12 years until my son goes off to college

[Raul Cesar cortes]

I am a married and a father of a six year old boy who loves to swim. I have not reached full financial Independence but live very comfortable in Fresno CA. Currently have 3 fourplexes that cash flow over $1500 each and low mortgage on my dream house. i have an accepted offer on 4019 e calwa fresno ca. the property is 3 separate 2bd houses with garages on 1 APN. The seller has no existing leases in place says is charging $500 a month but will furnish leases at closing, market rent is at least $840 a unit. My dilemma is whether to hold or flip to purchase a pool for my family. I am trying to find balance with happiness for family and financial independence.
