That sounds, fwiw, roughly in line with SF or NY 3br apartments. [1] By the way, that's actually part of the value proposition. New houses in the US are twice as big as they were in the 1970s - while costing the same per square foot on an inflation adjusted basis. This means 3br houses are 2x as expensive now as they were back then and is part of the reason folks are priced out of the market entirely. This is also a zoning issue.

We need small 3br houses and apartments. That doesn't mean we can't also have large 3br houses.
