ERFAN –NAJI

Judgment should be visible.

Six claims buyers hear about Istanbul, and what the documents actually say: the price index, the citizenship rules, the rent law, the building code.

The market TCMB Konut Fiyat Endeksi

Istanbul housing lost ground after inflation, and gained in dollars, over the same two years.

Twenty-four months to July 2026

+70.6%In lira
−3.0%After Turkish inflation
+19.2%In US dollars

Turkish consumer prices rose faster still, so the real reading is negative; the lira slid more slowly than house prices climbed, so the dollar reading is positive. Both stand at once. Which one matters depends on the currency you keep.

Residency & regulation The citizenship threshold

Shaving the deed price to save the fee can cost the citizenship.

The threshold, tested twice over

$400,000On the deed
$400,000In payments transferred

The purchase money is converted through a Turkish bank, and the lira figure on that certificate is what gets declared as the sale price. Since 19 December 2025 the base is floored at the property-tax value; a price found to be non-genuine is reassessed with a penalty equal to the tax. If the shaved figure falls under $400,000, it breaks the citizenship application.

The deed price is not a dial you turn down. What you send through the bank is what lands on the deed.

The market Türk Borçlar Kanunu md. 344

There has been no 25% cap on residential rent since 1 July 2024.

August 2026 CPI, released 3 September

31.79%The ceiling on this reading
31.51%The headline quoted in its place

What governs a renewal now is the standing rule the cap had suspended: the increase may not exceed the twelve-month average change in consumer prices. It binds the rent agreed for a renewed lease and nothing else. The ceiling is the twelve-month average, not the headline annual rate that gets quoted in its place.

Residency & regulation Katma Değer Vergisi Kanunu md. 13/i

The VAT exemption claws back for three years, not one.

The clawback, and when it changed

3yrFrom delivery, on disposal
2022When one year became three

A foreign buyer not settled in Türkiye who brings the price in as foreign currency can take first delivery of a new dwelling or workplace free of VAT. The three years run from delivery of the unit, and the trigger is disposal. The tax has to clear before the title can transfer. Separately, and on a different trigger: where the exemption was applied without its conditions being met, the buyer who took the exempt delivery is jointly liable with the seller for the tax, the penalty and default interest.

The city Türkiye Bina Deprem Yönetmeliği

“Built after 1999” is not a building code.

The earthquake code, by edition

1998Revised
2007Revised again
2018Replaced them, in force 1 January 2019

AFAD counts seven revisions since 1947. The date that decides which code a building was built to is on its permit, not on its completion year.

A tower completed in 2020, on a 2017 permit, was designed to the 2007 rules.

The city Konutların Turizm Amaçlı Kiralanması Yönetmeliği

One missing signature ends a short-let plan.

Permit conditions where the consent applies

100daysOr fewer at a time, and it needs a permit
100%Of residential owners, notarised
25%The most one lessor may hold, above three units

The consent has to be unanimous among the owners of every residential unit, so the ground-floor shop does not vote. And it is a signature to be collected, not an objection to be defeated: an owner who is abroad or unreachable blocks the permit exactly as effectively as one who refuses.

Not a majority. All of them, notarised.

Between the notes

The unwritten ones are on Instagram.
