Hi, my name is Scott and I have been living here for about 3 years now. I lived in the Tampa Bay area of Florida for 20 years prior and the cost of living here is about the same across the board. The exceptions would be health insurance and vegetables. I am 61 and in Florida I was paying almost $900 per month for health insurance but here it is just $330 and includes dental. The problem is finding the right doctor and expect to wait 3 to 5 months for a specialist. Also, like many other things here, the hours of operation for doctors etc. seem to be merely a guideline or maybe even a best case scenario wish. Fruits and veggies are more expensive but other groceries are about the same. 1/2 gal milk: $3.08.
Another financial benefit is homeowners insurance. As long as no more than 30% of the home is made of something other than concrete, ie, wood, steel etc, insurance is about $700 per year for a $150,000 home and is not mandatory plus there is no real estate tax for a resident’s first home.
I live in the North-West corner of the island in the Isabela/Quebradillas area and home prices are similar to Florida as well.
So, all in all, if you could live comfortably in Florida on $3K/month then you should have no problem doing the same in Puerto Rico.
