Mixed Use Property Comps???

[Gabe S.]

Wondering if anyone had any insights on running apt / office mixed use comps.  Its in a residential area. Property is a single apt and an office (suitable for small law firm, cpa, etc). Trying to wholesale it but coming up with comps is above my proverbial pay grade.  There are only a few fairly recent transactions in the immediate area which are SFHs and even those have a wide spread.

Any realtors or appraisers have suggestions?
