Would banks allow my PML to co-sign on a cash-out-refi?

[Jordyn Gegg]

Weird question, but lets say in a future BRRRR deal I have a PML fund the entirety of the acquisition + rehab. Now that the property is fixed up and appraised for a higher price, I go to a bank to pull my equity out of the deal and repay the PML + interest via a cash-out-refi.

Question: Would the bank allow my PML to co-sign on the refinance if I am using the money to repay them?

If you're wondering why I would try to do such an odd thing, I'm 20 and don't have a nearly attractive financial profile to banks by myself, so I am considering having my parents act as the PML in this situation.
