Sihanoukville Property Oversupply: 40,000 Empty Units and What It Means for Investors in 2026

Sihanoukville had 300,000 residents and more than 80 high-rise construction sites in 2019. Seven years later, the city has still not absorbed the supply released during that speculative boom. According to CBRE Cambodia estimates, between 35,000 and 42,000 residential units remain unsold or unoccupied across the market. For any international investor considering Cambodia, this is both a warning signal and a case study in how to read emerging markets.

The oversupply problem in Sihanoukville is not an abstract macroeconomic risk. It takes the form of concrete buildings - some finished, others abandoned mid-construction - lining Otres Beach Road and the port zone. Vacant units generate holding costs, and without tenants there is zero cash flow. Developers who counted on speculative Chinese capital are now sitting on assets for which local demand simply does not exist.

Quick answer

• Scale of the problem: between 35,000 and 42,000 unsold or vacant residential units in Sihanoukville (market estimates, 2025-2026)
• Root cause: a speculative boom driven by Chinese capital in 2016-2019, ended by the COVID-19 pandemic and the online gambling ban of 2019
• Current prices: down 40-60% from 2018-2019 peaks; units in unfinished projects offered at as little as 600-800 USD per sqm
• Vacancy rate: exceeds 70% in many condominium projects
• Gross rental yield: theoretically 3-5%, but only in a small number of completed, well-managed beachfront buildings
• Investor takeaway: entry requires extreme caution, thorough due diligence, and acceptance of a multi-year capital lock-up horizon

Options and scenarios

How did the Sihanoukville oversupply happen?

Between 2016 and 2019, Chinese developers and individual investors transformed the Cambodian coastal city into a construction site on a scale completely disconnected from the city's economic fundamentals. The engine was casinos, online gambling, and speculation - not tourism or organic population growth.

In August 2019, the Cambodian government banned online gambling. COVID-19 closed borders. Chinese capital withdrew almost overnight. What remained were tower skeletons, unfinished developments, and thousands of units with no buyers.

In 2026, the government under Prime Minister Hun Manet is attempting to reposition Sihanoukville as a logistics and tourism hub. A new expressway from Phnom Penh (completed 2023, 190 km, travel time reduced to approximately 2.5 hours) has improved connectivity. But residential demand still lags dramatically behind supply.

Scenario 1 - cautious recovery (most likely)

The government attracts infrastructure investment including a deep-water port and a special economic zone. Slow absorption of the oversupply will take 8 to 12 years. Prices remain at current depressed levels for the next 3 to 4 years, then gradually recover at 3-5% per year. An investor buying today at 700 USD per sqm could realistically target an exit at 1,000-1,200 USD per sqm around 2032-2034.

Scenario 2 - return of Chinese capital

A relaxation of Beijing's policy on outbound capital flows could revive demand. In this scenario prices would recover faster, but the risk of another speculative bubble would grow proportionally. Probability: low, given the current stance of the Chinese government on capital outflows.

Scenario 3 - further deterioration

Absence of government-backed investment, ongoing reputational damage linked to scam compound operations in and around the city, and physical degradation of abandoned buildings. Prices could fall a further 10-20%. An investor holding assets faces a loss of liquidity and no credible exit path.

Example calculation - condominium investment

Assume a purchase of a 45 sqm unit in a completed building near Otres Beach:

• Purchase price: 45 sqm x 800 USD/sqm = 36,000 USD
• Transaction costs (4% transfer tax, legal fees, due diligence): approximately 2,000 USD
• Total entry cost: 38,000 USD
• Monthly rental income (optimistic, short-term tourists or expats): 250 USD/month
• Annual gross rental income: 3,000 USD
• Gross yield: 3,000 / 38,000 = 7.9%
• Deduct: property management fees (15%), vacancy allowance (40% of the year), maintenance fees (approx. 50 USD/month)
• Net rental income after costs: approximately 1,200 USD/year
• Real net yield: 3.2%
• At zero capital appreciation and 3.2% net yield, the payback period from rental income alone exceeds 30 years

Conclusion: without capital appreciation, this investment does not make economic sense.

Risks and mistakes

1. Buying in an unfinished project. Dozens of buildings in Sihanoukville will never be completed. Developers went bankrupt or left the country. Funds paid under off-plan contracts are unrecoverable in most of these cases. The rule is non-negotiable: purchase only completed, occupied buildings with a verified title.

2. Missing a hard title. In Cambodia, a foreigner may own a condominium on a strata title (hard title) basis only above the ground floor, in a building with proper registration. Ground floor units and land require either a Cambodian company structure (with a local nominee shareholder holding at least 51%) or a long-term leasehold of up to 50 years with extension options. Many operators in Sihanoukville sold units without proper documentation.

3. City reputation. Sihanoukville became internationally associated with scam compound operations - enclosed complexes where trafficked individuals were forced to conduct online fraud. Government crackdowns are ongoing, but the stigma persists and directly affects tourism volumes and rental demand.

4. Lack of professional property management. Professional property management firms in Sihanoukville are scarce. Managing short-term rentals remotely from Europe (UTC+7, roughly 6-7 hours ahead of Central European Time) requires a reliable local partner. Without one, vacancy and maintenance problems escalate quickly.

5. Currency risk. Although Cambodia operates in US dollars (approximately 80% of real estate transactions are denominated in USD), European investors carry USD exposure relative to their home currency. A 10% strengthening of the dollar increases the effective cost of entry when measured in euros or British pounds.

6. Tax obligations in your home country. Income from overseas property rental is taxable in most European jurisdictions. Cambodia does not have double taxation treaties with the majority of European countries, which can complicate tax reporting. Always seek advice from a qualified tax advisor before committing.

7. Exit liquidity. This is the most serious risk of all. With vacancy rates above 70%, finding a buyer on the secondary market in Sihanoukville can take years. Resale discounts of 20-30% from already-depressed market prices are common.

FAQ

Is buying property in Sihanoukville a good investment in 2026?

For most international investors, the answer is no. The oversupply is too large, liquidity is too limited, and the payback horizon is too distant. The only defensible scenario is a cash purchase at an extremely low price (below 700 USD per sqm) in a completed building with a verified hard title, combined with full acceptance of an 8-to-12-year capital lock-up.

What do properties cost in Sihanoukville in 2026?

Prices range from around 600 USD per sqm for older buildings further from the beach to 1,200 USD per sqm for completed projects near Otres or Sokha Beach. Secondary market listings occasionally appear below 500 USD per sqm, but these typically involve units in buildings with legal or structural problems.

How can a foreigner legally own property in Cambodia?

A foreigner may own a condominium (hard title or strata title) only on floors above the ground level, in a building registered with the Ministry of Land Management. Ground floor units and land parcels require either a Cambodian company structure (at least 51% Cambodian shareholding) or a leasehold agreement of up to 50 years with a renewal option.

Will Sihanoukville recover as a real estate market?

Recovery is possible but realistic only over a decade-long horizon. Key factors include development of the deep-water port, growth of the special economic zone, increased connectivity via the Phnom Penh expressway, and a potential return of premium tourism. However, absorbing 35,000 to 42,000 vacant units requires a fundamental shift in demand structure, which takes significant time.

Is Phnom Penh a better investment than Sihanoukville?

Yes, by a wide margin. Phnom Penh has real economic fundamentals: a growing middle class, a rising international corporate presence, a population of approximately 2.5 million, vacancy rates below 25%, and rental rates that realistically cover costs. Gross yields of 5-8% at prices of 1,800-3,500 USD per sqm represent a significantly safer proposition.

What are the ongoing ownership costs in Sihanoukville?

Building maintenance fees typically run 0.80 to 1.50 USD per sqm per month. For a 45 sqm unit, that is 36 to 68 USD monthly. Add property tax (0.1% of assessed value above 25,000 USD), insurance, and occasional repairs. Total holding costs are roughly 80-120 USD per month, regardless of whether the unit has a tenant.

Is Cambodia's dollar-based economy an advantage for foreign investors?

Yes, in one important respect. Transacting in USD eliminates currency risk relative to the Cambodian riel (KHR) and simplifies asset valuation and international comparisons. However, European investors still carry USD exposure relative to the euro, the pound, or other home currencies.

What does a realistic exit strategy look like in Sihanoukville?

In 2026, the exit strategy is the most challenging part of any Sihanoukville investment. The secondary market is illiquid, qualified buyers are rare, and brokerage infrastructure is underdeveloped. Realistically, a sale may take one to three years and will likely require a price discount of 15-30% below current market valuations.
