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.

The Heatmap Housing Way

  • Filter U.S. ZIP codes by modeled cash flow, DSCR, and price range
  • See projected rent, tax, insurance, and expense assumptions instantly
  • Compare rent comps, sale comps, and tax history in one view
  • Identify viable deals before contacting an agent
  • Export structured deal summaries ready for partners or lenders

This isn’t more data.
It’s faster capital allocation.

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.
