I currently have two private loans owned by US Bank and serviced by Firstmark. One of the loans has a co-signer whom I would rather not fuck over, the other does not.

If I pay the minimum payment, it is allocated between the two loans. I do have the option to pay each loan separately, in other words, through the Firstmark site, I am able to choose the amount I want to pay to each loan. Each loan has a minimum payment amount, but the site does allow to make a payment to one loan and not the other.

I would like to pay the loan off that I have a co-signer on, as I could likely pay it off in two years if I allocate the full payment to the co-signed loan. I’m willing to default on the loan that is solely my responsibility, I just don’t know how this might play out.

Has anyone successfully attempted something like this? If I pay on only one loan, I imagine I’ll start getting letters and phone calls about it, but will they also attempt to contact my co-signer for the second loan? Previously if I’ve ever missed a payment on both loans, my co-signer has received a letter for only the loan that they have co-signed on.
