3 Real Estate Valuation

What real estate valuation estimates

Real estate valuation estimates the value of a defined property interest as of a specific date. The conclusion depends on what property interest is being valued, the intended use of the estimate, relevant legal rights and restrictions, and market conditions on that date. An Appraisal is an informed opinion supported by property and market evidence, not a guarantee of a later sale price.

Several principles guide the analysis. Substitution means a buyer generally will not pay more for a property than the cost of acquiring a comparable alternative with similar utility. Contribution means a feature's value depends on how much it contributes to the property's value, not simply what it cost to install.

Highest and best use is the reasonably probable use that is legally permissible, physically possible, financially feasible, and most productive. It helps determine which properties and uses are relevant to the analysis. Reliable conclusions also depend on relevant market evidence, appropriate adjustments, and a clear explanation of the reasoning.

The appraiser considers the property's location, site, improvements, condition, permitted uses, and relevant market before selecting the approaches that best fit the property and assignment.

Comparing property sales

The Sales comparison approach estimates value by comparing the subject property with similar properties that have sold. It is especially useful when enough recent, reliable sales of comparable properties are available, and it is commonly used for homes and vacant land.

The appraiser selects Comparables—properties similar in location, property type, size, condition, and use—and adjusts their sale prices for meaningful differences. Adjustments are made to the comparable sale, not to the subject property. If a comparable is inferior to the subject in a feature buyers value, its price is adjusted upward; if it is superior, its price is adjusted downward.

Relevant differences can include the sale date, financing or sale conditions, location, lot size, building area, condition, and amenities. The appraiser weighs the adjusted evidence rather than treating every comparable as equally persuasive.

For example, a comparable home sold for $400{,}000 and has a renovated kitchen that the subject lacks. If market evidence supports a $15{,}000 adjustment for that difference, the comparable's adjusted indication is $385{,}000. Other comparable sales are adjusted in the same way and together help support a value range and conclusion.

This approach can be less reliable when sales are scarce, properties differ substantially, or market conditions are changing quickly.

Valuing expected property income

The Income capitalization approach estimates what an investor might pay for a property's expected income. It is most useful for rental and other income-producing properties. The analysis projects income, accounts for vacancy and collection losses and operating expenses, and converts the resulting income or cash flows into a value indication. Projections and rates should be supported by market evidence.

A common simplified method is direct capitalization:

Net operating income (NOI) is property income after vacancy and operating expenses but before debt payments. The Capitalization rate, also called the cap rate, expresses the relationship between a property's NOI and its value and reflects the return investors require for properties with comparable risks.

For example, if stabilized annual NOI is $72{,}000 and a market-supported cap rate is $6\%$, the indicated value is:

For a property whose income is expected to change over time, Discounted cash-flow analysis estimates the present value of projected cash flows and anticipated sale proceeds at the end of the holding period. Value is sensitive to assumptions about rents, expenses, vacancy, resale proceeds, and discount rates, so those assumptions require support.

Estimating land and improvement value

The Cost approach estimates land value plus the current cost of constructing improvements, less depreciation. It is often useful for new or special-purpose properties, or when comparable sales and income evidence are limited. It can also provide a useful check against other approaches.

Replacement cost is the cost to build a structure with similar utility using current materials and methods. Reproduction cost is the cost to create a close replica using similar materials and design.

Depreciation can reflect different sources of loss in value:

• Physical deterioration reflects wear and damage.

• Functional obsolescence reflects shortcomings in design or utility, such as an inefficient layout.

• External (economic) obsolescence reflects influences outside the property, such as an unfavorable change in the surrounding area.

For example, if land is estimated at $300{,}000, current replacement cost is $900{,}000, and total depreciation is $250{,}000, the cost approach indicates $950{,}000. This is an estimate, not necessarily the market price, because construction cost and buyer demand may differ.

Reconciling indications into a value opinion

The three approaches produce separate value indications, not answers that must be averaged. In Reconciliation, the appraiser considers each method's relevance to the property, the quality and quantity of its data, and the reliability of its result.

A well-supported sales comparison indication may carry greater weight for a typical home with plentiful comparable sales, while income evidence may be more informative for an apartment building. The appraiser explains the final conclusion and why particular approaches were included or omitted.

Real estate value is therefore an evidence-based estimate tied to a particular property interest and date. Sales comparison uses adjusted sale prices of similar properties, the income approach converts expected property income into value, and the cost approach adds land value to improvement cost less depreciation. The methods are selected and reconciled to fit the property and available evidence rather than automatically averaged.
