Its really just building.

I grew up in a somewhat rural part of the US, basically just farm land and forests, but a few dozen miles from a city of ~100,000 people. The amount of NIMBYist "we gotta protect the farm" "we'd never sell to some big developer (spits on the ground)" you hear day to day was extreme, to say the least.

Ten years later, that city of 100,000 people is 115,000 people, a half-dozen miles closer to the rural farming community, and they just opened a strip mall outside of town. In another ten years they'll likely have a Starbucks and a luxury apartment complex. In thirty years that small community won't really exist; it'll be called an "exurb" of a city of 250,000 people.

My point in saying this in response to your comment is: Density brings money; and money trumps everything else. It trumps NIMBYism. It trumps Good Ole American Values. It can also trump inequality, weirdly enough; because density (aka money) increases the efficiency of our land use. The issue is: We aren't building enough.

> where will this end for a lot of investors

Constant-ish property asset values relative to baseline inflation. Its really not the end of the world. There's so many places to park money in the US economic system, its weird that we're so caught up in something so real and ugly as residential real estate. Go park your money in Nvidia.

Here's my take: the government should back low interest rate and high eligibility loans specifically for the purchase of housing which has never been lived in before. There should be some provision which allows the loans to be used in the case of initial development, or redevelopment if the new development has a higher density than the previous development on that lot (e.g. the lot had 1 unit before, now it has 4 units, you're good). These loans should be made available to individuals; two per person, some reasonable market-dependent limit per loan. That's it. If the specifics are correct, a program like this would fix an extreme number of problems the US housing system has. It would create a few problems, for sure, but critically: a program like this would create liquidity in the housing system, and its far, far easier to fix problems in a liquid system versus an illiquid one.
