Read nominal price, real price, foreign sales and Istanbul separately. A buyer choosing one Residence should not treat the national market as a proxy for title, rent or price evidence.
What changes the buyer's decision?
A rising index can still hide weak foreign demand in a district. A falling foreign-sales total can still leave scarce ready stock in a specific waterfront or branded Residence segment.
Use the official data as a screening layer, then compare the selected Project, Residence and Offer against dated local evidence.
Evidence and checklist
| Buyer moment | Check | Why it matters |
|---|---|---|
| Foreign sales, July 2026 | +1.9% YoY | TUIK programme evidence, accessed 2026-08-24. |
| Foreign sales, Jan-Jul 2026 | -7.3% | Same release; shows year-to-date weakness. |
| Price index | TCMB HPI | Use nominal and real readings separately. |
| Rent context | TCMB YKKE | Rent signal should not replace signed comparable rents. |
| Offer check | Project > Residence > Offer | A market index cannot verify one Residence. |
How to use this in your shortlist
Start with your goal, budget and timing, then test one Project, one Residence and one Offer against the rule above. If evidence is missing, keep the gap visible instead of replacing it with a claim.
