The good news is that your credit score is good and puts you in the second-best tier for getting a good interest rate. The bad news is that most lenders like you to be employed for at least two years at the same place so they can feel confident of your status at work.
A new job is unknown territory for lenders. You might find a lender willing to approve your mortgage if you’ve been employed for only a year, particularly if you put down a larger down payment, you have a good credit score, and you have a strong work history.
Since you need to be employed a while longer to likely be approved for a loan, try to raise your credit score during that time. If you can get it to 760 or higher, you’ll be in the highest tier and should get the best interest rate available.
