da·tum, n. — a fixed reference from which measurements are made.
Where value is measured from.
Datum is an independent commercial real estate valuation and advisory practice serving institutional lenders and investors across the New York metropolitan region. The work is built for credit decisions: direct market evidence, disciplined reconciliation, and conclusions that hold under review.
Why Datum
In surveying, a datum is the reference point every measurement is taken from — a benchmark set in bedrock, or mean sea level itself. Nothing on the plan can be trusted until it ties back to that point.
An appraisal is meant to be that for a transaction. The lender, the borrower, and the market each carry their own numbers and their own incentives; a credible opinion of value is the one point they can all measure against. We named the practice for the standard the work is held to.
Practice
Valuation
Lender-grade appraisal for mortgage origination, portfolio monitoring, and workout. Reports are prepared to institutional review standards, with the evidence and the reasoning shown on the page.
Advisory
Feasibility and highest-and-best-use studies, market and marketability analysis, litigation support, and valuation consulting for complex or contested assignments.
Research & Data
A proprietary market-data platform underpins every engagement — comparable evidence, market indicators, and economic context maintained continuously rather than assembled per assignment.
Coverage
- New York City
- Long Island
- Westchester & the Hudson Valley
- Northern New Jersey
- Connecticut
Across those classes, the practice emphasis is retail, mixed-use, and complex assignments where the evidence requires judgment.
Standards
INDEPENDENCE
Valuation only. No brokerage, no financing, no asset management — no interest in the outcome of any transaction we opine on.
DESIGNATION
Every assignment is performed by an MAI-designated appraiser, bound by the Appraisal Institute’s Code of Professional Ethics, Standards of Professional Practice, and continuing-education requirements.
COMPLIANCE
Every report is prepared in conformity with USPAP. Assignments for regulated lenders meet FIRREA requirements and the Interagency Appraisal and Evaluation Guidelines.
CONFIDENTIALITY
Assignment facts, data, and results stay inside the engagement. Client matters never appear in our marketing.
Contact
Engagements begin with a conflict check and a defined scope of work.
