Don’t tell them what your plan with it afterwards is. Just say you want to buy it out and you got financing approved through your local CU. See what they say.
Also, see what options are shown for your buyout on their website.
Transferring a lease is a separate thing from a buyout, dealers usually don’t know about it - but it’s useless for you as usbank doesn’t allow it during the last 13 months of a lease.
They will let you pay cash. Plus tax your remaining payments and $8-900 early termination fee! Just found that one out too. That’s not in my contract. But I think they can do what they want. As long as it’s not in the contract that says no early buy out fee or something.
