The impact of Airbnb on residential property values and rents: Evidence from Portugal

The resource titled "The impact of Airbnb on residential property values and rents: Evidence from Portugal" is published by Regional Science and Urban Economics and authored by Sofia F. Franco and Carlos Daniel Santos. The article aims to provide empirical evidence on how Airbnb's short-term rental market affects housing affordability in Portugal.

The study reveals that a 1 percentage point (pp) increase in a municipality's Airbnb share leads to an average increase of 3.7% in housing prices. In major cities like Lisbon and Porto, this increase is slightly lower at 3.2% per pp rise in Airbnb share. The effects are particularly pronounced in historical centers and areas popular with tourists. For instance, in 2015, house prices in high tourist areas increased by 24.3%, and by 32.3% in the first quarter of 2016, compared to pre-Airbnb expansion levels.

The research utilizes a comprehensive dataset of properties listed on Airbnb, covering 106 municipalities in Portugal between 2012 and 2016. It highlights that the growth in short-term rentals, particularly after 2014, has significantly impacted long-term housing availability and affordability. The article notes that in 2016, there were nearly 45,000 listings on Airbnb, with Lisbon and Porto accounting for a substantial portion.

Prior to 2012, Portugal had strict rent controls that discouraged property maintenance, resulting in many buildings, especially in historic districts, falling into disrepair. The abolition of these controls in 2012, combined with the introduction of foreign investment programs like the Golden Visa, has led to a recovery in housing prices. The number of tourists visiting Portugal also surged, from 13.8 million in 2012 to almost 19 million in 2016, further driving demand for short-term rentals.

In response to the rapid growth of short-term rentals, regulations have been implemented to manage their impact. For instance, the Decree-Law no. 128/2014 simplified the process for homeowners to enter the short-term rental market, requiring only registration with the national tourism register. By 2017, stricter regulations mandated that all rental properties listed on platforms like Airbnb must display a registration number, with fines for non-compliance.

While the article acknowledges that Airbnb cannot solely be blamed for rising housing costs, it emphasizes that the platform has contributed to increased prices, especially in tourist-heavy areas. This dynamic poses significant challenges for local residents, as properties shift from long-term rentals to short-term accommodations, thereby reducing affordable housing options.

The findings of this research highlight the complexities of the housing market in Portugal and the role of short-term rental platforms like Airbnb. As housing prices continue to rise, particularly in tourist-centric neighborhoods, the implications of this trend warrant careful consideration by policymakers aiming for sustainable housing solutions across Europe. The article serves as an important contribution to the ongoing debate about the intersection of tourism, housing affordability, and urban development.
