<prompt> Human: The mortgage numbers:maturity date: 10012043principle remaining: 255kAPR: 3.875current monthly amt toward prinicple: 481 current monthly amt toward PMI: 137 PMI auto-removal date: Sept 2019 22 months awayI had the mortgage company do a broker price opinion BPO on the house to see if I have a good enough LTV ratio to remove the PMI before the auto-removal date. It came back that I need to reduce the principle by 15k to do so. My question is, is it worth it?136month 22 months 3000 20 of my 15k over 2 years And Ill be saving the 3.875 on the 15k each year moving forward and Ill rapidly accelerate by amortization schedule.The real estate market is Southern NH, USA, in a desirable townschool district. We plan on being in the house for another 10 years.Thanks for your help again, PF!  <response>: Youd be getting an immediate return of almost 11 on that 15k, just for the PMI savings. Add the mortgage interest youll save and youre looking at an almost 15 return on that money. I think thats a no-brainer.
