Hi all Sifu, I got one question about the house/mortgage loan.

I bought a new property last year (new project) and without DIBS.

Since my bank already start charge us interest based on construction progress so what is the benefit if we pay more than the interest amount into our loan account before the project complete?

If I do so is it will deduct my loan's principle or principle + interest?

Or should I wait until the actual loan repayment period start then only I put more money into the loan account?

Thank you all Sifu in adavanced
