When stocks correct severely, 401k balances and IRA balances will go down significantly (in general overall) for the masses. When that happens, people won’t be as apt to buy a house even if they could. And when the crash happens, layoffs will also be happening and lending standards will tighten. All of that is likely to cause a housing correction too. So if you can, you might hold off.
The house I built is half the price of my lake house. So a correction on it won’t be nearly what it would be at a much higher priced house. Also, I’ve got a new build in the lower end of what’s commonly priced around where I live. So that will make it to where its easily affordable when things do come back and people want to buy. That way, it would make it easier for me to exit my house than many would, with higher priced houses or with older houses.
