Oversupply: The #1 Killer of Property Investment
Oversupply directly causes two major problems: falling rental yields and difficulty in reselling (subsale). Agents may tell you “this area will be booming,” but the data doesn’t lie.
Method 1: Check NAPIC “Unsold Property” Data (Ignore the Clickbait)
The most authoritative source to judge oversupply is not the agent, but NAPIC (National Property Information Centre). Focus on one core indicator: Overhang.
What is Overhang?
According to NAPIC, Overhang refers to units that have obtained CCC/VP (Certificate of Completion & Compliance / Vacant Possession) but remain unsold after 9 months. It reflects the level of inventory backlog in the area.
Reality Check (Hendry’s Logic):
News headlines may scream “Selangor has the most unsold properties in Malaysia!” Don’t panic. Look at segmentation:
Are the unsold units luxury homes above RM1 million, or RM300k apartments?
Is it in remote Semenyih or central PJ?
If you’re buying a RM500k mass-market apartment, and the unsold units are all luxury condos above RM1 million, this Overhang data has little impact on you. Focus on units in the same price range and type.
Method 2: 5km Radius “Future Supply” Estimation (Check Your Competition)
NAPIC looks at the past. This method looks at the future.
Open Google Maps and draw a 5km radius around your target project.
Count all incoming supply (under-construction projects). A typical condo project has ~800–1,000 units. If 5 projects are under construction, 4,000–5,000 units will enter the market in the next 3–4 years.
Ask yourself: Where will the people come from?
Jobs: Are there large offices (MNCs), tech parks, or financial centers nearby?
Transport: Is there an MRT/LRT connecting to the city center?
Amenities: Are there malls, international schools, or other lifestyle facilities?
Sifu’s Rule: If 3-year incoming supply is huge without supporting population growth (jobs, infrastructure), rental price wars after handover are almost inevitable.
Method 3: The Ground-Level “Reality Check” (Data Never Lies)
If you’re too lazy to crunch numbers, these three street-smart tests work:
Rental Yield Test: Search for 3–5-year-old completed condos in the area.
Warning: If rental yields are generally below 3–3.5% and dozens of units are available for rent, demand is weak, supply is high. New units will worsen this.

Auction Volume Check (Lelong): Search for auction listings in the area.
Warning: Large numbers of units being auctioned below their original price indicate previous investors couldn’t sustain payments—a red flag of oversupply + negative cash flow.

Occupancy “Light Test”: Drive by completed condos around 9 PM.
Standard: Is >70% of units lit?
If most lights are off (<30–40%), it’s mainly investment units—no one lives there. Avoid these properties.
Reverse Thinking: Can Oversupply Ever Be Bought?
It depends on maturity of the area:
Scenario A: Mature area oversupply (e.g., Mont Kiara, Bukit Jalil)
Though new units are many, amenities, schools, malls, and population inflow are strong. Demand grows with supply.
Strategy: Buy. Oversupply is temporary; prices may plateau for a few years but rise long-term.
Scenario B: Developing area oversupply (remote new townships)
Only “future vision,” surrounded by emptiness, but dozens of towers are built. Supply exists without organic population to absorb it.
Strategy: Avoid unless you plan to hold 10+ years, betting it becomes the next PJ.
PropertySifu Summary
Property investment is ultimately about supply vs demand.
Agents may paint rosy pictures, but lights at night and auction data tell the truth. In 2026, avoid areas with heavy homogeneous competition. Focus on areas with industry support and population inflow, where demand is real.
