Any damage to your property from the tree will be your responsibility unless the neighbor was negligent.

You'd be able to sue him for damages for breaking contract.He would be responsible for refunding the deposit along with potential damages for lost opportunity costs 

Depends on your area - i never place signs on the property as I'm concerned it also tells people the home is vacant and thus damage could be done. 

My plan for resolving this is to have it snaked, then scoped to provide visual verification that there is no damage.

Once you have that covered, put your documentation together and sue the tenant for back rent and damages.

Since the Unconstitutional Eviction Moratorium only covers "Non Payment of Rent," file for eviction under other reason(s) such as damage, disturbing the peaceful enjoyment, threats, etc.

I've inspected the place, he hasn't damaged anything but he does not keep things well.

A friend told me it should be electric, gas, water.Another friend said only electric because if gas and water are turned on, someone could accidentally leave it on and cause damage or run up the bill.What do you all do? 

I heard that not many renters insurance provide pet liability insurance (property damage and physical injury).

We still returned the full deposit even though the rent was owed, water was owed, damage to the home etc....there was a grieving family that needed help and that was one small way we could show compassion.
