Latest figures from government's housing review
Mortgage debt in the Isle of Man stands at 16% of all property value, according to the latest government review of the housing market.
The figure was £1.7 billion, which is 30% down on its peak of £2.45 billion in December 2009.
Just over £100 million of net lending was repaid during 2016.
There was a 10% rise in the number of houses sold in December 2016 compared to the same month in 2015, but flat sales for the same months fell by a similar percentage.
