Key takeaways
- The difference between a Pre-Feasibility Model and an Investment-Grade Model lies in the quality and source of the data, not the complexity of the formulas.
- This article organises the data into 10 categories for a luxury mixed-use project, together with their order of priority.
- All figures are illustrative examples and reference ranges drawn from the author's experience. They must be confirmed against the actual documents of each project.
Why you need a data map
In a mixed-use project combining a 5-star hotel, a wellness centre, fine-dining restaurants and Branded Residences, the difference between a Pre-Feasibility Model and a model submitted to financial institutions, institutional investors and the BOI lies not in the complexity of the formulas, but in the quality and source of the data fed into it.
The most common problem is not a lack of modelling skill but the lack of a data map from the outset. Teams end up revising assumptions repeatedly as actual data trickles in, and when they submit the model to a bank or an investor, they cannot cite the sources behind their figures.
The sample project used
For illustration, assume a sample project on the west coast of Phuket: about 45 rai of beachfront land, a total investment of roughly THB 8,500–10,000 million, and a 36-month construction period, comprising 4 business units.
| Business unit | Details |
|---|---|
| BU1 Hotel | 5-star hotel with 180 rooms, managed by an international hotel chain |
| BU2 Wellness & Medical Spa | About 3,500 sq m, including Medical Wellness, Day Spa, and Fitness & Longevity |
| BU3 Signature Restaurants | 4 concepts with 480 seats in total, serving both hotel guests and outside customers |
| BU4 Branded Residences | 60 units (30 pool villas and 30 Sky Residences units) |
Initial assumptions: Year 3 ADR averages THB 18,000, occupancy 68%, and the Branded Residences price averages THB 95,000 per sq m. For ownership of condominium units, foreign buyers may hold under the 49% quota of the total unit area. For leasehold structures, the term and renewal rights must be checked against the latest law and a lawyer's opinion obtained.
Category 1: Investment budget and construction costs
A capex error of just 5–10% can reverse an investment decision, especially in luxury projects where cost per key can reach THB 25–45 million per room.
Land acquisition
| Data required | Source |
|---|---|
| Title deed with GPS coordinates | Land Department |
| Official appraised value | Treasury Department |
| Comparable market prices | Independent appraiser |
| Soil survey results | Registered soil survey firm |
| EIA report | Office of Natural Resources and Environmental Policy and Planning (ONEP) and registered report preparers |
| Zoning and town planning | Local municipality or Subdistrict Administrative Organisation |
| Land use rights (freehold/leasehold) | Real estate lawyer |
Where the land is beachfront and partly within a conservation area, the EIA is a precondition for the building permit. If the main investor is a foreign party, holding the land through a Thai company requires Thai shareholders who genuinely invest, not nominees, and a written legal opinion should be obtained to support due diligence.
Hard Cost
Reference ranges for Phuket: hotel portion THB 75,000–110,000 per sq m, and top-tier pool villas or Sky Residences THB 95,000–140,000 per sq m.
| Data | Source |
|---|---|
| EPC quotations from at least 3 firms | Main contractor |
| BOQ separating materials and labour | Quantity Surveyor |
| Schematic Design and Detailed Design | Architecture firm |
| MEP design and costs | MEP engineering consultant |
| Structural Engineering | Structural consultant |
| Cost per Sqm Benchmark | International cost consultant |
| Construction Schedule | Project manager or contractor |
| Escalation Rate | Ministry of Commerce and the construction materials price index |
Compare at least 3 EPC quotations against the benchmark. If the gap is no more than 8%, the market reflects real prices; if it exceeds 15%, go back and check the scope of work immediately.
Soft Cost
Typically 12–18% of hard cost for a luxury project, comprising architect fees of 5–8%, project management of 3–5%, permit fees, legal fees, construction insurance (CAR/EAR at about 0.3–0.5% of hard cost) and a loan arrangement fee of 0.5–1.5% of the facility.
FF&E and OS&E
For a 5-star hotel, FF&E is about THB 1.8–2.8 million per room and OS&E about THB 250,000–400,000 per room. This item must be approved by the operator and is usually designed by an international interior designer.
Category 2: Personnel
Personnel costs in a luxury hotel are around 28–35% of total revenue, higher than the industry average of 22–26%, because the staff-to-key ratio of a luxury 5-star hotel is 1.6–2.2 staff per room. The 180-room sample project therefore has about 320–380 staff, excluding about 45 in wellness and about 95 in restaurants.
Headcount Plan
Compile departmental org charts, job descriptions, reporting lines and, most importantly, a monthly headcount ramp-up schedule for the 12 months before opening.
Correcting a common misunderstanding Pre-opening expenses must be included in the model's investment budget (funding budget) so that there is enough money, but in the financial statements, pre-opening costs and staff training are not included in the cost of buildings and equipment under TAS 16; they are recognised as expenses when incurred. The model must therefore separate the funds to be raised from the accounting recognition.
Compensation Benchmarks
| Position | THB/month | Sources |
|---|---|---|
| General Manager (Expat) | 350,000–600,000 | International remuneration survey |
| Director of F&B | 180,000–280,000 | Hotel industry survey |
| Executive Chef | 200,000–350,000 | Food and beverage recruitment firm |
| Spa Director | 120,000–180,000 | Wellness industry survey |
| Front Office Manager | 80,000–130,000 | Hotel industry survey |
| Room Attendant (Local) | 13,000–17,000 | Local wage survey |
Benefits and statutory obligations
Includes employer social security contributions (check the latest rate and wage ceiling under the ministerial regulation as at the model date), provident fund of 5–15% on a matching basis, group health insurance of THB 3,500–8,000 per person per year, a service charge pool (typically 8–10% of revenue on which service charge is collected), staff meals at THB 90–130 per meal, overtime, severance pay under labour law, and performance bonuses.
Training
Pre-opening training for a luxury hotel is about THB 35,000–55,000 per person; ongoing training is 1.5–2.5% of payroll per year; and visa and work permit costs for senior foreign staff are about THB 35,000–60,000 per person per year.
Category 3: Revenue and operating assumptions
Revenue comes from five streams: rooms, food and beverage, spa and wellness, signature restaurants, and Branded Residences, from both sales and rental pool share.
Hotel Revenue Drivers
Start with a market report to define a compset of 5–10 comparable hotels, then use it as the basis for project ADR and occupancy over 5–10 years. Consider channel mix, seasonality, length of stay and source markets.
| Revenue driver | Year 3 assumption | Reference data source |
|---|---|---|
| Average ADR | THB 18,000/night | STR Compset Analysis |
| Occupancy | 68% | Local hotel market report |
| RevPAR | THB 12,240/night | ADR × Occupancy |
| Average Length of Stay | 3.8 nights | Tourism statistics |
| Channel Mix: Direct | 32% | Operator Plan |
| Channel Mix: OTA | 28% | Operator Plan |
| Channel Mix: Wholesale/TO | 25% | Operator Plan |
| Channel Mix: Corporate/MICE | 15% | Operator Plan |
F&B and restaurants
The capture rate of hotel guests is typically 65–80% for breakfast (often included in the package), 35–50% for lunch and 40–55% for dinner. Banquet and wedding revenue averages 12–18% of total F&B revenue in Phuket.
Wellness and spa
Average revenue per treatment is THB 4,500–7,500 for the day spa and THB 18,000–60,000 per programme for medical wellness programmes. Use Global Wellness Institute reports as a reference for market growth, and check the latest figures before use.
Branded Residences
This is the fastest cash inflow in a mixed-use project because sales can open ahead of completion. Use independent market reports to set the brand premium against non-branded projects, with a reference range of about 25–45%. In the sample project, the average price is set at THB 95,000 per sq m for pool villas, with an expected net rental yield of 5–7% from the rental pool, which must be tested to confirm it is the real return after all expenses.
| Data to collect | Source |
|---|---|
| Branded Residences Report | International real estate consultant |
| Comparable luxury sales in the area | Local real estate agents |
| Rental Pool Performance Benchmark | Real estate consultant and hotel operator |
| Sales Take-Up Curve | Project marketing plan |
| Investor Profile | Developer's historical sales data |
| Service charge and CAM fees | Property Management Benchmark |
Category 4: Operating costs
Refer to the latest USALI standard (12th Revised Edition, effective from January 2026) so that figures can be compared correctly against industry benchmarks.
| COGS | % of departmental revenue |
|---|---|
| Food Cost | 30–34% |
| Beverage Cost | 22–28% |
| Spa Product Cost | 8–12% |
| Retail Cost of Goods | 45–55% |
Rooms department expense, including payroll, linen, cleaning supplies and guest amenities, is about 22–28% of room revenue; F&B department expense is about 70–82% of F&B revenue; and spa department expense is about 55–68% of spa revenue.
| Undistributed Operating Expenses | % of total revenue |
|---|---|
| A&G | 6–9% |
| IT & Telecom | 1.2–1.8% |
| Sales & Marketing | 5–8% |
| POMEC | 7–10% |
For energy, the benchmark is 180–280 kWh/m²/year. Fixed charges comprise land and building tax (check the rates by type of use and the measures in force for the tax year of the model), property and business interruption insurance of about 0.18–0.28% of replacement cost per year, annual licence fees, and land rent in the case of leasehold.
Category 5: Sales and marketing
Split into pre-opening marketing and annual operating marketing. The pre-opening budget is recommended at 2.5–4.0% of Total Project Cost, or roughly THB 225–360 million on a THB 9,000 million project base. It covers brand launch, PR, photography, trade shows and digital assets. The model includes it in the funding requirement, but in the accounts it is expensed as incurred, like other pre-opening items.
Distribution cost must cover OTA commission of roughly 15–22%, channel manager subscription, GDS fees, the operator's CRS, the hotel group's loyalty programme costs, and travel agent commission of 8–12%.
Category 6: Management agreement and brand
The Hotel Management Agreement has the greatest impact on cash flow over 25–30 years, because it sets every tier of fees, the marketing contribution and the performance test.
| Item | Market range | Notes |
|---|---|---|
| Base Management Fee | 1.5–3.0% of Total Revenue | Luxury is typically 2.5–3.0% |
| Incentive Fee | 6–10% of GOP | An owner hurdle applies before the split |
| Group Services Fee | 1.0–2.5% of Room Revenue | CRS, Loyalty, Brand Marketing |
| Technical Services Fee | USD 1.2–2.5 million | Paid in the pre-opening period |
| FF&E Reserve | 3–5% of Total Revenue | Starts at 2% in year 1, then increases gradually |
| Marketing Contribution | 1.5–2.5% of Room Revenue | In addition to the Sales & Marketing budget |
The owner should negotiate a two-test failure performance test (both the GOP threshold and the RevPAR Index falling below 90% of the comp set) to preserve the right to replace the operator.
Category 7: Capital structure
For a mixed-use project of about THB 9,000 million, a suitable structure is 35–45% equity and 55–65% debt, with a 36-month construction loan converting into a 12–15-year term loan on opening. Presale proceeds from branded residences may reduce Peak Funding by 15–25%.
Debt
Obtain bank term sheets from at least 3 commercial banks to compare interest rate, LTV/LTC, tenor, amortisation, DSCR Covenant (generally not below 1.30x), 6-month DSRA, prepayment penalty and conditions for conversion to a term loan.
Equity
The documents comprise the shareholder agreement, equity drawdown schedule, investor hurdle rate, promote structure (for example, a 20% carry after investors achieve a 10% IRR) and reserved matters.
Alternative funding sources
Mezzanine debt at 12–16%, convertible notes for institutional investors, and Presale funds, for which escrow arrangements and transfer conditions must be tightly structured before they are counted as a funding source.
Category 8: Tax and legal
Consider applying for BOI promotion for the hotel business, checking the activity type, conditions and privileges under the latest BOI announcement. Plan for VAT refunds during construction, withholding tax (WHT) on management fees paid to a foreign operator under each country's double taxation agreement, and transfer pricing documentation for intragroup transactions.
| Licence | Authority |
|---|---|
| Hotel business licence (Hotel Act 2004) | Department of Provincial Administration or the agency to which the function is delegated by law |
| Liquor licence | Excise Department |
| Restaurant public health licence | Local government |
| Health establishment licence | Department of Health Service Support |
| Medical spa or healthcare facility licence | Department of Health Service Support |
| Building permit | Local government |
| EIA report | Office of Natural Resources and Environmental Policy and Planning (ONEP) |
| Foreign business licence (if applicable) | Department of Business Development (DBD) |
Category 9: Technical and engineering
Institutional investors are giving ESG more weight, so technical information must be included in the Investment Memorandum: energy modelling (kWh/sq m), water use modelling, the LEED, EDGE or EarthCheck certification plan, solar PV study results, HVAC sizing and operating costs, and the backup power system.
The information systems to be specified in CAPEX are PMS, POS, channel manager, spa booking, F&B inventory, Wi-Fi infrastructure, CCTV and access control, including smart room technology, totalling about 4–7% of the FF&E budget.
The maintenance plan should set an annual CAPEX reserve starting at 1% of revenue in the first year and rising to 4–5% from year 5. Plan major refurbishment cycles every 6–8 years for soft goods and every 12–15 years for hard goods.
Category 10: Market intelligence and risk
The first document institutional investors ask for is a Feasibility Study by an independent hospitality consultant, costing roughly THB 2–4 million per project. It covers market demand, competitor pipeline, tourism forecast, air connectivity and cruise tourism.
- Political Risk Political risk insurance
- Climate Risk Sea level and storms
- Pandemic Sensitivity Simulate occupancy falling by 40–60% for 12–18 months
- Currency Risk USD/THB policy when most revenue comes from foreign tourists
- Earthquake/Tsunami Zone Assessment
- ESG Reporting framework (GRI or SASB), carbon footprint baseline, community impact plan and local hiring target, for which the industry benchmarks used as reference typically set 80–85%

This table is the budget for the set of work needed to bring the model to investment grade. It is not the project's total soft cost, which must be calculated from actual hard cost at 12–18% as set out in Category 1.
Conclusion
A model built on assumptions suits preliminary studies, introductory investor presentations and internal go/no-go decisions. To upgrade it for bank funding (requires a bank term sheet and a verifiable DCF), equity fundraising (requires a Feasibility Study and an HMA term sheet) or BOI promotion (requires detailed CAPEX and an employment plan), data must be gathered systematically under this framework.
The key is not the complexity of the model but the quality of the input data and the ability to trace the source of every figure, so that it passes due diligence by every party, from the bank's credit department and the BOI committee to the auditors.
Model structure and build discipline
Once the data is ready, the model should have clearly separated functions: Cover, Assumptions, Sales Schedule, Construction S-Curve, OPEX, Debt, Tax, 3-Statements, Returns and Dashboard.
| FAST principles | Meaning |
|---|---|
| Flexible | Assumptions are separate from calculations. Change an input and the outputs update automatically, with support for scenarios |
| Appropriate | Complexity matches the users and the decision |
| Structured | Consistent layout, with flow from input to calculation to output |
| Transparent | Easy to read and trace back, with clear error checks |
Model Audit Checklist
- No hard-coding in formulas, and every input in one place only
- Assets equal liabilities plus equity in every period
- Closing cash on the balance sheet matches the cash flow statement
- Scenario toggle works and error checks are zero everywhere
- No unnecessary circular references, especially in the interest calculation
- Record the version and change log, e.g. Project_Model_v1.0_YYYYMMDD
- Passes a 3-level review: self-review, peer review and independent review
