Public beta: Affordable Forever is live for early use and feedback. Building dates and purchase-right screens are preservation signals, not automatic legal determinations; check the source and protection details on each page.
Research built for action

Find the pattern before it becomes a crisis.

Affordable Forever combines housing data, source documents and policy research to identify preservation questions early — then turns that work into tools tenants, organizers and policymakers can actually use.

Flagship research in active development

These are working research products, not static placeholders. Their live data layers surface preservation questions now while deeper document verification and analysis continue. Every report separates screening signals from verified legal facts and keeps its limitations visible.

The 30-Year Clock

New York City's LIHTC Preservation Pipeline

See the annual early-warning pipeline, properties and total units by screening year, and the operational windows that matter for preservation work: arrived/passed, next two years, next five years, and years six through ten. The next layer adds deeper ownership, protection and governing-document research.

The 4% Era

New York's Expanding Affordable Housing Engine — and the Case for Longer Affordability

Compare 4% and 9% LIHTC pathways, current New York affordability terms and the initial NYC credit-type enrichment — then ask the public-bargain question: why should durable affordability depend on which financing route a project used?

NYC LIHTC ownership, credit type & what we still don't know

Our first property-level enrichment covers 2,587 NYC LIHTC records. The headline: owner type remains unknown for 43.9% of the extract — a major preservation research gap — while 4%/9% history and other active federal subsidy signals begin to build the Protection Stack.

Research should be usable in more than one way

Research reportsLonger arguments with live data, methodology, emerging findings and concrete preservation questions.Data notesShort, updateable findings driven by the same property data powering the tools.District comparisonTranslate the research into Council, Assembly and Senate preservation intelligence and open the buildings behind the numbers.LIHTC explainedPlain-language answers to the questions tenants and organizers actually ask.Programs & protectionsCompare financing clocks and affordability clocks, and understand the layers that may continue when one program reaches a milestone.Methodology & sourcesSee what each dataset can prove, what it cannot prove, and how Affordable Forever separates signals from verified governing facts.

Publication standard

The goal is the discipline of a serious policy shop without sacrificing accessibility. A policymaker should trust the footnotes; a tenant should still understand the argument.

Executive summary firstThe question, the finding and the ask should be clear before page two.
Data + documentsAdministrative datasets identify patterns; controlling agreements verify building-level facts.
Limitations visibleWe say what a number means and what it does not mean.
Action attachedEvery major finding should point toward a preservation, organizing or policy response.

Research agenda

These projects build on one another. The Protection Stack and verified property layer make the later research stronger.
