Agree, so we decided to sell the existing house and change to a bigger one as the interest rate is really attractive. 2.5% which is even lower than the staff rate of banking.
Yes, the mortgage rate is at the bottom now, it will go up again very soon. Banks have started to raise it and reduce the assessment value of property, and also tighten up the lending ratio to income. So need to consider one's affordability in long term in view of the coming rising mortage rates.
