Joint Credit

See: Joint Bond.

When you're looking for a loan, potential lenders will look at your income and credit score, along with whatever assets you have. They're trying to figure out your individual ability to repay the debt on time.

Joint credit allows you to pool resources with someone else.

You and a buddy are looking to open a margarita stand on the beach. In shopping around for joint credit, lenders will look at your combined incomes and take both your credit scores into account. Meanwhile, they will judge the combined total of both your asset holdings to compute the likelihood that you'll be able to repay the loan together.
