I'd prefer to sign a new lease, but how do I managed the damages deposit?

She quit her job two weeks after starting so we went to inspect the unit and discovered about $1,500 in damages.

Tenants probably want the bedroom to be a bedroom.You also run the risk of tenants damaging it or being hurt by it when their 5-year-old boy attempts to lock his sister in it. 

When you do loose one it's a bit costly as most jurisdictions award double or triple damages but a loss is rare.

That's when you can see the layers and layers of damage that has been going on for weeks, months, or worse years without you knowing at all.#4  Control -  Are there problems in STR?   

That's $1,000 in late fees and you still have to deal with cleaning, damages, unpaid rent and utilities, etc.When a charge is due, they should pay it. if they don't, get rid of them or they will continue to cause problems.

I've read around these forums that the industry-standard is to boost rent $25 for a pet, which seems reasonable.That said, I wonder whether the presence of a dog also subjects landlords to liability for damage or personal injury caused by the pet.

I’m not sure if I want to vent or ask for advice...My condo had a substantial flood on Thanksgiving, Nov 22, due to a main line pipe underneath the building getting backed up.There is significant damage and the unit is unlivable.

What logic is there in the weight of a pet to the damage it can cause?

That caused water damage under the laminate floors.
