Maybe it's because my interest rate is so low, but I don't have enough deductions (including my mortgage interest) to itemize.  

As a landlord, you should absolutely, beyond question, have a complete understanding of every item listed in your lease agreement. 

Forgery is a covered item in title insurance.. this to the tune of 15 MILLION Dollars.. they paid but after myself being grilled by the big boys from Miami  LOL.I have one going now on a land locked parcel.. my claim is 450k.. they need to buy me an easement or cut me a check.. they missed that my property was indeed landlocked..

The NNN covers most items and there isn't much else in the warehouse that can fail.  

@Benjamin CowlesYou can have the tenant be responsible for general maintenance (lawn care and such) and minor repairs on plumbing and appliances.It would make more sense for the owner to be responsible for roof/door/siding/HVAC replacements because those are capitalized items for your cost basis for depreciation and if the option is ever exercised...

Second, you will likely find that a major CapEx item can substantially reduce your returns.

This covers your personal items such as clothes, furniture, etc. 

You are required to mail the tenant an itemized statement showing the expenses that you take out of his deposit.

or the units were to be closed.I am sure there are some checklist items we can conduct for a case like this. 

I am aware of Connected Investors and have been listening to them for several years but I have not spent any money on their items mainly because of my medical problems and my inability to work forc the last few years.Connected Investors has recently had a great deal for $297.00 that included all you would need and that using their automation could be done at home.
