The foundations of appraisal were based upon three independent approaches to value. A system, when developed correctly, presents a check and balance within the report. The idea being that when an appraiser takes the time to develop each report, the data will show three independent motivations and three separate value conclusions. Nonetheless, the conclusions will support one another because the underlying principle for each approach is the principal of substitution.
For the purposes of valuation or real estate appraisal, the principle of substitution is defined by practical application. Simply the idea that a prospective purchaser will pay no more for a property than the cost of acquisition of an equally desirable substitute having equal utility and acquired within an equal amount of time. This principle is accurately assumed to be the underlying principle of the direct sales comparison; however, it should be recognized that the principal of substitution is also the underlying principal for the cost approach was well.
The cost approach, when completed in a serious and professional way, is not only crucial to the appraisal of residential real estate, but also crucial for an underwriter to properly understand other factors that influence the value of the subject. Additional principles that are in play within each real estate market, but few people take the time to identify these factors or understand their effects. A few of these principals will be listed below, in an attempt to help the average user of an appraisal gain a deeper appreciation for the thought process that goes into each appraisal report.
The Principals of Anticipation, Balance, Change, Conformity, Contribution, Progression, and of course Substitution are the basic tools of analysis that go into the professional analysis of each report.
Anticipation is the underlying fountain of the Income Approach to Value, but it also reflects the motivations of prospective purchasers of residential properties and has a foundational effect within the Direct Sales Comparison Approach as well. The income approach is of course a reflection of the present worth of anticipated income. The Direct Sales Comparison (or Market Approach) reflects what competing purchasers are willing to pay for the anticipated benefits that are attributed to a particular property, or characteristic, like quality, appeal, or location. These motivations are carefully considered when understanding a property and how it relates to its market.
Balance recognizes that the value of a property reaches its greatest potential when the four agents of production achieve the state of equilibrium. The four agents, being labor, management, capital, and land. When these agents are out of balance (in residential properties) you see a loss of value due to an over or under-improvement to the land. This principal comes into play when determining the proper highest and best use and remaining economic life. All three approaches to value are affected by the Principal of Balance.
Change is inevitable – except from a vending machine. ~Robert C. Gallagher, but I digress. Change is continual therefore an appraisal is only reliable as of the date of value. The very next day, a plant could open in the town that would employe 1,000 workers increasing the purchasing power of the community and creating a demand for immediate housing, or the opposite could happen as well. Nothing ever remains the same in this world, this is a principle that affects all things not just real estate appraisal. It is this principle that lenders today are very concerned about as they are wanting appraisers to decipher the market conditions and decide which stage of change the marketplace is in (i.e. growth, stability, or decline).
Conformity states that maximum value is generally realized when there is a reasonable degree of neighborhood homogeneity. That is to say social and economic characteristics should be harmonious, deed restrictions and/or land uses compatible and property types reflective of these factors. Generally speaking the elements of conformity are not planned, but are borne out by the market forces that shape a community over time. Successful neighborhoods that thrive and enjoy stable or increasing values are communities that have developed amenities that are supportive of the overall needs and expectations of that community.
Contribution reflects the market reaction to a physical improvement of a property, not its cost. The best and well-known example is a swimming pool that today can easily cost $50,000 to $85,000 for a pool with a heater, and filtration system, and spa, and water fall, and all the “accoutrements” relevant to the enjoyment of a swimming pool. But the market generally resists the real cost of such improvements. The amount the market is actually willing to pay is known as the contribution value, of course the loss of value (or buyers resistance) should be shown as functional depreciation, but that is for a different discussion.
Progression, this principle is a politically correct way to discuss the basis for external depreciation and reflects the marketplace today with many REO properties on the market. This principal teaches that when properties of similar quality are adjacent or associated within a particular market area, the inferior properties will benefit from the association of the superior properties. That is to say you have an equal number of inferior and superior homes, the prices of the superior homes can benefit the inferior homes. The inverse is also true. The prices of the superior homes will regress due to this association.
When these principles are understood, employed and correctly analyzed the appraiser is then able to give insight not only to “the three best comparables” but why the market behaves in the way that it does and an appraiser can then anticipate future expectations making certain assumptions about performance based upon previous trends and reactions.
Unfortunately, this material was not sexy, or alluring, but I hope that those underwriters, operations managers, lenders, regulators or even appraisers who may not have had the best training will find some benefit in the information that I have provided above. It is critical for all to you know, understand and acknowledge. Nothing I have presented in this blog, is an original thought and I take no credit for the thoughts or analysis.
I have drawn from several years of study and instruction to give this summary of some of the foundational basics of appraisal to enable the users of our reports a brief insight and hopefully, new-found appreciation of the thought and time involved in the production of a real estate appraisal.
See you around the water cooler!
