What do you mean by small and I think context of where you live matters.
Around me there are an abundance of 0.75k-1.5k sqft homes, typically they are older (1940-1980), and they are between $180-250k. They aren’t in high demand because they are older, they may need some TLC, they have old styles, they are 45 min - 1 hour drive from the big city, and they may not be as big as people want.
I have coworkers who lament not being able to buy a house, but when you talk to them they are looking at 2500+ sqft, less than 10 years old, 20 min from downtown, but $425k.
EDIT: After typing this I opened Zillow and within 30 seconds found a house across town that’s 980 sqft, $115k, 1950’s, but you’re gonna have a 45 minute (minimum) commute every day unless you leave for work at 5 am.
EDIT 2: Oh and 0.34 acres with no HOA
Maybe but it could crash anyways. JP Morgan tried to stabilize the stock market in 1929 by buying up stocks, but it collapsed anyways and led to the Great Depression.
