How it works

The whole city, narrowed to your next deal

The underwriting workflow you run by hand — done for you, ranked, and scored for how likely each site is to actually trade.

01 · Find

Surface

Every underused, developable site in the city — ranked by opportunity, with the owner's likelihood to sell already scored into where each one lands.

02 · Underwrite

Value

Best-use massing → income pro forma → levered IRR in one click. See your rational bid — the most you can pay and still hit your return — against real land comps.

03 · Act

Approach

The deal-gap tells you whether the owner's likely price fits what development supports — then reveal the owner's phone and email and approach with a number in hand.

The method

Underwriting that respects the uncertainty

Transparent and honest by design — never false precision on numbers that can't support it.

Rational bid, not a guess

The max land price for your target levered IRR — discounted over the real build timeline. Leads with what you can pay, not a comp that makes good deals look bad.

Deal-gap = odds of transacting

Your rational bid against what nearby sales imply the seller wants. Positive means room to meet the market; negative means it needs a negotiation.

Land comps priced on the dirt

Size-matched land values only — so garages and office towers never pollute the number you're pricing against.

Owner contact, built in

When the math clears, reveal the owner of record's phone and email — 100 reveals a month, DNC and litigator flags included — and start the conversation.
