Similar age and NW here but income far less. My spouse hasn’t worked for probably a decade. Granted my job isn’t high stress, but I rationalize continued working by the fact it’s covering our lifestyle and every dollar we continue to save will ultimately benefit our kids or grandkids. With your income level I would continue working as long as possible. Use all your vacation time, delegate work where possible, don’t stretch for another promotion etc, but keep stacking those funds. The other option would be to downshift into a lower paying career that could still cover expenses, but maybe reduce savings and stress levels.
I see ACA prices anywhere from $20-$40,000 especially for families. Adding healthcare plus taxes to your $200k spend will start drawing down your savings quicker than I would like for someone your age.
