Switching Jobs during a Loan Approval/Closing

[Juan Carlos Castillo]

So I am trying to close on my first home, and have been getting a couple of offers of employment for the past couple of months that are significantly higher pay than what I am making right now. When I first started with my realtor I was making 52k, I told my mortgage broker that I was considering accepting an offer at another firm, and she told me to tell them to wait two weeks for the start date.

I managed to get the company to hold off for two weeks, but they served me an offer letter Thursday that expired Friday for 65k with a start date for the 13th of May. I signed and told my mortgage broker this morning and she had a fit. Her biggest concern is that I am moving from a construction project management position to an entry level engineer. I told her this is common for civil engineers, but can't seem to ease her mind.

Does she have a right to be concerned? Could I lose my deposit? After all I am still working in the construction industry and will be making more money.
