Change Control — Property Valuation Report
Why change control exists
A valuation report is a time-stamped opinion about a defined property interest under stated assumptions. The transaction can change after that opinion was prepared. A different unit may be selected, title identifiers may be corrected, the contract price or payment structure may change, construction may progress, physical works may occur, a new report may be issued, or the official procedure may be updated. Change control prevents the team from continuing to cite the old report automatically. It records the baseline, the new fact, the impact assessment, and the decision on whether the report remains usable.
Freeze the accepted baseline
Record the report reference, report date, inspection date where available, property identifiers, valued interest, purpose, key version marker and the transaction facts against which it was accepted. Preserve that file unchanged. “Latest valuation.pdf” is not a reliable baseline because a later download can overwrite it. The baseline should be reproducible by another reviewer and linked to the decision or payment it supported.
Capture changes as events
A change entry should state what happened, when, who reported it, and the evidence. Examples include a corrected independent-unit number, cadastral renumbering, revised project plan, material renovation after inspection, change from one unit to another, amended buyer structure, revised intended use, or receipt of a later report. Avoid vague entries such as “documents updated.” The reviewer needs to know which fact in the report may no longer match reality.
Classify the impact, not just the change
Not every update requires a new valuation. A spelling correction with no asset ambiguity is different from changing the unit, area, legal interest, physical condition, or transaction purpose. Assess whether the change affects property identity, comparables, assumptions, legal use, market condition, report scope, or procedural acceptance. Record the reasoning. If specialist judgment is required, route the question to the competent valuer or authority rather than inventing an internal validity rule.
Check official-process consequences
For foreign-buyer title procedures, TKGM’s current valuation instructions determine the report requirement and process. Because scope has changed over time, a procedural change can itself reopen the control even if the property is unchanged. Record which official instruction was checked and on what date. The file should distinguish a report that remains useful for commercial analysis from one that is acceptable for a particular official step.
Link to payment and contract controls
If the changed fact affects a condition precedent, payment release gate, financing approval, citizenship file, withdrawal right, or contractual representation, reopen that control. Do not let a “minor update” label bypass a material contractual consequence. Conversely, a non-material administrative correction should not automatically freeze the entire transaction. The purpose of change control is proportional, documented response.
Keep old and new versions
Never replace the prior report in place. Preserve each report and any corrected copy with its own reference, source and receipt date. Document whether the newer report supersedes the old one for all purposes or only for a defined step. If values differ materially, record the explanation or obtain professional clarification. The existence of a newer file is not proof that the former decision was wrong; it is evidence that the basis has changed and should be understood.
Close the change with an explicit decision
Each material change ends with one of several clear outcomes: no impact and baseline remains usable; report remains usable with documented bridge evidence; new or updated valuation required; payment or filing held pending evidence; or risk accepted by an authorized decision-maker for a non-regulatory purpose. State the effective date and affected downstream steps. This prevents teams from using inconsistent report versions in parallel.
Audit test
A reviewer should be able to see the original accepted report, the exact change, supporting evidence, impact analysis, the current TKGM rule if relevant, the decision, and which later actions were reopened. If the only explanation is “we used the newest file,” change control has failed. The objective is not paperwork for its own sake; it is preserving a defensible chain from changed fact to changed—or deliberately unchanged—decision.
