I am just going to throw this out there and don't take this the wrong way please.
Your assets are 16x what my proposed numbers are when I plan to FIRE. This blows my mind.
I do live in a LCOL area and I have a child but holy crap batman how you or your wife could continue to work full time is mind boggling. I plan on me or my spouse working part time through the year for "fun money" this could go to anything we wanted but will more than likely end up being travel/vacation money.
I promise if you are paying 14k for property taxes/insurance that you could move to a LCOL area and buy a mansion with the money you have in your current property.
Our plan doesn't include any extravagant vacation homes or fancy cars but for $8k a year we will have the necessities covered and then some, add in one of us working part time for some ridiculous cushion there.
You have reached financial independence brother, you should have pulled the trigger a long time ago. Pursue your passions, spend more time with your kids, enjoy the fruits of your labor. DO IT.
