Prevent omissions
Keep required checks in a visible sequence instead of relying on memory.
This checklist turns the verification steps from 01–06 into a document you can follow during a real transaction. ESSENTIAL covers the core checks that can change whether the deal should proceed, while DETAIL adds transaction-specific variables that require closer review.
People, documents, money, and deadlines move at the same time during a transaction. Even previously verified items can be missed, and memory can be confused with actual evidence. This checklist is therefore not a summary of knowledge; it is a control tool that keeps required verification actions visible.

Keep required checks in a visible sequence instead of relying on memory.
Do not move directly to signing, payment, or closing while an essential item remains unverified.
Facts that were correct at signing can change before closing, so key items must be checked again.
ESSENTIAL is not a list of merely common items. It focuses on issues that can undermine the transaction itself, directly affect payment, release of rights, title transfer or handover, or create losses that are difficult to recover. It is the minimum set of checks needed to decide whether the transaction should continue.
DETAIL is the expanded version and includes all 18 ESSENTIAL checks. Because the core list alone cannot cover every transaction-specific issue—such as co-ownership, agency, tenants, security rights, financing, facilities, vacancy, record-to-site mismatches, or post-signing changes—it adds detailed cross-checks across records, the site, the contract, leases, facilities, and settlement data.
Use ESSENTIAL when you need a fast screen at the start of a deal, a core check before signing, or a quick recheck just before closing.
Use DETAIL when preparing an actual contract or when the transaction has many variables such as tenants, co-owners, agents, security rights, facilities, or financing.
Recommended: screen with ESSENTIAL first, then use DETAIL to investigate incomplete or unclear items. If you want a full review from the start, you may begin directly with DETAIL.
Use ESSENTIAL to check the 18 core items that can change whether the deal should proceed.
Use the matching WHO / WHAT / MONEY / TERMS / RECHECK / CLOSE section in DETAIL for deeper verification.
Recheck MONEY and TERMS in DETAIL and fix payment, release, repair, vacancy, and facility agreements in writing.
Use RECHECK to compare the signing baseline with the current condition.
Review the ESSENTIAL core items together with CLOSE in DETAIL to make one final check of money, rights, documents, and handover.
The two documents are not competing lists; they are a compact version and an expanded version. ESSENTIAL is for fast core decisions, while DETAIL includes all 18 ESSENTIAL checks for a precise review. Do not mark an unverified item as complete.

18 core checks for deciding whether the transaction should proceed.
