ROI in Sihanoukville: How to Calculate Real Returns on Condos (No Marketing)

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:

20–30% of short/mid-term revenue
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

If a project can't "breathe" at 60–70% of planned revenue, ROI is an illusion.

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. Can the project survive a 25–30% revenue drop?

If not — the risk is on your side.

Summary: When ROI in Sihanoukville Makes Sense

ROI in Sihanoukville isn't for everyone.

This is a market for investors who:

calculate conservatively,
accept cyclicality,
control costs instead of chasing narratives.

If you calculate realistically — the result holds up.

If you calculate "like in the brochure" — the market will correct it.
