Phuket Property ROI: Calculate Real Returns on Condos & Apartments

Why ROI in Phuket Must Be Calculated Mathematically, Not from Brochures

Investing in apartments and condos in Phuket is one of the most frequently miscalculated property models in Asia. The reason is simple: ROI rarely fails at the purchase price, but almost always fails later—on operational costs, seasonality, and unrealistic occupancy assumptions.

Phuket is a mature, tourism-driven, and highly competitive market. This means rates are transparent, costs are predictable, and mistakes… are repeatable. This article presents a simple, replicable ROI calculation model that can be applied to any apartment or condo—without promises of "guaranteed rental returns."

Phuket in 30 Seconds: The Most Important ROI Fact

The most important fact about ROI in Phuket is this:

High gross income does not equal high net ROI.

The ROI Model – What to Calculate and What You Cannot Ignore

A realistic ROI model for Phuket consists of five elements:

capital expenditure (CAPEX),
gross income,
seasonality and occupancy,
fixed costs (OPEX),
vacancy and depreciation reserves.

Any model that omits any of these points is not an investment model, but a sales calculator.

CAPEX: Real Entry Cost, Not the Listing Price

A typical mistake is calculating ROI based solely on the purchase price. Meanwhile, the real entry capital for an apartment or condo in Phuket includes:

property price,
transfer taxes and fees,
legal costs and due diligence,
furnishing and operational startup.

Typical ranges (1BR condo):

purchase price: 4,500,000 – 7,000,000 THB,
transaction fees: 3–5% (135,000 – 350,000 THB),
legal and DD costs: 40,000 – 80,000 THB,
furnishing + startup: 180,000 – 350,000 THB.

Total CAPEX: very often +7–10% above purchase price.

Gross Income – Where Investors Inflate the Numbers

Phuket has clear seasonality. Average daily rates cannot be multiplied by 365 days.

Realistic ranges (1BR condo):

high season (November–March):
2,800 – 4,500 THB / night,
low + shoulder season:
1,600 – 2,500 THB / night.

Average annual occupancy for well-located condos:

conservative: 45–50%,
aggressive: 55–60%.

Any assumption above 65% requires very strong justification.

Gross Income Example – Realistic Scenario

Assumptions:

average annual rate: 2,600 THB,
occupancy: 52% (190 nights).

Gross income:

2,600 × 190 = 494,000 THB / year

This is the number from which real ROI calculation begins.

OPEX: Costs That Eat Into Returns

Operating costs in Phuket are repeatable and predictable, but often underestimated.

Typical OPEX (annual):

rental management: 20–30% of income (99,000 – 148,000 THB),
HOA fees: 40–70 THB/m²/month (25,000 – 45,000 THB),
electricity, water, internet: 30,000 – 45,000 THB,
maintenance / minor repairs: 25,000 – 40,000 THB,
insurance: 5,000 – 10,000 THB.

Total OPEX: very often 170,000 – 260,000 THB annually.

Vacancy and Depreciation Reserve – The Element That Determines Stability

A professional ROI model always includes:

vacancy reserve: 5–8% of income,
depreciation / refurbishment reserve: 20,000 – 40,000 THB / year.

Without this reserve, ROI only looks good on paper.

Net ROI – Complete Calculation Example

Assumptions:

CAPEX: 6,200,000 THB,
gross income: 494,000 THB,
OPEX + reserves: 260,000 THB.

Net result:

234,000 THB / year

Net ROI:

~3.8%

This is an honest, conservative result for a standard condo in Phuket.

How to Achieve 6–8% ROI – What Actually Makes a Difference

Higher ROI in Phuket doesn't come from magic, but from a combination of four factors:

good location (demand outside high season),
reasonable CAPEX (no overpaying for design),
mix of short + mid-term rentals,
management cost control.

Well-optimized projects achieve 6–8% net ROI, but these are not mass-market offerings.

The Most Common Myth About ROI in Phuket

"If there's tourism, it will always rent out."

The market rents functional products, not just addresses.

3 Facts You Must Know: ROI in Phuket

ROI fails on costs, not on rates.
Seasonality determines result stability.
The best ROI comes from "boring" projects, not lifestyle ones.

Investor Checklist: ROI in Phuket (5 Points)

Is ROI calculated on a net basis, not gross?
Is occupancy realistic outside high season?
Can CAPEX be justified by rental income?
Does OPEX include management and reserves?
Will the project hold up in a weaker market?

If you can't answer one question—ROI hasn't been properly calculated.

Summary: ROI in Phuket Is Discipline, Not a Promise

Phuket allows you to earn from apartments and condos, but only for investors who calculate without illusions. Real returns don't come from sales presentations, but from cost control, seasonality management, and entry capital.

ROI doesn't "work itself out."

ROI must be engineered.
