In multifamily housing, what generally defines 'unpaid rent'?

The definition of 'unpaid rent' in multifamily housing is best represented by the concept of rent that is overdue and legally enforceable. This means that the rent has not been paid by the tenant on the due date specified in the lease agreement, and the landlord has the legal right to pursue collection of this amount.

In this context, overdue rent implies that the rental payment timeline has been breached according to the terms of the lease. It establishes the landlord's ability to take further actions, such as initiating eviction proceedings or requiring payment negotiations since they are entitled to receive the rent that is contractually owed.

The other options, while related, do not encapsulate the full legal context of 'unpaid rent.' For instance, rent that is due but cannot be collected may indicate difficulties in recovery but does not necessarily mean it is overdue from a contractual standpoint. Rent that includes additional charges complicates the definition by introducing variables beyond the base rent amount, which is not the focus of the traditional understanding of unpaid rent. Lastly, disputed rent may suggest that there is a valid reason for the non-payment but does not align with the straightforward definition of rent being overdue and enforceable.
