I have additional investments I can liquidate for a down payment up to $300k though that would trigger capital gains tax (some short term).

If the numbers work, pull the trigger!

Water bills coupled with property taxes and sale triggering reassessment pushed me out of Cleveland (and Milwaukee as well).

Would that trigger agent commissions by the PM the same way a straight sale of the property would?
