Financial Reserve
What is Sinking Fund in Thailand?
The Definition
In Thailand, a sinking fund is a one-time reserve contribution required from buyers of new condominiums or villa projects, calculated per square meter of the unit (typically 400-800 THB/sq.m.), and managed by the Condominium Juristic Person (CJP) for major, infrequent expenses like structural repairs, elevator replacements, or repainting. It differs from monthly maintenance fees, which cover routine upkeep, as the sinking fund targets long-term capital improvements and is non-refundable upon sale.
Global Expectations vs. Thai Reality
Western buyers might expect a sinking fund to be refundable upon resale or proportionally transferable like in some U.S. or European condo associations, but in Thailand, it's a permanent, non-refundable contribution to the project's collective reserve, with no automatic refund even if the fund is healthy. They may also anticipate strict legal mandates for separate bank accounts, yet Thai law does not require ring-fencing, relying instead on CJP transparency and owner oversight. Additionally, top-up collections for depleted funds are common in older developments via owner votes, unlike more rigid Western replenishment schedules.
The Problem It Presents
Buyers unaware of the non-refundable nature may face sticker shock at closing, adding 15,000-24,000 THB for a 30 sq.m. unit without recourse upon resale. In poorly managed projects, funds can be depleted without transparency, leading to unexpected top-up votes that strain budgets. Secondary buyers of resales often skip the initial payment (as originals contributed), but inherit depleted reserves, risking future calls for replenishment.
Foreigner vs. Thai Citizen Rules
Sinking fund rules apply equally to Thai citizens and foreigners owning condos (limited to 49% foreign quota per building), with identical per-sq.m. contributions required on new purchases. Differences arise indirectly via ownership limits—foreigners cannot own land-based villas outright, restricting sinking funds mainly to condos—while both must adhere to CJP decisions on usage or top-ups.
The Thai Legal Context
The sinking fund is governed by the Condominium Act B.E. 2522 (1979), as amended, which mandates its establishment for condo projects and assigns management to the CJP formed post-construction. The Department of Lands oversees title transfers where the contribution is verified, while the CJP handles collection, reporting, and usage via annual owner meetings; no specific AMLO or Revenue Department rules apply directly beyond general financial transparency.
Benefits & Risks
Advantages
- Ensures funds for major repairs (e.g., roofs, elevators), protecting property value without special assessments.
- One-time payment avoids ongoing fees, stabilizing long-term ownership costs.
- Developer covers unsold units, building a healthy initial reserve.
Risks & Disadvantages
- Non-refundable, even on sale, reducing net proceeds.
- No legal mandate for separate accounts, risking mismanagement.
- Top-ups possible via owner vote if depleted, creating unpredictable costs.
Showcase: How It Works
Let’s look at a real-world scenario to understand how Sinking Fund is applied during a property transaction.
The Scenario
- A foreign expat buys a new 50 sq.m. studio condo in Phuket for 5 million THB.
- The project charges a sinking fund rate of 600 THB per sq.m. due at transfer.
- Five years later, the CJP votes to use 20% of the pool for elevator upgrades.
The Result
The buyer pays 30,000 THB (50 x 600) directly to the CJP at closing. This one-time payment secures the building's long-term health. When repairs are needed years later, no top-up is required because the reserve is healthy.
Outcome: 30,000 THB One-Time Payment

Why It Matters
Ignoring the sinking fund can erode your investment through surprise top-ups or value loss from unmaintained buildings; always verify rates and CJP health to ensure long-term stability.
💡 REMAX Pro Tip
Before signing, demand the latest CJP balance sheet and insist on a separate ring-fenced account clause in negotiations—REMAX agents access developer projections to flag underfunded projects early.
