Per-unit housing funding, now for the EU

What could the EU learn from housing incentive design ideas in the US? Progress Ireland notes growing US interest in flexible infrastructure funding grants awarded on a per-housing-unit basis. US policymakers have had to overcome Census data challenges on actual annual housing production to develop per-unit funding titration in bipartisan proposals like the Build Now Act; if the EU has the right data infrastructure, then tying EU infrastructure funds for high-opportunity metros to housing production in those metros could help both the politics and the practices of pro-growth reform.
