Phnom Penh and Sihanoukville are the two markets foreign buyers ask about most, and they could hardly be more different in risk. One is the deep, liquid, already-repriced capital; the other is the country’s highest-variance market, mid-recovery from a spectacular boom and bust. Choosing between them is really a question about your risk appetite. This head-to-head sets them side by side; for the depth on each, read the Phnom Penh market guide and the Sihanoukville guide, and for the national backdrop, our mid-2026 outlook. Citations are marked [S-NNN]; the source list is at the end.

The one-line version

  • Phnom Penh is the lower-variance choice: the deepest market in the country, a real and diversified tenant pool, modest but genuine yields, and an achievable exit — supply has already reset prices, and the market is grinding toward stability.
  • Sihanoukville is the high-variance choice: apparent bargains among distressed and half-finished stock, but extreme volatility, a shallow and uncertain demand base, and a hard exit — deep value or deep trap, depending entirely on a recovery that is not guaranteed.

Market depth and liquidity

This is the starkest difference. Phnom Penh is the only genuinely deep residential market in Cambodia — roughly 60,000 condo units at end-2024, heading toward ~85,000 by 2027 [S-026], with citywide occupancy holding in the high-70s to low-80s percent [S-027]: the most stock, the most buyers, the most renters, and therefore the most realistic resale. Sihanoukville is thin and distorted — on the order of 360–400 stalled, unfinished towers downtown, with an estimated $1 billion or more needed just to complete them [S-034] [S-035], and counts that run far higher province-wide [S-036] — with a buyer pool that evaporated when the speculative money left. In Phnom Penh you can plan an exit; in Sihanoukville you must assume one may be slow, partial, or absent.

Risk and volatility

Phnom Penh’s big correction — condo oversupply — has largely already happened: prices in 2025 sat 15–20 percent below the 2019 peak and the market is working through it rather than bracing for it [S-026]; that makes it comparatively predictable. Sihanoukville is the opposite: its fortunes swung violently with Chinese casino capital — the 2019 online-gambling ban emptied an estimated 120,000 Chinese nationals out of the country in weeks, and Sihanoukville commercial rents collapsed [S-037] — and its “third act” (port, SEZ, tourism revival) is a real but unproven thesis: the government’s revival programme has approved hundreds of projects worth $8 billion-plus on paper, but how much capital has actually deployed remains unclear [S-034]. One is a repriced primary market; the other is a single-driver bet on a turnaround.

Tenant pool and demand

  • Phnom Penh has diversified, durable demand — expats, professionals, embassies, NGOs, a growing local middle class — across the city’s neighbourhoods. It doesn’t depend on any one industry.
  • Sihanoukville has shallow, volatile demand tied to tourism, the port, and the SEZ — more transient, more cyclical, and far easier to misjudge from a high-season or boom-era snapshot.

Price and yield

On paper, Sihanoukville looks cheaper — and some distressed stock genuinely is — but the discount is priced for the risk and the vacancy that come with it. Phnom Penh’s repricing has nudged gross yields up to modestly attractive levels on a far more reliable income base; the gap between gross and net still governs (see rental yields). Compare the current numbers side by side in the Cambodia Price & Yield Index, and read a Sihanoukville “bargain” as risk-loaded rather than free money.

Stock and condition

Phnom Penh offers modern, completable condo stock plus landed property across established districts. Sihanoukville’s defining feature is the half-finished tower — completion risk, quality risk, and orphaned buildings are everywhere, so the condition and status of the specific asset matter even more than the market call.

Catalysts and upside

Both have catalysts; weigh them differently. Phnom Penh benefits from steady urbanisation and its role as the expressway hub — incremental, reliable (see the expressway corridors guide). The two cities are now two to three hours apart on the $2 billion expressway opened in 2022 [S-038] [S-096], which helps both — but helps the established market more predictably. Sihanoukville’s upside is larger but speculative: port expansion, the SEZ, the expressway terminus, government revival plans, and the 2025–26 crackdown that closed hundreds of scam operations and dozens of casinos [S-034] could re-rate it — or not. Never pay today for Sihanoukville’s announced-but-unbuilt future; if it arrives it’s upside, not the thesis.

The verdict

  • Choose Phnom Penh if you want a lower-risk, liquid market with diversified demand, a realistic exit, and modest reliable yield or an owner-occupier home — which describes most foreign buyers.
  • Choose Sihanoukville if you are a high-risk-tolerant value hunter who can hold for years, do extreme asset-level diligence, and stomach the chance the recovery stalls — with capital you can afford to lock up or lose.
  • Default to Phnom Penh unless you specifically know why you’re taking the coastal bet. Sihanoukville is an expert’s market, not a first purchase.

Before you commit

  • Get the ownership path right — the buying process for a condo, or the holding structure for land, applies in both.
  • In Sihanoukville, vet the specific building hardest — completion status, title, and who is actually behind (and funding) the project.
  • Underwrite on net yield and realistic vacancy in both — and with extra conservatism on the coast.
  • Match the market to your risk appetite, not to the bigger headline discount.

The takeaway

Phnom Penh and Sihanoukville aren’t really competing for the same buyer. Phnom Penh is the deep, liquid, already-repriced capital — the sensible default for most foreign buyers who want diversified demand and an exit. Sihanoukville is the highest-variance market in the country — capable of deep value for an expert who can hold through an uncertain recovery, and capable of trapping anyone who mistook a discount for a bargain. Pick by risk appetite, do the asset-level homework the coast demands, and when in doubt, the capital is the lower-variance call. None of this is investment or legal advice; verify the current detail with a qualified local professional before you act.
