The usual idea of course, is making some interest or earnings on the cash and if the situation is on hold on what to do… buying a house or property…or just up in the air for an unknown time keeping the cash liquid, I might toss it in the bank until can figure it out. Yeah, sucks on interest; but da cash is there, all of it, when you want it quickly. Buying a house to rent or flip could cause some money issues if the place needs fixing up or other problems undetected…and if relocating, another possible ball & chain. As suggested, if it were me, I’d consult with an expert assuming the sum is large, as there may be other options to keep the cash liquid, avoid taxes, make a decent earning, etc. Appears your daughter has a lot to think about with her future and may need some or all of the money. If she’s not set with a retirement fund another thing to ponder on with some of the money.
