1. Is the mortgage in your name or both of your names?
2. Will you still be working with the same company when you move?
3. Does your husband have an offer letter that states what his new income will be?
All these are probably questions your lender should be asking as it will play a role in your qualification. Typcially a Verification of employment is completed that asks is employment likely to continue at the beginning of the process. If the answer to this is no. That could pose a problem. Also, within 48 hours of closing a verbal verification of employment is completed again. I think your current lender may be taken some precautions, but they need to give you the full picture so you can position yourself appropriately.
