This ended up being a case of clerical error on their part. They didnt raise the rent at all for the remaining 3 weeks.
As part of my lease agreement, we must give a 60 day notice before we intend to vacate, even when the lease is expiring. The lease says that we are responsible for the remaining time at "a premium rate" on a month to month basis.
We were late in giving this notice by about 3 weeks.
We gave our notice, and expected our rent to go up for the remaining time. However, looking at our rent portal, the amount due is now 6k. 4 times the monthly rent we were paying before.
I understand that the rent is going to go up some, but quadrupling the monthly rent for 3 weeks is completely abusive.
Is there any action I can take? I didn't find any kind of protection for renters in this case, but I feel helpless. If we really do have to pay this amount we will have to default.
Edit: The specific verbiage in the lease is
60 day written notice to vacate is required. Should proper written notice not be provided, resident shall remain liable for rent for the number of days that the notice is deficient, at a month to month premium rate, for all days the Lease is extended beyond the initial Lease Term, until the earlier of: (i) sixty (60) days following the date Resident provides such notice of termination or (ii) the date on which a new resident's lease term for the premises begins.
