This is the complete Bali property due diligence mistake guide. Twelve specific errors, each with a dollar cost and a prevention method. Total losses documented: $75,000. Every Australian investor should read this before signing any sale agreement.

Mistake 1 — Skipping the Title Search — Cost: $18,000 The villa had a disputed land certificate with two ownership claims registered at BPN. A $500 certified title search would have...

Mistake 2 — Using the Seller's Notaris — Cost: $12,500

The seller's recommended notaris did not disclose the villa's underground sewage system violated local health regulations. The notaris legally owed no duty to me — I was not their client.

Mistake 3 — Ignoring Local Zoning Regulations — Cost: $15,000

My villa was built 1.2 metres too close to the road frontage, violating setback regulations. A zoning certificate costs $100 and takes three days.

Mistake 4 — Not Checking Building Permits — Cost: $8,500

The villa's second storey was added without IMB building permits. An independent inspection before purchase costs $800.

Lease, Access and Environmental Risks — Mistakes 5 to 8

Mistake 5 — Overlooking Leasehold Expiry and Renewal — Cost: $6,000

I bought a leasehold villa with 28 years remaining on a 30-year lease. The lease had no renewal clause and the landowner had died.

Mistake 6 — Trusting Verbal Agreements — Cost: $4,000

The seller agreed verbally to include all furniture and appliances. When I took possession, the villa was empty. The sale agreement did not specify contents, so I had no legal recourse.

Mistake 7 — Skipping Environmental Site Checks — Cost: $3,500

The neighbouring property housed a commercial laundry discharging greywater into the shared drainage. The wet-season smell was unbearable, occupancy dropped to 35%. I paid $3,500 for a separate drainage system.

Mistake 8 — Not Verifying Access Rights — Cost: $4,000

The villa entrance crossed a narrow lane that the adjacent landowner claimed as private property.

Strata, Land Use and Timing — Mistakes 9 to 12

Mistake 9 — Ignoring Strata Title Risks — Cost: $3,000

I bought a villa in a small complex without reviewing the strata by-laws. The management committee had imposed a special levy for pool repairs that I was not told about.

Documentation and Legal Errors — Mistakes 1 to 4

Mistake 10 — Failing to Check Land Use Certificates — Cost: $5,500

The villa was built on land designated for agricultural use (sawah) under the local RTRW zoning plan. Legal and re-zoning costs: $5,500.

Mistake 11 — Skipping Flood and Drainage Assessment — Cost: $4,500

The villa had no history of flooding — until the first monsoon season. New upstream construction had redirected stormwater onto the property. Mitigation cost: $4,500.

Mistake 12 — Rushing the Settlement Timeline — Cost: $0 (Avoided)

I almost settled without completing any of these checks. The seller pressured me with a 'three other buyers' deadline. An experienced mentor told me to slow down.
