With so many locals fleeing their island, Puerto Rico has some cheap ocean front places for well under $200,000. You could snag a foreclosure for even cheaper if you pay cash.
Here's an ocean front condo on the 18th floor (won't be flooded or blown down by the next hurricane) just outside of San Juan for $165,000, hoa $155/mo.
