Extract Real Estate Listing Details Automatically
Stop manually recording property details. Automatically extract address, price, square footage, and amenities when property listings arrive in Notion.
Trigger
Page Created
Triggers when a new Notion page is created. Customer optionally scopes with at most one of: - data_source_id: new row in this data source - parent_page_id: new sub-page under this page (immediate parent only) With neither set, fires for any new page in the workspace the integration has access to. Notion sends ~60s aggregation latency on most events.
Action
Create Document
Tool to upload a new document for parsing. use when you have the document file or a public url and need to extract structured data immediately.
Why this helps
Real estate listings are long and unstructured. Extracting key details (price, square footage, amenities, condition) requires reading each listing multiple times. Comparing properties requires hours of manual work.
- Extract property details instantly
- Eliminate manual real estate data entry
- Compare properties quickly and fairly
- Build searchable property database
Setup
Build it in a few focused steps.
- 1Connect Notion and Affinda to Notis (portal setup).
- 2Create automation: 'Real Estate Listing Auto-Extraction'.
- 3Set trigger to 'Page Created' in your Notion Real Estate or Properties database.
- 4Write the automation: 'When a new property listing page is created, parse the listing with Affinda and extract: address, price, square footage, bedrooms, bathrooms, lot size, year built, property condition, major features, and HOA fees if applicable. Flag any properties below/above set price range.'
- 5Select notification channel and test with a current real estate listing.
Questions about this workflow
Does this work for MLS listings and online property listings?
Yes. Whether you upload a PDF, image, or text listing from Zillow or MLS, Affinda extracts the same structured data.
Can this identify properties that match specific buyer criteria?
Yes. Use Affinda's extracted data and create a follow-up automation that flags properties matching minimum/maximum criteria you define.
Does this capture inspection reports or property conditions?
Affinda extracts property condition from listing text. If you have inspection reports, you can upload those separately to capture detailed condition data.
Can this track comparable properties for pricing analysis?
Yes. Extract data from comparable listings, then track price per square foot and features to identify pricing outliers.

Supported Triggers and Actions
Notis builds workflows that link Notion to Affinda. A trigger fires from one place; an action lands in another.
Notion triggers
Affinda actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Batch Update Annotations
Tool to update multiple annotations in one request. use when you need to modify parsed values or other fields across many annotations at once.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create Collection
Tool to create a new collection. use after you have a valid workspace id and want to group documents by a specific extractor within that workspace.
All Page Events
Triggers when any Notion page is created or updated across the workspace.
Create Document
Tool to upload a new document for parsing. use when you have the document file or a public url and need to extract structured data immediately.
Comment Created
Triggers when a new comment is created in Notion. Optional `page_id` filter scopes to comments on a specific page. When omitted, fires for any new comment in the workspace the integration has access to. Requires the 'Read comments' capability on the Notion integration. If a connection was authorized before that capability was enabled, the user must re-authorize the connection for comment events to flow.
Create Organization
Tool to create a new organization. use when you have a unique organization name and want to group resources under it.
New Comment
Triggers when a new comment is added to a specified Notion block or page.
Create RESTHook Subscription
Tool to create a new resthook subscription. use after confirming your webhook endpoint is ready to receive document event notifications.
Database Created
Triggers when a new Notion database (the container) is created. A database is the post-2025-09-03 container that holds one or more data sources. This trigger fires for the container's creation event (`database.created`), distinct from `NOTION_DATASOURCE_CREATED` which fires when a new data source is added to an existing database. Most customers calling Notion's `POST /v1/databases` (the legacy API) or creating a database via the Notion UI will see this event. Adding a new data source to an existing database fires `data_source.created` instead — use `NOTION_DATASOURCE_CREATED` for that. Notion's payload puts `entity.type: "block"` (the container is a `child_database` block in the content tree) and `entity.id` is the database id.
Create Tag
Tool to create a new tag. use when you need to label documents in a specific workspace.
Data Source Created
Triggers when a new Notion data source is created. Fires workspace-wide. The payload's `data.parent` carries the data source's tree parent (typically the teamspace) for downstream filtering. A single template-based database creation can fire multiple `data_source.created` events at once — one per data source the template instantiates.
Create Validation Result
Tool to create a validation result. use when recording validation outcomes for a document after parsing.
Data Source Schema Updated
Triggers when a Notion data source's schema is updated. Fires on column add / remove / rename. Payload includes `data.updated_properties: [{id, name, action}]` so consumers can discriminate the kind of change downstream. Optional `data_source_id` filter scopes to schema changes on a single data source. When omitted, fires for any schema change in the workspace the integration has access to. Note: adding a column also fires `page.properties_updated` once per existing row in the data source. Customers wanting a single structural-change signal should use this trigger.
Create Workspace
Tool to create a new workspace. use when you need to programmatically create a workspace container within an organization.
