As a foreign tenant, there are a few local practices to be aware of. For example, rent is due at the beginning of the month, and late payments are not tolerated. Regarding the security deposit, it must be returned within one month after move-out, and it cannot be used to cover unpaid rent. Punctual payments are very important in France.
For any requests related to the apartment, written communication with the landlord or the property manager is common.
Finally, tenants are responsible for regular maintenance of the apartment and should promptly report any issues to avoid complications. During lease signing, your letting consultant will explain your rights and responsibilities as a tenant.
