The city took the teeth out of the vacant/blighted property tax after the first year so it isn’t as effective now. Also if the property is for sale you are exempt for I think 12 months. It has been painted/cleaned up recently so he could use those permits as an exemption as well. Thanks for calling it in though, hopefully the renewed pressure will help.
As for the house at the corner of 9th and T St., the owners have been working on it for about a decade and had major structural issues to contend with first. It is slow going to do that kind of rehab yourself as a homeowner. It would be nice for everyone if they were at the point of focusing on the outside, but they aren’t yet.
