Q: David: I applied for a mortgage and got turned down because I didn't have enough income for the house I wanted. My loan officer suggested that I take out a part-time job to get me over the hump. I did get a part-time job but now the lender says they won't accept the part-time income after all. Who's right? The lender or the loan officer?

A: The lender. Unless you can show a two-year history of part-time employment a lender most likely won't use it. When a lender evaluates your loan application they want some sense of certainty your new part-time income is likely to continue well into the future to help you pay the mortgage. Without a history of part-time income, the lender won't be convinced of your intentions to work two jobs.
