Hi @Ben5852 sometimes, split payment will be available to guests but Airbnb does have a condition on that. On Airbnb, payment for long-term reservations (stays of 28 nights or more) is handled somewhat differently compared to shorter stays.
For long-term reservations, guests are required to pay the first month's rent upfront. This payment is made at the time of booking. After the initial month, payments are due monthly. Airbnb will automatically charge the guest's payment method on file every month on the same date as the start of the reservation. That way, guests don’t need to remember to make the payments each month. Airbnb automates this process to charge their stored payment method. Your guest can also check on the Airbnb help center.
