Suburbs Where Buying Now Outpaces Renting: Istanbul's New Value Pockets

For the first time in a decade, buying an apartment has become cheaper than renting in a handful of Istanbul's outer suburbs. Analysis from the Istanbul Chamber of Real Estate Consultants shows mortgage payments for entry-level units in Sancaktepe and parts of Bahçelievler are now lower than average local rents.

Runaway rent inflation has bitten deep in Istanbul, fuelled by a post-pandemic exodus to bigger spaces and a wave of foreign buyers attracted by the citizenship investment scheme. The city’s rental market, which saw median asking prices jump by more than 50 percent in the past 18 months, is now outpacing wage growth and leaving residents squeezed. In this climate, the traditional assumption that renting is cheaper than buying is collapsing in fast-changing suburbs.

Where the Numbers Flip

According to data compiled by Endeksa, the property data firm, a 2-bedroom flat on Atatürk Caddesi in Sancaktepe, listed this week at TL 5.4 million (USD 165,000), would require a monthly mortgage outlay of around TL 36,000 based on June 2026 interest rates and a 25% deposit. Comparable rental homes in the area now average TL 42,500 per month – a gap that widens in favour of buyers over longer periods due to annual rent increases.

Bahçelievler, once seen mainly as a renter’s fallback, has joined the list. The Mimar Sinan Mahallesi area, steps from the reconstructed Bahçelievler Square, is now one of the few central districts where average mortgage repayments have dipped below median monthly rents. According to Sonar Real Estate’s June bulletin, investors now see net yields fall as rents overtake the cost of financing the same property, a rare inversion that's also emerging in Pendik and parts of Başakşehir.

Crunching the Data – and the Risks

Numbers supplied by the Turkish Statistical Institute show residential property price growth has slowed to 16% annually in Istanbul, down from the record-setting surges of 2023–24. Meanwhile, average rents citywide have increased 28% year-on-year, according to the Istanbul Rent Index. The shift is especially common in segments below USD 200,000, where banks like İşbank and Garanti BBVA continue to offer relatively competitive loans despite broader inflation. As recently as 2022, only border districts such as Silivri or Çatalca carried breakeven points for would-be buyers.

Yet, challenges persist. Experts warn buyers in suburban areas like Esenyurt face maintenance and transit costs that can eat into savings. Meanwhile, legal reforms last year now tightly limit landlords’ ability to evict sitting tenants, pushing many would-be sellers toward owner-occupiers instead of investors.

The ground could shift again if interest rates rise or if foreign demand in areas like Kadıköy and Şişli seeps further into the western suburbs. For renters feeling boxed in by exorbitant hikes, running the numbers in Sancaktepe or Bahçelievler could open a rare window to ownership. Local agents such as REMAX VIA in Sancaktepe recommend buyers scrutinise both annual tax charges and site maintenance fees before making decisions. For now, these new value pockets show that the assumed wisdom in Istanbul’s volatile market can – and does – change with dizzying speed.
