Low appraisal on a refinance

[Alec Frasier]

im currently trying to Refi a duplex I had purchased for 152k, appraisal was ordered and came back at Purchase price (152k) I'm certain the duplex is worth and will sell for 175k in its current market no problem. the problem is I'm using a PML with a 145k balance left on the duplex which puts it at 95% of its said value. Im looking for solutions or tips with moving forward with this problem. We are trying to rebuttal the appraisal and I would hate to sell because after appraisal it'll cashflow great. looking for tips or referrals in the event the appraisal doesn't go as planned.
