But of course, the person living there would have to pay (equivalent to) $1000-$1500 / year on fees related to water, waste management, cleaning of chimney, etc. And you'd probably like to have the house insured.
And these weren't nice new houses. Mostly shacks built right after ww2, some not having been lived in for 10-15-20 years. Complete renovation projects.
What would happen is that some people from out of town would buy a house, plan to renovate it, but then mostly do nothing. Then many would forget to pay the municipality fees, often times for years. Eventually the unpaid bills would be sent to collection agency, and then a forced sale on behalf of the creditors. But now the houses were in even worse shape, so no one would purchase them at all.
Eventually they'd be torn down.
