It’s quite tight. Ideally, it should be at 50% of the rent as we demonstrated in our article on monthly expenses for a student in France. But here, you are at 75% of the rent. It will depend on the agent and their assessment of your file. You might be lucky, and it goes through. But if you can, try to be at 70%, I’ve seen many files pass at this percentage.
If you have several financial guarantors, ensure their solvency, then with an explanatory letter you can clarify things for the agent.
Good luck!
