Home Purchase Advice

Looking at selling our current home ($100k equity), and purchasing a $700k home.

My wife and I (both 31) gross ~$220k or so per year depending on her business income (relatively stable each year). She contributes 10% of her income to her 401k, myself 5% with 5% employer match, and I max out my ROTH yearly. We have $190k saved in a HYSA right now. Our only large monthly bill besides our $1,750 mortgage is $400/mo student loans. We have been able to save $4k monthly in savings right now for our home down payment (at least 20%).

Is a $3,900/mo mortgage reasonable for our situation? I’d like to not be house poor, but we are ready for an upgrade - moving outside of the city to a place more private with some land. We would have a year of expenses in a HYSA as an emergency fund after our down payment and sale of our current home. We’ve been waiting for quite awhile now for rates to drop, but it seems like they are fairly consistent at these levels.

Thoughts?
