My original unpaid principal balance is {$150000.00} but my current unpaid principal balance is {$150000.00}. My loan is current and i have never missed a payment i dont understand how my balance could be going up unless i have a negatively amortizing loan which i do not. I have a FHA loan with a fixed rate of 4.2 %. The servicer is pennymac and the loan number is XXXX and they have been non responsive to my inquiries on this. I am very concerned.
