DASK at resale: what will the next buyer need to understand?
A DASK policy that looked routine at acquisition can become relevant again when the property is sold. A later buyer will not be satisfied merely by learning that the owner once had compulsory earthquake insurance. The useful question is whether the current policy belongs to the same dwelling, whether its underlying data can be reconciled, and whether renewals and corrections form a coherent history rather than a collection of unrelated PDFs.
Which evidence retains value at exit?
The most useful continuing record is the policy number, period of cover, address or address code, independent-unit details, floor area used for insurance, construction type and insured amount. Annual renewals should form a readable sequence. If a policy was corrected, retaining the previous version together with the reason for correction is more informative than deleting it and pretending no discrepancy ever existed.
An expired policy is not proof of current cover. It can still prove historical status, for example what policy was in force when the present owner bought the home. At resale, the parties should verify current status through the official channel and use earlier versions only where they genuinely explain the history.
A tariff change is not automatically a property problem
A future buyer may notice that the insured amount is higher than it was in an older policy. That does not automatically indicate a new defect or a change in market value. For policies starting on 1 August 2026, DASK publishes construction unit costs of TRY 11,562/m² for reinforced-concrete buildings and TRY 7,708/m² for other structures, with a maximum insured amount of TRY 2,451,062 per dwelling. A tariff update can change policy figures while the home itself remains unchanged.
The more important issue is an unexplained data difference: a different address, a large change in declared area, a different construction category or a policy that appears to identify another unit. Such inconsistencies can lengthen a later buyer’s due diligence because they concern the identity of the insured risk. Correcting them when discovered, and keeping the explanation, is usually better than leaving the question for the next transaction.
Does the DASK amount determine resale value?
No sound resale analysis treats the DASK insured amount as a valuation. Compulsory earthquake insurance is calculated under insurance rules, whereas a sale price reflects market, legal, physical and commercial factors. The resale value of a well-kept DASK file is informational: it reduces uncertainty by showing that the compulsory policy has consistently been matched to the correct property. It does not establish what the property should sell for.
What should be ready for the next buyer?
Before marketing the home, the seller should be able to produce the current verifiable policy, the property data that explains it, and any earlier version needed to understand a material correction. If renewal is close to the expected transfer date, the file should make clear which policy will actually be valid at transfer. If an address, area or unit mismatch is still open, resolving it before serious negotiations is preferable to allowing the buyer to discover it late in the process.
Keep the scope disciplined
DASK does not prove that a building is structurally safe and does not replace voluntary building or contents insurance. A future buyer may reasonably ask for engineering evidence or broader insurance, but those belong to separate reviews. A clean exit file does not exaggerate DASK; it presents a clear, property-specific insurance history without turning the policy into a technical certificate or market valuation.
Resale-ready conclusion
The strongest preparation is the ability to explain the DASK history quickly: which policy is current, what data ties it to the dwelling, why figures changed when they did, and which version governed each period. That reduces avoidable questions and makes the compulsory-insurance record intelligible to the next owner and to any institution that needs to verify it.
