We built the underwriting tool
we wish we had.
One platform to prospect, underwrite, and close investment deals — powered by real MLS data. Built for Texas investors who don’t have a full acquisitions team, but want to operate like they do.

To clear your daily bid list
Everything you need to find and analyze deals.
Real data. Real speed.
Whether you’re flipping, wholesaling, or building a rental portfolio — Zephyr replaces your comping tool, your spreadsheets, and your MLS workarounds.
Zephyr Score — opportunity scoring
Every property gets scored based on spread, days on market, price history, and market dynamics. Stop guessing which deals to chase — let the data surface the best opportunities.
Comp analysis with editable filters
Pull real MLS sold data — not Zillow estimates with a 7% error rate. Adjust comp radius, date range, beds/baths, and sq ft. On a $300K property, that 7% is a $21K swing.
Flipped Properties Map
See every recent flip in your market — before price, after price, spread, and timeline. Spot patterns, find hot neighborhoods, and learn what the market actually pays.
Flip & LTR underwriting
Run a full deal analysis in under 5 minutes — ARV, rehab estimate, and projected returns for both flip and long-term rental strategies. Lease comps included.
Explore page — better than MLS matrix
Interactive map, advanced filters, instant property data. Designed for investors, not agents. Search the way you actually work.
Saved searches with instant alerts
Set your criteria once. Get notified the moment a matching property hits the market. First to know, first to make an offer.
Texas-deep, not national-shallow.
Live in Austin, Houston, and San Antonio — with more Texas markets coming soon. Real MLS feeds, neighborhood-level data, and local market knowledge because we flip in these markets too.
See your deals come together
From sourcing to underwriting, every step in one place.
What investors are saying
Texas flippers and investors using Zephyr to find and close deals faster.
Alec Hawthorne
Founder & Wholesaler · Fairway
“The speed difference is night and day. I used to spend 45 minutes pulling comps and running numbers on a single property — now I get real MLS data and a full underwrite in under five minutes. When you're submitting 15-20 offers a week, that kind of time savings lets me move on deals before other wholesalers even finish their analysis.”
Blake Foote
Partner & Agent · Silver Group at Compass
“The comp data quality is what sold me. I advise investor clients who are putting serious capital to work, and they need ARVs they can trust — not Zestimate guesses. Zephyr lets me pull actual sold comps, adjust the filters, and walk a client through the numbers in real time. It's replaced three different tools I was cobbling together before.”

“The Zephyr Score completely changed how I prioritize my morning bid list. Instead of manually eyeballing 30 properties, I sort by score and focus on the top ten. I'm clearing my list in a fraction of the time and my offer-to-contract ratio has gone up since I started using it. The subscription pays for itself in the first week.”
