Core concepts
Concept 1
Cost Approach, Cost Sources, and Depreciation questions reward the answer that follows the official source, the professional role, and the stated facts.
Exam cue: Identify the candidate role, client or public risk, source rule, calculation, or process step being tested.
Concept 2
The strongest answer identifies the rule, safety concern, ethical duty, calculation, client factor, or process step before acting.
Exam cue: Check whether the fact pattern is using a national standard, jurisdiction rule, handbook policy, or scenario-specific instruction.
Concept 3
Eliminate answers that ignore requirements, skip documentation, overreach the role, or treat convenience as the standard.
Exam cue: Choose the compliant and professionally scoped answer before the convenient or familiar answer.
Risk pitfalls and guardrails
Treating related standards as interchangeable without checking the source.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Skipping screening, documentation, authorization, sanitation, recordkeeping, or other required procedure.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Choosing an answer that protects convenience instead of client safety, public protection, or the stated professional duty.
Guardrail: Avoid answers that rely only on habit, ignore the stated source, skip safety or compliance steps, or choose convenience over the professional standard.
Memory anchors
Replacement Cost
Replacement cost estimates the cost to build an improvement with equivalent utility using current materials and standards.
Reproduction Cost
Reproduction cost estimates the cost to build an exact replica.
Direct Cost
Direct costs are labor and materials directly tied to construction.
Indirect Cost
Indirect costs include permits, fees, financing, professional services, and other non-direct construction costs.
Entrepreneurial Incentive
Entrepreneurial incentive reflects the reward needed to motivate development risk.
Physical Deterioration
Physical deterioration is value loss from wear, age, damage, or deferred maintenance.
Functional Obsolescence
Functional obsolescence is value loss from design, layout, utility, or feature inadequacy.
External Obsolescence
External obsolescence is value loss from outside the property, often incurable by the owner.
Age Life
Age-life depreciation estimates loss using effective age and total economic life.
Market Extraction
Market extraction derives depreciation or cost relationships from market sales.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
