Why This Is Different
One Platform That Replaces Your Deal Stack.
Market discovery + modeled underwriting + export-ready execution — with sourced assumptions you can audit.
Visualization-First
See the entire country as a live heatmap. Filter by your criteria and spot opportunity fast — before you waste time underwriting listings.
ZIP → Property in One Click
Start at the market level, then drill into a single property without switching tools. Listings, rent comps, tax history, and underwriting — in one view.
Every Number Is Auditable
No black boxes. Each assumption shows its source and a confidence indicator so you can verify, override, and move forward with clarity.
Instant & Fully Hosted
No installs. No downloads. Open your browser and the platform is live — markets, properties, underwriting, and exports.
Your Process Is the Bottleneck
Effort isn’t the problem. Workflow is.
The Old Way
- Scan listings one by one
- Build spreadsheets for every property
- Guess at rent, taxes, and insurance
- Research comps manually or across several platforms
- Waste hours underwriting deals you never offer on
- Miss stronger markets because you don’t have time to compare them
Scaling investors don’t lose because they lack effort.
They lose because their process doesn’t scale.

Trusted Data, Full Transparency
Real numbers from real sources — every one auditable
HUD Fair Market Rent
Government-published rent baselines updated annually by HUD. ZIP-level (SAFMR) and metro-level (FMR) data for voucher rent underwriting.
MLS & Listing Data
Active listings refreshed daily. Rental comps and sale comps from MLS-derived data feeds. Property-level data enriched every 30 days.
Census & Demographics
Population, median household income, unemployment rate, and growth trends. Updated annually from U.S. Census Bureau data.
Sale & Tax Records
Ownership records, tax assessments, deed history, and transaction data from county-level public records.
How it works: ZIP-level analysis combines HUD Fair Market Rent data, actual median sale prices, Census demographics, and MLS data — pre-calculated and ranked based on your criteria. Each ZIP includes a Data Quality grade so you know how much data backs the estimates.
Property-level: Every underwriting field is pre-filled from sourced data — rent comps, taxes, insurance estimates — each with a confidence indicator. Adjust any value to match your deal. The analysis updates instantly.
Data freshness: Listings refresh daily — you always have yesterday’s data. Market heatmaps update monthly. Property enrichment (ownership, tax, comps) refreshes every 30 days. Pro unlocks current-month snapshots — no rolling averages, just now.
Confidence indicators: Every field in the Deal Analyzer shows a badge indicating how the number was derived. If a rent estimate is based on nearby rental comps, you’ll see that. If a tax value comes from county records vs. an estimate, you’ll see that too. You know exactly what backs each number — and you can override any value if your local knowledge is better.
Built for How You Actually Invest
Three investors, three workflows, one platform
The Out-of-State Investor
Screen 15 markets in an hour, not a week. See which ZIPs actually cash flow before you ever call an agent. Toggle between market rent and voucher rent to find the strategy that works for each market — all from your browser, no local knowledge required to start.
The BRRRR Investor
Model the full cycle — purchase, rehab, rent, refinance — with real numbers, not guesses. The Deal Analyzer calculates your cash left in deal and post-refi cash flow, then gives you a clear verdict: does this BRRRR work, partially work, or fail? Know before you commit capital.
The First-Time Investor
Every number shows where it came from. No spreadsheet required. Start with the heatmap, find green ZIPs, drill into properties, and get a full underwriting with confidence indicators on every field. You’ll know what to trust before you make an offer.
Stop Underwriting Deals You’ll Never Offer On.
