Welcome to the InterVal blog, your go-to source for the latest news, updates, and insights in property valuation
An audit trail sounds like bureaucracy; it is the opposite — the record of how a valuation was reached, and the only thing that lets a reviewer, insurer or regulator rely on it years later. What a defensible audit trail contains, where the RICS Red Book and IVS require it, why files fail without one, and why it should be captured as you work rather than reconstructed from memory.
Valuation files are some of the most sensitive data a professional handles — so is the cloud safe for them? A practical framework from InterVal's technology lead: what real cloud security looks like (encryption, access control, audited hosting, data residency, backups, audit trail, data ownership), the questions to ask any vendor, and why the real risk is usually the laptop-and-email workflow, not the cloud.
A practitioner's honest guide to choosing property valuation software: the eight criteria that actually matter — compliance built in, end-to-end workflow, methods, audit trail, collaboration — the red flags to avoid, and the cases where software isn't the answer at all.
A founder's view on where property valuation is heading: abundant data, automation of the routine, compliance built into the workflow, ESG as a value driver, and the widening gap between modernised and unmodernised firms — plus the one thing that doesn't change.
DCF is the right method whenever a property's income changes over time — but done badly it's a black box. What DCF is, where it sits in IVS and the Red Book, when to use it instead of income capitalisation, the five steps, and the three inputs that make or break the answer.
ESG is no longer optional in valuation. With the RICS ESG standard mandatory since 30 April 2026 and ESG embedded in the Red Book and IVS 2025, here's what ESG means inside a valuation, where it now sits in the rules, the valuation-vs-strategic-advice distinction, and what it changes in day-to-day practice.
The same property can carry several correct values on the same day. A reference guide to the six IVS bases of value — Market Value, Market Rent, Investment Value, Equitable Value, Synergistic Value and Liquidation Value — when to use each, and the Fair Value naming trap.
Why most valuation practices still run on Word and Excel, where that workflow quietly costs you — version chaos, silent formula errors, compliance drift, no audit trail — and when a structured platform is worth the switch.
What the RICS Red Book requires in practice: the 2025 edition's six VPS explained stage by stage, the most common compliance failures, and a practical checklist for defensible valuation files.
