Is HP 12C Calc guide wrong?

I am working on mastering the HP12C before I dive into study mode. Going through HP Practice problems and the one below is confusing me. The HP Guide says the Lender NPV of cash advanced is -$13,615.02. I would think its $13,615.02, as IRR is 14.83%. When i solved i was getting positive $13,615.02 and 14.83% IRR. Is HP guide correct, since its NPV of Net cash advanced, or Am i correct and i should ignore this HP problem and just dive into the studying. Thanks!


An investment property has an existing mortgage which originated 8 years ago with an original term of 25 years, fully amortized in level monthly payments at 6.5% interest. The current balance is $133,190.

Although the going current market interest rate is 11.5%, the lender has agreed to refinance the property with a $200,000, 17 year, level-monthly-payment loan at 9.5% interest.

What are the NPV and effective yield to the lender on the net amount of cash actually advanced?
