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.

For 1 year they paid rent on time or say before time, but for the last 1 year they are struggling hard in paying rent, always late, I have been very nice so far,never charged any late fee, kept trying my best to cope with them.Now it's getting worse, there two month rent is due, seems like they can not afford,so they should try cheaper house.my concern is should I give them eviction (1 month) notice now, will it make the situation worse..like they stop paying rent at all, or should I wait until rent becomes current again .I heard if they don't pay rent, then I may have to go to court, since they have two kids court can't evict them, also it may make tenant angry and they may stop paying entirely and may start damaging property also.What is best way to handle this situation....Thanks

Be sure to document any damage findings or maintenance needs (HVAC filter changes, leaking toilets, etc) since this would be legally a unit inspection versus a communication concern.
