One important thing to remember is that the answer to your question may depend on various factors. Experienced appraisers in this thread have provided valuable feedback regarding this matter. When I bid on a potential job, assumptions are often made about the property characteristics, only to find something unexpected once on-site, which can be frustrating. This is just the nature of the business.
As I was reading your original post, I couldn't help but notice something concerning. It's been an ongoing issue for me when a residential appraiser determines the highest and best use of a gray area residential property as commercial use, which is generally outside the scope of their licensure. I'm curious about where the appraiser got their market knowledge and expertise to make this determination. It seems odd that a determination would be made on a property the appraiser is not licensed to appraise. However, having a commercial license doesn't automatically make one more qualified than someone without it. In either case, making such a determination requires experience or the ability to gain that experience. I suspect the initial appraiser used the excuse of calling it commercial use to avoid telling their client they didn't know how to appraise it. However, it is possible they did know how to appraise it, and their determination ended up being correct.
A narrative report doesn't necessarily provide more credibility than a typical form report. Both reports require the same level of communication from the appraiser, and there is no information in the narrative that shouldn't be in the form. However, if commercial property is put on a residential-designed form, it could lead to a misleading report because of the hard print references throughout the form. Those of us who prefer narrative reports find that it gives us better control over the format and flow of communication. But it doesn't make it a better report than using a form or offering a different answer.
Please do not dismiss Terrel's opinion simply because it may differ. You are lucky to have someone with significant experience who can advise on property types like yours. Terrel has a solid foundation to help you solve the problem. However, an element of guesswork is involved since we are unfamiliar with your market. Every market has unique characteristics specific to its location and the people who make it up. We all provide advice based on limited information, which could easily change as we discover more value-related factors.
You are facing two main challenges right now. Firstly, Appraisal Management Companies (AMCs) usually prioritize the cheapest service available, which can result in hiring less skilled appraisers who may not have the necessary experience. Unfortunately, a low fee can discourage experienced appraisers from accepting the assignment. Sometimes, you do get what you pay for. The payment offered for your complex assignment is minimal and falls within the approved Veterans Administration $600 threshold for non-complex typical properties. Why would an experienced appraiser take on a challenging assignment like yours for a fee that is offered for less complicated assignments? Most of us don't have Terrel's typing skills and find the couple of days of work needed to complete your job unappealing. In this case, your issues are likely fee-related, whether you like it or not.
Secondly, determining whether a property is for commercial or residential use requires extensive market research and knowledge, and quick on-the-spot answers lack foundation and are generally not an acceptable practice, especially with complex or unusual properties. The highest and best use is the foundation for building a credible report. We don’t have the secret book of answers or a crystal ball that directs us. It takes time and commitment to do it right. If I were lucky and had data to fall back on, this is still a couple of days' job. It could easily be more if the market supports commercial use.
I don't believe that a Certified General and narrative report alone can solve your problem. The next step is to find an appraiser, whether residential or commercial, who has market knowledge. This may not fit into the selection process of the AMC and lender, but this is where you come in. It would be best to tell your client that fee shopping is not in anyone’s best interest. Instead, inform them that you want the correct answer and would be willing to offer fair compensation to obtain it. Otherwise, no answer in this thread will solve the underlying issue.
Terrel, I enrolled in Udemy's Master Typing class. I clearly need to improve my skills.
