3x national median income would actually mean something if real estate costs the same nationally, but obviously it doesn't. Many areas in the country costs far more than 3x in terms of real estate prices.
If you make the 3x the median income of the area you live in, then it would be a stronger argument.
Every time I propose this people think I’m on another planet but the lifestyle is really great tbh.
Probably the easiest way to find out before buying is to just stand in the lobby and ask the next person who walks past what they think.
My in-laws lived in a mid-height (4 floors) concrete-and-brick building that went up under Salazar. An equivalent building in the US would be built in wood and sheetrock pretty much everywhere. Even 5000 square foot doctors' palaces that go for half a million dollars are stick-and-cardboard. Solid construction you'd only find in highrises in urban centers, and even then it's not guaranteed that the walls aren't made out of cardboard.
You see these sprawling neighbourhoods of SFH's with 1.50 m separation between buildings and very much the whole lot paved over. Everywhere else there would be mid-rise multifamily buildings, but the American insists on an SFH, because soundproofing.
To find out what the quality of a building is you are best off just asking people who live there what they think. Apparently you can also request that strata give you information like owner complaints which may bring up noise disputes.
But what's the appeal of a high-rise? It requires too much space around it, it's not made for the human scale.
