You have a couple of options which really depend on where you see the future. I see lots of indigestion in markets, high inflations, and the potential for lots of material shortages in the near terms.
If you think that inflation is going to continue, getting into the housing market while the rates are still low is probably a good idea even if you are overpaying. It's hard to beat a 3% loan and keeping your highest necessary cost fixed in an inflation environment. This is especially if you are going to be staying in the (NYC?) area for a while. Even if this is bad market timing it's hard to see this going to far sideways as long as you don't overbuy with respect to your income.
If you are pushing the house out for a few years, I think you want to diversify with a focus on defensive companies. Just some thoughts
Stocks related to food and raw material production. Archer Daniels is one of my largest holdings, they are the largest corn processor in the world.
Someone else mentioned I-Savings bonds which sound like a decent idea, although you are probably going to be hurt by the way they calculate inflation.
Since your are earmarking the money to buy real estate, you could put it in an REIT. These would likely retain housing purchasing power + pay out a dividend. I know $O is popular on twitter, but do your own research (I ended up buying an etf of REITs)
Tobacco stocks have high dividend yields which should offset any decreases in the market. The London based companies both have yields at about 9%.
Utilities are a decent defensive play which should pay cash and maintain purchasing power.
Microsoft and Google are still the best money printers in America.
The blue chip cryptocurrencies ($eth and $btc) are designed to be inflation resistant, but those markets have more indigestion than most.
