I would ask for 2500$ concession to be added to the contract for costs involved in bathroom repair.

Take pictures of them, one up close and one from further back so you can clearly see that it was posted on the dwelling.Now, if you noticed, they have a lawsuit pending with the bank - I would certainly talk to an attorney, to see where you can be added as a party to that lawsuit, to recover damages yourself to compensate you for the elderly couples stay in your property and now your own legal problems, with it.

They expected the landlord to pay for the extermination (which ain't cheap) even though one of their kids brought the bed bugs into the house.Since the TAR lease is silent on this issue I will be adding the following clause to all future leases:"With the exception of wood destroying insects, tenant will be responsible for the extermination of any pests including bed bugs."

wall of the kitchen is one I would take out.My first impression is that a lot of value could be added by knocking walls out and opening it up.

The legal fees will only be around $100, and will be added to what the tenant owes you!

I have seen her mom walked outside the apartment to take out trash int he morning in her PJs.I mentioned to my tenant that if her mom is staying with her her mom needs to be added to the lease. 

I don't want to turn away good renters, but I also don't want to attract tenants that feel a smaller fee is easier to manage, say $25-$50.My Current late charge section includes the following taken from my current lease agreement:"A late fee of $112.00, (not to exceed 8% of the monthly rent), shall be added and due for any payment of rent made after the 1st of the month.

This has nothing to do with being an expert, but is a reminder about knowing the environment in which your business operates and, perhaps it needs to be added, not assuming that if you go to another jurisdiction things will be the same.  

The current lease says any guest staying more than 2 weeks will be added to the lease. 

They all had beads of sweat on their faces and looked miserable.
