The price listed on a developer's website is only the starting point of your budget. The final amount you pay is almost always higher.
There is usually a gap between the advertised price and the actual cost at closing. Phuket is no exception. Based on the majority of transactions, buyers should expect an additional 3–5% of the property's value in closing-related expenses. For many purchases, that means tens of thousands of dollars that never appear in the marketing brochure.
Developers are generally not hiding these costs. They simply don't include many standard transaction expenses in their sales presentations. However, these are exactly the costs that make up the real purchase budget—and you should understand them before signing the contract, not afterward.
Who Pays the Transfer Fee?
When ownership is registered with the Land Department, both the buyer and the seller are required to pay a property transfer fee, which equals 2% of the government's assessed property value.
In most developer agreements, this fee is split equally, with each party paying 1%.
Some developers choose to cover the entire transfer fee as a marketing incentive, but this should always be confirmed in advance. The exact terms are specified in the Sale and Purchase Agreement (SPA), so the SPA should be reviewed carefully before signing.
Example: For a property priced at $300,000, the buyer's share of the transfer fee is typically $3,000–6,000. While this is not a major expense compared to the purchase price, it is rarely included in the advertised price.
A Property Lawyer Is Not Optional
Hiring an independent property lawyer is an essential part of any real estate transaction in Thailand.
A lawyer verifies:
ownership of the land;
the developer's legal standing and reputation;
construction permits;
and, most importantly, the terms of your Sale and Purchase Agreement.
Without legal review, buyers often sign contracts without fully understanding the obligations and restrictions they are accepting.
Legal due diligence typically costs $1,500–3,000. Compared to the potential cost of contractual mistakes, this is a relatively small investment.
A legal review often uncovers issues such as:
restrictions on future resale;
unclear leasehold renewal provisions;
vague construction deadlines;
other clauses that may significantly affect your investment.
Once the contract has been signed, correcting these issues becomes considerably more difficult and expensive.
Furnishing: The Expense Buyers Often Forget
Most newly completed developments in Phuket are delivered either unfurnished or with only a basic furniture package.
If you're purchasing the property as a short-term rental investment, it cannot generate income without proper furnishing. Although this seems obvious, furnishing costs are frequently overlooked when buyers calculate their initial budget.
Professional furnishing suitable for the vacation rental market typically costs $10,000–25,000, depending on the size and quality of the property.
The quality of the furniture and the property's listing photos has a direct impact on rental performance. Within the same location, a professionally designed apartment can achieve 30–40% higher average nightly rates than a minimally furnished alternative.
Sinking Fund and First-Year Maintenance Fees
When taking possession of the property, buyers in most Phuket developments are required to make a one-time contribution to the sinking fund.
This reserve fund is managed by the property's management company and is used for future major repairs and replacements, including swimming pools, elevators, roofing, and other shared facilities.
At the same time, buyers are usually required to pay the first year's maintenance fees in advance.
Together, these payments typically total $2,000–5,000.
Unlike ongoing maintenance costs, these fees become payable immediately upon receiving the keys, making them one of the most commonly overlooked expenses in the purchase process.
What "Guaranteed 8% Rental Return" Really Means
Many Phuket developments advertise "8% guaranteed annual returns."
In most cases, this figure refers to gross yield—the rental income before expenses.
The actual net return is considerably lower.
After deducting:
property management fees (typically 20–30% of rental revenue for short-term rentals),
utilities and operating expenses,
and seasonal fluctuations in occupancy (May through October, when occupancy can fall to 30–55%, with August to October generally being the weakest months),
the realistic net rental yield is usually 4–5.5%.
Well-located properties managed by experienced operators may achieve up to 6% net yield.
Even after accounting for these costs, Phuket remains one of Southeast Asia's stronger property markets. Rental income, long-term capital appreciation (for example, Bang Tao recorded approximately 35–40% price growth between 2019 and 2024, while growth during 2023–2025 moderated to around 8% annually), and lifestyle appeal create a combination that is relatively uncommon across the region.
The key is to evaluate investments using realistic financial projections—not marketing brochures.
A Simple Rule of Thumb
Plan to budget an additional 10–12% on top of the property's purchase price to cover closing costs and initial ownership expenses.
This is standard market practice.
Cost Breakdown for a $300,000 Property
Transfer fee (buyer's share, approximately 1%): $3,000–6,000
Legal due diligence: $1,500–3,000
Professional furnishing for short-term rental: $10,000–25,000
Sinking fund and first-year maintenance fees: $2,000–5,000
Total additional costs: $16,500–39,000
As a result, the true acquisition cost of a $300,000 property is typically between $316,000 and $339,000, depending on the development and your investment strategy.
The wide range is primarily driven by furnishing costs, which are variable. If you are buying the property as a personal residence rather than as a rental investment, furnishing for short-term rental may not be necessary, significantly reducing the overall upfront budget.
