Office rents are unlikely to rise in Qatar until the end of 2010, a new report said on Tuesday.

With high levels of supply coming to the market and dampened demand due to the global crisis, rental rates would be under pressure in the medium term, according to research by global property adviser DTZ on Qatar’s real estate market.

Buildings in Doha’s Diplomatic District commanded higher prices of QR250 ($68.70) per sq m than secondary locations like Grand Hamad Street and Al Sadd where average rental rates ranged from QR150 ($41.30) to QR180 ($49.50) per sq m.
