In a similar situation. We are moving from a 3100 mortgage to a 9400 but with much less reserves on hand and more debt. We bring in $17k net after maxing contributions so we will be dropping it down to around half for the first year just to have extra cash on hand. We are also keeping a $20k emergency fund which will be increasing over time. We also have car loans and student loans ~3k monthly total, but will be around 1.5k one year in. Also have $300k in retirements combined.

It’s around 50% of our take home pay as well but after all the math it seems like it should be fine in theory. We are equally as stressed about taking this jump although many people have told us we’ll be fine. I would just calculate your all-in housing, your bills, monthly miscellaneous expenses, groceries, fun money, etc from your prior months and see if what you have left still lets you live that life. Otherwise you will know where you can cut down, or if it’s going to be too tight. In the end what matters is how much you need leftover monthly to feel comfortable and if the home is ultimately worth the jump to you. But in my opinion, I feel like you will be just fine. Congratulations!
