Rent shall not abate:
In the lease it talks about rent shall not abate. What this clause means is that rent shall remain in full force and effect and tenants obligations to make all payments of rent and other charges when required shall remain unabated.
There may be times, due to maintenance etc. that tenant's will request that there be a deduction or an abatement of rent. The lease states that rent shall not abate, so rental payments will still need to be paid.
