Obviously I can only speak for myself. But my partner and I have a combined income (in a LCOL area) of about $120k, plus OT that he works & my annual bonus.

I am the only person on our new mortgage, because we are not married. Our house is $167k and we put 5% down with a 6.3% interest rate. And while I know I could absolutely afford it without him, I am grateful that he will also be paying into the mortgage because it takes a lot of pressure off our budgets and allows me to continue saving, as well as pay down more of the principle to remove PMI sooner.

The most I would have wanted us to spend was $200k, which still felt like a stretch while house hunting. We got lucky with a small, starter home that we loved. And housing prices are obviously lower here than big cities. With our HHI at 75% of yours, I cannot imagine us buying a house for $400k+, even with both of us on the mortgage. It would truly leave us house poor. If $560k is the most reasonable price you can find in your area, I understand. But if there are ways you can downsize a bit, I would recommend it to avoid feel too strapped in your budget.
