Highest and best use of a property

[Todd Fullerlove]

Helll BP world,

I'm under contract in Texas for a duplex to house hack. My lender told me that the appraisal needs to come back as highest and best use is a single family residential home. If he comes back the highest and best use if an investment property, I cannot use an FHA loan. Does anyone have any experience with this? I know it's possible to use FHA for a duplex. I feel like the best use is a single family because it's a single family home technically.
