Real property valuation in a connected world

Real property is the most local of asset classes: every parcel is fixed in place, priced in a local market and governed by local law. Yet the capital that flows through property — mortgage lending, institutional investment, securitised portfolios — is anything but local. That tension explains why the framework surrounding real property valuation has steadily internationalised, and why a residential valuer in one market and a fund valuer in another increasingly work to the same underlying reference points.

IVS 400 and the standards behind it

Within the International Valuation Standards, real property has its own asset standard — IVS 400 Real Property Interests — sitting alongside IVS 410 Development Property in the family of Asset Standards. As with every IVS engagement, the General Standards do the structural work: a defined scope of work, a stated basis of value, a justified approach, scrutinised data and inputs, and documentation that allows the reader to follow the reasoning. For property valuers, much of this codifies long-standing good practice; its force comes from being the same discipline everywhere.

Where standards appear in the mortgage chain

European mortgage and banking frameworks illustrate how internationally recognised valuation standards now thread through the lending process at several distinct points.

The professional layer: the Red Book

Professional standards complete the picture. The RICS Red Book Global Standards apply to RICS members and regulated firms globally and fully incorporate IVS; the current edition, effective 31 January 2025, incorporates the IVS published on 31 January 2024. A valuer complying with the Red Book is therefore working within the IVS framework whether or not a client ever asks for it by name — one of several routes by which IVS reaches property practice in more than 100 countries.

What this means at the desk

For the individual property valuer, the connected framework changes the audience more than the task. A valuation prepared for a local lender may later be read by a supervisor, an investor’s auditor or a counterparty in another jurisdiction, each testing whether the basis of value was appropriate, the evidence sufficient and the assumptions disclosed. The General Standards exist precisely so that the answer does not depend on where the report was written. In a market where property is local but scrutiny is global, that consistency is the working valuer’s best protection.
