Tehran’s Rental Vacancy Rate Hits New Lows as Tenants Battle for Homes

This summer, the scramble for rental housing in Tehran has reached new heights, with vacancy rates in districts such as Saadat Abad and Vanak reported at less than 2%, according to the Tehran Board of Realtors. Prospective tenants are queuing at agency offices before doors open, vying for apartments that rarely stay on the market for longer than 48 hours. Landlords and brokers confirm that listings are snapped up almost as soon as they appear on Divar and other popular platforms, sparking bidding wars and driving up rental prices in the city’s most sought-after neighbourhoods.

Competition Fueled by Economic Pressure

This spike in competition comes at a time when Tehran’s property market is already under intense strain. The recent sharp increase in mortgage rates, combined with home prices that continue to outpace incomes, has made buying unaffordable for large segments of the population. In early July, the Ministry of Roads and Urban Development reported that the average price per square metre in District 3 had climbed to 170 million toman, while citywide rents posted a year-on-year rise of 31%. The mismatch between wages and housing costs means many households that would once have considered buying are instead locked into a rental market with limited supply and volatile pricing.

Nowhere is this felt more acutely than around Bahar Street and the Mirdamad business precinct, where new infrastructure projects and proximity to major employers make apartments especially desirable. According to agents at Arman Melk, a leading real estate firm headquartered in Yousef Abad, available units there are consistently oversubscribed. “For every vacant flat, we’re seeing five to seven serious applicants,” one agent said, pointing to a backlog of renters displaced from neighborhoods undergoing redevelopment or struggling with expiring contracts and steep renewal demands.

Data Paints a Stark Picture

Data from the Tehran Chamber of Commerce shows the citywide vacancy rate for rental units stands at just 2.6%, its lowest in 12 years and well below the typical market equilibrium of 5%. In the Narmak and Shahrak-e Gharb districts, the figure drops to near zero, while asking rents for a modest 90-square-metre apartment in Niavaran have ballooned to 27 million toman per month—double the rate of three years ago. Meanwhile, new construction begins at a sluggish pace, with only 9,800 building permits issued in the first half of 2026, down nearly 20% from the previous year. Analysts at Bank Maskan warn that unless new rental stock comes online, the current squeeze could persist through early 2027.

With few affordable purchase options and climbing rent, Tehran’s residents face difficult choices. Many young families are now doubling up with relatives in Azadi and Shahr-e Ziba, or extending leases on older stock at above-market rates. Some are even considering moves to Karaj or Hashtgerd for cheaper alternatives, sacrificing commutes for housing security.

Strategies for Prospective Renters

Industry insiders suggest that for those entering the market now, speed and flexibility are paramount. Arriving with deposit documents and references prepared, and checking updates from agencies like Farhang Melk in Golhak or the Kaveh Housing Cooperative, can improve odds. The Municipal Housing Desk, operating from Valiasr Square, has also launched an initiative pairing tenants with landlords willing to negotiate partially controlled increases for renewals. Yet with listings so scarce, experts predict competition will hold steady through the autumn, especially around universities and tech precincts as students and staff prepare for the new academic year. For many, the rental battle in Tehran shows no sign of letting up soon.
