I read the statement above about how people who are having babies and raising families need more space.
Yeah, probably more than a 1-bedroom apartment.
One of the issues today with the younger people is they expect a 3200 sf, 5br/3ba home for their 3-4 person family. They "need" a kitchen 3x the size of the normal kitchen in 1978 because they have an air fryer and $1800 coffee machine. Don't forget the pantry that is larger than the main bath of the house in 1978. They also need space for 2 dog crates for their two prized $3000 dogs they are so proud of.....when they are out and about..... not so much at home.
Younger people aren't willing to buy a fixer-upper or a smaller house. Yes, I know, smaller houses haven't been built in 35 years. Right now, I see a market for 1800 sf, 3br/2ba homes that can sell for $310k new. The problem is that the developer needed to secure the land to build 60 of these on for less than $8k/acre before infrastructure development and have little to no development fees or hoops to jump through. And when the HVAC for a new 1800 sf home is $20,000 today, plumbing system and fixtures are $17,000, electrical and lighting is $18,000.... those are major components of that $310k and not much left for fancy trims, countertops, 10' ceilings, lots of concrete, landscaping and home automation. Better be lucky you have a roof that don't leak and decent flooring for your feet.
There's a lot of complication and components to the situation we are in right now with housing, cost of housing, interest rates, etc. The only wholesale "fix" will be repeating 2008-2012.
