Know the land
before you move on it.

You're walking a client through a listing before the offer deadline. The seller's agent quotes the assessed value. You pull up Atlas while still in the driveway. Zone A-2, 65 ft height limit, 2.2 FAR — it's a development play, not just a home. Flood zone AE, BFE 10 ft. Last recorded sale was $1.15M in 2022, assessed today at $890K. The gap between sale price and assessment is a signal worth digging into before your client writes a check.

Before driving to a site visit for a new construction bid, pull up the parcel. R-5 zone means a 5,000 sf minimum lot — the lot is 6,200 sf. Front setback 20 ft, rear 15 ft, side 5 ft each. No permits filed in the last three years. You can calculate the legal building envelope — roughly 62 by 40 ft of buildable pad — before you leave the office. When the client walks you through what they want, you already know whether the footprint is legal and whether it will require a variance.

Scanning AG-2 parcels on the west side of Hawaii Island for undervalued land. Pull up a 3.1-acre lot listed at $295K. Atlas shows lava zone 6 — Hualalai last erupted in 1801, manageable risk. Flood zone X, no FEMA exposure. No permits in the last decade. One farm dwelling on record, agricultural use unclear. Comparable AG-2 Zone 6 parcels with recent activity are trading at $85–95K per acre. This one is at $95K per acre — priced correctly for what it is, not an outlier. Pass, and move to the next one.

You're developing a mid-rise on a parcel in Kaimuki. Three lots across the street are owned by an entity you don't recognize. You set a change alert on all three. Six weeks later: a building permit is filed on the corner lot — new structure, 28 units, 65 ft height. You now know your future context six months before any signage goes up, before the neighborhood association finds out, and well before anyone asks you about it at a planning meeting.
