the strategic insight
For bridge loan providers, keeping tabs on borrowers’ property listings is critical for compliance and risk mitigation. Manual checks and delayed MLS updates leave gaps, especially when properties are listed “For Sale by Owner” on Zillow. Integrating a Zillow API that delivers structured, up-to-date listing data allows lenders to instantly verify compliance, proactively manage risk, and free staff from time-consuming manual monitoring.

Context
Who
A US-based real estate lender specializing in short-term bridge loans (under 6 months)
Trigger moment
The servicing team struggled with slow, incomplete MLS data and labor-intensive manual checks, risking missed violations when borrowers delayed or altered listings.
What we tried
and why it failed
Previous Approaches
- Manual property checks and borrower self-reporting
- MLS data feeds
Limitations
- Time-consuming, prone to delays, missed FSBO listings
- Not real-time, incomplete for non-MLS listings
The scraping
and enrichment workflow
01 Phase 1 — Collect
A daily batch of property addresses from the active loan portfolio is sent via REST API to HasData’s Zillow Property API.
02 Phase 2 — Process
A Python-based microservice normalizes the returned JSON data — current status, price updates, key property details — and loads it into a PostgreSQL-backed servicing database via a lightweight ETL pipeline.
03 Phase 3 — Act
The servicing platform displays the latest listing info for loan officers and compliance teams, triggering automated Slack and email alerts for any non-compliant properties (e.g., late listings, unauthorized price drops).
