The 9 worst housing markets around the world

Puerto Rico is "now the weakest housing market in our global house price survey, amidst continued economic woes, high unemployment, massive emigration, and a near-catastrophic national debt crisis and credit rating downgrades," the report said.

Home prices in Puerto Rico fell 9.59% year-over-year in the second quarter of 2017, after climbing by 3.26% in 2016.
