In St. Paul you can register your vacant building with the city. During the peak of the housing market crash and the great recession there were over 2000 registered vacant buildings in St. Paul and most of those were houses.
Today there are 645 registered vacant buildings in St. Paul and 586 of those are homes. I mention this because there are fewer than 300 homes for sale in our fair city at the moment. St. Paul appears to own at least 135 properties at least according to tax records. Apparently, some of these homes are going to be re-developed. Some of them were foreclosures.
This little house at 47 Douglas street has been on the vacant building list since the Fall of 2009 and has been owned by the City of St. Paul since 2010. I asked about it a few years back and was told that it needed a lot of work. I’ll bet one day it will be a vacant lot owned by the city rather than a vacant house.
