Which concept describes the permanency of land improvements and the investment required?

• A. Situs
• B. Modifications
• C. Scarcity
• D. Fixity of investment

Answer: (D)

Fixity of investment is the idea that land and its improvements require durable, long-term capital and stay in place for a long time. This means the money spent to build and improve a property isn’t easily redeployed elsewhere, and the improvements become a permanent part of the asset. That permanence influences how the property is valued, financed, and managed over time—the returns, risk, and cash flow are tied to that fixed investment. The other terms describe different ideas—location (situs), changes you can make (modifications), or limited supply (scarcity)—but none capture the enduring nature of the investment in land and its improvements like fixity of investment.
