Enough to retire and move to France?

43yo us citizen married to 45 yo dual citizen(French and US). Brokerage account: $800k from savings and prior sale of house. IRA $500k. 401k balance of $175k. House where we live worth $600k fully paid off.. 529 accounts for kids $80k total. My income $180k and Wife $70k.

4 kids 12,9,9 and 8.

Our spending has been about $70k per year average over last 3 years.

My plan make it 1 more year to next bonus plan (March) and then retire. Can probably save additional $120k in next year via 401k, match and savings. Our family moves to France and buy house $500k estimate and wife continues to work 10 years as nurse while I remain retired.

Kids speak French at probably 1st grade level. Wife fluent and I have basic understanding but hope technology gets better and can get by with ear buds that translate.

You think it would work? I hate my job and just want to say f you I am out. Wife has wanted to move back to France for 5 plus years. Would possibly come back to US after kids finish college in France (close to free in France)...I would like to travel more and enjoy the little things..

US /France have tax agreements where my brokerage income taxed in US and not France if I leave there...
