Home Loan: Borrow More vs Less & 30yrs vs 10yrs

Hi all,

What's the difference between borrowing 80% vs less and also 30yrs vs 10yrs ?
Other than repayment amount being different, does it affect the amount of interest incurred as a whole?

Say an apartment $500k
You have $250k cash

Do you borrow $250k over 10yrs
or,
borrow 80% ($400k) over 30yrs, but then you still put your whole $250k cash in offset acct.

Is there any difference other than the difference in repayment amount ?
I would've thought the total amount of interest paid in the end is going to be the same ?

Thanks.

  • Go for borrowing less and the offset account option especially if it is going to be your ppr

    30yr loan and borrow your max is more used for investments so you can offset your tax etc and hope for equity.

  • Depends what you end up doing with the $250K long term??

  • I would also like to know this. I just a loan approved for 680K. I could actually go with 500K as I have some spare cash but decided to go with full loan as I need some cash as a contingency measure. I did some calc and couldnt find much difference.

      I would go with the full loan. Why? as you have mentioned, contingency measure. Life circumstances change, jobs are not stable like they used to be and you might not get the opportunity to borrow this amount again. (It depends on your finances etc)
      Utimately it is important on how you can control your spending of course.

      I believe that you can 100% offset the max borrowed amount and the higher repayments will take affect when you withdrawl the money.

      E.g. 680K - 100K savings = 580K in repayments p/m
      Take out further 50K then 620K in repayments p/m

    "borrow 80% ($400k) over 30yrs, but then you still put your whole $250k cash in offset acct."

    This, not only are you reducing your repayments, you also give yourself access to your money when you need it, as long as its a 100% offset, and none of those partial offset scam loans.

    There is a little known mathematical fact, but in first 6 years of a 30 year loan, you pay 30% of the total interest payable of the loan, so within 20% of the loan length, you pay 30% of the total interest. That means the offset is more effective from day 1, than day 2190.

    btw, you can use this calculator as a proof of concept, as for the %'s go. also enter in your data for comparisons sake.

    Scenario 1.

    Sink all savings into apartment and borrow 250k for 10 years.

    Assumptions :

    Interest = 5%
    Term of loan = 10 years
    Repayment frequency = Monthly.
    Offset amount = $0

    Monthly repayment = $2,651.64 / month
    Lifetime interest paid = $68,196.55 over 10 years

    Scenario 2 - Borrow 80% ($400k) over 30yrs, but then you still put your whole $250k cash in offset acct. Where the f&%k did the other $100k come from but nevermind.

    Assumptions :

    Interest = 5%
    Term of loan = 30 years
    Repayment frequency = Monthly.
    Offset amount = $250k for the life of the loan from Day 1.

    Monthly repayment = $2,159 / month
    Lifetime interest paid = $27,839 over 17 years (Why is it 17 years and not the 30 years you stipulated? Because you have a high repayment amount for essentially a small principal amount of $150k so you pay it fast and the term of the loan is cut by 13 years).

    Please note that scenario 2 includes this mystical $100k from nowhere.

    • My bad. Should be $150k left for offset.

        New loan term is 19 years with total interest payable of $93,150.
