FHA H&b Use Analysis

[CANative]

That doesn't preclude the current use meeting the four tests and being the best use.
There's a reason H&B use analysis is on page 1. It determines what you will use for comps, so of course it has to come before the sales approach.

I have a small H&B use paragraph that covers about 99% of the appraisals I do. I may have purloined it off someone here at AF ...

HIGHEST & BEST USE: The subject is a legally permissible use allowed under current zoning. The lot size, shape and utility allow for the present improvements, and based on current market conditions, the existing improvements are the most economically feasible and productive use of the property. If vacant, the highest and best use would be to construct a single family dwelling.

I posted a copy and paste of one of comments from an appraisal basically saying the same thing. The post you quoted was just one example among many possible situations.
