Report Writing, Evidence and Professional Communication
A valuation report must be clear, complete, and defensible. It should state the client, the property, the purpose, the basis of value, the valuation date, the extent of inspection and investigation, the assumptions and special assumptions, the method and reasoning, and the opinion with its qualifications. The reasoning must be transparent enough for a peer to follow and, if necessary, for a tribunal to test.
Candidates must understand the difference between an assumption (a fact taken as true without verification) and a special assumption (a fact that differs from reality, such as vacant possession where a tenancy exists). Each must be stated and justified. Evidence must be relevant, recent, and comparable, and the report should explain adjustments. As an expert witness, the valuer's duty is to the tribunal, not the client, and the opinion must be independent.
Traps: omitting the basis of value or valuation date; failing to state assumptions; presenting conclusions without reasoning; and slipping into advocacy in an expert report. Another trap is relying on hearsay or unverified data without saying so.
Rule of thumb: a reader who has never seen the property should be able to follow the reasoning from facts to opinion without guessing.
Worked example: A report values a tenanted shop. If the opinion assumes vacant possession, that is a special assumption and must be labelled as such, with its effect explained, because the actual interest is subject to a lease.
Financial Mathematics and Investment Analysis
Financial mathematics underpins income valuation and investment analysis. Candidates must understand compounding and discounting, present and future value, net present value, internal rate of return, and the capitalisation relationship between income, rate, and value. They should also understand yields (initial, equivalent, and reversionary), the time value of money, and how risk is reflected in the discount or capitalisation rate.
Key formulas: future value = present value × (1 + i)^n; present value = future value ÷ (1 + i)^n; capital value = net income ÷ capitalisation rate; and net present value is the sum of discounted cash flows less the initial outlay. The internal rate of return is the discount rate at which net present value equals zero.
Traps: mixing nominal and effective rates; applying an annual rate to a monthly period without adjusting; capitalising gross rather than net income; confusing yield with return; and using a discount rate that does not reflect risk. Another trap is treating a higher initial yield as automatically better without considering reversionary potential and risk.
Rule of thumb: match the period of the rate to the period of the cash flow - annual rate to annual flows, monthly rate to monthly flows.
Worked example: Net income is 80,000 and the capitalisation rate is 8%. Capital value = 80,000 ÷ 0.08 = 1,000,000. If the rate rises to 10%, value falls to 800,000 - a 20% decline from a two-point rate change, showing the sensitivity of value to yield.
