Navigating Koh Samui’s Holiday Rental Market: Already preparing for Low Season 2026?

As Koh Samui’s Low Season 2025 unfolds, the island’s holiday rental market is at a critical juncture. A massive influx of new developments and properties is flooding the market, signaling a potential crash in Low Season 2026. At Siam Commercial Service, we’re already preparing for this shift, implementing a mid-term strategy to ensure our clients’ properties remain competitive. By focusing on reputation, visibility, and adaptability, we help property owners navigate market fluctuations with confidence—whether their goal is pure investment or a balance of personal use and returns.

The Evolving Reality of Koh Samui’s Holiday Rental Market

This Low Season 2025, we’ve seen the early signs of a changing market. The summer of 2025 achieved decent occupancy rates in July and August, but bookings arrived late—often at the last minute—forcing nightly rates to drop to levels that surprised many property owners. This isn’t a temporary blip; it’s a clear indication of supply outpacing demand. With dozens of new properties entering the market, competition is intensifying, and we anticipate even greater challenges in Low Season 2026 (April to November). The days of relying on high nightly rates are fading, and a strategic, forward-thinking approach is now essential.

A Mid-Term Strategy for Succes

At Siam Commercial Service, we view Low Season 2025 as a critical preparation period for the anticipated challenges of Low Season 2026. Our mid-term strategy—spanning several months—focuses on building a strong foundation for your property to thrive in a competitive market. The months of September to November 2025 are not just a lull; they’re an opportunity to accumulate guest reviews, boost occupancy, and enhance your property’s reputation. This approach ensures your property enters the Peak and High Seasons with maximum visibility on Online Travel Agency (OTA) platforms like Airbnb and Booking.com, where algorithms reward consistent bookings and positive feedback.

Long-Term Rentals: A Stable Alternative

While the short-term rental market faces increasing pressure, long-term rentals remain a resilient option. Koh Samui’s growing expat community, supported by improvements in healthcare and international schools, is driving demand for long-term leases. We’re seeing clear “bubbles” of interest around areas near top-tier international schools, making these properties attractive for investors seeking stable returns. However, not every property is suited for long-term rentals, and factors like location and tenant needs must align. Our team at Siam Commercial Service tailors strategies to each property’s unique attributes, ensuring optimal results.

Balancing Owner Goals: Investment, Preservation, and Personal Use

Every property owner has unique goals, and at Siam Commercial Service, we adapt to them all. For owners prioritizing pure investment, our strategy is clear: prioritize occupancy and reputation over inflated nightly rates to achieve a strong return on investment (ROI)—whether that’s 10% or another target. Chasing rates 20–30% above market value risks vacant properties and missed opportunities, especially as competition grows.

However, we recognize that many owners also value property preservation or personal use. Some prefer to keep their property available for family vacations or personal retreats, which may influence their rental strategy. Our team is flexible, working closely with owners to balance these priorities while maximizing returns. Ultimately, the owner is king and has the final say on how their property is managed. Our Team is always available to provide the data, insights, and expertise to inform those decisions, ensuring alignment with your vision.

Why Reputation and Visibility Matter More Than Ever

In a market heading toward a potential crisis in Low Season 2026, building a strong reputation is your greatest asset. Here’s why:

- Low Season as a Foundation: September to November 2025 is a critical time to secure bookings, gather positive reviews, and boost your property’s ranking on OTA platforms. This visibility sets the stage for success in Peak and High Seasons.

- Preparing for a Crisis: The influx of new properties signals that Koh Samui’s holiday rental market may face significant challenges sooner than expected. Properties with strong reputations and high visibility will remain resilient, even in a downturn.

- Focus on ROI, Not Nightly Rates: A high nightly rate in Low Season is tempting but risky. A strategic approach—prioritizing occupancy and guest satisfaction—delivers better long-term results.
