Do you connect to or scrape CoStar?

No. NextAutomation does NOT connect to CoStar, does not have or imply a CoStar API, does not scrape CoStar, and does not extract, store, or redistribute any CoStar data. CoStar has no sanctioned public API, and its terms of service expressly prohibit automated or programmatic access — which CoStar actively enforces. Any 'CoStar integration' that implies a direct connection is misrepresenting what is both technically and legally possible. Our entire approach is works-alongside only: your team keeps using CoStar normally under your own license, and automation runs beside it, acting only on data you have manually put into your own systems. This is both fully compliant and a deliberate differentiator from shady scrapers who put your subscription at risk.

Then what exactly do you automate if you never touch CoStar?

We automate everything around CoStar — the manual relay that surrounds your research. When an analyst finds something in CoStar and acts on it in your own tools (logs a prospect, queues a research task, advances a deal), automation takes over: it enriches the record from your own licensed and public data sources, launches a personalized outreach sequence, assembles a market brief from public data, or drafts an IC packet from data already in your CRM and document set. CoStar stays the place your team reads the market; we remove the busywork between 'I found something in CoStar' and 'the surrounding work is done.'

Is this compliant with CoStar's terms of service?

Yes, because automation never accesses CoStar. The compliance boundary is built into the architecture: every workflow is triggered by a human action inside your own systems and acts only on data already in those systems. There is no automated login, no query, no scrape, and no extraction or redistribution of CoStar data — there isn't even a CoStar credential stored anywhere in the automation. Your CoStar usage stays exactly as it is today, performed manually by your licensed team. The automation lives entirely on your side of the line, so there is no terms-of-service exposure.

How does the workflow start if you can't read CoStar?

It starts with a human action in your own systems. An analyst, working in CoStar normally under your license, decides a finding is worth acting on and manually logs it — creates a prospect record in your CRM, queues a market-research task, or advances a deal stage. That action in YOUR tool is the trigger. Automation never observes, polls, or reads CoStar; it only responds to the data your team chooses to capture. This keeps a human firmly in control of what crosses from CoStar into your automated workflow.

Where does AI add value if it isn't analyzing CoStar's data?

The AI runs on YOUR data, never CoStar's. It cannot and does not interpret, query, or re-host anything in CoStar. What it does is take the deal facts your team has already captured in your CRM and your own document set and turn them into leverage: scoring your pipeline against your buy-box, drafting personalized outreach rationale, assembling a market brief from public data, or producing a first-pass IC narrative. The value isn't a forbidden pipe into CoStar's database — it's eliminating the manual steps between a CoStar finding and a finished downstream deliverable, using only data you own and are licensed to use.

Can you enrich a property I found in CoStar?

Yes — but the enrichment comes from your own licensed and integrator-friendly sources, not from CoStar. When you manually log a CoStar-sourced address in your CRM, automation rounds out the record using documented parcel and tax data APIs, public records, and your own CRM history. For example, you can attach ATTOM property and ownership data to a target you sourced in CoStar (see our [ATTOM integration](/integrations/attom)), or unify your owned data sources through a platform like [Cherre](/integrations/cherre). CoStar provides the human-sourced seed; compliant external data grows it into a complete record — all without any programmatic access to CoStar.

How does this fit with the other CRE data tools I use?

CoStar sits in the sourcing and market-data layer of your stack alongside tools like Reonomy and CompStak — each with its own access model. Reonomy and CompStak offer customer-authorized, partner-gated APIs for your own licensed access, while CoStar is strictly works-alongside (no API at all). The automation layer sits above all of them: it acts on whatever your team has compliantly brought into your own systems and removes the manual relay around each tool. For the full picture of how these pieces fit together — and where AI changes the math at each layer — see our guide, [The Complete CRE Software Stack](/blog/best-cre-software-complete-stack).

CoStar Integration

Data & Market Intelligence

What It Does

CoStar is the dominant commercial real estate data and analytics platform — the system of record most institutional acquisitions, leasing, and research teams open first. It covers properties, sale and lease comparables, tenant and ownership data, availability, and submarket analytics across virtually every U.S. commercial market. For most CRE firms, a CoStar subscription is the baseline market-intelligence layer the rest of the workflow is built around.

Why Real Estate Professionals Use It

CRE teams don't lose time inside CoStar — they lose it in the workflow around CoStar. An analyst finds a promising owner or a fresh comp, then context-switches into a CRM, a spreadsheet, an outreach tool, and a deck template, retyping the same handful of facts into four systems. That ritual is where hours disappear, and it scales badly when you are screening dozens of opportunities a week. The CoStar subscription is doing its job; the manual relay around it is the bottleneck.

Feature

Works-Alongside Automation (No Connection)

NextAutomation builds workflows that run beside CoStar — never against it. There is no CoStar API, no automated login, no scraping, and no extraction of CoStar data. You keep using CoStar normally under your own license; automation acts only on the facts you choose to bring into your own systems.

Real Estate Impact

This is the only compliant way to get automation value around CoStar. Your subscription and your team's licensed usage are untouched, so there is no terms-of-service exposure — automation simply removes the manual relay that surrounds the research you already do.

Automation Workflows

Ready-to-deploy workflows powered by CoStar + NextAutomation

Workflow 1 of 3

Intermediate

CoStar-Sourced Prospect Logged → Enrich + Outreach Sequence

An analyst working in CoStar finds a promising owner or property and manually logs it as a prospect in your CRM. That manual capture — in your own system, never a read from CoStar — triggers compliant enrichment from your licensed and public data sources and launches a personalized outreach sequence. No part of this workflow connects to, queries, or scrapes CoStar; it acts only on the record your analyst chose to create.

Trigger: New prospect record manually created in your CRM (HubSpot, Airtable, or Salesforce) by an analyst working from CoStar

Workflow Steps

1Analyst, working in CoStar under their own license, identifies a target and manually creates a prospect record in your CRM with the address and any notes they choose to capture

2CRM webhook fires to n8n on the new record — automation begins only after the human has put data into your own system

3n8n enriches the address from integrator-friendly and public sources you are licensed to use (parcel/tax data via a documented API, public records, prior CRM history) — CoStar is never queried

4AI node drafts a personalized first-touch outreach note from the enriched record and your deal context

+2 more steps

The hours an analyst would spend retyping a CoStar finding into the CRM, enriching it, and drafting first contact collapse into a single manual log entry. Compliance is preserved because automation never touches CoStar — it acts only on data your team chose to capture.

Triggers & Actions

Connect CoStar to your workflows with powerful triggers and actions

Triggers

Prospect Manually Logged in Your CRM

Fires when an analyst manually creates a prospect or property record in your own CRM after researching it in CoStar. The trigger is the human action in your system — automation never observes or reads CoStar.

An analyst finds a long-hold owner in CoStar and logs the address in HubSpot; that record creation kicks off compliant enrichment and an outreach sequence around it.

Market-Research Task Queued

Fires when an analyst creates a research task in your task manager or via an intake form. Used to start public-data brief assembly around a submarket the analyst will research in CoStar separately.

An analyst queues 'Q3 industrial — Inland Empire' as a task; automation assembles the public-data scaffold of a brief for them to layer their CoStar insight onto.

Deal Stage Advanced in Your Pipeline

Fires when a deal moves to a new stage (e.g., IC Review) in your own CRM or pipeline tool. Drives downstream packet or notification workflows from your own deal data.

A deal advances to IC Review and automation assembles a first-draft IC packet from the data your team has already entered into the CRM and model.

Actions

Enrich a Logged Record From Compliant Sources

Enriches a prospect or property record using integrator-friendly and public data sources you are licensed to use — documented parcel/tax APIs, public records, and your own CRM history. Does not query, read, or extract any CoStar data.

After an analyst logs a CoStar-sourced address, enrich it with ownership entity, parcel, and tax context from your own licensed providers to complete the record.

Launch an Outreach Sequence

Enrolls a logged prospect into a personalized, multi-touch outreach sequence drafted from your own CRM and deal context and sent from your own email and channels.

A newly logged prospect automatically receives a personalized first touch and a scheduled follow-up cadence, all from data in your own systems.

Assemble a Public-Data Market Brief

Gathers public and integrator-friendly data for a named submarket and structures it into a market-brief draft, with clearly marked sections for the analyst to add their own licensed CoStar context manually.

Produce the demographic, parcel, and public-record scaffold of a submarket brief so the analyst only adds the CoStar-sourced color their subscription provides.

Generate an IC Packet Draft

Compiles a first-draft investment-committee packet from data already stored in your own systems — CRM fields, uploaded documents, and figures your team manually entered. Pulls nothing from CoStar.

When a deal hits IC Review, assemble the deal summary, financials, and narrative draft from your own captured data for the committee to review and refine.

Notify the Deal Team

Sends a Slack or email notification summarizing what automation completed — enrichment done, sequence live, brief or packet drafted — keeping the analyst in the loop without manual status checks.

After enrichment and sequence launch, post a one-line Slack confirmation to the analyst so they know the workflow around their CoStar finding is handled.

Setup Guide

Get started in approximately 1 hour for the compliance boundary plus the prospect-logged enrichment and outreach workflow; 2-4 hours to add the brief and IC-packet assembly workflows

Prerequisites

Your own active CoStar subscription, used normally under your license — NextAutomation does not provision, connect to, or access CoStar in any way
A CRM or pipeline tool you control (HubSpot, Salesforce, or Airtable) where analysts manually log CoStar-sourced findings
n8n instance (cloud or self-hosted) to orchestrate the workflows that run beside CoStar
Licensed and integrator-friendly enrichment data sources for the around-CoStar steps (e.g., a documented parcel/tax data API, public-record sources) — never CoStar
Your own email/outreach channels and document templates (Google Docs/Sheets) for sequences, briefs, and IC packets

Confirm the Compliance Boundary First

Before building anything, establish the rule that defines this entire integration: automation never connects to, logs into, queries, scrapes, or extracts data from CoStar. Your team continues using CoStar manually under your own license. Every workflow is triggered by a human action in YOUR systems (a logged record, a queued task, an advanced deal) and acts only on data inside those systems. Document this boundary so anyone extending the workflows later preserves it.

Make it a hard rule in your workflow naming: prefix every automation with 'around-costar-' so it's visually obvious these run beside CoStar and must never reference it. There is no CoStar credential to store anywhere in n8n — if one ever appears, something is wrong.

Set Up the Manual-Capture Trigger in Your CRM

Decide where analysts will log CoStar-sourced findings (e.g., a 'Prospects' object in HubSpot or a table in Airtable). Configure a webhook from that system to n8n so that creating a new record fires the downstream automation. This human log entry is the only entry point — automation starts after the analyst has put data into your own tool.

Add a required 'source' field to the record and default it to a value like 'analyst-sourced' so it's clear the data originated from a human's licensed research, not an automated pull.

Build the Enrichment Step From Compliant Sources

In n8n, after the new-record trigger, add HTTP Request nodes that enrich the logged address from sources you are licensed to use — a documented parcel/tax data API, public-record lookups, and your own CRM history. Map the returned fields back to the CRM record. Crucially, none of these calls go to CoStar; they round out the record around the CoStar-sourced address using compliant data.

Reuse a single 'compliant-enrichment' sub-workflow across all your around-CoStar automations so the list of approved data sources lives in one place and can be audited at a glance.

Wire the Outreach Sequence

Add an AI node to draft a personalized first-touch message from the enriched record, then connect your own email/outreach tool to enroll the prospect in a multi-step sequence. Sends go out from your own accounts, using your own data — entirely independent of CoStar.

Gate the first send behind a quick human approval step initially, so analysts can confirm the AI drafted an appropriate outreach before it goes live. Remove the gate once you trust the drafts.

Add the Brief and IC-Packet Assembly Workflows

Build the market-research workflow (task trigger → gather public data → structured brief draft with marked CoStar-input sections) and the IC-packet workflow (deal-stage trigger → pull your own CRM/document data → assemble draft packet). Both produce drafts your team reviews and completes with their manually sourced CoStar context. Activate the workflows and monitor the first runs.

In every generated brief and packet, insert an explicit placeholder block labeled 'Add your licensed CoStar context here' so the human-in-CoStar step is built into the template, never skipped or automated away.
