Since most people are on the side of the new normal and continuously low inventory forever and always going forward I'll play the bear case just so you know the other side of the coin.
From a bear perspective the risks in the market are in the US dollar losing value due to rising inflation and foreign investments turning away from our market. At the same time that this is beginning to happen we also have supply-side constraints that we haven't seen in a century and all it will take is the smallest of negative events to blow the powder keg off this bubble. People who are weary right now are seeing what is happening in the Chinese real estate market and feel like that will be what lights the fuse on the next recession (combined with the oil, gas and coal shortages affecting most of the world right now). Stock valuations are highly inflated right now, especially growth stocks/tech stocks which will tumble fast and hard when we enter an era of stagflation. Take Rivian as an example which is currently valued at 147 billion dollars, keep in mind this company has sold less than 200 vehicles which were all prototypes, that means a supposed tech car company that does not have a proven model (yes its backed by large mega-corps, but keep in mind GM almost bought Nikola recently before it was uncovered to be a complete scam), is somehow valued at more than 2x the likes of Ford Motor Company and GM. Tesla is also highly overvalued currently (even a year ago Elon Musk himself stated it was over-valued back when it was valued at only $400 a share), although it is at least a real company it will see its stocks likely halved or quartered when we enter a recession. This just one example you can find many many examples of over-valued companies on the market right now. This is because people are pouring their assets into the stock market to guard against inflation, that won't last forever though.
The competing argument says we can keep printing money forever, many times in history people have thought that this will work and it always ends in hyper-inflation and the devastation of the economy, if we continue down the money printing path at the rate we are going we will begin to see continuous double-digit inflation which will create significant civil unrest and rioting, point to the rioting in the 60s and 70s in America and Britain as an example of this, or the rioting in the Weimar Republic in the 30s, or the rioting in Venezuela the last few years. Its clear we are gearing up for a period of inflation because everyone is fleeing into asset classes and nobody wants to be stuck holding cash. If the Fed has any brain they will increase interest rates to combat rising home prices and drive investors out of the housing market, this will create a slowdown in the economy but it will guard against a much worse crash. They should have started raising interest rates at the beginning of this year but instead went for another year of quantitative easing so its already a bit late.
This economy could go either way to be honest. We could just see higher inflation rates, a steadily raising interest rate from the fed, and a bump in unemployment and the feds taking a larger market share of the working economy by paying more peoples rent, that is the best case scenario outlook for the next year or two. Or we could see 10-20% inflation year over year for the next 5 years, seller financing becoming the norm for home-buyers like it was in the 70s, oil and natural gas shortages (and coal shortages in China), which then results in empty store shelves and rising unemployment. The bigger threat on the horizon from that is less about whether your house was a bad investment (inflation will assuredly make it a good investment from a leverage perspective) and more about how miserable you and your tenants will be when you can't buy anything because supply is diminished and inflation is spiraling out of control. Not to mention the civil unrest causes another bout of mass rioting in the streets of major cities that your investment happens to be in and then that area never recovers.

Nobody can predict the future, but at some point the bear is right. Always protect yourself against the bear outlook on the market while moving forward to grow your wealth. Its not safe to hold on to cash right now that much is a given, the question is less whether to buy and more what and where to buy?
Texas imo is a fairly safe bet if you are going for real estate, but not without its risks. Holding a little bit of gold, crypto, etc is also not a bad idea, and if we do start seeing double-digit inflation its probably time to buy yourself a bug out bag and some dehydrated food just to be cautious. :)
