The Wall Street Journal featured research from The Roebling Index - our real estate research and data platform - along with analysis of expiring 421-a tax abatements across New York City.
Our study identified as many as 4,800 condo, co-op and rental buildings, containing roughly 66,000 apartments, whose tax benefits expired or are scheduled to expire between fiscal years 2023 and 2030.
A separate review of more than 37,000 condo sales found that apartments on blocks nearing the end of their abatements appreciated 5.4 percentage points less than those on blocks where the benefit still had years remaining.
After more spreadsheets than we care to count, it was gratifying to see the work cited in the Journal - with a direct link for readers who want to explore the underlying research.
