They are. However, because of the nature of temporary work, these people need to work a bit harder to be approved for car loans. Because their income and employment are uncertain, they are perceived to be a greater risk.
Some concrete steps that can be taken to mitigate the perceived risk include:
Obtaining an offer letter from an employer. An offer letter for a future permanent position is obviously best, but an offer of a long-term contract is helpful, too. The lender wants to see that you will have employment (and the income that goes with it) for the life of the loan.
Staying with your employer. An extension of an existing contract indicates greater employment stability, even if the job has a planned end date. Lenders assume that further extensions are more likely. There’s also the possibility of an offer of permanent employment.
Getting a cosigner. A cosigner with stable income and employment can mitigate the risk presented by a temporary worker. The cosigner must be aware that they will assume responsibility for the loan should the primary borrower be unable to make the payments.
As the U.S. economy moves toward more temporary employment, look for lenders to offer programs that are more suited to the growing population of contractors, temps, and seasonal and casual workers.
