Thanks for the replies.

I got the appraisal packet dropped off for review. Unfortunately, the appraisal was for the building only and not for the HUGE inventory.

Son is 24 and didn't know to do inventory at the end of 2022. Nor did anyone after dad passed away.

To top it off, the record keeping is on paper and inadequate...

I feel like FMV of used items is what they are sold for. So only new purchases (& pawn forfeits) would have a possible profit for the year.
