Between 2019 and 2024, the price premium that Penang island held over the mainland shrank from 68% to 55%. The average mainland home transaction rose 21.5% over that period, from RM359,933 to RM437,223, while the average island transaction rose only 12.5%, from RM603,677 to RM679,175. The gap did not close because the island got cheaper. It closed because the mainland got more expensive, faster.
That single figure reframes the question most Penang buyers still start with. For thirty years the first decision was “island or mainland”. The transaction record now suggests the more useful questions are which sub-market, which product type, and which of the two sides is carrying the heavier unsold burden. This article works through the district-level numbers, the supply pipeline, and where the data is thinner than the headline suggests.
How much has the island–mainland gap actually narrowed?
The five-year comparison below is drawn from EdgeProp’s EPIQ transaction database, which compiles recorded residential transactions across the state. The premium column is the percentage by which the average island transaction exceeded the average mainland one.
| Measure | 2019 | 2024 | Change |
|---|---|---|---|
| Average island transaction | RM603,677 | RM679,175 | +12.5% |
| Average mainland transaction | RM359,933 | RM437,223 | +21.5% |
| Island premium over mainland | 68% | 55% | −13 points |
Statewide, the average residential transaction price reached RM508,837 in 2024, roughly 19% above the 2020 trough, with total recorded transaction value of RM7.13 billion for the year. Volume has also grown: Penang recorded 48,496 residential transactions across 2023 to 2025, up 7.8% from 44,986 across 2020 to 2022.
Which mainland districts drove the convergence?
Three mainland sub-markets did most of the work. Each has an area page on this site, and each moved for a different reason.
| District | Avg transaction 2019 | Avg transaction 2024 | 5-year change | What changed |
|---|---|---|---|---|
| Batu Kawan | RM392,070 | RM593,410 | +51.4% | Product mix shifted from terraces to cluster homes, semi-dees and mid-range high-rise |
| Alma, Bukit Mertajam | RM445,776 | RM622,228 | +39.6% | Commuter maths: freehold landed, schools nearby, roughly 35 minutes to the island by bridge |
| Nibong Tebal | RM306,043 | RM448,023 | +46.4% | Cheap land plus the commuter belt extending south |
Batu Kawan is the clearest illustration of why an average price can be misleading on its own. Its transaction volume actually fell over the period, from 189 recorded sales in 2019 to 137 in 2024. The average rose because the products on offer changed, not because a like-for-like terrace house appreciated by half. A buyer comparing a 2019 headline average with a 2024 one is often comparing two different housing types.
Why the mainland kept pulling ahead
The mainland accounts for roughly 71% of Penang’s land mass, houses more than half of the state’s workforce, and contributes close to half of its manufacturing value, according to Think City managing director Datuk Hamdan Abdul Majeed, whose organisation runs urban regeneration programmes on both sides of the channel. Employment, not marketing, is the engine here.
The most recent example landed this week. German life sciences manufacturer Eppendorf SE has taken a 60-year lease on an 11.82-acre plot at Bandar Cassia Technology Park in Batu Kawan from Penang Development Corporation, for its first Southeast Asian production facility. The company plans to spend about €40 million, roughly RM186 million, on a greenfield plant of about 172,200 sq ft. Construction is slated to begin in the fourth quarter of 2026, production is expected to start gradually from 2028, and Eppendorf projects around 130 employees by the end of 2029. PDC notes the plot has been laid out to allow a later second phase.
One plant with 130 jobs does not move a district average by itself. The pattern does. PDC records Penang exports of professional, scientific and controlling instruments of RM187 billion between 2021 and 2025, averaging about 72% of Malaysia’s total in that category. That kind of concentration produces a steady stream of salaried households looking for homes within reach of Batu Kawan, Simpang Ampat and Perai. We covered a related shift in ownership at the Batu Kawan medical hub in our note on what FBG’s proposed exit tells new launch buyers.
Infrastructure did the rest. The 24km Sultan Abdul Halim Muadzam Shah Bridge, opened in March 2014, made the southern mainland commutable. Planned rail, including the 29.5km elevated Penang LRT Mutiara Line, is expected to compress that commute further. Our earlier piece on the RSNPP 2040 structure plan sets out which corridors the state has formally earmarked.
Why the island still commands a premium
Scarcity has not gone away. Developable land on the island remains limited, development costs are higher, and demand from senior manufacturing staff, expatriates and lifestyle buyers has held average island transaction values firmly above RM450,000 throughout the period.
George Town is the standout. Average residential transaction prices in the George Town planning region were essentially flat between 2019 and 2022, at RM637,986 and RM637,834 respectively, both well below the 2018 peak of RM919,880. Then 2024 broke the pattern: RM897,085 average across 496 recorded sales, a 40.7% jump in average price and a 42.1% jump in volume against 2022. Total transaction value in the planning region nearly doubled in two years, from RM222.6 million to RM444.9 million.
Three factors line up with that timing. Tourism recovered, with cruise arrivals at Swettenham Pier returning to roughly pre-pandemic volumes by mid-2024 and heritage-core hotel occupancy exceeding pre-pandemic levels for several months of that year. Senior staff from the manufacturing belt showed a preference for living near the heritage core and its amenities, with average Tanjung Tokong condominium prices moving from RM944,047 in 2022 to RM1,136,330 in 2024 alongside a 19% volume increase. And several large projects launched in the 2018 to 2020 cycle hit completion or final-phase release in 2024, concentrating recorded sales into that year.
The supply picture: where the unsold units actually sit
This is the part that rarely makes it into a launch brochure, and it is the part that should shape a shortlist. EdgeProp’s database, built on Housing and Local Government Ministry records, counts 161 active residential projects in Penang representing 44,366 units in the pipeline. Of those, 16,561 units, or 37%, are unsold.
| Pipeline measure | Island | Mainland | State total |
|---|---|---|---|
| Active residential projects | 76 | 85 | 161 |
| Units in active projects | 17,258 | 27,108 | 44,366 |
| Unsold units in active projects | not split by side in the published data | 16,561 (37%) | |
The mainland now carries more forward supply than the island, by both project count and unit count. If take-up holds, the mainland will absorb more units over the next four years than the island does, which is a genuine reversal of the historical pattern. If take-up does not hold, the mainland also carries more of the risk.
One segment stands out. Across 14 serviced apartment projects totalling 6,414 units, 3,585 units, or 56%, remain unsold. Several flagship high-rise launches are absorbing units at rates well below the 2% per month figure the Malaysian market generally treats as healthy. Urban Prestige Properties team director Eugene Tan observes that serviced apartment demand has moderated, partly because of higher assessment rates, and that although more than ten projects have launched since 2025, only a handful have achieved significant sales.
A separate official measure points the same way. NAPIC’s Property Market Status Report recorded 3,165 completed unsold residential units in Penang in the first quarter of 2026, up 16% from 2,729 units a year earlier, ranking the state fifth nationally. Condominiums and apartments made up 2,215 of those units, about 70%, with the largest single band being the RM200,001 to RM300,000 price range at 708 units.
Note that these two datasets measure different things. The 16,561 figure counts unsold units inside active projects, including those still under construction. The 3,165 figure counts only units that are physically completed and still unsold. Both can be true at once, and neither is a statement about any individual development.
What this means when you shortlist a new launch
Henry Butcher Malaysia director Jason Teoh characterises the state as moving from a volume-driven cycle to a selective, fundamentals-driven one, and warns that it is splitting into two tiers: well-positioned developments holding up, undifferentiated ones facing heavier competition. PE Land Group chief executive Joanna Ling makes a related point, that oversupply talk should be read by price segment and location rather than applied to Penang as a whole.
Practically, that suggests five checks before you commit:
- Compare like with like. A district average that jumped 50% may reflect a change in product type, as Batu Kawan’s did, rather than appreciation on a comparable home.
- Check the segment, not just the address. Serviced apartments carry a 56% unsold rate across the state’s active projects; landed and low-density stock in employment catchments has behaved differently.
- Ask about absorption. Roughly 2% of units per month is the general benchmark. A project well below it in a district with heavy forward supply deserves a harder look.
- Map the commute honestly. Alma’s rise is commuter maths. If your workplace is in Bayan Lepas or Gelugor, time the bridge crossing at your actual departure hour before you decide the mainland works.
- Separate announcement from delivery. The Penang South Reclamation scheme and the Mutiara Line are long-horizon items. Reclaimed land and rail stations change a location’s profile when they are built, not when they are announced.
Where to look on each side
If the mainland is where the maths lands for you, the active area pages worth browsing are Batu Kawan, Bukit Mertajam, Butterworth, Simpang Ampat, Perai and Nibong Tebal. On the island, the concentrations are in George Town, Gelugor, Bayan Lepas, Tanjung Bungah and Air Itam. Each page lists the current projects we track in that district, with unit types, sizes and completion targets.
Where this data is strong, and where it is thin
The transaction averages, district breakdowns and pipeline counts here come from a single compiler, EdgeProp’s EPIQ database, drawing on ministry and transaction records. That is a serious dataset, but it is one organisation’s compilation rather than a direct government release, and averages of recorded transactions are sensitive to which products happened to sell in a given year. The NAPIC completed-unsold figure is an independent official measure and points in the same direction on oversupply, which is why we have included it, but it counts a different population of units.
Two things the published material does not tell us: the unsold 16,561 units are not split between island and mainland in what has been released, and the district averages are not adjusted for changes in unit size or type. Where a number here is doing a lot of work, we have said which side of that line it falls on. Treat the direction of travel as well supported and any single-year figure as indicative.
Frequently asked questions
How much more expensive is Penang island property than the mainland?
In 2024 the average island residential transaction was RM679,175, against RM437,223 on the mainland, a premium of 55%. In 2019 the same comparison was RM603,677 against RM359,933, a premium of 68%. The gap has narrowed by 13 percentage points over five years.
Which Penang district has seen the largest price increase since 2019?
Among the mainland sub-markets, Batu Kawan recorded the largest increase in average transaction price, rising 51.4% from RM392,070 in 2019 to RM593,410 in 2024. Nibong Tebal rose 46.4% and Alma in Bukit Mertajam rose 39.6% over the same period. Part of Batu Kawan’s increase reflects a shift toward larger and higher-specification products rather than appreciation on identical homes.
Is there an oversupply of residential property in Penang?
It depends on the segment. Across 161 active residential projects covering 44,366 units, 16,561 units, or 37%, are unsold. The concentration is heaviest in serviced apartments, where 3,585 of 6,414 units across 14 projects are unsold, a 56% rate. Separately, NAPIC recorded 3,165 completed unsold residential units in Penang in the first quarter of 2026, fifth highest among the states.
Does the mainland or the island have more new supply coming?
The mainland. It has 85 active residential projects with 27,108 units, against 76 projects and 17,258 units on the island. If take-up rates hold, the mainland will absorb more units over the next four years than the island will, reversing the historical pattern.
Why did George Town prices jump in 2024?
Average transaction prices in the George Town planning region rose to RM897,085 in 2024 across 496 sales, up 40.7% from 2022. Three factors coincided: international tourism recovering to roughly pre-pandemic volumes by mid-2024, senior manufacturing staff showing a preference for living near the heritage core, and several large 2018 to 2020 cycle projects reaching completion or final-phase release that year.
Will the island–mainland price gap keep closing?
The published data does not settle this. The narrowing could reflect three decades of mainland underdevelopment finally correcting, a one-off catch-up, or the island reaching a ceiling set by buyer affordability. What is measurable is that mainland prices grew faster over 2019 to 2024 and that the mainland now holds the larger forward pipeline, which puts more of the absorption question on that side of the channel.
