ROI in Sihanoukville: How to Calculate Real Returns on Apartments and Condos (Without the Marketing Hype)
Introduction: Why ROI in Sihanoukville Must Be Calculated Differently Than in Phuket or Phnom Penh
Sihanoukville is a cyclical, infrastructure-driven market heavily dependent on external factors. It's not a stable administrative capital like Phnom Penh, nor a mature tourist resort like Phuket. This means one thing: ROI on apartments and condos here doesn't stem from purchase price alone, but from a project's resilience to demand fluctuations.
In practice, this means:
- the same price per sqm can yield drastically different net results,
- occupancy rates are not constant throughout the year,
- operating costs erode ROI faster than investors assume on paper.
This article presents a realistic, repeatable ROI calculation model that can be applied to any Sihanoukville project, without marketing shortcuts.
Sihanoukville in 30 Seconds: The Most Important ROI Fact
ROI in Sihanoukville doesn't fail on rental rates, but on:
- vacancy periods,
- fixed costs,
- unrealistic seasonality assumptions.
If you don't calculate the weaker year scenario, you're not calculating ROI, you're calculating a wish.
The Most Common ROI Myth in Sihanoukville, Debunked
Myth: "Sihanoukville is recovering, so ROI will come automatically."
Reality:
Market recovery doesn't guarantee uniform demand. Capital and rental demand return selectively: to projects with good locations, sensible floor plans, and controlled costs.
ROI doesn't come from narratives, only from cash flow.
Step 1: Purchase Price and Real CAPEX (ROI Starting Point)
Purchase price (2025/2026 market, realistic ranges):
- condos in functional projects: $1,200-1,800/sqm
- premium beachfront projects: $2,000-2,800/sqm
Base example for further calculations:
- 1-bedroom apartment, 52 sqm
- price: $1,500/sqm
- purchase value: $78,000
Transaction costs (Cambodia):
- transfer tax: 4% of value → $3,120
- notary + registration: $300-600
- legal due diligence (recommended): $800-1,500
Entry CAPEX (excluding furnishing):
≈ $82,500-83,200
Step 2: Finishing and Furnishing Costs for Rental
This is one of the key ROI elements in Sihanoukville.
Functional standard (not showroom):
- finishing + furniture: $350-550/sqm
- for 52 sqm: $18,000-28,000
Why not cheaper?
Because cheap materials:
- deteriorate faster (coastal climate),
- generate more frequent repairs,
- lower rental rates faster than initial savings.
New total CAPEX:
≈ $100,000-111,000
Step 3: Rental Model, Short-Term vs Mid-Term vs Long-Term
In Sihanoukville, pure short-term rarely wins on stability.
Short-term (tourist):
- rate: $45-70/night
- realistic annual occupancy: 35-50%
- high seasonality
Mid-term (1-6 months):
- rate: $800-1,100/month
- occupancy: 65-80%
- lower turnover
Long-term (12 months):
- rate: $600-850/month
- occupancy: 85-95%
- lowest operating costs
In practice, the best ROI comes from a mid + long-term mix, not aggressive short-term.
Step 4: Gross Revenue, Calculated Realistically
Mixed scenario (conservative):
- 6 months mid-term: $950 × 6 = $5,700
- 6 months short-term (40% occupancy):
- $60 × 180 days × 40% = $4,320
Annual gross revenue:
≈ $10,020
Step 5: Operating Expenses (OPEX) That Determine ROI
Rental management:
- conservatively: $2,200/year
Building maintenance fees:
- $0.80-1.50/sqm/month
- 52 sqm → $500-900/year
Utilities (electricity, water, internet):
- $900-1,200/year
Service, minor repairs, reserve:
- $1,000-1,500/year
Total OPEX:
≈ $5,600-6,800/year
Net Result (Part 1, Without Emotion)
Gross revenue: ~$10,020
OPEX: ~$6,200 (mid-range)
Net income:
≈ $3,800 annually
With CAPEX of ~$105,000 this yields:
Net ROI ≈ 3.6%
And this is an honest starting point, not marketing.
Why This Is NOT a Bad Result (And Where Investors Make Mistakes)
ROI in Sihanoukville:
- is not a "flipping" market,
- is a cyclical market,
- requires cost control, not chasing rates.
Most disappointments stem from:
- ignoring vacancy periods,
- underestimating management costs,
- calculating ROI from "the best month".

Step 6: How to Realistically INCREASE ROI in Sihanoukville (Without Increasing Risk)
Increasing ROI in Sihanoukville isn't about raising nightly rates, but optimizing three elements: occupancy, fixed costs, and rental structure.
1. Shifting weight from short-term to mid-term
Rentals of 1-6 months (infrastructure project workers, managers, contractors) allow you to:
- reduce management commissions,
- limit turnover and cleaning costs,
- stabilize cash flow.
In practice:
- short-term: 25-30% operating costs,
- mid-term: 15-20% operating costs.
This difference increases net ROI by 0.8-1.2 percentage points without changing purchase price.
2. Reducing vacancy instead of fighting for rates
Instead of $70/night and 30% occupancy:
- $55-60/night,
- 45-50% occupancy.
The math is merciless, occupancy beats rate.
3. Controlling building costs
Differences in maintenance fees in Sihanoukville are enormous:
- efficient projects: $0.80-1.00/sqm/month
- "visual" projects: $1.50-2.20/sqm/month
For 52 sqm, that's:
- ~$500/year vs ~$1,300/year
- meaning 0.7-0.8% ROI difference with the same rent.
Adjusted ROI Scenario (Realistic, Defensible)
After corrections:
- greater mid-term share,
- better occupancy,
- lower OPEX.
New numbers:
- gross revenue: $10,800-11,200
- OPEX: $5,300-5,700
- net income: ~$5,000-5,500
With CAPEX of ~$105,000:
Net ROI: 4.7-5.2%
This is a realistic, repeatable result that can be defended in a weaker year.
Why 8% ROI in Sihanoukville Is a Warning Sign
If you see in an offer:
- "8-10% ROI guaranteed"
- "full occupancy year-round"
- "hands-off passive income"
that's not an investment model, it's a marketing projection.
To achieve 8% net on $105,000 CAPEX:
- net income would need to be ~$8,400/year,
- which with realistic costs means unrealistic occupancy or understated OPEX.
In practice, such projects:
- only work in the first year,
- then "fall apart" on costs and vacancies.
3 Facts You Must Know: ROI in Sihanoukville
Fact 1: ROI is a function of project resilience, not its price
Cheaper condos in poor locations can yield worse results than pricier but stable ones.
Fact 2: Mid-term rental is the market's backbone
Tourism returns in waves. 3-6 month contracts stabilize results.
Fact 3: Fixed costs determine survival in weak years
The Most Common Investor Mistake in Sihanoukville
Calculating ROI:
- from the best month,
- without vacancy periods,
- without service reserves.
This isn't analysis, it's optimistic narrative.
Investor Checklist: ROI in Sihanoukville (5 Verification Points)
1. Is ROI calculated NET, after all costs?
If not, the result is useless.
2. Is off-season occupancy realistic?
Check the 6-8 weakest months, not the best 3.
3. Does the maintenance fee stay below $1.20/sqm?
Above this threshold, ROI erodes quickly.
4. Does the model include mid-term, not just short-term?
No mid-term = no stability.
5. If not, the risk is on your side. ROI in Sihanoukville isn't for everyone. This is a market for investors who: If you calculate realistically, the result holds up. If you calculate "like in the brochure"the market will correct it.Summary: When ROI in Sihanoukville Makes Sense
