The city has razed about half a dozen houses so far this year. From what I understand, they were taken for non-payment of taxes by the owners after multiple attempts to collect and were considered too unsafe or run down to allow occupancy.
Given the desire to get more people to move to Carbonale, instead of demolishing them, why not offer them to people for $1 plus a stipend equal to the cost of demolition on the condition that they rehab the house and occupy it for a minimum amount of time. If no one accepts the offer, then demolish it. Maybe I missed them, but I saw no indication that those buildings were up for sale or demolition. maybe there were notices posted online but that involves someone actively going online and searching for notification. Putting a sign in the front yard at least catches the eye of people driving by. Lord knows I am not an expert in the field but it seems demolishing the building makes it much harder to infill the space.
