My friend did the Mass Affordable Housing Alliance (MAHA) thing where you have to take a class. I saw that your wife would perhaps lower her income so take a look at the amount of annual aggregated income and also the amount of assets you both own, then check if that still works. I think the bank will require a lot of income information so I assume it will go off of W2.

If it does, sign up for a class ASAP, once you take the class, start looking at lenders (the class should be able to help with this I think), lawyers to help should also I think come from the class.
