Should I continue to hold AAPL, GOOG, and MSFT? Cost basis in description

MSFT: 280

GOOG: 118

AAPL: 163

I’m in a sticky situation because although I do believe in the long term value of these companies, I may or may not need the cash in the summer of 2023 for a house down payment (50/50 chance I’ll need the money depending on how much my business generates). What would you do in this situation?
