Comparing a 7.99% one-year fixed mortgage quote in Jakarta

Refinancing after twelve months cannot be essential to making the numbers work. With that constraint, I am assessing a Jakarta mortgage quote at 7.99% fixed for one year on a purchase of roughly IDR 15,480,000,000.

The rate shown at first did not include the full effect of lender fees or the applicable loan-to-value band. For a fair comparison, should I calculate all cash paid in year one together with the balance left at the reset date, rather than rely mainly on APR?

I also want to verify the early-repayment conditions, portability and the rate-setting process after the fixed period. Which lender document should contain those details, and should arrangement fees be included even if they are added to the loan rather than paid upfront?

For a one-year fix, I would compare total cash paid during those 12 months plus the loan balance remaining at month 12. Include every lender fee you must pay to obtain that specific rate. APR can help, but it may obscure the issue if it assumes a longer period while the rate changes after one year.

Is IDR 15,480,000,000 the purchase price or the proposed loan amount? The loan-to-value tier cannot really be compared without the down payment and actual principal. The repayment structure and total term are also missing, and both will materially affect the monthly payment and outstanding balance after the fixed period.

IvanWhite has identified the key gap. I would ask each lender to quote the same loan amount, term and repayment structure rather than comparing their headline examples. Then put the first-year interest, principal repaid, arrangement fees and any compulsory upfront charges into separate columns. That prevents a lower rate from hiding a more expensive first year.

One caution: do not automatically allocate the whole arrangement fee to year one if you genuinely expect to keep the loan for many years. I would run at least two holding periods—12 months and a longer period—and show the fee both as an upfront cash requirement and spread across each period. Otherwise the comparison can favour either refinancing or staying put simply because of the chosen timeframe.

I disagree slightly on using a longer period unless the post-fixed rate is clearly stated. Once assumptions about future rates enter the sheet, the result can look precise without being reliable. The clean comparison is the contractual first year, followed by separate reset scenarios. Also price the early-repayment terms into any refinance scenario; refinancing is not a free exit.

Monthly affordability deserves its own stress test. Work out the payment during the 7.99% year, then repeat it using several higher reset rates while keeping the same remaining term and balance. If the payment only works when refinancing is available, that answers the risk question regardless of which lender has the cheapest first-year total.

I would request a one-page schedule from every lender showing: cash due at signing, monthly payments for year one, balance after month 12, the reset mechanism, and costs for full or partial early repayment. For portability, ask exactly what happens if the Jakarta property is sold and another is bought—whether approval, valuation, loan-to-value or fresh fees can change. A feature labelled portable is not necessarily a guaranteed transfer on unchanged terms.
