Why Tehran’s Rental Vacancy Rate is at a Record Low—and Competition Keeps Getting Worse

Tehran’s rental market is entering uncharted territory this summer, with rental vacancy rates in June hitting their lowest level in at least five years across central and northern districts. According to data compiled by the Association of Tehran Realtors, the vacancy rate in Districts 2, 5 and 6 now sits at just 1.7%, leaving would-be tenants facing unprecedented competition for even the most modest apartments.

The tightening market comes at a volatile national moment: the death of the Supreme Leader has unsettled economic expectations, while families whose savings have been eroded by currency shocks are scrambling for affordable options. Realtors say hardly any new projects have completed in the past year, as developers delay launches amid uncertainty, compressing supply just as Tehran’s population continues to swell—especially in sought-after districts like Gisha and Vanak.

Renters on Edge From Jordan to Shahrake Gharb

The squeeze is felt most acutely on key rental arteries like Molla Sadra Avenue and Jordan Boulevard. According to Hassanabad-based agent Parviz Group, more than 30 potential renters viewed a single one-bedroom listing off Saadat Abad Street last week—half of them students, the other half young families recently priced out of central neighborhoods. In Shahrake Gharb’s newly built Block 27 tower, all 72 units have been let since May despite rents averaging 70 million toman per month for two-bedrooms. "We see families offering to pay a year upfront, or sweetening bids with cash bonuses to landlords," Parviz Group’s rental manager explained.

In Gisha, a former stronghold for graduate students and young professionals, shopfronts now display handwritten notices: "No available rentals—please check back next week." Many property owners are holding out for higher prices, or simply refusing to lease at all as uncertainty about regulation and taxation grows under the city’s new real estate review committee launched in April. Major sites like Divar and Sheypoor show fewer than 300 active listings across all central districts at the time of writing—a 40% drop from the same period last summer.

Numbers Paint a Stark Picture

Official figures from the Tehran Branch of the Central Bank show average rents citywide surged 38% year-on-year in the second quarter of 2026. In District 2, the median monthly rent for a 90sqm apartment is now 50 million toman—up from 36 million toman in June 2025. Prospective buyers are not faring much better: with mortgage rates topping 21% and lenders demanding down payments of at least 35%, even middle-income families are squeezed out of the purchase market, intensifying pressure on rentals. According to Housing Market Monitoring (Bazresi Maskan Tehran), only 480 new rental contracts were registered across all key central districts in June—a 27% decrease compared to last year’s already tight market.

Experts at Amin Hozour Real Estate Institute forecast that unless substantial new stock comes onto the market or economic conditions sharply improve by Q4, vacancy rates may dip below 1.5% citywide—raising the risk of further rent hikes and increasing homelessness among vulnerable city residents.

For renters, practical advice is now grim: prepare all documents in advance, be ready to make snap decisions, and consider widening your search to neighborhoods further east, such as Tehranpars or even Khaniabad. Several local banks, including Bank Mellat and Parsian, are rolling out emergency microloans for tenants facing large upfront deposits. Watch for new listings early in the week, and expect continued intense competition through the remainder of summer and beyond—unless city authorities launch bold interventions to boost supply.
