Appraisal comps on home with non permitted bathroom...3/2 or 3/1?

[Brennen McConnell]

I am rehabbing a home as a BRRRR that is listed as a 3/1 on the county website, but when I bought it, there was a non-permitted half bath on the second floor. If I turn the non permitted half bath into a full bath, will the appraiser use other 3/2s as comps when appraising the value of the home for the refinance? Or will they have to use other 3/1s as comps since the home is listed as a 3/1 on the county website? I would imagine if selling the home, it would have to be listed as a 3/1 unless we pulled permits on the 2nd bathroom, but am wondering if it would be counted as a 3/2 on the appraisal.
