Approved for home loan, but wife will probably quit or change job before loan execution (Jul 2027). Issues?

This is a sensitive thing to ask the bank so I thought I'd ask here.

We got approved for a home loan which is all in my name. My wife is the 連帯保証人.

She currently works but is considering quitting or changing jobs. The execution of the loan will be June 2026 for the land, and then June 2027 for the building. The homebuilder is already determined.

Is there any issue with my wife leaving her job or changing to a higher pay job sometime in between?

Thank you
