The project HousErasmus+ tackles an obstacle for mobility: the lack of affordable accommodation for international students and trainees during their mobility period. In particular the hinders faced by exchange students as one of the main beneficiaries of Erasmus+ are examined. The project aims to provide a comprehensive mapping of the nationally, regionally and locally diverse situation for international student accommodation in chosen European countries. The housing market is in general determined by national legislation and often shaped by regional and local policies. However, this project aims to take note of the local factors, choose focus areas where to conduct study visits, perform further in-depth analysis and draft policy recommendations for the European level in terms the best practices found.The project includes several stages; the initial mapping and choice of focus areas, study visits and surveys which address all main actors involved (students, International Relations Offices, municipalities/regions, housing providers etc.) which all contribute to concrete policy recommendations on how to improve the situation. Using the acquired knowledge, regional conferences will provide a space for capacity building, peer-learning and gaining further insight of the field. Further refining the results for a final conference in Brussels, the project will extensively disseminate its finding and effectively raise awareness for both the policy recommendations and the challenges accommodation poses on mobility.The project will contribute to making higher education more diversified and competitive through an increased capacity to manage international student flows. As the lack of affordable student accommodation is a bottle-neck for international student and trainee mobility, it is pivotal to address this challenge and initiate effective policy reform on European level to ensure competitiveness and socio-economic diversity of a growing number of mobile citizens.
