Brooklyn Family not sure where to go next

[5yearstillFIRE]

We moved to Brooklyn right after 9/11 had kids and bought a two family townhouse during the brooklyn real estate low after the recession. We currently make 1K more than our mortgage on the other unit while we live in the same building. My wife has a corporate job and I am freelance. We were also early investors in a brewery in brooklyn and are looking to receive 350K at signing and 1.2M over 5 years to almost buy us out (from 11% to 2% ownership). I don't want to pay all of this back in taxes. I want to tax defer all of this and and do the IRA conversion ladder. Wife hates her corporate life. We have other real estate properties in upstate new york that break even or make 10K a year. Do you pay off your 350K mortgage on the town house that makes you money? Its only a 4% interest rate. Currently we are paying an extra 500 a month toward the principle on top of the bi monthly mortgage payments? I would love to meet with other people in the FIRE community in NYC but it seems we are few and far apart. I have searched for hours for and accountant in NY the even references or mentions FIRE and so far none to be found. Any help would be great. We are a pretty frugal family have a 65% savings rate with two kids in public school in brooklyn.

I'd pay off (or refinance) a 4% mortgage since that's fairly close to a decent rate of return and is basically zero risk return.

Otherwise... yeah, sorry.  I live in rural Idaho.  Those are numbers that have no relevance in my life, and I can't help with city life.
