IDK, the student loans program in the US didn't work out very well, and a lot of people just ended up with a ton of debt they couldn't handle. I'm worried the same would happen with a federal housing loan.

What we need instead is better housing density. Right now, if you want to buy a property (at least in the US), you need to also buy a car and commute long distances because that's the only way you're going to be able to afford a place at all. If we instead built more mixed housing near transit lines (e.g. business at ground level and a purchasable apartment above it), you could own something and not need a car to get around. That would work for the first few years, and if you decide to grow your family, you could use your equity as a down payment on a larger place.

But we really don't have much in the way of a starter home. In my area, $300k is "cheap," and with loans now around 7%, you're going to need a larger down payment to keep mortgage payments reasonable. Most new construction around here is either luxury apartments or high end housing.
