Can I "income out" of a mortgage credit certificate?

[Account Closed]

Let's say that I want to get a mortgage credit certificate (MCC) on a home that I am going to live in.  It has certain income qualifications to get it.  At the time I purchase the home, I am within those parameters and get the MCC.  Afterwards, if I get married to a wealthy lady or if I get a big promotion and start making a lot more money, to the point where I no longer fit into those parameters after the home purchase, am I still able to claim the the MCC or do I lose it?
