I may even video it as documentation.IF she proceeds with legal action, your best and only defense is that you followed your lease and the law and you have verifiable documentation that you did.

I really just don't want to put myself in a position like many were in the last crash, and it seems free and clear properties is the best defense against a market downturn.

Denver is now a lot bigger than Calgary and is diversified with tech, finance, healthcare, telecommunications, aerospace, advanced manufacturing, tourism, outdoor recreation, transportation/logistics, defense, food and agriculture, and a bustling startup culture.

I'll come to Baltimore's defense as well.

I suggest just take a few days, I've been there,many issues, including a roofing job that I should have replaced but was semi-scammed and convinced to patch up and spent about 6K for that and still have a roof that probably will need to be replaced in a few years, it's infuriating but your best defense is knowledge, start networking in your area, try to join your local FB investor group and post any questions you have there; we have a local FB group in my area and that's gold. 

This may look like its a slow process, but from my perspective, this is boht an offensive and defensive move.

in (partial) defense of the folks with the current issues... it's how they have been trained and raised though too, right? 

Sometimes it’s defense too.

More often it's just a train-wreck waiting to happen.The biggest hurdle (other than the potential liability, including defense costs when things go south, regardless of what the seller would sign off on prior to or at settlement) is the requirement that HOI (hazard insurance) continues to protect the lender and owner. 

I will chime in here in defense of @Engelo Rumora and @Dominique Osbourne.
