Property transactions involve some of the largest sums of money most people ever handle, which is precisely why scammers find the sector so attractive. Fraudulent land certificates, phantom developers, and properties sold to multiple buyers at once are all real schemes that continue to claim victims. Knowing what to check and what questions to ask can protect you long before you put anything in writing.

Recognise the Most Common Warning Signs

Almost every property scam starts with something that feels too good to be true. A price well below the going rate in the area is the clearest signal. Compare listings on platforms like Rumah123 or Pinhome, and if the gap is enormous without any obvious reason, treat it as a red flag rather than a bargain.

Other warning signs worth watching for:

  • The seller creates urgency and pressures you to close quickly without time for verification.
  • A deposit or booking fee is requested before any documents have been shown.
  • Original documents are never available in person, only photos or photocopies.
  • The seller avoids face-to-face meetings and communicates only through messaging apps.

Indonesia’s financial regulator OJK also cautions buyers against paying a down payment before a home loan is formally approved by a bank, as this is a common opening exploited by fraudsters.

Verify Land Ownership Independently

Before anything else, confirm that the land actually belongs to the seller and is free of disputes. You do not need to visit a land office in person to do this.

The Ministry of ATR/BPN operates the portal bhumi.atrbpn.go.id and the Sentuh Tanahku app, both of which let you check a certificate number, land rights type, registered owner, and plot size online. Cross-reference whatever you find on the portal with the physical documents the seller presents.

Beyond ownership, also confirm:

  • Annual property tax (PBB) has been paid in full by the seller. Ask for the most recent SPPT tax notice.
  • There are no active land disputes. This can be confirmed at the local kelurahan office or land office.
  • The name on the certificate matches the seller’s identity document that you can verify in person.

Check the Developer’s Permits Thoroughly

When buying from a developer, never rely on brochures and showroom models alone. A reputable developer will readily produce their full permit documents without needing to be asked more than once. The core documents to request include a business licence, a Building Construction Permit (IMB) or the newer Building Approval (PBG), and a Certificate of Functional Compliance (SLF).

The SLF is issued by the government only after a building passes technical inspections covering structural integrity, architecture, and mechanical, electrical, and plumbing systems. Its presence is one of the most official confirmations that a building meets construction standards. If a developer cannot produce these documents, that is not a reason to wait longer; it is a reason to walk away.

Only Transact Through a Registered PPAT

One rule that must never be skipped: every property sale in Indonesia must be processed through a Pejabat Pembuat Akta Tanah (PPAT), a government-certified land deed official. A handwritten agreement, a regular receipt, or any unofficial document does not carry adequate legal weight and can leave you without enforceable rights over the property later.

You can check the list of registered PPATs authorised for the property’s location at atrbpn.go.id. Make sure the PPAT you use is registered for the correct area. A PPAT from a different city may not have jurisdiction to process the transaction.

Inspect the Building Carefully and More Than Once

A property in poor physical condition is not fraud in a criminal sense, but deliberately concealing major defects is deceptive and can cost you a significant sum after the transaction closes. For a second-hand home, visit at least two or three times at different hours: once in the morning, once in the evening, and ideally once after heavy rain.

A visit during or after rain is especially important in areas like Banjarmasin and its surroundings, where parts of the city sit on low-lying terrain with a real risk of flooding. Check whether the floor level is higher than the road outside, observe the drainage channels in front of and behind the house, and ask neighbours directly about flooding history in the area.

During your physical inspection, look for:

  • Cracks in walls or the foundation, particularly diagonal cracks that suggest structural settlement.
  • Stains or discolouration on the ceiling and in roof corners, which indicate water ingress.
  • A hollow sound when you knock on walls with your knuckle or a blunt object. That sound points to construction that is not solid.
  • The condition of the electrical installation and water pipes.
  • Door and window frames that are visibly skewed or stick when opened, which can indicate foundation movement.

For homes more than twenty years old or of significant value, hiring a professional building inspector is a smart investment. The inspection fee is almost always a fraction of what hidden structural repairs would cost after the deal is done.

Do Not Overlook What Is Under the Building

One factor buyers frequently miss is the quality of the soil under the foundation. The Ministry of PUPR emphasises that soil type is a major determinant of a building’s long-term durability. Clay-heavy and dark expansive soils absorb water and swell, then shrink as they dry out, creating stress that can cause structural cracking over years.

In South Kalimantan, parts of the land on the outskirts of Banjarmasin still have peat or swamp characteristics. Ask the seller or developer what type of soil is present and what foundation method was used. A professional developer can explain this clearly, including whether pile foundations or another technique suited to the local ground conditions was applied.

Where to Report Fraud or Misconduct

If you encounter signs of fraud or dishonest practice from either a developer or a private seller, there are official channels available depending on the type of violation:

  • OJK for issues related to financing or developer conduct that breaches financial regulations.
  • Ministry of PUPR for complaints about building permits or construction quality.
  • Police for criminal fraud, document forgery, or other criminal offences.

Keeping all communication records, documents, and receipts from the very beginning is one of the most effective forms of self-protection, well before any formal process begins.

Closing Thoughts

Caution is your strongest protection in any property transaction. Check documents independently, resist pressure to rush, inspect the property more than once, and make sure every formal step goes through a licensed PPAT. Follow these steps and your chances of becoming a fraud victim drop significantly.
