What is off-plan property and how does it work in Thailand?

Buying off-plan property — investing in a condo or villa before it’s built — is a common option in Thailand’s real estate market. It allows buyers to secure a unit at a lower price and choose from the best layouts. But it also comes with specific processes and risks you need to understand.


🧱 What Does “Off-Plan” Mean?

Off-plan refers to buying property directly from a developer during the pre-construction or construction phase — based on floor plans, brochures, and 3D renders instead of a finished unit.

✅ You pay in stages as the project progresses
✅ You often get better prices than post-completion buyers
✅ Completion can take 1–3 years, depending on the project


🔄 How the Process Works

Here’s a simplified overview of the off-plan purchase journey in Thailand:

🧾 Red Flag Checklist

✅ Sales agreement is vetted by a lawyer
✅ Construction permits are in place
✅ Project has a clear completion date and penalties for delays


🛡️ Legal Protections for Buyers

Thailand has improved buyer protections in recent years, but you should still:

  • Hire an independent lawyer to review the contract
  • Check the developer’s registration with the Thai Department of Business Development (DBD)
  • Ensure installments are tied to construction milestones — not just calendar dates

📌 For condos, ensure the project is registered under the Condominium Act — giving foreign buyers the right to own freehold units (up to 49% of total space in a building).


🏁 Conclusion: Is Buying Off-Plan Worth It?

Yes, if you’re comfortable waiting 1–3 years and have a trusted developer
No, if you need immediate use or dislike uncertainty

It’s a great strategy for investors looking for capital gains or foreign buyers wanting the best deal. Just make sure to do due diligence, vet the developer, and read all contracts carefully.
