find_nyc_property
ChatGPTFree. Finds New York City tax lots by address, e.g. "40 Water Street Manhattan". Returns each match's BBL for get_nyc_property. NYC only; for other US properties use the national property tools.
Overview
Hercules Real Estate Data is a property research tool for real estate investors. It answers questions about properties, owners and investors in the United States, using public records and licensed property data, in plain language inside ChatGPT. Use it to search property records nationwide, look up who owns a property, see who is behind an LLC, find NYC pre-foreclosures and distressed properties, and find active real estate investors and lenders in any market. It is built for investors, acquisitions teams, wholesalers, lenders and agents. What you can do - Property search and property records, anywhere in the United States: filter by city, county, zip code, property type, equity, absentee owners, vacant properties and more. - Owner lookup: the owner of record, owner type, mailing address, how long they have owned it, and whether the property is owner-occupied or absentee-owned. - Property details: estimated value and equity, mortgage and lender, last sale date, beds, baths, square footage and building details. - NYC pre-foreclosure and foreclosure data: lis pendens filings by borough, foreclosure stage, equity, filing age and recently added cases. - LLC owner lookup: find the officers, managers and registered agent behind an LLC or company that owns property, from public business filings. - Active investors: see who is buying in an area, including cash buyers, portfolio owners and corporate buyers, grouped by owner with recent purchase counts. - Investor and lender firm search: hard money lenders, private lenders, note buyers, fix-and-flip investors, real estate funds and wholesalers, with business phone numbers, business emails and websites. Before a large search runs, you see how many records match and get suggestions for narrowing it. Nothing runs until you confirm. What it does not do - It does not provide personal phone numbers or personal email addresses. - It covers properties in the United States only. - A Hercules account is required. Try asking - "Find absentee-owned single-family homes in Tampa with at least 40% equity." - "Show me NYC pre-foreclosures in Brooklyn added in the last 30 days." - "Who owns 123 Main Street in Austin, Texas?" - "Who is behind Lennar Homes, LLC in Florida?" - "Who is buying multifamily properties in Miami?" - "Find hard money lenders in Phoenix." Results are provided for research and may be incomplete or out of date. Verify before relying on them. See the privacy policy and terms for details.
Tools
get_credit_balance
ChatGPTShows the credit balance of the user's workspace, credits spent today, and recent charges. Free; never spends credits. Use it when the user asks about credits, or before a search that would cost more than the balance.
get_hercules_overview
ChatGPTFree, no sign-in. Describes Hercules: what it covers (every NYC tax lot, NYC pre-foreclosures, nationwide US property records, LLC owners and investors), every tool and whether it spends credits, plan and credit prices, and how to connect an account. Call it first when the user asks what Hercules can do or what it costs.
get_nyc_preforeclosure_detail
ChatGPTSpends 1 credit, unless this workspace already pulled the record, then free. Returns the full record for one NYC preforeclosure: case and index number, stage, lender, amounts owed and due, mortgage, owner of record and building facts. NYC preforeclosures only; take the id from search_nyc_preforeclosures. Tell the user it costs 1 credit before calling.
get_nyc_property
ChatGPTFree. Returns the public facts for one NYC lot (building, lot, units, year built, last sale) and the owner of record from the city lot file. Also says whether the full report is already unlocked for this workspace and what unlock_nyc_property_report and unlock_nyc_owner_contacts cost. When the report is already unlocked it is returned in full.
get_nyc_unit
ChatGPTFree. Reads one unit inside an NYC building: a condominium unit (its own tax lot) or a co-op apartment (shares, valued here by an estimate from recent sales in its line). Pass the building lot from find_nyc_property and the unit as the person wrote it, e.g. "14E", "Apt 1C" or "#PH-A". Use it whenever the person names a unit, apartment or penthouse; the building lot alone describes the whole building, not the unit.
get_property_detail
ChatGPTSpends 2 credits, unless this workspace pulled the same property in the last 7 days, then free. Returns the full record for one property from a national search: owners of record, building and lot, value and equity, open mortgages and lenders, foreclosure filings and last sale. Take property_id (it starts with "prop_") from run_national_property_search or run_active_investor_search. Tell the user it costs 2 credits and get their go-ahead before calling. For NYC preforeclosures use get_nyc_preforeclosure_detail instead.
quote_active_investor_search
ChatGPTFinds who is actively buying in an area: properties in a zip, city or county owned by investors, grouped by owner when run. By default it looks for owners of 2+ properties who bought in this area in the last 12 months. Options: minPurchasesLast12Months keeps owners who bought at least N properties in the last 12 months. That count covers the owner's whole portfolio, not only this area, so it is the closest available measure of 'bought N+ here'; boughtWithinMonths keeps it to owners who bought here recently. corporateOnly keeps companies and LLCs. cashInvestorOnly keeps properties bought with cash by an absentee investor. outOfStateOnly keeps owners who live in another state. Each property record costs credits, the same as a national property search. Never spends credits: it counts the matches and prices one batch. Always quote first. Then tell the user the credit cost, the batch size and their balance after. Records this workspace already pulled in the last 24 hours are free. For large searches, prefer a smaller batch (limit) or narrower filters, such as a zip instead of a county. One run returns at most 250 records; page with offset. Quotes expire after 10 minutes. Call run_active_investor_search with the quote_id only after the user agrees to the credit cost.
quote_investor_firm_search
ChatGPTUse to find real estate investor and lender firms in a state or city: hard-money lenders, private money lenders, note buyers, fix-and-flip investors, investment funds, cash home buyers and wholesalers. Returns firms with business phones, business emails, website and key people (name and title only). Free: this tool only returns a quote and never spends credits. The quote states the cost per firm returned; firms not found cost nothing. Tell the user the cost and ask. Only after the user agrees, call run_investor_firm_search with the quote_id. To find who is actively buying properties in an area, use quote_active_investor_search instead.
quote_llc_owner_lookup
ChatGPTUse to find who is behind an LLC or company, for example the LLC that owns a property: its officers or managers, registered agent and formation details from public business records. Free: this tool only returns a quote and never spends credits. The quote states the credit cost (charged only if the company is found) and what that state's public records show; some states list the company but not its officers. Tell the user the cost and that note, and ask. Only after the user agrees, call run_llc_owner_lookup with the quote_id. Pass the company's exact registered name and the state where it is registered.
quote_national_property_search
ChatGPTQuotes a search of national property data: any US property, including NYC properties that are not in preforeclosure. Filters: place (state plus zip, city or county), property type, beds, baths, value, equity, year built, distress flags (preforeclosure, foreclosure, auction, bank-owned, vacant, absentee owner, high equity, free and clear, inherited) and owner filters (company-owned, out-of-state owner, cash buyer, owners of N+ properties, last sale dates). Never spends credits: it counts the matches and prices one batch. Always quote first. Then tell the user the credit cost, the batch size and their balance after. Records this workspace already pulled in the last 24 hours are free. For large searches, prefer a smaller batch (limit) or narrower filters, such as a zip instead of a county. One run returns at most 250 records; page with offset. Quotes expire after 10 minutes. Call run_national_property_search with the quote_id only after the user agrees to the credit cost.

search_nyc_preforeclosures
ChatGPTSearches NYC properties in preforeclosure only: lis pendens foreclosure filings in Manhattan, Brooklyn, Queens, the Bronx and Staten Island. It does not cover other NYC properties. For any other property search, including non-distressed NYC properties or properties outside NYC, use the national property search tools. Filters: borough, foreclosure stage, equity, case age, recently added, market value and amount owed. Returns summary rows, newest first, up to 25 per call (default 10); page with offset. Never spends credits. The first 25 summary rows each day are free, and rows the workspace already pulled are free again.

unlock_nyc_property_report
