This comment suggests a residential appraiser is opining on non-residential appraisals and doesn't truly understand the entire picture. While the residential real estate market is more (maybe mostly) driven by emotion, the commercial real estate market is more (maybe mostly) driven by money...cold, hard cash. Why would an investor in Timbuktu, seeking the highest return on his capital, care if a property is in Dayton, Cleveland, Philadelphia, or Atlanta if they conclude that they have reasonably equal prospects for achieving their investment goals in each? That is the fundamental power of a cap rate. While those engaged mostly in appraising residential real estate might conclude that if rents in Dayton were $10/ft² and were $15/ft² in Atlanta, a location adjustment is mandatory, an investor or competent appraiser can recognize that a cap rate of 10% in each case reflects equality.
I was the last one who thought a new office building being constructed in Sydney, Montana, in 2008 (population 4,778 after trending mostly down for 20 years, where locally relevant real estate was barely saleable) could relate to similar properties in Tennessee, Ohio, Utah, Oregon, Colorado, or North Dakota, but after actually doing the work (rather than ignorantly whining about what I didn't comprehend on a forum), it is inconceivable that a location adjustment was warranted between those properties and my subject. Cap rates were all between 7.1% and 9.3% and averaged about 7.8%, with Pembina, ND (population 579 and falling) being the outlier. Even more shocking is that all of these properties, mostly constructed for lease to US Government specs for US Government occupation, involved leases that allowed the tenant to cancel the lease with 30 days written notice. Again, doing the work led to a conclusion that investors in these properties did not view that as a risk because most were not aware of even a single instance where that had occurred.
As an aside, I see a lot of comments from "residential" appraisers about how deficient appraisals of any property type are when completed by "general certified" appraisers (and vice versa), and how any appraisals done by "designated" appraisers are inferior to any ever done by any appraiser lacking the motivation or acumen to become designated. These comments, viewed generously, suggest that these commentators, engaged in the business of analyzing and explaining variation in real estate prices, are fundamentally incapable of identifying extraneous data. Less generously, these commentators exhibit maturity equal to what I remember on the playground in about the third grade. Either way, such comments almost always paint the commentator as petty and jealous more than they detract from other licensees or designees.
