Higher mortgage to increase savings to invest?
Clearly this is doable and many people are doing exactly this.  At that kind of rate many will tell you to borrow as much as you can and invest.  This strategy does not work if you spend that money on dumb stuff, but you don't seem the type to do such a thing.  In some will argue that it is the only logical thing to do. Some will say that this is not a good idea due to risk.  Your chosen investment could lose value.  If this happens you would have been better off paying down your mortgage.   While my own interest rate is not as good as yours, it still pretty darn low (1.97%) after my tax discount.  Despite that I am aggressively paying down my mortgage.  My wife and I want to be debt free.  There is a certain freedom that comes along with that which cannot be explained by numbers.
