Some will be a year term with auto renew for same period, maybe a penalty, maybe only requirement is 30 days written notice.

I'm renewing the leases for a duplex that has 2 units: upstairs (3 bedroom, 3 people) and basement (2 bedroom, 2 people + 3 pets).

Give him written notice that his lease is not being renewed due to his failure to respond in a timely manner and that if he is not out, you will evict.You need to let your tenants know that if they don't respond in X days (30?)

Common fees will include a set-up fee, leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more.

I am planning to reach out to the LLC and inform them of their negligence in this matter, I hope they don't renew the lease with this tenant. 

Would it be ridiculous if me to hire my cleaning lady to clean their unit upon their renewal?

the underwriters won't tell us definitively that they won't cover this episode but they have told our agent that they won't renew our policies.

The agent should be able to give you a guess on what the loss will mean to your next renewal.

If the fees go up, add that amount to the rent increase when the lease is renewed.

Plus you can’t pay “last month” twice - once at lease signing and once at lease renewal.
