1.2 Physical and Economic Characteristics of Real Property

Physical Characteristics of Land

Land has three physical characteristics that come from its nature, not from the market. Remember them with the acronym IIU.

• Immobility - the geographic location of land can never change. Soil may be moved, but the parcel's location is fixed. This is why real estate is governed by the law of the state where it sits.
• Indestructibility - land is durable and cannot be destroyed; it is permanent. This is why land itself does not depreciate for tax purposes (only the improvements on it do).
• Non-homogeneity (also called heterogeneity or uniqueness) - no two parcels are exactly alike because no two occupy the same location.

Land Does Not Depreciate

A consequence of indestructibility that the exam tests in appraisal and tax contexts: land itself does not depreciate. Only the improvements on the land lose value over time through physical wear, functional obsolescence, or external obsolescence.

Worked example: a property is valued at $500,000, of which the appraiser allocates $150,000 to the land and $350,000 to the building. For depreciation (a tax concept), only the $350,000 building is depreciated; the $150,000 land value is never written down. This is also why an owner cannot claim a depreciation deduction on a vacant lot held for investment.

Why the Physical Traits Matter on the Exam

Each physical trait drives a tested consequence:

Trap: because every parcel is unique, money damages may not make a wronged buyer whole, so courts can order specific performance (forcing the actual sale) rather than just awarding cash.

Economic Characteristics of Land

Land has four economic characteristics rooted in markets and human activity. Remember them with SIPA (Scarcity, Improvements, Permanence, Area preference):

• Scarcity - the supply of land is finite. Even where land seems plentiful, well-located land is limited, which supports value.
• Improvements - a man-made addition (a building, road, or utility line) affects the value of that parcel and surrounding parcels.
• Permanence of investment (also called fixity) - improvements represent a large, long-term, largely irreversible capital commitment, which is why mortgage financing runs for decades.
• Area preference (also called situs) - people's preference for a particular location.

Situs: The King of Value

Situs (area preference) is the single most important economic characteristic in determining value. It explains the cliche "location, location, location." Two physically identical houses can sell for vastly different prices solely because of where they sit.

Worked example: an identical 1,800-square-foot house sells for $300,000 in a desirable school district but only $210,000 three miles away in a less-desired area. The $90,000 spread is pure situs - nothing about the structure changed, only its location preference.

Bundle of Rights and Highest and Best Use

Ownership conveys a bundle of rights, often remembered as PEPED: Possession, Enjoyment (peaceful use), Prevention (control), Exclusion (keep others out), and Disposition (sell, will, or transfer).

Highest and best use is the legally permitted, physically possible, financially feasible, and maximally productive use of a parcel. All four conditions must be met. A vacant downtown lot zoned for retail may have a highest and best use as a coffee shop even though a single-family home is physically possible - because retail is more productive there.

Supply, Demand, and the Effect of the Physical Traits

The physical and economic traits combine to make real estate markets behave differently from markets for ordinary goods:

• Slow supply response - because improvements are permanent and land is fixed in location, new supply takes years to build, so prices can spike before supply catches up.
• Local markets - immobility means a national average is nearly useless; value is set by the local supply-and-demand balance at the property's situs.
• Illiquidity - uniqueness and large value mean a parcel cannot be sold instantly at a posted price like a share of stock; finding the right buyer takes time.

Trap: the exam may ask why real estate is considered an illiquid investment - the answer ties back to non-homogeneity (each parcel is unique) and the time it takes to match a unique parcel with a willing buyer.

Water Rights Are Part of the Land

Because land includes natural attachments, the exam tests how water rights pass with ownership:

• Riparian rights attach to land along a flowing waterway (river or stream). If the water is navigable, the owner typically owns to the water's edge; if non-navigable, often to the center.
• Littoral rights attach to land bordering a stationary body (a lake, sea, or ocean); the owner generally owns to the average high-water mark.
• Prior appropriation, used in many arid western states, separates water rights from land ownership and grants them by permit on a first-in-time basis ("first in use, first in right").

Trap: the words riparian (flowing) versus littoral (still) are a classic swap; tie riparian to river.

Matching Traits to Tested Outcomes

Lock in the difference between the two groups: physical traits describe the land itself, while economic traits describe its market behavior.

A frequent trap mixes the two: improvements is an economic characteristic even though it sounds physical, and uniqueness (non-homogeneity) is a physical characteristic even though it influences value. Sort each term into the correct column before answering.
