Land-use classification Verification Guide
effective use plan scale plan notes parcel mapping later changes Cross-check For the verification guide focus, test the strongest claim first. If plan notes conflicts with parcel mapping, preserve both pieces of evidence and identify the reason for the conflict before treating the file as complete. Mismatch resolution A common failure pattern is that effective use appears correct while later changes is missing, stale or linked to another record.

Buyer Questions for Land-use classification
Ask the exact plan designation, permitted functions, whether housing/commercial use is principal or conditional, maximum development parameters where relevant, special-plan notes, protection status and whether a plan amendment is pending. land-use classification: A marketing description of land does not by itself determine building or use rights; cadastral identity must be separated from the planning/land-use rules currently applicable to the parcel.

Closing-Day Check for Land-use classification
Before closing, reconfirm the designation and any posted plan change. If purchase value depends on a particular future use, document that assumption separately and do not present it as an existing legal entitlement. land-use classification: A marketing description of land does not by itself determine building or use… Its purpose is to turn information into a traceable decision: what must be checked, which document or register proves the result, when the check must be repeated, and how any conflict affects purchase, sale, leasing or handover.

Earthquake Risk, Structural Inspection and Building-Age Due Diligence
“Earthquake Risk, Structural Inspection and Building-Age Due Diligence” engages Condominium Ownership Law No. 634 whenever the issue concerns an independent unit, common part, land share or site management. The law distinguishes independent sections, common areas and appurtenances and regulates management, common expenses and advances. An aidat amount, parking/storage right or ownership-share ratio should therefore not be accepted from a seller’s statement alone; the management plan, decision book, unit ledger, registry and approved project are checked according to the issue.
Read topic →Building age and renovation history Verification Guide
A Turkish property guide to verifying building age and renovation history: separate permit and occupancy dates from finish age, document later alterations, repairs and strengthening, and never treat cosmetic renovation as proof that the structure is newer or safer.
Read topic →Buyer Questions for Building age and renovation history
Buyer questions should be evidence-producing, not conversational. In “Buyer Questions for Building age and renovation history”, apply this evidence through the buyer-question review and reconcile building/renovation/buyer/questions to the controlling record for the same property before accepting the conclusion. For “Buyer Questions for Building age and renovation history”, compare documentary status with the physical, payment or operational reality relevant to the topic and write down every unexplained difference before commitment.
Read topic →Closing-Day Check for Building age and renovation history
Closing-day control re-checks items that can change up to the last moment: attendee/agent identity, final contract version, registry status, beneficiary account, amount, keys and handover. Do not assume last week’s check is automatically still valid. For “Closing-Day Check for Building age and renovation history” specifically, apply that point through the closing-day check and tie the conclusion to the same property, party and decision date rather than carrying it over from another transaction.
Read topic →Building age and renovation history Red Flags Guide
original permit occupancy date major alterations reinforcement later approvals How to test the red flags For the red flags, test the strongest claim first. If major alterations conflicts with reinforcement, preserve both pieces of evidence and identify the reason for the conflict before treating the file as complete. Stop conditions A common failure pattern is that original permit appears correct while later approvals is missing, stale or linked to another record.
Read topic →Structural Inspection and Risky-Building Verification Guide
A structural-inspection guide for buying property in Türkiye: verify the exact building and inspection scope, distinguish visual screening from performance assessment or formal risky-building determination, and require proportionate engineering evidence and testing where needed.
Read topic →Buyer Questions for Structural inspection
Failure example: structural looks correct, but official belongs to a different date, unit or transaction. AFAD ties seismic design to code requirements, ground conditions and engineering services, so distinguish preliminary screening from a decision-grade report. A rapid structural screening is not a detailed seismic-performance report. The building earthquake code sets minimum design conditions considering hazard and ground characteristics; assessing an existing building therefore requires building, structural-system and ground evidence, not the map colour alone.
Read topic →Closing-Day Check for Structural inspection
Separate seller assertion from official record. For “Closing-Day Check for Structural inspection”, begin with structural and inspection and make sure both relate to the same asset, party and review date. Mark each as verified, conflicting, stale or unavailable. Check closing independently from the person or document that supplied structural. If it conflicts with official, identify the authoritative owner of the fact and obtain a fresh record.
Read topic →Structural inspection Red Flags Guide
