How to properly secure a long-term rental? (Process help)

Hello All,

I’m looking to understand the correct process for securing a long-term 1-bedroom (T2) rental (furnished or unfurnished) in the Alpes-Maritimes; ideally Menton, with Nice as a backup. The goal is something stable and functional for the first year while getting established locally.

Coming from a system with centralized property management companies, I’m trying to better understand how this works in France, as the structure seems quite different and I’m running into a bit of a wall here.

I’m seeking guidance on a few specific points:

1. Is a “rent résumé” common practice, and if so, what exactly should be included in a strong French-style rental dossier?

2. What is the best route to find serious long-term rentals locally? Should I focus on real estate agencies, direct landlords, or something else? What platforms are actually effective?

3. Is it generally smarter to secure something temporary first and then search locally?

4. What common mistakes make this process more difficult than it needs to be?

I welcome candid feedback from those who have navigated this successfully.

Many thanks in advance.
