Built for investors who treat rentals like a business.

Two Rent Views. One Decision.

Underwrite the same deal under two rent assumptions — without rebuilding your analysis.

Market Rent

What tenants are paying in the open market. Derived from comparable rental listings and local data. This is the baseline for conventional rentals.

HUD SAFMR / FMR (Reference Baseline)

Reference baselines published by the U.S. Department of Housing and Urban Development. SAFMR is ZIP-level; FMR is metro-level. Heatmap Housing integrates both so you can model voucher-lens scenarios inside the same workflow.

Important: HUD SAFMR/FMR are reference baselines — not guaranteed rent. Actual voucher payment depends on local PHA payment standards, rent reasonableness, utility allowances, and inspections.

CLEAN BRRRR

All your capital comes back and the property cash flows after refinance.

Cash left in deal ≤ $0 • Post-refi cash flow > $0

PARTIAL BRRRR

Some capital stays in the deal, but the property still cash flows after refinance.

Cash left in deal > $0 • Post-refi cash flow > $0

CASH OUT, NO FLOW

You get your capital back, but the refi payment kills cash flow.

Cash left in deal ≤ $0 • Post-refi cash flow ≤ $0

NO GO

Capital trapped in the deal and no cash flow.

Cash left in deal > $0 • Post-refi cash flow ≤ $0

Most tools show a number. Heatmap Housing tells you what the number means for your strategy.

Common Questions From Active Buyers

Frequently Asked Questions

How fast can I go from map to underwriting?

Seconds. The map is live when you open it. Click a ZIP, see properties, click a property, and the Deal Analyzer opens with every field pre-filled from sourced data. Modeled assumptions are editable — adjust and the analysis recalculates instantly.

Where does the data come from?

MLS listings, rental comps, HUD Fair Market Rents, Census demographics, household income, property ownership records, tax history, and sale transactions. Every value in the Deal Analyzer shows its source and a confidence indicator so you can verify before you act.

Do I need to be a voucher investor?

No. The dual-rent toggle lets you underwrite the same property under market assumptions and HUD reference baselines, side by side. Most users invest conventionally and use the voucher view as a secondary lens.

How do you rank deals?

Every property is scored against your modeled assumptions — your down payment, rate, and expenses. Cash flow, cap rate, and DSCR are calculated and color-coded from green (strong) to red (weak). The ranking reflects your inputs, not a generic algorithm.

Can I export an analysis and send it to my agent?

Yes. Export structured deal summaries with property details, modeled financials, and deal stage — ready to send to your agent, partner, or lender.

Is HUD rent what I’ll actually get paid?

Not exactly. HUD publishes Fair Market Rent (FMR) and Small Area FMR (SAFMR) as reference baselines. Actual voucher payment depends on your local PHA’s payment standard, rent reasonableness, utility allowances, and inspections. We show the baselines so you can model scenarios, then verify with your local PHA.
