If you are about to purchase a home, do NOT change jobs until after the closing has happened. If you do your mortgage will very likely be denied.

If you have not closed yet, then yes. You have to show steady income. Your employment will and can be verified even up to the moment you are signing your closing documents or after if the monies have not been transferred and released yet.

You are safe with your mortgage as long as you are making your payments on time. People change jobs all the time, that is one of the reasons it is so difficult to get a mortgage today. But once you get the mortgage you are safe as long as you continue to make the regular payments. If you begin to struggle and fall behind on the payments you will then want to contact your lender immediately to see if they can work out some changes for you. Otherwise you are good.
Good luck with the new business!
As the others have stated, if you've already closed and are making payments then there's nothing the lender would do.
It sounds like you've set aside money and have some plans laid out. Going out on your own can have unexpected expenses and delay so make sure you have enough funds to cover everything until you are up and running.
Just be sure to keep your mortgage payments current, and good luck with your new business!
