I can see the greater complex-wide cycle argument for complex wide amenities, leasing office support, and maintenance request response/resolution times.

Everyone moves out, so the above issues become a higher priority until units are backfilled. Since units are filled, the above issues become less important (to the owners at least, not the renters). Then renters receive this worse service, start moving out in waves, and the cycle continues.

The mold, and in-unit plumbing, and insect issues seem more like routine maintenance types of things to me. But compounded slightly by longer maintenance request response/resolution times.
