Direct answer
The purchase price is only the starting point. A sound condominium budget includes due diligence, transfer allocations, finance, fit-out, common-area fees, sinking-fund contributions, insurance, utilities, repairs, tax, management, vacancy, currency effects, and eventual sale costs. Use building documents and written quotations instead of generic percentages.
Key takeaways
- 1.Separate one-time acquisition, recurring ownership, rental-operation, and exit costs.
- 2.Read juristic-person financial statements, budgets, arrears, insurance, and planned capital works.
- 3.Contract wording determines who pays many transfer-day items; verify it before reserving.
- 4.Model vacancy, repairs, currency movement, and resale friction rather than treating rent as profit.
Important terms
Common-area fee — Regular contribution to operate and maintain shared property.
Sinking fund — Money reserved for major future works. A healthy balance does not eliminate the possibility of a special assessment.
Special assessment — An additional owner contribution approved or demanded for costs outside the ordinary budget.
All-in cost basis — Purchase price plus buyer-paid acquisition, improvement, finance, and directly attributable costs.
Detailed answer
Organise the budget into four ledgers.
Acquisition: reservation, legal review, technical inspection, valuation, transfer allocations, mortgage costs, initial common charges, sinking fund, furniture, appliances, and repairs.
Recurring ownership: common fees, insurance not carried by the building, utilities, maintenance, tax where applicable, bank charges, and periodic replacement.
Rental operation: agent commission, management, cleaning, platform costs, utilities paid by owner, vacancy, tenant damage, compliance, and income-tax advice.
Exit: agency, legal work, discharge of finance, tax and transfer allocations, refurbishment, vacancy during marketing, and currency conversion.
The seller's brochure cannot establish these figures. Request the condominium juristic person's current budget, audited accounts where available, owner-payment records, insurance summary, meeting minutes, major-work plan, and written confirmation of charges affecting the unit. Pair this guide with who pays closing costs.
Step-by-step
- Record the negotiated price and payment currency.
- Obtain written transfer-day estimates from independent counsel.
- Review juristic-person accounts, budget, arrears, disputes, insurance, and planned works.
- Price furnishing and immediate defects with written quotations.
- Build annual low, base, and high operating budgets.
- If renting, model vacancy and management before tax.
- Add an exit scenario and currency sensitivity.
- Keep a reserve separate from the purchase funds.
Comparison table
| Cost group | Evidence to request | Common budgeting error |
|---|---|---|
| Acquisition | Contract and written completion statement | Counting only purchase price |
| Building | Budget, minutes, accounts, fee letter | Ignoring special works |
| Unit | Inspection and repair quotations | Assuming new means defect-free |
| Rental | Management proposal and actual comparable leases | Using advertised rent |
| Exit | Adviser estimate and realistic selling period | Treating asking price as proceeds |
Hypothetical example
Assumptions only: Purchase price THB 5,000,000; buyer-paid acquisition and legal costs THB 150,000; furnishing THB 250,000; first-year common, insurance, utilities, and repairs THB 90,000.
The first-year cash commitment is THB 5,490,000 before finance, rental tax, vacancy, or resale costs. These numbers are invented solely to demonstrate method. They are not statutory rates or market averages.
Risks
- Underfunded building maintenance or high owner arrears.
- Special assessments after transfer.
- Water, façade, lift, fire-system, or mechanical defects.
- Rental restrictions or weak actual demand.
- Tax treatment assumed from the seller's circumstances.
- Foreign-exchange losses changing the home-currency result.
Checklist
- Contract and transfer allocation reviewed
- Juristic-person accounts, minutes, arrears, and insurance checked
- Unit inspected and repairs priced
- Three-year operating budget prepared
- Rental and vacancy assumptions evidenced
- Exit costs and currency risk included
- Contingency reserve retained
FAQ
Are common fees the only recurring building cost?
No. Insurance gaps, repairs, replacement, utilities, tax, and special assessments may also matter.
Does a sinking fund guarantee no future assessment?
No. Compare its balance and collection record with planned capital works.
Can the seller tell me the exact transfer costs?
The seller can propose an allocation, but obtain an independent calculation using current facts and official requirements.
Where should I start on taxes?
Read Thai property transfer fees and taxes and land and building tax, then obtain tailored advice.
