Hi Daniel, Thanks for your comments. Indeed, I have certainly underestimated housing costs, and at the time when I asked for approval, the list in the wiki was shorter than now. So we need to stay alert.
Last time in 2020, I first asked for 9kEuros, then when the list grew, I asked for 11-12kEuros. I have in fact no idea of how much budget we used last time.... Best wishes, Cédric
