How to read this: Sumba Villa Investment is an independent investment-intelligence guide — we research, compare and explain Sumba land and villa opportunities, then route serious enquiries to a vetted partner. We are not a broker, developer, financial adviser, notary or law firm, and this is general information, not investment, tax or legal advice. Foreigners cannot own freehold (Hak Milik) land in Indonesia, and nominee arrangements are risky and may be unlawful — never rely on them. Figures here are indicative ranges and can change; we never promise returns. Always do your own due diligence and verify everything with a licensed Indonesian notary (PPAT) and qualified counsel before you commit.
Price per are calculation in Sumba starts with one definition that sellers often skip: one are equals exactly 100 square metres. That single fact — what is an are land Indonesia uses as its base unit — is the arithmetic foundation everything else rests on. Get it wrong, or let a broker quote you whichever unit makes the number look smallest, and a parcel that costs IDR 2.2 billion can sound like anything from IDR 22 million to USD 13,000 depending on how the pitch is framed.
This page does the arithmetic openly, with dated listing-level figures, explicit conversion steps and a frank disclaimer: every price here is an asking price from active listings as of mid-2026, not a transaction record. No public Sumba transaction database exists. The gap between what a seller asks and what a buyer pays in a recorded deed is unknown, and anybody who tells you otherwise is either guessing or selling.
What Is an Are? The Unit Every Buyer Must Memorise
Indonesia measures land in are (abbreviated ca in older notary documents, from the Dutch centiare/are system). The hierarchy is fixed:
- 1 are
- = 100 square metres (m²)
- 1 hectare (ha)
- = 100 are = 10,000 m²
- 1 m²
- = 0.01 are
That middle line is the one to write on a Post-it note before you look at any listing. A parcel described as “99 are” is 9,900 m² — essentially one hectare. A parcel at “50 are” is half a hectare, or 5,000 m². These are not exotic conversions; they are the same ratio every time. The confusion enters when a broker quotes you per-are pricing for a large plot, per-m² pricing for a smaller one, or per-hectare pricing for a mega-parcel — and you have no quick way to cross-check.
Current Asking Prices: West Sumba Beachfront (as of mid-2026)
The verified range from active listings for beachfront and clifftop land in West Sumba — the coastal strip running south of Tambolaka airport, near the Nihi Sumba influence zone — is approximately IDR 22–24 million per are. One documented listing: a near-1-hectare oceanfront parcel approximately 15 minutes from Tambolaka airport at IDR 22 million per are, totalling roughly USD 130,000 at prevailing exchange rates.
Brokers also market comparable beachfront land "from approximately USD 95,000 per hectare" — which, at 100 are to the hectare, works out to USD 950 per are, or at roughly IDR 16,000 per USD, approximately IDR 15 million per are. The spread between IDR 15 million and IDR 24 million per are on comparable West Sumba coastal land tells you more about negotiating room and access quality than about any real price index, because there is no price index.
One figure to reject outright: some circulating sources quote "IDR 160–400 million per are" for Sumba land. That range is inconsistent with every live listing this desk has reviewed and is almost certainly a misprint or a confusion between per-are and per-hectare pricing. Do not use it as a reference point, and do not let a seller use it to anchor your expectations upward.
Converting Are to Square Metres: A Worked Example
Here is how to convert are to square meters land figures so that any quoting unit becomes comparable. Work through this with a specific West Sumba beachfront example.
The Starting Data
Parcel: 98 are of oceanfront land, West Sumba (near Tambolaka, 15-minute drive to airport).
Asking price: IDR 22 million per are.
Quote date: mid-2026.
Exchange rate used: IDR 16,000 per USD (illustrative — verify the spot rate on the day you calculate).
Step 1 — Convert Are to Square Metres
98 are × 100 m²/are = 9,800 m².
Step 2 — Total IDR Cost
98 are × IDR 22,000,000/are = IDR 2,156,000,000 (roughly IDR 2.16 billion).
Step 3 — Per-Square-Metre Price in IDR
IDR 2,156,000,000 ÷ 9,800 m² = IDR 220,000 per m².
Step 4 — USD Total
IDR 2,156,000,000 ÷ 16,000 = approximately USD 134,750. Call it USD 130,000–135,000, rounding for exchange-rate uncertainty.
Step 5 — Per-Hectare Equivalent
If the parcel were a full hectare (100 are), at IDR 22 million/are that is IDR 2.2 billion per hectare, or roughly USD 137,500/ha. Brokers who advertise "beachfront from USD 95,000/ha" are quoting a lower bracket of the same West Sumba market — not a different island or a different quality tier.
| Quote Unit | IDR Amount | Approximate USD | Equivalent in Other Units |
|---|---|---|---|
| Per are (100 m²) | IDR 22–24 million | USD 1,375–1,500 | IDR 220,000–240,000 per m² |
| Per m² | IDR 220,000–240,000 | USD 13.75–15.00 | IDR 22–24 million per are |
| Per hectare (100 are) | IDR 2.2–2.4 billion | USD 137,500–150,000 | IDR 22–24 million per are |
All figures are asking prices from listings, not recorded transactions. Exchange rate: IDR 16,000/USD (illustrative). Verify all figures locally before making any financial commitment. As-of date: mid-2026.
How Brokers Quote Selectively — and Why It Matters
The Sumba land price math example above is straightforward arithmetic. The problem is not the maths; it is which number gets quoted first.
A parcel at IDR 22 million per are sounds expensive to a buyer used to thinking in millions. The same parcel described as "USD 13.75 per square metre" sounds almost impossibly cheap to a buyer who knows that Bali hotspots in Uluwatu or Pererenan trade at USD 400–800+ per m² (IDR 60–120 million per are at mid-2026 rates). Neither figure is wrong. Both are the same land at the same price, expressed in units chosen to produce the desired reaction.
The per-hectare frame — "beachfront from USD 95,000 per hectare" — is the most common in international marketing because USD 95,000 reads as affordable while hiding that a 2-hectare parcel therefore costs USD 190,000 before a single foundation is poured. Run every quoted price through the three-step conversion above before reacting to it.
A related tactic: quoting a "starting from" price on land where the accessible, titled, road-connected portion is a fraction of the advertised area. The headline price is mathematically true; the effective price per buildable are is materially higher once you exclude the unbuildable coastal setback strip, the community access corridor, and the hectare of slope the title includes but no structure can legally occupy.

The Real Cost of Land: What the Per-Are Price Doesn’t Include
The asking price per are is the floor, not the ceiling. On raw West Sumba beachfront or clifftop land, buyers routinely discover that the effective cost of a ready-to-build site runs meaningfully higher once four cost categories are added.
Access Road
Many well-priced Sumba coastal parcels sit at the end of a graded track or no track at all. The main spine road from Waingapu through Waikabubak to Tambolaka is generally paved, but the last kilometre to a beachfront plot may not exist. A graded or paved private access road of 500–1,000 metres adds a budget line that does not appear in the per-are price. Get an engineer’s estimate, not a broker’s verbal assurance, before signing anything.
Title Clean-Up and Due Diligence
Indonesia’s rural land registry has systemic weaknesses — double certificates, disputed boundaries, girik (old letter-of-possession) land not yet converted to formal BPN title, and, specifically on Sumba, the risk of adat (customary) land sold without proper clan consent. A licensed PPAT and a BPN land-office verification are mandatory, not optional. Budget for independent title search, a licensed surveyor to physically peg boundaries, and confirmation that the parcel is not within a green-zone (LP2B sustainable agricultural land) or a coastal setback restriction under local RTRW zoning rules. These costs are small relative to the land price but their absence can make a cheap per-are price worthless.
Self-Provided Utilities
Grid electricity in West Sumba reaches towns and many villages, but remote coastal parcels frequently sit outside reliable grid coverage. Water supply on raw land is typically self-provided via borehole, storage tank and treatment system. Any serious development budget for a standalone villa includes hybrid solar-battery-generator electrical infrastructure and its own water supply chain. These are not unusual for frontier-market land investment in eastern Indonesia; they are the norm. Factor them in before comparing a "cheap" Sumba per-are price to a Bali parcel where infrastructure arrives with the title.
Leasehold Structure Costs
Nearly all Sumba land available to foreign investors is offered as Hak Sewa (leasehold), a contractual arrangement — not a registered land title. Extensions are contractual, not automatic, and depend on the original landlord’s cooperation and solvency over a 25–30-year initial term. Structuring a sound leasehold agreement, registering it properly, and building in extension mechanisms require a qualified notary and, for larger projects, PT PMA formation through BKPM/OSS. These legal and compliance costs are separate from the per-are asking price and should be budgeted explicitly.
Comparing Sumba to Bali: What the Price Gap Actually Measures
West Sumba beachfront at IDR 22–24 million per are (USD 13–15 per m²) sits approximately 3–5 times below Bali hotspot beachfront at IDR 60–120 million per are (USD 40–75 per m²). That gap is real. It reflects genuine differences in infrastructure maturity, tourism volume, liquidity, and verified rental demand — not a hidden value that the market has overlooked.
Bali hotspot land commands its premium because it sits at the end of an international airport with direct long-haul flights, inside a tested rental market with published occupancy and rate data, and on infrastructure (roads, grid power, piped water) that a developer does not have to self-fund. Sumba’s lower per-are price partly compensates the buyer for taking on risks and costs that in Bali are already resolved.
Promotional claims of "10–20× cheaper than Bali" are marketing estimates. The conservative, verifiable spread is 3–5×. The difference matters because the 3–5× frame leads to honest due diligence; the 10–20× frame leads to assumptions that a $10,000 plot will become a $100,000–$200,000 plot on someone else’s timeline and capital.
No public transaction database exists in Sumba. Appreciation claims — "prices up 1,200%," "rising faster than Bali" — are single-source broker claims with no independently verified baseline or timeframe. They are marketing. Treat them as such.
What This Page Cannot Tell You
This is general information about how to read and convert land prices. It is not investment advice, legal advice, or tax advice. No price cited here implies a future value. Asking prices shift; exchange rates shift; regulations governing foreign land access in Indonesia have changed before and will change again.
Before any deposit leaves your account: verify all figures with a licensed Indonesian notary and PPAT in East Nusa Tenggara; confirm title status and zoning directly at the BPN land office in the relevant regency; have the leasehold agreement reviewed by Indonesian property counsel. A PPAT’s core job is to verify ownership, encumbrances, boundary accuracy and that all taxes are paid before the deed is signed. That process is not a formality — on Sumba, where adat land claims and double-certificate risks are documented problems, it is the primary cost-control tool available to a careful buyer.

Frequently Asked Questions
What is an are in land measurement, and how does it differ from a square metre?
One are is exactly 100 square metres. It is the standard Indonesian land measurement unit used in property titles, notarial deeds and real-estate listings across the country, including Sumba. One hectare equals 100 are, or 10,000 square metres. When a listing quotes a price per are, multiply by 0.01 to get the per-square-metre equivalent, or multiply by 100 to get the per-hectare equivalent.
How do I convert a per-are price to a USD total for a West Sumba plot?
Multiply the plot size in are by the per-are IDR price to get the total IDR cost, then divide by the current IDR/USD exchange rate. For example, 98 are at IDR 22 million per are equals IDR 2,156,000,000 total. At IDR 16,000 per USD that is approximately USD 134,750. Always check the live exchange rate on the day you calculate — the IDR/USD rate is not fixed.
Is the IDR 160–400 million per are figure I saw for Sumba land accurate?
No. That range is inconsistent with all active listings this desk has reviewed for West Sumba coastal land as of mid-2026, where verified asking prices run approximately IDR 22–24 million per are for beachfront or clifftop parcels. The IDR 160–400 million per are figure appears in one source and is almost certainly a data error — possibly a confusion between per-are and per-hectare pricing, or a misprint. Do not use it as a benchmark, and do not allow a seller to use it to frame your expectations.
Why do brokers sometimes quote per-hectare instead of per-are pricing?
Quoting in whichever unit produces the most appealing number is a standard sales practice, not necessarily bad faith. Per-hectare pricing makes a large parcel sound cheaper in absolute IDR terms; per-square-metre pricing makes Sumba sound dramatically cheaper than Bali hotspots. Per-are pricing is the most common unit in Indonesian notarial documents and the one most useful for direct comparison. Convert every quote to per-are and per-square-metre before assessing it — the three-step conversion in this article takes under two minutes.
Are the asking prices cited here the prices I will actually pay?
Asking prices and transaction prices are different numbers. No public record of actual Sumba land transaction prices exists — the BPN registry records transfers, not sale amounts in a searchable database, and no independent price-index service covers Sumba as of mid-2026. Every figure on this page is an asking price from active listings, treated as indicative of the general market bracket, not as a guarantee of what you can buy land for. Negotiate, commission an independent valuation if scale warrants it, and verify directly with a local PPAT before committing funds.
