I don't know where do you live but I don't think 1.2m$ is enough for retirement in anywhere. I would wait for at least 10 millions.
1M is enough to retire in Medellin, Colombia
1mil is enough in most of US, providing a few simple conditions:
1. Your children are independent and DONT leach off of you.
2. ~50% of your expenses are covered by Social Sec-very reasonable to expect $1250-1400/mo for each (H+W)=$30000-34000/year for husband and wife nuclear family (kids would probably leave the nest by then). Therefore, you would need to provide just 18K-22K/year from that 1mil to match average family income in US, which is 52K. It is not a life of super abundance, but with mortage gone, it may be better than most expect. $18-22k is quite possible considering that SAFE withdrawal is supposed to be 4% or 25K for 1mil in savings
3. your home is paid off
4. your RE taxes are small or subsidized-true for many states (for 65 and above).
As a sad comment to above, the average 401K (typical retirement account) in US is 14 thou and average 401K of those 55-64 is 104K, so almost nobody will have that million.
