They forgot the last property crash and global financial crisis.

For example I know someone who has an Airbnb right now in Turks and Caicos and the lender called the loan on them because of the financial crisis as lender is looking for liquidity.

E.g. the 2009 housing crisis.

They call it "stabilization" but in much of the outer boroughs the free market rents aren't far off from stabilized rents.In addition, if you look at the 2008 financial crisis, multifamily properties in NYC fell 16% (using cap rate data) I believe.

I have heard many people say that inflation in our housing market will lead to higher interest rates which will ultimately lead to an affordability crisis and a significant drop in housing prices.

If you chose 10 units because the cashflow was better at the time of purchase you need to do serious math to determine whether or not the 20 units with the lower cashflow would have beat out your 10 units big time in 1, 2, 5 or more years.As for going from Rockstar to bad times, I personally never met a multi-unit investor who lost money back in the 2008 crisis nor any other downturn.

Rent control seems to work for a few renters to keep them in but eventually ends up in less housing stock and leads to housing crisis and underbuilding.

Regardless of the recent crisis, real estate is still a good, long-term investment.

I couldn't get anyone to give me a quote on materials because of the "supply chain crisis".

I remember the SnL crisis in the early 90's (commercial mortgage crash).
