As otherâ€™s have already written, there are no real upsides in being a co-signer on someone elseâ€™s loan. By co-signing you assume equal and full responsibility for this loan and your ability to get a future loan will be impacted. Should the person youâ€™re helping default on the loan, you will be held responsible. I would think about this seriously, itâ€™s not something you should enter into lightly. If the person youâ€™re helping could be helped with a gift of money towards their down payment, this is something you may want to consider. If the person needs your credit score or asset strength to qualify for the loan, I would suggest they buckle down and work on improving their own credit score and paying down their debts.
Best of luck to you
