Smart Borrowing Tips

Larger Down Payment
Every extra 5% down payment reduces total interest by roughly Rp 80-150M over the life of the loan.
Extra Repayments
An extra Rp 5M per month on a 20-year loan can save up to 4 years and Rp 400M+ in interest.
Rate Negotiation
Rates are negotiable in Indonesia. A 0.5% reduction saves Rp 200-400M over a 20-year term.
Refinance Early
Refinancing after 3-5 years when LTV improves can unlock rates 1-2% lower than initial terms.
