In essence there is usually a fee associated with it and that fee is paid by the tenant if the tenant caused the issue.  

A tenant who can't come up with whatever the amount is may well cause issues down the road this helps them too-it is like money in the bank, and we have always been fair returning deposits.

Yes, it would cause hassle for the current tenant, but why is that a deal breaker for you?

Your rental has a far greater threat of your tenant causing a fire than a tornado causing damage.

Also as @Bjorn Ahlblad, mentioned most of the drainage happens along the length of the drain so the end being clogged isn't a likely cause of water in the basement.

It'll just cause confusion and anger.

My wife and I(no kids) are currently renting a place a 2 bedroom condo with 2 underground parking for $1430 and I recently I have been thinking of buying a house cause I want to get things rollings a bit.

It's not like a survey easement or something that can come back and cause an issue in the future.Good luck on your deal!
