Shannon: The process is basically an appraisal of a lease fee interest, which would fall under the classification of a complex appraisal assignment in my humble opinion, thus requiring a general certified appraisal license. Given the number of cell towers, or any kind of tower for that matter in any given market, the volume of potential business and simplicity of the appraisal process would seem to indicate that it would not be a very profitable business for an appraiser. Once you know the yield rate, it is a simple matter of summarizing the lease, putting the cash flows on a spreadsheet, entering the formula, and hitting the enter key. You really would not have to inspect the property because you are appraising the lease. One person could probably handle the business for an entire region. When you have interest rates jumping around 4% in six months, the stock market acting like a roller coaster, and energy cost going in every which direction, commercial appraising is becoming a general crap shoot anyway. About all we can do is draw a box and say: “The answer will most likely be somewhere inside that box depending on the prevailing interest rate level, expense trends, and market yield rates at a particular point in time.”
