A couple of twist
That house in the states may give you problems with residency requirements. I R S may give you a hard time since you have property in the states that you may be renting and as such Uncle Sam wants a piece of that action
Also you have property taxes on that property, and you may also may need to pay state taxes since you could be considered a resident of CT.
Having a home in the state may complicate act 20/22 application as you have to become a resident of PR.
WarnerW is right, if the money comes from the states, you pay Federal, if you get social security you pay Federal. If you make money in PR from a business, or job, or rental property, or anything else, you pay PR taxes.
Those with mixed incomes pay both, but because PR for taxation is another country, the US and PR give you credit for taxes payed to the other.
A good number of Expats that are retired only pay Federal and no state or PR tax.
Get a tax expert it is worth the money for the first and second year as you are not yet stable resident of one or the other and the root of your income changes.
As I have heard money in a Roth IRA or other post tax account has to be moved to a PR brokerage to take advantage of the low taxation. I could be wrong.
There is an act 20/22 group in Facebook that may help you more.
