30/70 Payment Plans in Phuket: How They Work and Who They Suit

In 2026, 70% of new-build properties in Phuket are sold under the 30/70 installment model. This is not a marketing gimmick — it is the standard financing structure that allows foreign buyers to enter a project with a modest upfront commitment and spread payments across the entire construction period.

The mechanics are straightforward: you pay 30% of the purchase price during construction, and the remaining 70% upon handover of the keys. No interest charges. No bank involvement. A direct contract with the developer.

For most international investors — who cannot qualify for a mortgage at a Thai bank — the 30/70 plan remains the primary route into the Phuket property market without requiring the full purchase amount upfront.

Quick Answer

• 30% is paid in staged installments during construction (typically 18–36 months)
• 70% is paid in a single transfer at handover
• Developer installment rate: 0% interest
• Reservation deposit to secure a unit: from 100,000 to 300,000 THB, depending on the project
• Thai bank mortgages for foreigners are available at only 2–3 institutions, with strict eligibility criteria
• An alternative exists — post-handover payment plans spreading the 70% over 3–5 years — offered by select large developers

Scenarios and Options

Scenario 1 — The Classic 30/70 Structure

You purchase a condominium priced at 5,000,000 THB. At contract signing, you place a reservation deposit of 100,000 THB. Over the following 24 months of construction, you pay the remaining portion of the 30% in equal monthly installments — approximately 58,000 THB per month. At handover, you transfer the final 3,500,000 THB.

The strategic advantage is clear: during construction, property values rise. Phuket market data from recent cycles shows off-plan condominiums appreciating 15–25% between launch and completion. You lock in today's price and pay the bulk of the cost two years later.

Scenario 2 — 40/60 or 50/50 Structures

Certain developers — particularly those offering premium villas priced above 15,000,000 THB — structure deals at 40/60 or 50/50 splits. A larger upfront commitment reduces the developer's risk and, in return, buyers can often negotiate a 3–5% discount off the list price. This format appeals to buyers with stronger liquidity who want to reduce the size of the final lump-sum payment.

Scenario 3 — Post-Handover Payment Plans

A less common but increasingly available format allows the 70% balance to be paid in installments over 3–5 years after the keys are handed over. Unlike construction-phase plans, this arrangement typically carries an interest charge of 5–7% per annum. Only a small number of well-capitalized developers offer this structure, and availability is project-specific.

Scenario 4 — Thai Bank Mortgage

Foreign nationals can theoretically obtain a mortgage in Thailand, but in practice eligibility is narrow. Banks such as UOB Thailand and ICBC Thailand will consider non-resident applications, primarily from holders of valid Thai work permits and verifiable income in Thailand. Interest rates run at 6–8% per annum, approved loan amounts rarely exceed 50% of the property value, and loan tenors reach up to 20 years. Expect the approval process to take 2–3 months.

Main Risks and Mistakes

1. No clear plan for the 70% final payment. The most common and costly mistake is entering a project without a concrete funding strategy for the balance due at handover. Some buyers count on selling their contract before completion — known as an assignment — but there is no guarantee the secondary market will cooperate on timing or price.

2. Skipping developer due diligence. A 30/70 plan only works if the developer delivers on time and to specification. Before signing anything, verify the project holds a valid EIA (Environmental Impact Assessment), a current construction permit, and a documented track record of completed developments. Review any available financial disclosures.

3. Confusing freehold and leasehold title. Foreign nationals can own a condominium unit outright (freehold), but only within the building's 49% foreign ownership quota. Villas, by contrast, are almost always structured as long-term leases (leasehold: 30 + 30 + 30 years). The payment plan structure does not change the ownership format — this needs to be understood before signing.

4. Currency exposure. All payments are denominated in Thai Baht. If your home currency weakens against the Baht during construction, your final payment increases in real terms. Over recent years, the Baht has ranged from 33 to 37 per USD — a swing of roughly 12% that can translate into hundreds of thousands of Baht on a mid-range unit.

5. Underestimating transfer-day costs. Beyond the 70% balance, budget for: a land registration fee (typically 1% of the assessed value), a sinking fund contribution, and an initial maintenance fee payment. For a typical condominium unit, these additional costs commonly total 150,000–400,000 THB.

FAQ

Can I sell my unit before making the final payment? Yes — this is called an assignment of contract. Most developers permit it for a fee of 1–3% of the purchase price. Some restrict assignments until a specific construction milestone has been reached. Confirm the terms in your sales and purchase agreement before relying on this exit route.

What happens if I cannot pay the 70% at handover? You forfeit all funds already paid. Standard Thai developer contracts include a clause allowing the developer to retain all installments paid to date in the event of buyer default. There is no standard grace period — the terms are fixed in the contract and non-negotiable.

Is a 30/70 plan available for resale properties? No. Installment plans of this type are exclusive to the off-plan primary market. Purchasing a resale unit requires the full purchase price or external financing arranged independently.

What documents do I need to enter a payment plan? A valid passport is the minimum requirement. Some developers also request proof of address (a utility bill or bank statement). Proof of income, tax returns, and employment records are not required for the installment itself.

Do I need a Thai bank account? Yes — and this is a legal requirement, not merely administrative. The final payment must be transferred through a Thai bank account and accompanied by a Foreign Exchange Transaction Form (FET). Without this document, you cannot register freehold title to a condominium unit at the Land Department.

Can I pay with cryptocurrency? Not officially. Some developers accept crypto on an informal basis, but doing so creates legal complications at the title registration stage and prevents you from obtaining the FET form required for freehold ownership.

How does a 30/70 plan differ from a mortgage? A developer installment plan is a private agreement between buyer and developer — no bank, no interest, and no asset valuation required. A mortgage is a bank loan secured against the property, subject to credit assessment, interest charges, and a formal valuation process.

Can I negotiate a different payment structure? Often, yes — particularly during early launch phases when developers have more flexibility. Buyers can request smaller or more frequent tranches within the 30%, or offer a larger upfront payment in exchange for a price discount. Negotiation is a normal part of the Phuket off-plan buying process.

What is the minimum budget to enter a 30/70 plan in Phuket? Studio units from 3,000,000 THB are available in areas such as Nai Harn and Rawai. With a reservation deposit of 100,000 THB and a first installment from approximately 50,000 THB per month, the entry requirement is roughly 150,000–200,000 THB — equivalent to approximately $4,000–5,500 USD.

Practical note: Before committing to a 30/70 plan, build a complete financial schedule covering the full construction period. Confirm you have a credible, specific source for the 70% final payment — whether personal savings, proceeds from other assets, or a documented assignment strategy. Have a qualified local lawyer review the contract, and open your Thai bank account before the process begins.
