But that's the problem, someone else is buying those houses, and the market keeps going and will keep going.

As of now in March 2023, the market has slowed down and a bit less expensive, which was why the interest rates were raised. However, is not like houses sit on the market for long. As some other mentioned, there are a bunch of real estate managers buying houses/apartments and renting them, probably to that common man you mentioned.

They would need: to make credits easier for people who can't afford it, idk mark them as high-risk and give them a higher but variable interest rate, and then everyone can buy a house!!! /S (<- just in case people don't know, this is exactly the idea and what caused 2007 crash)
