Ask around and you will hear Koh Samui villa yields quoted at 10, 12, even 15 percent. It is worth being clear about what those numbers leave out, because the gap between an advertised gross yield and the money that actually reaches you is where investors get disappointed.
Key takeaways
- Advertised yields are almost always gross. The realistic net figure on Koh Samui is mid-single digits to around 8 percent.
- Professional villa management alone takes 20 to 30 percent of rental income.
- Yield follows occupancy, and occupancy follows location. The east coast leads for short-term lets.
- Short-term holiday letting needs the right licence. Long-term letting does not.
Gross versus net: the number that matters
A gross yield is rental income divided by purchase price, before any costs. A net yield is what is left after management, maintenance, utilities, taxes and vacancy. On Koh Samui the realistic net figure for a well-located, professionally managed villa sits in the mid-single digits to around 8 percent, not the double-digit headline.
Here is the same villa, shown two ways. The gross looks like a strong investment. The net is the number you actually live on.
| Line | Gross view | Net reality |
|---|---|---|
| Headline yield | 12% | 12% |
| Management (25%) | Not shown | − 3.0% |
| Maintenance, pool, garden | Not shown | − 1.5% |
| Utilities, insurance, fees | Not shown | − 1.0% |
| Low-season vacancy | Not shown | − 1.5% |
| What reaches you | 12% | ~5% |
Any projection built on peak-season rates alone, applied across a whole year, is telling you a story rather than a number.

What eats into the gross
None of these are optional if you want the property to perform. Together they are the entire difference between the gross and the net.
- Management: 20 to 30 percent of rental income for a professionally run villa.
- Pool and garden: steady monthly upkeep in a climate where both need constant attention.
- Utilities: air conditioning through the hot season is the big driver of the electricity bill.
- Vacancy: the weeks the villa sits empty in low season, which the headline yield ignores.
- Insurance and fees: building insurance, and common area fees in a managed development.
Location drives occupancy
Yield follows demand, and demand follows location. Match the area to the strategy rather than chasing a headline number.
| Area | Rental character | Best for |
|---|---|---|
| Chaweng | Highest short-term occupancy | Holiday-let yield |
| Chaweng Noi | Strong, quieter, better beach | Balanced yield |
| Bophut | Strong, airport and village nearby | Short and long term |
| Maenam | Steady long-term demand | Long-stay rental |
The licensing point
Long-term letting is straightforward. Short-term holiday letting is commercially common but sits in a grey area under Thai hotel licensing rules unless the property holds the right licence. A yield projection that assumes nightly holiday lets should also account for how the property is licensed to operate.
How we model a real return
When we quote a return on a specific property, it is based on twelve months of realistic occupancy, not a peak week, and we show you the assumptions behind the number. Browse our villas for sale, or tell us your target yield and we will be honest about what is achievable.
Frequently asked questions
What rental yield is realistic on Koh Samui?
A realistic net yield for a well-located, professionally managed villa sits in the mid-single digits to around 8 percent, after management, maintenance, utilities and vacancy. Double-digit figures usually quote gross, not net.
Why is the net yield lower than the advertised yield?
Advertised figures are usually gross. Professional management alone takes 20 to 30 percent of income, and pool, garden, staff, utilities, insurance and low-season vacancy reduce it further to the net figure you actually receive.
Which areas give the best rental returns?
The east coast around Chaweng and Chaweng Noi has the highest short-term occupancy, and Bophut performs strongly. Quieter areas like Maenam suit steady long-term rental rather than high short-term yields.
Do I need a licence to rent my villa out?
For long-term letting, no. For short-term holiday letting, the property needs the correct licence to operate within Thai hotel rules. We will tell you which category a given property falls into.
