I received a call yesterday from a homeowner who had just acquired an appraisal from another appraiser. She was upset that the appraiser had not made any value adjustment
for her new and very expensive owned (not leased) photovoltaic (PV) solar system. When she contacted the appraiser to ask why, in her words, the appraiser said,
“There are no comparable sales, so I cannot give it any value.”
This statement bothers me and should be troubling to other professional appraisers. I understand that this is a secondhand quote and that the homeowner may have gotten
it wrong, but I have heard similar words from other appraisers before. Let’s assume, for the sake of this article, that the quote is accurate.
appraisers do not give value;
appraisers estimate value. This is an important distinction to understand. An appraiser giving value sounds just as silly to me as a meteorologist who says he/she will give us rain tomorrow. Just as weather forecasters do not give rain, appraisers do not
With that said, it would be appropriate for the appraiser with no PV comparables to study the market and conclude that the market is not willing to pay anything additional
for the PV system. However, just as a statement of value requires evidence, a statement that there is no value also requires verification. In this case, there is already evidence of at least some cost value in the PV system and a diligent appraiser would
need to have additional evidence, or at minimum sound logic to the contrary.
Appraisers have three approaches to estimate value for any given property or feature- the sales comparison approach, the cost approach, and the income approach. If the
appraiser finds no comparable sales (common with owned PV), and has ruled out looking a greater distance from the subject or further back in time, then the appraiser could look to the cost approach and the income approach for other evidence of value.
The cost of a PV system, minus government subsidies, is an indicator of value for the system. Cost does not always equal value because profit could be built into the
market (entrepreneurial incentive), or there could be depreciation from wear and tear or reduced functionality. Street appeal could be a factor with PV systems given that some people do not like the looks of PV systems and some people love the look. I think
it depends on the house and the acceptance in the location. Modern homes in the “Green Hip” city of Portland, Oregon are a good fit, but a Victorian in Portland’s suburbs might not be. Regardless of the outcome, the appraiser could analyze the cost and depreciation
of the PV system to help estimate value.
The present dollar value of future income from the energy savings is also an indicator of value for the PV system. An easy way to calculate this is by accessing
pvvalue.com. Income does not always translate
to value, particularly on a property that is purchased by someone who is not looking for income. However, there is evidence from several published studies that energy savings do translate to at least some increased home value, just that it may not be on a
dollar per dollar basis. Regardless of the outcome, the appraiser could analyze the potential income from the PV system to help estimate value.
When there are no comparable sales, the appraiser still has a professional obligation to analyze value. The mere lack of comparable sales does not mean a corresponding
lack of value. No comparable sales simply indicate that there is less evidence for the appraiser to estimate value and consequently, the appraiser’s estimate might be more subjective.
