Earlier quoted context omitted.
Well, we have a lot in common then. Any basic mortgage calculator would show you that the mortgage is not viable, the interest would accrue faster than it can be paid back. The duration or the rate must go down. In the 80s, the interest rate was higher and the duration was lower. People didn't make a 30 or 40 years mortgage to buy a flat.
Its viable. But you cant pay as much which is why prices come down when rates go up...
Thus it is not viable.
It's a single equation with 3 variables. The monthly payment, the rate and the duration.
The payment is about 50% of the typical salary in the area. The rate is set by the economy. The duration is determined by the two other variables, it's not adjustable on its own.
