An appraiser can testify as to the before and after values, assuming you can tell him what was done. 

I have a great lender locally that is a pleasure to work with, but ran into a situation recently that involved an unfavorable appraisal.

Would that also mean that the bank's appraisal for a mortgage would be way above actual value?

Yes several investors offer fixed second loan and heloc programs including one 100% online with no appraisal required, disbursement in 5-7 days. 

Contingencies for fourplex properties include inspection, financing, appraisal, rental income, and pest inspection.

In its current condition, I believe it would appraise for 160-170 and after updating the house cosmetically, probably 180 or more if I had to guess.

The seller was a foreign landlord who was behind on a few years of taxes, and the property was in C5 condition at the time of initial appraisal.

If you want to keep the property as a rental, you can pull cash out on the new appraised value with a DSCR refinance loan if it's been 3 months since when you last purchased or financed.
