The Danish mortgage market is really strange. In practice the people buying property issues bonds in the private bond market (although in most cases it does go through an issuing bank).

So if an investor has no other opportunity than 0% for their cash it's a "good place". Many banks in Europe has negative rates on deposits so it might be the better alternative for some.

But there are no banking in a traditional way involved here where they have a product and lend to 0%.
