I am the cosigner on a car loan, remaining balance is approx. 12k. The primary barrower has made continuous and prompt payments for the entire duration of the loan. My issue is this, I am purchasing a home. I have 2 other properties, and my debt to income ratio starting to become unbalanced, in the eyes of lending institutions. In order to improve my debt/income ratio i want to draw up an affidavit stating that the primary barrower is fully responsible for the remaining payments. How do this? any help is appreciated!
