Rent vs. Buy a House in Indonesia: Renting and Investing Can Win

You found a house you like for Rp800,000,000. A similar house nearby rents for about Rp2,700,000 a month. Everyone around you says buying is "throwing money away on rent," so buying feels like the obvious move. But that gut feeling skips a step: what happens to the difference between what a mortgage actually costs you and what renting costs you, if you invest it instead? Once you run the real numbers, renting and investing the gap can leave you ahead of buying, and this article shows exactly when.
This is not a claim that renting always wins. It is a walk through the actual math, using Indonesia's real mortgage rates and real property price data as of September 2026, so you can run your own numbers instead of following a rule of thumb.
A KPR (Kredit Pemilikan Rumah, Indonesia's mortgage product) almost always starts with a low "fixed" promotional rate, then switches to a "floating" rate for the rest of the loan term (tenor). The floating rate is the one that determines most of what you actually pay, because it applies for most of a 15 or 20 year tenor.
As of September 2026, published floating KPR rates at major Indonesian banks range from about 11% to 13.5% a year: BCA at 11%, Bank Danamon at 12.5%, Bank Mandiri at 13% (on its KPR take-over program) and BNI averaging around 13.25%, according to rate comparisons at Wartafinansial and Kontan. A low first-year "fixed" rate you see advertised, sometimes as low as 2.99%, only lasts one to a few years before it converts to one of these floating rates.
One exception: FLPP, the government's subsidized mortgage program for lower-income buyers, locks a 5% rate for the entire tenor. But it only applies to homes priced roughly Rp166,000,000 to Rp240,000,000 depending on region, with a maximum buyer income of Rp8,000,000 a month, per government housing guidance summarized by Medcom. If your house falls in that price band and you qualify, the math in this article does not apply to you the same way, since a 5% fixed cost changes everything below.
For a regular, non-subsidized KPR like the Rp800,000,000 example above, this article uses 11%, BCA's published rate and the lowest of the four named above, so the comparison is not stacked against buying.
Buying that Rp800,000,000 house with a 20% down payment (DP) means putting up Rp160,000,000 upfront, then borrowing Rp640,000,000. At an 11% floating rate over a 15-year tenor, the monthly mortgage payment works out to about Rp7,270,000, most of which is interest in the early years.
Renting the equivalent house for Rp2,700,000 a month costs about Rp4,600,000 less every month. If you invest both the Rp160,000,000 you did not put down and that Rp4,600,000 monthly gap, instead of spending it, that money starts compounding: earning its own return, then earning a return on that return.
A reasonable, low-risk place to compare against is a reksadana pasar uang (money market mutual fund), the kind of low-volatility fund Indonesians commonly use for savings goals. These funds returned roughly 4.6% to 6% gross a year in 2025 and 2026, according to fund performance roundups from Bareksa and receh.in. This article uses 5% as a middle-of-the-range, conservative assumption. It is not a guaranteed return, and a stock-heavy portfolio could do better or worse in any given year.
The usual argument for buying assumes the house itself is quietly gaining value while you live in it. In Indonesia right now, that assumption is weaker than most people think. Bank Indonesia's own Residential Property Price Survey found its national House Price Index grew just 0.69% year-on-year in the second quarter of 2026, only slightly faster than the 0.62% recorded in the first quarter, according to CNN Indonesia and corroborated by Kompas and Fortune Indonesia.
That is a national average, and specific neighborhoods can do better or worse. But it means the "your house will just go up in value" assumption cannot be taken for granted the way it could in a faster-growing property cycle. If the house barely appreciates, most of what makes buying pay off has to come from something else, and there usually isn't a something else once the mortgage interest is accounted for.
Here is the full comparison over a 10-year holding period, using the Rp800,000,000 house, an 11% floating KPR rate, a 15-year tenor, a 4% gross rental yield (in the middle of Rumah123's reported 3% to 5% range for houses, per Rumah123's own explainer), a 5% return on invested savings, and the 0.69% actual property growth rate above.
| Buy | Rent + invest | |
|---|---|---|
| Upfront | Rp160,000,000 down payment | Rp160,000,000 invested |
| Monthly outflow | Rp7,270,000 mortgage payment | Rp2,700,000 rent |
| Monthly amount invested | Rp0 | Rp4,600,000 (the gap) |
| Asset value after 10 years | Rp856,900,000 home value | Rp976,100,000 investment portfolio |
| Minus remaining loan | Rp334,600,000 still owed | not applicable, no loan |
| Net position after 10 years | approximately Rp522,400,000 | approximately Rp976,100,000 |
In this example, renting and investing leaves you with roughly Rp453,700,000 more than buying does, after 10 years, before accounting for selling costs, property taxes or maintenance, all of which fall on the buyer only and would widen the gap further.
Three things move the answer, and you can check where you stand on each one:
Property prices grow faster. In this example, home prices would need to grow at roughly 5.1% a year, about seven times the actual 0.69% Bank Indonesia recorded, for buying to catch up with renting and investing over the same 10 years. Some specific areas do grow faster than the national average; check your own neighborhood's recent price trend before assuming it does.
Your mortgage rate is much lower. A 5% fixed-for-life rate, like FLPP offers within its price and income limits, completely changes this comparison, since the "cost of borrowing" almost matches the low-risk investment return instead of running more than double it.
You hold for longer than 10 years, and rents rise faster than the alternative you'd invest in. Rent is not fixed either. If rents in your area climb faster than a low-risk fund's return over many years, the gap this article treats as "the amount you invest" shrinks or disappears, and a fixed-payment mortgage starts looking more like a hedge against rising rent than a cost.
None of this means renting is always the better financial decision, or that buying is not. It means the honest answer depends on the mortgage rate you can actually get, the specific rental yield in your area, and how long you plan to stay, not on a rule of thumb.
This comparison only measures money. It does not weigh in on stability for a family, control over renovations, protection from a landlord who decides not to renew your lease, or the forced-savings discipline of a fixed mortgage payment for someone who would not otherwise invest the difference at all. Those are real considerations. They are just not financial ones, so they belong in your decision, not in this calculation.
If you do decide to rent and invest the difference, tracking whether you are actually keeping to that plan is where most people fall short, not the math itself. NetWort's Portfolio Health view shows your real holdings and how they're actually allocated, month by month, so "I'll invest the difference" turns into a number you can see, not a good intention that quietly stopped after three months.
