Law 820 prohibits requiring cash deposits as a rental guarantee. What is accepted, and is the norm, is one of two arrangements: a co-signer or a rental insurance policy.
The co-signer. A person with proven means who is jointly liable if the tenant defaults. The landlord reviews their income and history. It has no cost but commits a third party.
Rental insurance. An insurer or guarantor covers the rent and, depending on the plan, utilities and damage, in exchange for a premium. The tenant is assessed once and need not involve a relative. It carries a monthly or annual cost.
Which is better. For a tenant without a strong co-signer, insurance opens the door. For the landlord, insurance shifts default risk to the insurer and usually speeds up handover.
At Andavo we review each application and propose the guarantee that best fits both sides. General information, not legal or insurance advice.
