Re: Mortgage tips and risks
The current vacancy rate in this area is 0.7%, in Switzerland it is around 1.1%.
And rates of construction are still low. Many places have no buildable land left.
A whole lot of people would have to move very quickly for there to be a sudden impact. A mass exodus is not likely anytime soon.
As to the OP, I think 'your friend' should stick to a budget where she can buy the place on her own. It's her stepping stone property. In 5 years she can look to upgrade.
