Why Is The Rate For My Extension Different That My Current Rate
Hosts can have monthly specific pricing, length of stay discount, etc. This mean that when you request an extension the host may have a different monthly rate, etc. meaning the cost of your extension can be higher or lower than the cost of your original booking.
This means tenants ARE NOT guaranteed to be able to extend their stay at their previous monthly rate, and are subject to the hosts current pricing for any extensions.
