An active HOME signal can point to an additional affordability agreement that needs its own governing-term research.

NYC LIHTC ownership, credit type — and what we still don't know.
A first enrichment of the public LIHTC preservation layer, built to answer a practical organizing question: once a building appears on the early-warning map, what basic facts help us decide what to research next?
The first finding is the missing information.
The current enrichment contains 2,587 New York City LIHTC property records. For 1,135 of them — 43.9% — owner type is still unknown in the administrative-data layer used for this prototype.
43.9% owner type unknown
That does not mean 43.9% of the buildings have suspicious owners. It means a preservation system that wants to intervene early still has basic ownership research to do for a very large share of the portfolio.

Owner-type signals
Owner type is useful for triage, not judgment. A nonprofit signal does not make a building automatically safe; a for-profit signal does not prove conversion intent. Unknown means the controlling entity still needs research.
4% and 9% LIHTC signals
The enrichment also separates properties where the underlying subsidy records identify 4% credits, 9% credits, both, or no subtype that we could normalize from this extract.
Do not read “unknown subtype” as a third kind of LIHTC. It means the current enrichment did not identify 4% or 9% cleanly enough from the source record. The underlying building can still be LIHTC.
Other active federal subsidy signals
A LIHTC milestone is not the whole affordability picture. The same NHPD All Subsidies extract identifies other active federal program signals for some properties.
Section 8 · 171 properties
Project-based rental assistance can materially change the preservation picture. The contract and renewal status still need verification.
HUD Insured · 53 properties
HUD-insured financing can provide another clue to the property's financing and regulatory history.
Public Housing · 37 properties
A public-housing signal indicates that the property cannot be understood through LIHTC alone.
Absence is not proof of no protection. “No other active federal subsidy identified” only describes this enrichment layer. Local HPD/HDC/HCR agreements, 421-a/Affordable New York, J-51/J-51R, 485-x, rent stabilization, Article XI, resyndication and other restrictions are not fully represented here.
What this data note can — and cannot — tell us
It can prioritize researchOwner type, credit type, federal overlap and timing can help organizers decide which unfamiliar buildings deserve a closer look first.
It cannot determine legal expirationThe NHPD warning date remains an early-warning/screening signal until the governing agreements and other protections are reviewed.
It should improve over timeThe enrichment is reproducible. When the underlying source changes, Affordable Forever can rebuild the files, compare counts and document the update.
