That's neither right nor wrong, just an observation that not everyone has the same debt structure as you. 

Make it clear, section X of the lease states...I have observed XX on this date. 

To David's point, I observed the same phenomenon in Rochester at about the time I started liquidating my investments. 

My personal observations.

Yeah, I'm going to call out people who have poor power of observation and can't figure out that as most others have noted, this isn't normal wear and tear.

When it comes to these types of situations, be observant on how the contractor decides to handle things... it can be a big tell on whether or not they are genuine and are someone you should consider working with in the future!

I don’t make appointment to show the unit unless they pre-qualify.And I observe them touring the property.  

They want to see how good the lighting is because they forget to observe it, check the measurements, or maybe they didn't have enough time to really check the place out and get a feel for it the first time.

If u still want to do this how about getting a property manager in your local area this way your kind of hands off and just observe the things they do..if u want to be successful immulate techniques they do.Again this is just way I see things.

Observe the process.
