401K loan for the investor with a w2 job

So i was wanting to take a 401k loan out last week. I kick myself in butt for not following my gut and not doing it since i lost several thousands, like everyone else, the past several days. I'm wanting to purchase SFH with cash while i have a other closings ongoing for the next few weeks which ties up a lot of my cash. I'm concerned that if i do the loan now, in a few days the markets could creep up slightly giving me access to more 401k. I'm way to ignorant about 401k and stock markets to make an informed judgment on what i should do. Anyone have a similar scenario or advice?
