It has two run modes. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md. ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run. For examples already wired to this Actor's own input schema, see the [API](#api) section below. Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`). # README [![Baltimore City MD Tax Lien Certificates: Owners & Amounts](https://scrapers.lat/banners/baltimore-city-md-tax-lien-certificates.png)](https://console.apify.com/actors/eMNOElhNQTcMOoksF/input) ## Baltimore City MD Tax Lien Certificates: Owners & Amounts Search the City of Baltimore tax lien certificate sale list and get the owner of record, property address, block and lot, sale year, the published lien, interest, legal-fee, miscellaneous and total amounts, assessed value and redemption detail as flat rows. This is a dedicated Baltimore City tax-sale source. Here is one real record from this actor. `source`, `source_page` are left out of this example and included in your dataset. ```json { "record_id": "BALT-2019-287-6466-035", "state": "MD", "jurisdiction": "Baltimore City", "lien_type": "tax_lien_certificate", "lien_authority": "Baltimore City, Maryland", "tax_sale_year": "2019", "bidding_number": 287, "block": "6466", "lot": "035", "property_address": "0903 S EATON ST", "owner_name": "MERCHANT HILL, LLC", "occupancy_flag": "N", "land_use_code": "R", "council_district": "01", "zoning_district": "R-8", "liens_usd": 9000000, "interest_usd": 0, "legal_fees_usd": 0, "miscellaneous_usd": 0, "total_amount_usd": 9000000, "assessed_value_usd": 770433, "redemption_date": "2019-05-13", "redemption_name": null, "certificate_status": "void", "status_note": "-------VOID", "is_redeemed": false, "latitude": 39.28, "longitude": -76.56, "source_record_id": 3344, "observed_at": "2026-10-31T21:16:45.722Z" } ``` **[Input](https://apify.com/lienintel/baltimore-city-md-tax-lien-certificates/input-schema) | [Output](https://apify.com/lienintel/baltimore-city-md-tax-lien-certificates/output-schema) | [Pricing](https://apify.com/lienintel/baltimore-city-md-tax-lien-certificates/pricing)** ![Coverage](https://img.shields.io/badge/Coverage-Baltimore%20City%2C%20Maryland-blue) ![Output](https://img.shields.io/badge/Output-JSON%20%7C%20CSV%20%7C%20Excel-orange) ![Billing](https://img.shields.io/badge/Billing-Pay%20per%20result-brightgreen) ### Table of contents - [What you get](#what-you-get) - [Input and filters](#input-and-filters) - [Use cases](#use-cases) - [Coverage and freshness](#coverage-and-freshness) - [Pricing](#pricing) - [Comparison with other Apify actors](#comparison-with-other-apify-actors) - [Related LienIntel actors](#related-lienintel-actors) - [FAQ](#faq) - [Run it through the Apify API](#run-it-through-the-apify-api) ### What you get - **The owner of record.** The name Baltimore City publishes against each certificate, so a lead arrives with a party, not just a parcel number. - **The property.** Street address, block, lot, council district, zoning district, land use code and the published latitude and longitude. - **The money.** Lien amount, interest, legal fees, miscellaneous charges, total amount and assessed value, each as its own numeric USD field. - **Redemption status.** Redemption date and redeeming party when the city publishes one, plus a derived `certificate_status` of `open`, `redeemed` or `void` and a boolean `is_redeemed` flag. Use it to separate certificates still outstanding from those already paid off. - **Honest handling of city notes.** Baltimore City sometimes writes an administrative note such as `VOID` or `BILLS PAID/TS NOT ON PREV` in the redemption field. Those notes are returned in `status_note` and are never presented as a redeeming party. Void rows are excluded by default because their published total can be a placeholder. - **Sale context.** Tax sale year and bidding number, so a certificate can be tied back to the sale it came from. - **A stable `record_id`** built from the sale year, bidding number, block and lot, and one flat record per certificate row. Each record can carry these 34 fields. A field the source does not publish for a record comes back as `null`. | Field | Type | Description | |---|---|---| | `source` | string | Baltimore City Tax Lien Certificate Sale Properties | | `source_page` | string | Public reference page for the source list | | `state` | string | MD | | `jurisdiction` | string | Baltimore City | | `lien_type` | string | Normalized lien type, tax_lien_certificate | | `lien_authority` | string | Taxing authority that offered the certificate, Baltimore City, Maryland | | `record_id` | string | Stable record key built from the sale year, bidding number, block and lot | | `tax_sale_year` | string | Tax sale year the certificate was offered, 2019 through 2023 | | `bidding_number` | integer | Bidding number published for the certificate in that sale year | | `block` | string | Baltimore City block number | | `lot` | string | Baltimore City lot number | | `property_address` | string | Property address published for the certificate | | `owner_name` | string | Owner of record published for the property | | `occupancy_flag` | string | Occupancy flag published by the city, D, H or N, kept as published | | `land_use_code` | string | Land use code published by the city | | `council_district` | string | Baltimore City council district, 01 through 14 | | `zoning_district` | string | Zoning district published for the property | | `liens_usd` | integer | Lien amount published for the certificate, in US dollars | | `interest_usd` | integer | Interest amount published for the certificate, in US dollars | | `legal_fees_usd` | integer | Legal fees published for the certificate, in US dollars | | `miscellaneous_usd` | integer | Miscellaneous charges published for the certificate, in US dollars | | `total_amount_usd` | integer | Total amount published for the certificate, in US dollars | | `assessed_value_usd` | integer | Assessed value published for the property, in US dollars | | `redemption_date` | string | Redemption date in YYYY-MM-DD form when the certificate was redeemed | | `redemption_name` | string | Redeeming party published for the certificate; null when the city wrote an administrative note instead | | `certificate_status` | string | Derived certificate state: open, redeemed or void | | `status_note` | string | Administrative note the city wrote in the redemption field, for example VOID or BILLS PAID; null when a real party was published | | `is_redeemed` | boolean | True only when the certificate is redeemed and not void | | `latitude` | number | Latitude of the published property point | | `longitude` | number | Longitude of the published property point | | `source_record_id` | integer | Source record id | | `observed_at` | string | Timestamp when this record was read from the source | | `search_terms` | string | Full run search context, present on error rows only | | `error` | string | Error message when no records were returned or the source failed; error records are not charged | ### Input and filters All inputs are optional. | Field | Type | Required | Default | Description | |---|---|---|---|---| | `ownerNames` | array | no | (none) | Owner of record names to search, up to 20. Partial names are supported and matching is case-insensitive, for example SMITH, TRUST or PROPERTIES. Each name is searched separately and duplicate certificate rows are removed. | | `propertyAddress` | string | no | `""` | Partial Baltimore street address, for example NORTH AVE or 1923 W NORTH. Case-insensitive. | | `block` | string | no | `""` | Baltimore City block number, for example 0002 or 2. Numeric blocks are zero-padded automatically. Partial blocks are supported. | | `lot` | string | no | `""` | Baltimore City lot number, for example 026 or 26. Numeric lots are zero-padded automatically. Partial lots are supported. | | `taxSaleYears` | array | no | (none) | Tax sale years to include, for example 2023 or \[2022, 2023]. The published list covers 2019 through 2023.

Numeric districts are zero-padded automatically. | | `minTotalAmount` | number | no | `0` | Only certificates whose published total amount is at least this figure, in US dollars.

Leave empty for no upper limit. | | `redemptionStatus` | string | no | `"any"` | Include every certificate, only certificates with a published redemption date or redeeming party, or only certificates with no published redemption. Values: `any`, `redeemed`, `unredeemed`. | | `includeVoidCertificates` | boolean | no | `false` | Baltimore City marks some rows VOID in the redemption field. Void rows are excluded by default because their published total can be a placeholder rather than a real balance. Turn this on to return them too, with certificate_status=void. | | `sortBy` | string | no | `"sale_year_desc"` | Order of the returned certificates. The default puts the newest sale year first; amount sorts put the largest or smallest lien first. Values: `total_amount_desc`, `total_amount_asc`, `sale_year_desc`, `address_asc`, `owner_asc`. | | `maxFilings` | integer | no | `25` | Maximum number of certificate records to return and charge, 1-1,000.

Free Apify users receive up to 10 results per run. | A working example to paste into the Input tab: ```json { "ownerNames": [ "MERCHANT HILL" ], "includeVoidCertificates": true, "maxFilings": 3, "minTotalAmount": 0, "redemptionStatus": "any", "sortBy": "sale_year_desc" } ``` ### Use cases - Study certificates sold at Baltimore tax sales by year, block and lot, with redemption status and assessed value. - **Tax lien and tax deed investors** screening Baltimore certificates by amount, sale year and redemption status. - **Surplus-funds and redemption researchers** finding certificates with a published redemption and the party that redeemed. - **Distressed-property and vacant-property teams** combining Baltimore tax-sale records with their own outreach data. - **Real-estate attorneys, title researchers and closing teams** checking whether a Baltimore property appeared in a tax sale and what was owed. ### Coverage and freshness The published list covers the **2019, 2020, 2021, 2022 and 2023** tax sale years and contains **43,736 certificate rows**, of which **16,693** carry a positive total amount. The layer was last refreshed by the city in early 2025 and the newest published sale year is 2023; newer sale years are not in this source and are not invented by this actor. Rows the city publishes with a zero total are still returned, because they show the property, owner and sale year even when the certificate carried no balance. Filter with `minTotalAmount` to drop them. Rows the city marks `VOID` are excluded by default; enable `includeVoidCertificates` to return them with `certificate_status=void`. - Public-record research only. The output is not a consumer report, not an FCRA product, not a title examination and not legal, tax or investment advice. - Data comes from the city's public certificate list over HTTPS. - Baltimore City, not this actor, controls the list. - Sale-year coverage reflects the published source: 2019 through 2023. ### Pricing This actor uses pay-per-event pricing. These are the current Apify prices, read on 2026-11-06. | Event | Price | When it is charged | |---|---|---| | `result` | $0.015 | Each record delivered to your dataset | | `apify-actor-start` | $0.003 | When a run starts, once per GB of run memory with a minimum of one | At the default 512 MB, a run that delivers 100 records costs $1.503. - Apify asks for a maximum spend of at least $0.018 per run on this actor. - Accounts on the free Apify plan receive up to 10 results per run. - If nothing matches or the source fails, you get one row with an `error` field and no `result` charge.
