So were we coast fire all along?

Wife and I are both 40, 18 years into our teaching career with pensions waiting at 53 combined around $100k. No cola, but we are in a state where we get social security, and it isnt reduced because we get a pension (im aware of wep). Our mortgage has been paid off the past 5 years, we live a simple life, spend about $60k yearly with 3 kids. We also have rental income $22k yearly and it is paid off as well. We also have $350k invested but that was a combination of a gift and us investing aggressively after paying off the house. We will probably upgrade to what is equal to $7-8k spending in today's dollars once we hit 53-55. I am thinking with our pensions and rental alone we have already hit coast fire. Anything im missing?
