Please post an update when they renew or default.

They have failed to renew my entities with the Secretaries of State multiple times, have billed me wrong amounts, and GREATEST OF ALL, have cost my business ~$50K in cumulative TAX PENALTIES due to negligence in filing for a tax extension, failing to walk me through my tax filings and needed payments, and failing to file an abatement promptly.

Can I simply not-renew the lease at its term ?

Once you have leases renewing you can make emptying the garbage you put out part of the yard maintenance for the tenants to complete.

yeah my parents and brother both got home insurance below $2000 that is close to that area, and they just renew it recently too, so I thought our estimate would be correct.... and the option period is already passed, if this doesn't seem to be good deal anymore, we can just back out of it and lose earnest money right ?

Mine is 8.25%, no fill or renew fees. 

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

Offer to let them out of their lease or don't renew lease if not much time left.

Thank you for the thoughtful responses.....I will show them the comps, and start with a $150 bump, which is still very under market.Will go to a lease, and note the projected annual increase of $75-100 at next lease renewal period, to get them in line over time. 

Renewals we are doing small rent bumps of 3% or so.
