Core Property Due Diligence Framework™

A six-pillar institutional checklist for evaluating any Thai property project: developer, ownership structure, operator, location, contract economics and exit pathway.

Last reviewed · 2026-06-14

Executive Summary

What Property Due Diligence Framework decides.

The Core Property Due Diligence Framework™ is the standard Core Investments applies before any project is permitted into a client portfolio. It compresses what an institutional acquisition team would test over weeks into a repeatable, comparable six-pillar review. Every pillar must be independently passable; a project that fails any single pillar is rejected regardless of pricing, brand or marketing positioning.

  • 01

    Diligence is the firewall between marketing material and investable inventory.

  • 02

    Six pillars are tested independently: developer, structure, operator, location, contract, exit.

  • 03

    A single failed pillar disqualifies a project — pricing does not compensate for structural risk.

  • 04

    Diligence outputs feed directly into the Net Yield Underwriting Method and the Total Return Component Model.

  • 05

    The framework is the same across Phuket, Bangkok, Pattaya and submarket-level acquisitions.

When To Use

Apply this framework when…

  • ▸Any off-plan or completed project under live consideration.
  • ▸Comparing two or more shortlisted projects on a like-for-like basis.
  • ▸Validating a project before committing the reservation deposit or contract execution.
  • ▸Reviewing an existing portfolio holding ahead of a renewal, refinancing or resale decision.

When Not To Use

Do not apply when…

  • ▸Lifestyle-only acquisitions without investment-return objectives.
  • ▸Pre-construction land plays where no project structure yet exists (use land-banking methodology instead).

The Framework

Core Property Due Diligence Framework™

Proprietary Core Investments methodology. Designed for repeatable, comparable, evidence-based investment decisions.

  1. 01

    1. Developer

    Track record across delivered projects, financial standing, completion ratio, after-sales performance and any disputes or regulatory actions of record.
  2. 02

    2. Ownership Structure

    Freehold quota, leasehold tenure, Thai company or BVI route mapped to the buyer's nationality and tax position under the Core Foreign Ownership Framework.
  3. 03

    3. Operator (if hotel-managed)

    Operator credibility, contract economics, realised RevPAR, sinking-fund position and brand-standard exposure — escalated to the Core Hotel-Managed Diligence Framework.
  4. 04

    4. Location & Submarket

    Submarket selection, beach access, transit anchor or infrastructure catalyst, demand profile and competing pipeline within 1 km.
  5. 05

    5. Contract Economics

    Payment plan, transfer terms, guaranteed returns, FF&E reserve, marketing levy, owner-use blocks, termination rights and dispute resolution.
  6. 06

    6. Exit Pathway

    Secondary-market depth, lease assignability, foreign-buyer pool, comparable resale evidence and structural exit constraints — escalated to the Core Exit Strategy Framework.

Inputs

Variables in.

  • · Developer delivery history
  • · Foreign ownership structure and quota position
  • · Operator contract and 24–36 months realised P&L (if hotel-managed)
  • · Submarket pricing comparables
  • · Full contract and addenda
  • · Secondary-market liquidity data

Outputs

Decisions out.

  • · Pillar-level pass / fail rating
  • · Aggregate diligence verdict
  • · Diligenced net-yield input
  • · Identified material risks
  • · Pre-contract negotiation list
  • · Recommended structuring approach

Worked Example

Property Due Diligence Framework, applied to a Thailand case.

A Bang Tao branded condominium offered at THB 18m. Developer is a Tier-1 Thai listed group (pass). Foreign freehold quota verified at 41% (pass). Operator is a global flag on a 60/40 owner-favourable contract (escalated to Hotel-Managed Diligence — pass). Location is 400 m to Bang Tao beach with no competing pipeline within 1 km (pass).

Contract review identifies a 4% FF&E reserve and 2% marketing levy not in the brochure, and a 5-year owner-use restriction (conditional — renegotiate). Exit pathway shows shallow secondary-market depth for hotel-managed product at this price point (conditional — escalate to Exit Strategy Framework).

Framework output: investable subject to renegotiation of contract terms and an explicit pre-purchase exit plan. Diligenced net yield drops from 8% brochure to 4.9% — which becomes the underwriting input.

Common Pitfalls

Where investors get this wrong.

  • !

    Trusting brochure economics rather than independently testing each pillar.

  • !

    Treating a strong developer or famous operator as a substitute for contract diligence.

  • !

    Skipping submarket pipeline analysis and discovering competing supply post-purchase.

  • !

    Ignoring exit pathway because the holding period feels distant.

  • !

    Allowing one strong pillar to override a weak one — they must all pass.
