Reversal in Istanbul: Suburbs Where Buying is Now Cheaper Than Renting

For the first time in recent memory, pockets of Istanbul's outer suburbs—most notably Avcılar and Pendik—have tipped into territory where monthly mortgage payments now undercut median rents, according to new property market data released this week.

This rare shift comes as rents across central Istanbul have surged to historic highs, squeezing tenants and changing the calculus for thousands weighing whether to rent or buy in Turkey's most populous city. In a market long seen as hostile to first-time buyers, the current economic and demographic conditions have pushed some outer districts into a different affordability equation.

The Outer Shift: Avcılar and Pendik Lead the Way

Fenerbahçe Park on a July afternoon is busy with families escaping the sizzling city core, but further west in Avcılar, the talk in local realtor offices is about numbers. "If you look at Cihangir or Nişantaşı, buying is still out of reach for most," says a property manager at Kırmızı Emlak, whose small storefront faces the always-busy E-5 highway. "But Avcılar and Pendik—now, there we see monthly mortgage payments for some new projects are coming in lower than today’s rent offers. It’s a surprising turn." From İstasyon Caddesi in Avcılar to the recently redeveloped coastal strips of Pendik, brokers are reporting a jump in interest for mid-sized flats where the math has flipped. Official listings show new 2+1 apartments in Avcılar going for around 3.2 million TL, while median monthly rents for similar units now exceed 25,000 TL. With standard loan terms and a 20 percent down payment, principal and interest repayments can sit below 23,000 TL monthly—sometimes even less if buyers manage to lock in government-subsidized or bank promotional rates.

Meanwhile, across the city in Kartal, rents have inflated nearly 19% year-on-year, according to end-Q2 figures from REIDIN, the real estate analytics platform. But the increase in sale prices has not kept pace in specific projects, especially where developer discounts linger in response to sluggish demand from foreign investors.

The Numbers: When Mortgage Beats Rent

REIDIN’s June report outlines the trend clearly: the average listing price for a second-hand apartment in Avcılar stands at 3.1 million TL (about $94,000 at current rates), while average rent for similar properties now stretches beyond 25,000 TL per month. Taking a 10-year fixed mortgage from a major lender such as Türkiye İş Bankası, monthly repayments on these homes would fall between 20,500 and 22,300 TL.

Pendik, historically more affordable due to its distance from central Istanbul, has followed a similar path. One new development, Park Panorama Sitesi, is moving 3+1 apartments at 4 million TL, compared to rental listings in the same compound between 28,000 and 32,000 TL per month. Factoring in entry costs—stamp tax, title deeds, and agency fees—buyers must still have significant upfront capital, yet the gap between ownership and leasing narrows dramatically in these districts. Notably, demand from foreign buyers, buoyed in recent years by the citizenship-by-investment programme, has shifted to central and coastal areas. This has left select western and Asian suburbs competing more aggressively for resident-owner households with price incentives and bank partnerships.

Overall, Istanbul’s city-wide sale price per square meter hit $2,500 by June, with upmarket areas like Beşiktaş and Beyoğlu commanding nearly double. Yet in Avcılar and Pendik, headline sale prices have barely outstripped inflation, even as rents exploded with post-pandemic migration from Anatolia and a tight rental stock, according to Istanbul Chamber of Real Estate Agents.

What Prospective Buyers Should Watch

Analysts warn that the rent vs. buy balance is fragile. Any jump in lending rates or a significant uptick in property values could quickly re-tip the scales toward renting. Yet, for now, would-be buyers in Istanbul’s fringes—especially debt-free upgraders or those able to amass a 20% down payment—have a small but real window where buying is less expensive month-to-month than renting. Buyers should consider extra costs, including DASK earthquake insurance (mandatory citywide), building fees, and prospective maintenance expenses. Most critically, developers in Avcılar (particularly projects closer to the planned Metrobus expansion) and Pendik (near Sabiha Gökçen Airport) are offering time-limited discounts and mortgage deals. For renters watching their leases end, now could be the moment to crunch the numbers. As the city’s rental market remains volatile, the suburbs are quietly offering rare deals to those looking to put down more permanent roots.
