@Wes EavesThe fact that it's inside the house is even more of a reason to replace it early rather than waiting for a catastrophic failure.

I have had great success, and great failures on this.  

Mean while I had my second inspection failure on 8th september (which I came to know yesterday from my PM).

I still don't know if I'd evict for failure to pay late fees.

As other folks have mentioned, googling for the model number and problem will often turn up a solution.Exactly, I goggled the internet to troubleshoot our perfectly good 5 yr old dryer & found the gas valve solenoids are a common point of failure.

And you lease should be written such that both the unapproved "upgrade" and the failure to pay for the damage are grounds for lease termination. 

Could this be one reason this is so, considering the vast majority of bank failures this year?

Failure to do so represents a violation of the agreement.

Like others have said, make them use a deposit slip with the address on it-and- find a bank that posts pics of those slips online.I have a bank that does real-time images of the deposit, so I simply log-on and see the amount, the pre-printed address on the slip, and the timestamp.Also the money automatically sweeps out everyday so no major security concerns.On my payment instructions I tell them "you must use either the pre-printed deposit slips or you must write your address on a blank deposit slip provided by the bank..blah blah....Failure to do so may make you subject to a late fee "

I've never been scared of failure in the sense that I know to succeed in a biz like this, you actually have to fail a certain number of times.
