Answer
To arrange a lease, documents related to the chosen method of transaction may be required: in particular, a notary certificate and confirmation of payment of rent tax are mentioned. The tenant must also send the requested documents in advance.
A single set of documents for all cases should not be inferred from these data. Requirements depend on the property, owner, agent, and type of guarantee. Therefore, the list should be obtained for a specific apartment before viewing or applying, rather than after agreeing on the price.
It is better to separate the tenant's documents, documents for the property, and papers related to the guarantee or tax from the outset. This reduces the risk that the deal will be held up by a missing file or an unclear requirement on the day of signing.
