I might see how they may reject mine.
They must be pretty tight on lending criteria. Kind of anti-thesis to the whole credit industry at the moment, though morally that's supposed to be a good thing.
I wonder if they had a similar approach to my sister's bank who eventually approved her finance on a new house. My sister is paid on commission (but she has a "minimum retainer" that she is paid if she doesn't make a certain threshold, i.e. her pay is the retainer or commission, whichever is higher), which apparently was most unsettling for the bank she applied to. She had to get a signed letter of explanation from her employer before the bank was convinced that she possessed any financial capacity to service a loan.
I'd know there are a decent number of people here who are paid on contract terms rather than salary or other set wage.
