There's obviously stupidity and negligence on my part as well, but that is why I hired a home inspector, so that I didn't have to comb through the property. 

Am generally not a fan of inheriting tenants and if I do, I prefer that my lease be implemented, but clearl y that is not always realistic.Thank you though for this suggestion and I am going to try to see if working it from your suggested angle will work here in Colorado.In the end, I want to set up a lease that does not have holes, that an attorney, God forbid we ever have to evict (though these tenants do not seem like the type to cause any issues and I generally am a good landlord and stay away as long as you are following policy, so thus having a detailed lease that covers most all and then just backing off.My inspections are generally once a year, outside of the move-in, move out.I also stay very engaged in the running of my property, thus self-managing as in the end, I strive to provide a place I would enjoy living and I actually live on one of my properties.Long story short, don’t care for the very vague lease that the current property management company has running.Additionally I have little confidence in the way they were managing the property.The property has so much potential but has clear signs of neglect and I intend to change that as I never simply abandon my properties.On the question of current lease, I have combed through it repeatedly and do not see any mention of what happens at lease expiration only what happens when tenants are seeking to terminate their lease, “30-day written notice required”.No stipulation on what is required of landlord at end of lease and/or automatic renewal, both items that I cover in my lease and another reason, why am not a big fan of the existing lease.Leaves out a lot.I prefer having systems in place where there is little chance of misunderstanding, so thus the nerves on this one, but I will get through, thanks to you all for all your great advice!

Obviously, you can't do that for every single real-estate project, but it's not a bad idea to comb over the documents and ask any questions you may have. 

I like when my clients go over their returns with a fine tooth comb before I file! 

I've recently combed through all the Zoning Board of Appeals documentation for the last couple of years (and I had done the same back in 2014) and in almost all cases the board denies requests to re-establish rights. 

I am combing through my local certified 2017 appraisal roll to build a targeted marketing list.

Purchasing involves combing through perhaps hundreds of candidates over a period of months, creating a short list, visiting properties in person, bidding, hopefully winning one, then managing a rehab, and then interviewing property managers, and then hiring one.

Ours (Green Remodeling) was not expecting the city to go through it with such a fine tooth comb.

Sorry I've absolutely combed forums looking for the catch in this method and I can't seem to find these specific answers..BTW, thanks SO much you both are insanely helpful. 

I’d be glad to comb through them for ones that suits both our interests.
