I have been searching but cannot find the answer to a current situation:
Buyer is full time employee over 2 years on primary job as mechanic. Permanent full time good income. Buyer has second job as mechanic, permanent 30+ hours a week.
I am being told that this income cannot count because this employer relationship has been less than 2 years. Is this correct? I always believed that since it is same line of work, it should be considered. I have searched for underwriting guidelines for income and have not found a clear answer. Please help or PM me.

FHA guidelines have always been 2 years on a second/part time job in order to include that income.

Same line of work is not a good argument.
FHA wants to know that the borrower can sustain the working hours. Therefore, if they can do it for 2yrs.... FHA will allow.

Straight from the 4155: (FHA Handbook)
