1.2 Physical and Economic Characteristics of Real Property

Why Characteristics Matter

Land behaves differently from any other asset, and the exam expects you to connect each characteristic to a legal or economic consequence. There are three physical characteristics (intrinsic to the land itself) and four economic characteristics (about land in the marketplace).

The Three Physical Characteristics

Memorize them as I-I-U:

Indestructibility trap: Land itself is permanent, so for appraisal and tax depreciation, only the improvements (buildings) depreciate — never the land. A question asking what portion of a property an investor may depreciate excludes land value.

Worked Example: Depreciation Excludes Land

An investor buys a small rental property for $300,000. An appraisal allocates $90,000 to land and $210,000 to the building. For tax depreciation, only the building is depreciable. Using a 27.5-year residential schedule:

• Depreciable basis = $210,000 (land is excluded)
• Annual straight-line depreciation = $210,000 ÷ 27.5 = $7,636.36 per year

If a test taker mistakenly depreciates the full $300,000, the answer ($10,909/yr) will be wrong. The indestructibility of land is the reason: land does not wear out, so it cannot be depreciated.

The Four Economic Characteristics

Memorize them as S-I-P-A (Scarcity, Improvements, Permanence of investment, Area preference):

• Scarcity — Supply at a given desirable location is limited. Scarcity supports value: scarce, desirable locations command premiums.
• Improvements — A building or new infrastructure changes land value and the surrounding area. A new highway interchange can raise nearby land values dramatically.
• Permanence of investment (fixity) — Capital invested in real estate (utilities, roads, structures) is fixed and long-lived, so returns are realized over a long horizon.
• Area preference (situs) — The people-based preference for one location over another. Situs is frequently the single strongest value factor.

Because invested capital is fixed in place, real estate is a long-term, relatively illiquid investment compared with stocks or bonds. An investor cannot relocate a poorly placed building, which is why due diligence on situs before purchase is so important — the location decision is permanent and dominates long-run value.

Distinguishing Scarcity from Situs

Students confuse these. Scarcity is about supply — how little of a desirable thing exists. Situs (area preference) is about demand-side preference — why people want a particular spot (schools, views, commute, prestige).

Exam tip: If a question emphasizes why people want a location, the answer is situs/area preference, even when supply is also limited.

Connecting Characteristics to Exam Answers

The single most common error on this topic is treating the seven characteristics as memorization-only. Examiners instead test the consequence of each one. Use this decision chain when a question describes a scenario:

• A court orders the seller to convey the exact parcel -> uniqueness (no substitute exists).
• Property is taxed or sued where it physically sits -> immobility.
• Only the building depreciates, not the dirt -> indestructibility.
• Buyers pay a premium because people want that spot -> situs (area preference).
• Supply of a desirable location is limited -> scarcity.
• A new road or utility changes nearby value -> improvements.
• Capital is fixed for the long run and illiquid -> permanence of investment.

Notice that immobility and situs are easy to confuse: immobility is a physical fact (you cannot move the land), while situs is a demand preference (people choose to be there). A question framed around taxation or jurisdiction points to immobility; a question framed around buyer desire points to situs.

Worked Example: Improvements Versus Permanence

A developer spends $1,200,000 installing roads, water lines, and sewer on raw acreage, then divides it into 24 finished lots. Two characteristics are in play and the exam may ask you to separate them.

• The physical work itself (roads, utilities) is an improvement that raises land value.
• The fact that this $1,200,000 is sunk into the ground and cannot be relocated or quickly recovered is permanence of investment (fixity).

If each finished lot sells for $95,000, gross revenue is 24 x $95,000 = $2,280,000. Subtract the $1,200,000 improvement cost and the raw-land cost; the spread is the developer's margin. The point for the exam: the improvement created value, but permanence of investment explains why the developer must be confident in situs before committing - that capital cannot be pulled back out if demand disappears.

Quick Drill: Match the Clue to the Characteristic

Use these one-line triggers as a final review. Each is the exact phrasing examiners favor:

• "Cannot be moved; taxed and sued where it sits" -> immobility (physical).
• "Land does not wear out; only buildings depreciate" -> indestructibility (physical).
• "No two parcels alike; supports specific performance" -> uniqueness/nonhomogeneity (physical).
• "Limited supply of a desirable location" -> scarcity (economic).
• "A new road or utility changed nearby value" -> improvements (economic).
• "Capital is fixed long-term; illiquid investment" -> permanence of investment (economic).
• "People prefer this spot; strongest value factor" -> area preference/situs (economic).

Remember the count: three physical, four economic. If a question asks which is not physical, eliminate immobility, indestructibility, and uniqueness; everything else is economic.
