Mortgage and new job

[Deleted User]

I'm looking for some advice with regards to purchasing a new house when I am looking to change jobs.

Situation is:

I have been in a new job around 8 months and me and my partner have recently bought a new build house due to be built later this year (October Completion). We are going through the initial buying now, and sorting mortgages etc as we speak.

However, I am having serious job issues and I am desperate to move. This isn't just a case of being bored, this is at the point of legal involvement around harassment and bullying!

I am not going to leave without a job to go to, (which will hopefully be imminent) and salary wise I expect an equal/increase, the job will be in the same field but more senior. (based on a role I am going to).

I'm wondering what happens with the mortgage and what I should do, my partner is in a stable secure job and has been for 5 years +, I am the primary earner and we have savings. However we don't want to lose this house, we have been looking for 18 months to find what we want at what we can afford, and have ten years of savings - so the risk is that if we drop out after we have put the deposit down we risk losing ten years worth of savings!

We are really stuck, we love the house and its what we want, however I am stuck as to what to do. I am going to speak to our IFA, I just didn't know if there was any advanced guidance I could have.

Thanks In advance!
