I am not tied to Munich, but my wife is so highly specialized that she always has to drive to Munich. There are no jobs for her outside of it. So the A94 is an option. She has been driving into Munich for at least an hour for many years and is accustomed to it. I also wonder how much longer she will put up with that.
I see no problem with setting up financing with the current salary, but what if we have children and my wife stays at home for several years or eventually only works part-time. Then 6500€ can quickly become 5000€ or less. And then I would rather not have to pay 2500€ for the house.
What I have not mentioned is that we have a very, very inexpensive apartment (120sqm) and pay only 650€ cold rent. The question is whether we should just stay there for the next few years. However, the risk exists that in 5-10 years houses will be much, much more expensive, since the A94 will finally be completed then (construction end Q4/2019).
If we exceed the pain threshold and look in small villages that are quite far from the A94, the prices are low but then it becomes impossible to commute.
