I just finished listening to the audiobook version of Nate Silver's book "The Signal and the Noise: Why So Many Predictions Fail - but Some Don't". In that book, he does talk about the math and accuracy of people's ability to make accurate predictions about the future. Definitely an interesting chapter in there about the real estate market in 2008 era which would be appropriate to read if you're interested in that. He also talks about trying to predict future which I found very interesting.
There is an interesting article from Harvard about predicting housing bubbles:

Economists are historically not great at predicting stuff like interest rates. Here's an image from a Wall Street Journal article that show what the economists predicted for interest rates and what actually happened:
This is where I got that chart from to give full credit and so you can read it from the source: https://obamawhitehouse.archives.gov/blog/2015/07/...
My belief is that if the smartest economists historically can't accurately predict interest rates, I suspect it will hard for them to predict crashes. Some will predict a crash and may ultimately be right and the some will predict a crash and may ultimately be wrong.
Personally, because my tendency is to be a worrier, I do think about possible market corrections and crashes. I wrote myself some software that allows me to model all sorts of what-if scenarios including market corrections and crashes.
For example, I just ran a quick comparison of buying $100K properties with just slightly positive cash flow ($25 per month at the time of purchase) one per year as a Nomad.
For the base scenario without a crash, I modeled appreciation to be the same as the historical Case-Shiller inflation rate of 3% per year.
For modeling the crash, I said what if we have 10% decline in property prices and rents per year for 3 years (starting in Jan 2021 and going through Dec 2023). After that, starting back up in Jan 2024, it resumes its 3% per year for both price and rent.
In both cases, I assumed you bought one house a year as Nomad (buy house as owner occupant, move in, live there for a year, then covert it to a rental and buy your next owner occupant). 3% down payment for the first 3 properties. 5% down payment for the remaining 8 properties.
So, in the "crash" scenario, you have 3 houses you already bought affected by the full crash. You buy 3 more houses as the crash is happening. The one you buy in Jan, 2021 goes down for 3 straight years 10% per year right after you buy it. The one you buy in Jan, 2022 goes down for 2 years and the one in Jan, 2023 goes down for a year. After that, you're buying the last 5 properties post-crash when the market is in recovery.
The big picture is the difference in terms of net worth is almost $2M OVER 40 YEARS with a market correction.
Almost $5,000 per month in True Cash Flow(TM) (which includes cash flow from depreciation and cap ex) in year 40.
And here's a breakdown of total equity between the two scenarios.
If you want me to change my assumptions and run the software again (or even change the setup) let me know.
