettling to the US, I can say that gaining residency in the US is equally challenging. There are laws.

Retiring to US may be difficult also for US citizens. I know a good number of Americans that came to work in Italy in the eighties. Now they are retiring or retired, but no one of them can move back to USA as they cannot afford medical assistance that is much cheaper in Italy.

I also know several Americans that, meeting the visa requisites, have moved to Italy for their last years. The thing is not impossible, it is simply quite difficult. You do not only need to meet the requisites, you need to be a very determined person and getting fluent in Italian is absolutely necessary. The country has its troubles and life is not so easy as it seems to the occasional traveler. But IMHO it has two redeeming features, quality of food and relatively cheap medical assistance (who knows if will it last for long?) that make up for shortcomings in general organization, efficiency of services, etc.
