New-build versus resale property in Türkiye: compare evidence, not age
Choosing between a new-build and a resale property is not a simple choice between “modern” and “old”. The two categories concentrate risk in different places. A new development may offer staged payments, current specifications and unused interiors, but the buyer can be exposed to construction, delivery, developer and final-permit risk. A resale home can be inspected in its actual condition and may have a visible operating history, yet it can contain deferred maintenance, unapproved alterations, tenant issues or old building systems. A useful comparison therefore applies the same legal, physical and financial questions to both while adding checks specific to each category.
For new-build, start with the project and seller’s authority
Verify the land parcel and registered owner through TKGM, identify the legal seller and contractor, and review the Yapı Ruhsatı and approved architectural project. The apartment marketed to the buyer should be traceable by block, floor and independent-unit identity. If the project is still under kat irtifakı, understand what is registered today and what documentation is expected at completion. Sales brochures, model units and project brands do not replace the approved project or the legal basis allowing the seller to dispose of the selected unit.
For resale, start with the current registered and physical property
Obtain a current title/registry review showing the owner and relevant mortgages, attachments, annotations and other restrictions. Then compare the physical apartment with the approved project and title identity. Check occupancy/use documentation, current condominium status and any later alterations. A resale unit gives the buyer the advantage of inspecting what actually exists, but this advantage is lost if the inspection is not reconciled with official documents.
Compare condition and defect risk differently
New-build buyers should conduct a detailed snagging and handover inspection, test installed systems and compare finishes with the signed specification. The absence of wear does not mean the unit is defect-free; water ingress, incomplete sealing, poor installation or unfinished common areas can emerge only at delivery. Resale buyers should focus on age and maintenance history of roof, façade, lifts, plumbing, heating/cooling and electrical systems, plus evidence of damp, cracking or repeated repairs. Major common works can create owner costs immediately after purchase.
Compare permissions and condominium status
For a completed new project, check Yapı Kullanma İzin Belgesi and the expected transition to kat mülkiyeti. For resale, verify that the status shown in the registry still corresponds to the completed building and the unit’s current use. An old occupancy permit does not legalise later unapproved changes; a new project’s building permit does not prove that final occupancy has already been obtained. Each document should be used only for the fact it proves.
Calculate total acquisition and holding cost
Do not compare only headline purchase prices. New-build property may require fit-out, furniture, utility activation, interim construction-period payments and a waiting period before rental income begins. Resale may require renovation, appliance replacement or immediate common-area assessments. In both cases include title fees, applicable taxes, professional services, DASK and other insurance, aidat, management and financing. A unit that is cheaper at contract can be more expensive over the first two years.
Evaluate income and resale liquidity on the same basis
For investment, estimate achievable rent from current comparable units rather than the developer’s forecast or the seller’s old lease alone. TCMB’s housing-price and new-tenant-rent indices provide market context but do not value a specific apartment. Consider vacancy, owner-paid aidat and competition from similar stock. In a large new project, many identical units may reach the rental or resale market at once. In an older building, unusual layout, weak documents or expensive upcoming repairs can narrow the buyer pool.
Match the category to the buyer’s risk capacity
A new-build may suit a buyer who can tolerate delivery timing and project execution risk in exchange for modern systems or staged payment. A resale property may suit a buyer who values immediate possession and observable performance but can manage renovation and legacy-document issues. Neither category is inherently safer or more profitable. The correct decision is the property whose registered identity, permits, physical condition, total cost, realistic income and exit market remain acceptable after the same conservative due-diligence process.
