How best to challenge a low appraisal

[Jeffrey Schratz]

I just completed a BRRRR, having invested a total of $150,000. I had estimated that it would appraise for $200,000-$250,000. The appraisal came in really low, ($132,000). In reviewing the appraisal, the comps average about $175,000. Its a 4 unit, with two units already rented at $800 and $900 at the time of the appraisal. The appraiser estimated the other 2 units to rent at $700 each, but the just rented for $925 and $975. How do I best approach the bank and/or appraiser to try and get a higher appraised value.

Thanks for any thoughts.
