I would be happy to look at the specific address and give you my opinion, however typically I try to stay away from flood zones unless the property has a high elevation. 

They may have advance notice of re-maping.You may want to check the proximity of the property to the nearest High Hazard zone and the difference in elevation. 

We are circling a number of properties and want to find the right partner before we close.We have a bit of a unique situation and would love input from the BP community.My wife is an architect (formerly at Gensler) and is providing all of the design and elevations + floor plans.We are researching feasibility consultants and structural engineers in the LA area who specialize in ADUs and would love any vetted recommendations.

We looked at condos that has been sold on the same complex that are similar to what we are trying to accomplish elevated a little to differentiate from competition.

Unfortunately, I don't think Idaho has many STR companies, but I learned about Daugherty Management during Breezeways Elevate Conference this year.

My guess is you are dealing with counter review staff, but your engineer needs to elevate this to senior staff who can make an alternative decision.

Do elevated interiors matter?

I like to think of it as a "wealth elevator."

In my opinion, one of the great things about STR is that there is a wide range of accommodations, in a wide geographical area, with differences in property condition, size, location, cleanliness, amenities, etc.  85% of motels/hotels are basically the same, the major differences in many of the lodgings newly built seem to be the number of bars of soap offered in the bathrooms, and whether the property is served by two elevators or three.  

I did this in Phoenix for a nice little 3x appreciation rocket ride between 2009-2016, so I'm not knocking it, but I definitely sold out in 2016 (a bit early in retrospect, but better a bit too early than too late) to avoid riding the elevator back down to the basement.Global bottoms are much much more difficult to call ... they are exceedingly rare ...
