@Chris Marette, take this with a grain of salt, because the only times I appealed appraisals were before COVID.
In my experience, if you stay with the same lender and you get a second appraisal, the best I got was an average of the two appraisals. Your lender may be different and I would confirm how they will handle, since they already have one appraisal in hand.
If you do go second appraisal, I would be sure to supply both the appraiser AND the lender a copy of your current lease. And I always make my own appraisal packages: comps that I best feel match my property, including pros and cons of each, and a complete list of improvements I have performed.
I also always meet the appraiser at the property to hand deliver package, and make myself available for questions. I use this to sort of "sell the area". You can't be pushy, because some appraisers are grateful that you are basically doing their work for them, and others think they know better, so you need to stay in the background with the latter.
All that being said, I have heard from several of my realtor friends lately that they are seeing far more issues with appraisals coming in short. At the end of the day, the appraiser's biases will be reflected in their report, even though they are not supposed to. If they think property values will be crashing soon and we will be in a recession, they will come in lower. If they have an optimistic view of your property and neighborhood, they will likely come in higher. If they like your choice of finishes, they will use higher end properties as comps. If they think it is ugly, they will use lower end comps in the area.
