Phuket: Hidden Costs of Apartments and Condos – Fees, Sinking Fund, Maintenance & Insurance (Real Numbers)

Phuket: Hidden Costs of Apartments and Condos – Why They Determine Your Margins

In the Phuket real estate market, the purchase price attracts the most investor attention. This is a mistake. The real investment outcome is determined by recurring costs that appear every month and every year, regardless of whether the apartment is rented or sitting vacant.

Hidden costs aren't "extras." They systematically erode your margins and very often determine whether your ROI is 8%, 5%… or drops below the profitability threshold.

This article breaks down all key operating costs for apartments and condos in Phuket – no marketing fluff, just real market rates.

Why Phuket Is Particularly Sensitive to Fixed Costs

Phuket is a market that is:

• tourism-driven and seasonal,
• price-competitive,
• based on condos and apartments with common areas,
• requiring intensive maintenance (climate, humidity, heavy usage).

This means that building and operational costs have a greater impact on ROI than the purchase price itself.

Common Area Fees – A Fixed Cost You Cannot Avoid

The common area fee is the basic monthly cost for every condo in Phuket.

Current Market Rates (2025–2026)

• standard projects: 55–75 THB / m² / month
• resort-style / premium projects: 80–110 THB / m² / month

Example:

A 45 m² apartment in a premium project:

90 THB × 45 m² × 12 months = 48,600 THB annually

The fee covers:

• security,
• reception,
• swimming pools and gym,
• common areas,
• basic infrastructure maintenance.

It does not cover repairs inside your unit.

Sinking Fund – The Cost Most Investors Forget

The sinking fund is a one-time payment, but it significantly impacts your entry cost.

Typical Rates in Phuket

• 500 – 1,200 THB / m² (payable at purchase)

Example:

45 m² × 1,000 THB = 45,000 THB

This fund is used for:

• façade renovations,
• infrastructure upgrades,
• elevator replacement,
• common area refurbishments.

If the fund is too low – special assessments will be required in the future.

Utilities – Costs Highly Dependent on Rental Model

Electricity

• building rate: 5.0 – 7.0 THB / kWh
• short-term rental usage: 3,000 – 6,000 THB / month
• long-term rental (tenant pays): 0 THB for owner

Water

• 25 – 45 THB / m³
• average: 300 – 700 THB / month

Internet

• 600 – 1,200 THB / month

Service and Maintenance – Costs That Grow Over Time

Phuket has a tropical climate. This means:

• air conditioning runs year-round,
• humidity destroys seals and electronics,
• furniture and appliances wear out faster.

Average Maintenance Costs

• AC servicing: 1,200 – 2,000 THB / unit
• minor annual repairs: 15,000 – 30,000 THB
• wear-and-tear reserve: 20,000 – 40,000 THB / year

Total: 35,000 – 70,000 THB annually

Property Insurance – Small Cost, Big Significance

Insurance isn't mandatory, but skipping it is an investment mistake.

Approximate Rates

• property insurance (condo): 0.08–0.15% of value annually
• apartment valued at 5,000,000 THB → 4,000 – 7,500 THB / year

Protection covers:

• water damage,
• fire,
• installation damage,
• liability.

Hidden Cost #1: Vacancy

Every month without a tenant means:

• 100% of fixed costs,
• 0% income.

With fixed costs at 12,000 – 18,000 THB / month, even 2–3 months of vacancy can reduce ROI by 1–1.5 percentage points.

Phuket in 30 Seconds – The Most Important Fact

In Phuket, fixed costs matter more than rental rates.

The Most Common Myth About Phuket

"These are just minor fees."

No. This is systematic margin drainage if not calculated from the start.

3 Facts You Must Know

1. Common fees rise faster than rents.
2. A low sinking fund means future special assessments.
3. ROI calculated without fixed costs is fiction.

1. What is the actual common fee rate per m²?
2. Is the sinking fund adequate?
3. Who pays utilities under the rental model?

Summary: Fixed Costs Determine Your Returns
