ACRIS — the Automated City Register Information System — is New York City's official public record of property transactions. Every deed, mortgage, assignment and lien recorded against a NYC property since the mid-1960s lives in ACRIS, and it is all public.
ACRIS records the documents that transfer or encumber property. The most useful for research are deeds (who sold to whom, and for how much), mortgages (who lent against the property, and the loan amount), assignments (when a loan is sold to another lender) and liens and satisfactions (debts recorded against, or cleared from, a property).
Each document is tied to a property by its BBL and lists the parties, the recorded date, and — for financial documents — a dollar amount. Because recording a deed or mortgage is a legal requirement, ACRIS is remarkably complete.
ACRIS answers the questions that drive real estate decisions: When did the owner buy, and what did they pay? How much did they borrow, and is that loan coming due? Who is the lender? Has anyone filed a lien? Reading deeds and mortgages together lets you estimate a building's equity, spot owners who are over-leveraged, and identify which properties might be ripe for a sale or refinance.
The catch is that ACRIS is built for clerks, not analysts. Searching it one document at a time is slow, and ownership is usually hidden behind LLCs. Crezly aggregates ACRIS across the whole city so you can analyze it at portfolio scale.
Crezly pulls ACRIS deeds and mortgages live and joins them to ownership, debt estimates and recorded sales. You can browse recorded deeds and liens in the Data Suite, follow an owner's borrowing across their whole NYC portfolio on an owner page, and see the most active mortgage lenders by volume.
Owner names drawn from ACRIS and city permits are public record, so Crezly publishes ownership and estimated-debt summaries openly. Personal contact details are kept behind the paid plan.
What does ACRIS stand for?
ACRIS stands for the Automated City Register Information System, New York City's online database of recorded property documents.
Is ACRIS data public?
Yes. Deeds, mortgages, assignments and liens recorded in ACRIS are public record and free to search, though analyzing them at scale requires tools that aggregate the raw documents.
What can I find in ACRIS?
Deeds (sales and transfers), mortgages and the lenders behind them, loan assignments, and recorded liens — each tied to a property's BBL with parties, dates and dollar amounts.
Does ACRIS show who owns a building?
ACRIS shows the recorded grantee, which is often an LLC. Piercing the LLC to a person usually requires combining ACRIS with other public records such as HPD registrations.
