Direct answer
Neither new development nor resale is inherently better. New property may offer staged payments, current finishes, and choice, but introduces completion, specification, and developer risk. Resale provides a physical unit and operating history, but may carry defects, arrears, ageing systems, or unrealistic asking prices. Compare verified all-in costs and evidence.
Key takeaways
- 1.Compare completed evidence, not brochure features.
- 2.New-build risk centres on delivery; resale risk centres on existing condition and records.
- 3.Use independent contracts, title checks, inspections, and building-finance review for both.
- 4.Advertised discounts and asking prices do not establish value.
Important terms
Primary sale — Purchase from a developer or initial seller.
Resale — Purchase from an existing owner.
Snagging — Inspection and documentation of defects before acceptance.
Comparable evidence — Relevant completed sales or leases adjusted for material differences.
Detailed answer
New developments let buyers select layouts and may spread payments, but a promise must become a completed, approved, transferable asset. Review land ownership, finance, approvals, developer history, construction progress, specifications, variation rights, delay remedies, deposit protection, inspection, and transfer conditions.
Resale lets the buyer inspect the actual unit, common areas, occupancy, management, accounts, and bills. It also exposes historic alterations, deterioration, arrears, disputes, tenant rights, and encumbrances. Use the due diligence checklist in either case.
Step-by-step
- Define required location, right, completion date, and budget.
- Build all-in cost sheets for both candidates.
- Verify title and seller authority.
- For new property, investigate developer and delivery documents.
- For resale, inspect unit, alterations, juristic-person records, and occupancy.
- Compare completed sales and rents, not only asking listings.
- Negotiate conditions, remedies, retention, and document delivery.
- Reinspect before transfer.
Comparison table
| Factor | New development | Resale |
|---|---|---|
| Physical evidence | Limited if incomplete | Actual unit observable |
| Payment | Often staged | Usually compressed around transfer |
| Main counterparty risk | Developer delivery | Seller title and disclosure |
| Building history | Little or none | Accounts and operations available |
| Defects | Construction and specification | Wear, alterations, hidden condition |
Hypothetical example
Assumptions only: New unit price THB 6,200,000 plus THB 400,000 furnishing; resale price THB 5,900,000 plus THB 250,000 repairs. Before transaction costs, totals are THB 6,600,000 and THB 6,150,000. The lower total does not decide quality, title, timing, or resale prospects.
Risks
- Delay, cancellation, substitution, or incomplete infrastructure.
- Resale alteration without adequate approval evidence.
- Underfunded condominium management.
- Promotional furniture masking total cost.
- Paying a premium unsupported by completed comparables.
- Weak contract remedies.
Checklist
- All-in cost compared
- Title and encumbrances checked
- Developer or seller authority verified
- Contract independently reviewed
- Technical inspection completed
- Building accounts and rules reviewed
- Exit demand stress-tested
FAQ
Is off-plan cheaper than resale?
Not necessarily. Compare total cost, delivery risk, time value, specification, and completed evidence.
Is resale safer because it exists?
It removes construction uncertainty but not title, defect, management, tenant, or liquidity risk.
Should the developer's inspector be enough?
No. Use an independent inspector accountable to you.
