People think I am full of it when I say that my household income (largish household with kids) is a quarter million a year and we are basically living like we are middle class. Money just doesn’t go as far as it used to.

As a millennial, I never would have imagined working my way up to this point only to find I can’t even buy a house. Oh sure, I could make the bare minimum down payment and get stuck with a super high mortgage payment, but if I lose my job or become disabled or unable to work, we would have no way to pay for it.

Groceries, housing, and insurance costs have more than doubled for us since 2019.

Same. My wife and I are in the process of trying to buy a house over an hour from town, because it’s the only way we’ll ever be able to afford one, and it’s still more than what our landlord paid for the house we’re renting. Housing prices have tripled in the last 8 years here. They doubled in the last two years alone. The house we’re renting would cost a million dollars to buy today and our landlord has a $1000 per month mortgage on it since she bought it right before the housing explosion. It’s pretty wacky that you can become a millionaire just by having been alive and financially stable a few years earlier, while everyone else is destined to be poor for the rest of their lives, even if they’re making a quarter million dollars per year.

Where in the world is this?

Also, is that a high-end neighborhood or a middle-class/lower class neighborhood?

It’s a normal-ass 1960’s neighborhood that your parents would have paid normal-ass prices for. The job market here exploded over the last 20 years, so there’s just too many people and not enough land. I’m one of those people, so it’s not like I don’t contribute to the problem.
There are neither too many people nor not enough land, but too many houses from the 60s passed down with initial property tax values and too many NIMBYs preventing new construction of large apartment buildings.
There are tons of big skyrise apartment complexes and dozens more in the works. But they all get labeled “luxury apartments”, despite basically being tiny little rectangles with no windows except for a sliding glass door at the end, and they cost just as much as a house to rent. The more traditional apartments have mostly been converted to condos and they’re also very expensive. It’s just crazy expensive here, despite your choices! Lots of people commute for over an hour each way and then it’s still a half million dollars for a decent house. You have to live at least an hour and a half in the right direction to get something for less.

People live in worse apartments they can afford, so they buy a luxury apartment. Their apartment is now open to a person who could afford that apartment, but not the luxury apartment, so theirs gets filled. This repeats down the chain of quality/desirability/cost.

Every new apartment adds supply, thus adding negative price pressure.
