I plan on marketing this property very soon but want to make sure I am not setting myself up for failure here.

I send a letter telling tenants that there was no mold in the bathroom when they moved in and mold growth was caused due to their failure to keep their bathroom clean.4) I evict every tenant who even mentions the word 'mold' because sooner or later you will have problems with this type mentality.

Failure to comply with the process described was, by statute, considered an Unfair trade Practice (UTP).

I eventually bought my own portable ac units in case of failure.  

It was almost like it was too easy so I really would want an opinion of someone who does this or has done this ad understand their success or failure.   

On another building we went with ADT/Protection-One & they monitor our multi-unit fire sprinkler system $100/month but required.Our biggest concern is power failures & sump pump failures of which we've had a few.

Failure to comply allows the tenant to have the landlord use the security deposit towards the rent......this includes failure to just send the letter.

@Anthony Greene The only way you could evict them without good cause ie: failure to pay rent or other material violations of their lease is if you plan to occupy the unit.

The good:Clean cut, well spoken, has 2 verified sources of income (one is a transportation business he owns) and meets our income qualifications, good payment history for the past 2 years according to credit report, good communication with me, jumped through all of my hoops.The bad:While the past 2 years are "clean"....Chapter 7 Bankruptcy in 2013, Eviction (says he co-signed with a girlfriend), 2 divorces (which led to bankruptcy) and a "failure to operate vehicle with license" on criminal report. 

You have proof your claim is true/accurate.I would be interested in your success / failure story.
