Stupid idea probably, but here it is:
The housing market is something of a stable investment. Typically. People need somewhere to live. Population growth happens. Houses get more expensive.
In Iceland (in the capital region), the average sale price of a property in 2001 was 12mkr in 2001[0]. In 2015 the average was 37mkr. For first time buyers entering the market they now need an average 7mkr deposit in order to secure a 80:20 mortgage. A rather daunting feat compared with the 2.4mkr required in 2001.
(As a comparison, inflation (which wages at best track) would value that 12mkr property as 23mkr by 2015 - and that's with the 18% average of 2008 following the crash)
