Okay, I just ran MLS sales and within two minutes found two townhome sales that closed in February and March in the $230-250 per foot range, but these are 2100 and 2600 sf town homes built in 2023. Without knowing specifics about your property it is hard to judge somebody else's appraisal. These two sales were three story town homes with roof top decks. I don't know if these town homes are superior to yours or not.
I would suggest changing lenders and getting a new appraisal. But, without knowing much about your property it does not guarantee the other appraisal is not correct. As far as entertainment district and short term rentals go, those are dicey subject's. That is why it is best to use sales from the immediate area. That is why your agent should have provided town home sales from the immediate area and never mentioned 1960's single family homes.
If you use a lender that uses AMCs it is very possible they may use the cheapest appraiser they can find which may mean a good appraiser or it may not. Stick with local banks and avoid the Rocket Mortgages of the world.
