Top 5 Countries With The Lowest Mortgage Rates

During the last quarter of 2015, a couple from Denmark was paying interest on their mortgage at a negative rate of -0.0562%. That is to say they weren't paying the bank money, rather the bank was paying them DKK 249 (Danish krones) or $38.

However, that doesn't mean that getting a mortgage in Denmark will earn you money as in this case (an exception) that was originally reported the Wall Street Journal. In fact, the root of this phenomenon can be traced back to the couple's floating (e.g., variable) mortgage rate that had been taken out several years ago. In Europe, these floating rates are calculated based on the Euribor (Euro Interbank Offered Rate) to which each bank adds its own margin (1.5–2.0%).
