CONFIRMED REGULATORY POSITION — The Estate Surveyors and Valuers Registration Board of Nigeria describes itself as the statutory regulator of estate surveying and valuation practice across Nigeria. Its public verification portal allows a user to search a practitioner by name or registration number and view the person’s licence status. The regulator states that only ESVARBON-licensed Estate Surveyors and Valuers are authorised to sign and seal valuation reports in Nigeria.

CONFIRMED DOCUMENT CONTROL — ESVARBON’s published guidance lists valuation and appraisal reports among the documents that must carry its professional adhesive stamp. Its portal also identifies the revised Nigeria Valuation Standards 2025, known as the Green Book, as the current professional valuation guide. These controls concern the professional standing and form of the report; they do not, by themselves, guarantee that every assumption or input is correct.

BLUEGATE ANALYSIS — Four figures are often confused in property negotiations. The asking price is the seller’s opening position. A marketplace median summarises advertised stock. A government fair-market-value schedule may support statutory assessment. A professional valuation estimates value for a defined property, purpose and date using evidence and stated assumptions. Treating any one of the first three as a substitute for the fourth can distort a purchase, lending decision or joint-venture sharing ratio.

THE REPORT-IDENTITY TEST — Before relying on a valuation, match the practitioner’s name, registration number and firm to ESVARBON’s current public record. Confirm that the report identifies the client, exact property, interest valued, valuation date, purpose, inspection date, methodology, material assumptions, evidence and limiting conditions. The property description and survey information should reconcile with the title and the physical asset inspected.

THE EVIDENCE TEST — A large final figure is not analysis. Ask which comparable transactions or rentals were used, when they occurred, how close they are to the subject property and what adjustments were made for location, title, size, condition, services, tenure and development potential. Advertised prices may inform the investigation, but completed evidence and defensible adjustments should carry greater weight where available.

THE JV CONSEQUENCE — In a development joint venture, an unsupported land value can make a proposed sharing percentage look attractive while leaving the project commercially unworkable. BlueGate recommends testing land value alongside planning capacity, buildable and saleable area, construction and finance costs, expected prices, absorption period and each party’s enforceable contribution. The valuation date also matters because costs and market conditions can move before execution.

BLUEGATE POSITION — Every premium acquisition, secured transaction and development mandate should carry a valuation status: Seller Asking Price, Marketplace Indicator, Government Assessment Basis or Independent Professional Valuation. Where a professional report is material to the decision, BlueGate should record the valuer-verification result, report date, purpose, evidence reviewed and any unresolved assumptions before presenting the figure as decision-ready.

PRACTICAL ACTION — Verify the practitioner first, then interrogate the property evidence. A recognised name, branded document or confident price opinion is not enough. The safest number is one whose author, professional standing, subject property, valuation purpose, evidence and assumptions can all be traced.
