Most foreign buyers verify nothing. They trust the listing, wire the money, and learn what they skipped after the transfer. The checks below are what I run before a single baht moves.
// Who checks what
Verifies the purchase is legal. Title transfer, contracts, registration. Essential — keep one.
Verifies the building is sound. Structure, systems, snag list.
Runs the transaction. Viewings, negotiation, paperwork flow.
Verifies the deal itself. Whether your name can legally go on the title. What the unit really rents for. The complete fee stack. Who buys it from you in five years, and at what number.
That's the check I run.
// The checklist
Title type + foreign quota headroom. Whether your name can legally go on the title — and how much of the building's 49% foreign quota is actually left. Quota slots move; most buyers never ask.
Real rental comps. What identical units in the same building actually rent for, cross-checked across portals — not the projection on the listing.
The complete fee stack. Transfer fee, sinking fund, CAM, land & building tax. The recurring costs that never appear on a listing page.
Building financials. Whether the building collects enough to maintain itself — or whether a special assessment is waiting for the next owner.
Off-plan delivery record. Buying off-plan? The developer's completed projects and delivery history — verified, not the renders.
Resale liquidity. How many units like yours actually changed hands in that district — and how long they sat before they did.
The exit math. Who buys it from you in five years, at what realistic number, after every cost. The question the brochure never answers.
Name and email. I send the sample report pages + the full property checklist.

The checklist shows you what to check. The Thailand Underwriting Protocol is the whole system — the 5-step framework I ran across 37,750 listings, so you can run every check yourself. $20, instant PDF — and it's credited against the $499 report if you upgrade within 30 days.

A real section from a delivered Chiang Mai report. District medians from a live scan of 4,075 listings. The verdict columns and building names are what clients pay for — those stay withheld.
| # | Area | Median ฿/m² | Rent ฿/m²/mo | The math | Verdict |
|---|---|---|---|---|---|
| 1 | Tha Sala | ฿24,900 | ฿183 | ████ | ██████ |
| 2 | San Sai | ฿30,750 | ฿190 | ████ | ██████ |

| 5 | Nimmanhaemin | ฿63,450 | ฿319 | ████ | ██████ |
Five of eleven districts shown. Full ranked table, building shortlist and unit verdicts ship in the report.
The first client commissioned Bangkok — then came back for Phuket the same week. Nobody orders a second report unless the first one paid for itself.
// What verification costs
| Full legal due diligence (Thai law firm) | $860–$2,900 |
| Pre-purchase building inspection | $499 |
| Contract review alone | $430–$860 |
| The Custom Investment Report — your full shortlist underwritten, verdicts included, 5-day delivery | $499 |
Each does a different job. None replaces the other. Market rates from published Thai law-firm and inspection pricing, mid-2026.
// The findings floor
If your report doesn't surface at least 5 verifiable, material facts about your shortlist you didn't already have — quota status, real rent comps, the complete fee stack, resale liquidity — full refund. Read it first. Then decide it was worth it.

// Straight answers
No. This is independent market research. It works alongside your lawyer, not instead of one — your lawyer verifies the purchase is legal; the report verifies the deal itself.
Any Thai city with enough live listing data to underwrite — Bangkok, Chiang Mai, Phuket, Pattaya, Hua Hin and most provincial capitals. Bali, Vietnam and Philippines reports are also available.
Then the report says don't buy — unit by unit, with the reasons. A pass verdict on a weak shortlist is worth more than any purchase. You also see what a stronger shortlist looks like in the same market.
5 days from commissioning. Capacity is 2 reports per week — the 24-hour brief reply tells you the next open slot.
Your target city, budget, and — if you have one — the shortlist. No shortlist yet? The report builds one from 37,750 filtered listings instead.
