Two different markets with different ideas

Phnom Penh is the country's capital, with a business, diplomatic, and financial center. Sihanoukville is a coastal city, a seaport, a gaming zone, and a growing logistics hub. Both markets are active, but the investment logic in them differs fundamentally.

Phnom Penh: liquidity and infrastructure

The capital is developing faster than the coastal destinations — it is here that the main properties built to international standards are concentrated. The BKK1 district — a business center with 40+ banks and 29 embassies — trades at $3,000–3,500/m² in completed projects. The adjacent districts (BKK3, Toul Kork) offer a lower entry point.

  • A wide selection of properties: from budget options from ~$1,100/m² to luxury from $3,000/m²
  • A high concentration of expat tenants: diplomats, managers of international companies, NGO staff
  • Rent for a 1BR in BKK1: $700–1,800/month
  • Developed infrastructure: international schools, shopping malls, healthcare
  • The new Techo Airport opened in September 2025 — a direct driver of prices

Sihanoukville: sea, port, specifics

Sihanoukville's main bet is its seaport, which by 2030 is expected to handle 2.5+ million TEU. Highly qualified expat specialists with long-term contracts will arrive for the port projects — and all of them need rentals in quality complexes. In parallel, 190 casinos operate, providing a steady tourist flow from Asia.

  • Beachfront prices — $1,084–1,500/m² at the start (forecast of $3,000/m² by completion)
  • Freehold properties are extremely scarce — Sihanoukville is in most cases leasehold; freehold is concentrated predominantly on Otres Beach
  • Secondary market liquidity is lower than in the capital
  • The city's atmosphere is noticeably oriented toward the Chinese market — the European segment is concentrated on Otres Beach

Risks across both markets

In Phnom Penh, the main risk is the choice of developer and specific property: not all districts are equally liquid. In Sihanoukville — frozen construction projects after COVID (experts recommend avoiding the secondary market of unfinished projects) and concentration in the gaming sector, which is sensitive to regulatory changes.

Where the choice is simpler

If you are considering your first investment, Phnom Penh is preferable: more liquid properties with clear terms, a broader rental market, lower specific risks. Sihanoukville is for those who deliberately bet on the coastal destination and accept higher concentration risk in exchange for a potentially lower entry point and a seaside location.
