Generate Custom CRE Comp Reports in 10 Minutes with AI
AI quickly generates custom CRE comparable reports by automating data extraction from sources like CoStar, Buildout, and Reonomy. The system normalizes this data and instantly populates your brokerage's branded client-ready presentation templates.
Key Takeaways
- AI automates CRE comp report generation by connecting to CoStar, Buildout, and Reonomy APIs to extract and normalize property data.
- The system populates your brokerage's branded templates automatically, cutting a 4-hour manual process down to 10 minutes.
- This requires custom Python data pipelines and a large language model like Claude to handle unstructured data extraction.
- A typical build for a 15-broker firm takes 4-6 weeks to connect 3 primary data sources.
Syntora designs AI automation for commercial real estate brokerages to generate custom comparable reports. A custom system connects to CoStar and Buildout APIs, cutting a 4-hour manual process down to 10 minutes. The architecture uses Python and the Claude API to extract and normalize property data into client-ready templates.
The project's complexity depends on the number of data sources and the structure of your templates. Integrating three API-based sources into a fixed Word template is a 4-week build. A system that also needs to parse PDF leases for terms would extend the timeline to 6 weeks.
The Problem
Why Do Commercial Real Estate Teams Still Build Comp Reports Manually?
Brokers currently rely on CoStar, Buildout, and Reonomy as primary data sources, not report generators. The "automation" these platforms offer is limited to exporting CSVs or basic PDFs. This leaves brokers spending hours manually copying and pasting data points into Word, PowerPoint, or Excel to create a client-ready document.
Consider a mid-market broker in Chicago preparing a presentation for a 100,000 sq ft office property. They spend the first hour pulling five comparable sales from CoStar and three lease comps from Buildout. The data formats are different; one uses price-per-square-foot, the other lists total sale price. The broker then spends another 90 minutes manually calculating metrics, reformatting addresses to a consistent style, and resizing property photos in a PowerPoint template. A last-minute change to a single comp requires redoing half the work.
The structural problem is data fragmentation. CoStar, Buildout, and Reonomy do not integrate with each other, and their business models depend on keeping users inside their platforms. Their APIs provide raw data but lack the logic to normalize it (e.g., standardizing "N. Michigan Ave" and "North Michigan Avenue") or map it intelligently into a client-facing narrative. They are databases, not workflow engines.
This manual work consumes 2-4 hours per property, time that could be spent on client-facing activities. For a 20-broker firm generating five reports a week, this translates to over 400 hours of lost productivity per month. The manual data entry also introduces a high risk of errors that can damage credibility in client presentations.
Our Approach
How Syntora Architects an Automated Comp Report Generator
The first step would be an audit of your current data sources and reporting templates. Syntora would map every field you pull from CoStar, Buildout, and Reonomy and document the business rules for normalization. You would receive a detailed data flow diagram showing exactly how information moves from source to final report before any code is written.
The system would be a Python-based data pipeline using the Claude API for its large context window, ideal for parsing long property descriptions. A FastAPI service would expose a simple internal endpoint where a broker inputs a subject property ID. The service calls the CoStar, Buildout, and Reonomy APIs in parallel using httpx, normalizes the returned data with Pydantic models, and stores the structured results in a Supabase Postgres database. This architecture provides a response in under 60 seconds and would run on AWS Lambda for cost-effective execution, typically under $50 per month to operate.
The final deliverable is a simple web interface for your brokers. They enter a property address, select a template, and click "Generate." The system returns a fully formatted Word or PowerPoint file in under 10 minutes. You receive the complete source code, a runbook for maintenance, and full control over the system running in your own AWS account.
