Payoff my new mortgage or use mortgage money to invest and pay down mortgage?

I just sold my house for $333K and purchased a new condo for $310K. My new mortgage is $248K at 6.875% requiring a mortgage of approximately $2400 per month. Do I pay it off? My payout from my sold house will end up being $285K after all closing costs. Probably a no-brained to just pay it off, but nice to have you chime in. No matter what, I have around $900 per month in property taxes and assessments on my new property and my old mortgage was only $650 per month. I have $1,200,000.00 saved in a 6o% stock / 35% bond/cash / 5% crypto portfolio. I’m 63 years old and earn about $35,000.00 per year. I want to put $25,000 into a kitchen remodel and my current profit will easily cover that. I will probably be making more like $20-25K in a couple years when I lighten up on working as I semi-retire. No other debt. Health is fine. Let me know what you think.
Thanks Terry!
