> Does anyone know in general why rental properties aren't negotiated further in advance?

Because it’s a game of chicken between the landlord and the tenant. The landlord usually has some rules for notification (e.g., 30-60 days before expiration) and the tenant usually has something similar for notice to leave.

Nothing stops either from notifying or agreeing to a longer agreement before the old one expires. Though with larger buildings (vs individual owners) it’s less likely they’d be willing to diverge from their standard operating procedures and timelines.
