Market Analysis and Highest and Best Use
This domain tests market analysis and the four-test highest and best use (HBU) sequence. You must show that an inferred use is legally permissible, physically possible, financially feasible, and maximally productive.
Core rules
- HBU can be the existing use if it passes all tests. Test the site as if vacant and the property as improved.
- Legal permissibility comes first: zoning, title restrictions, environmental rules, and consents.
- Physical possibility covers site area, access, topography, services, and building constraints.
- Financial feasibility compares realistic revenue, cost, and required return; maximally productive chooses the highest residual value.
- Market analysis supports these tests: demand, supply, absorption, vacancy, rents, and competitive position.
Worked example
A 1,000 sqm site allows residential or retail use. Residential yields a residual land value of 600,000 after construction and profit; retail yields 450,000. Residential is legally permissible, physically possible, and financially feasible. It is maximally productive, so it is the HBU. If residential were not permitted, the answer changes even if it looks more profitable.
Traps
- Calling current use the HBU without testing alternatives.
- Skipping the legal test because a use is profitable.
- Using optimistic rents or ignoring demolition costs.
- Testing as improved when the instruction requires as if vacant.
- Confusing market demand with a single developer's opinion.
