A study published in 2017 found that increasing Airbnb listings in a given neighborhood by 10% leads to a 0.42% increase in rents and a 0.76% increase in house prices.[141] According to an analysis conducted in 2016, while commercial listings comprised only 10% of Airbnb's total listings in 25 largest U. S. markets for the period between June 2015 and May 2016, they constituted about a third of host revenue. In markets such as Los Angeles and Portland, Oregon, the share of revenue from commercial listings reached nearly 50%.[142]
In November 2012, Airbnb opened an office in Sydney, Australia, its 11th office location, and announced plans to launch the service in Thailand and Indonesia.[54] At that time, Australian consumers accounted for 10% of the Airbnb user base,[55] and in December that same year, Airbnb announced its strategy to move more aggressively into the Asian market with the launch of an office in Singapore.[56]
Some cities have restrictions on subletting for a short period of time. Airbnb has published a list of regulations and requirements for cities in the United States. In some cities, collection of a transient occupancy tax by Airbnb is required. In many cities, hosts must register with the government and obtain a permit or license.[9] Landlords or community associations may have restrictions on short-term sublets.
