Mortgages aren't some small detail distorting the numbers. They make the difference between being able to afford a house or not. Having to live with your parents vs being able to buy a house and start a family of your own.

I was lucky to buy a house 10 years ago, and got a 3.5% fixed rate mortgage. Today the house value has gone up by 50%, and mortgage rates are about double at 7%. Just due to the mortgage increase alone, someone buying this house today would have a monthly payment about double what I am paying. I would not be able to afford it. On top of the mortgage rate increase, there's also that 50% inflation in the value of the house, meaning that if it sold today the new buyer (assuming they financed it) would be paying closer to triple (150% x 200%) what I am.
