What would you do if you came into 250k

I own a 3 family I bought for 140k 5 years ago the market exploded where I am and it is now worth 700k maybe more. A 3 family close just sold for 860k but has a driveway and is in slightly better condition. It is cash flowing about 2k a month after expenses. I am considering selling it but I have no idea what I would do with all the extra money. Context I am 31 years old with no kids but married. I live in a separate 3 family from the one I am considering selling.
