Hey Christine, great topic!
Because Puerto Rico is a common wealth of the United states, all of the same regulations and availabilities apply.
But, more importantly, not only can anyone on the globe, purchase properties in Puerto Rico ( You absolutely need a local Real Estate Broker-obv), but tax breaks, gov incentives and recent senate/ visa incentives, make puerto rico the most desirable place to purchase US property.
Number one on your check list when purchasing a property in Puerto Rico, as with anywhere else, is if you are a serious buyer
-Have representative counsel. If you have an attorney at home, have them recommend a local attorney for your documentation.
-Find a reputable Real Estate Broker. Do not make the assumption you can handle purchasing prop without one.
Hope this helps and continues a great forum topic
