I spoke to the police today and they recommended that the tenants video tape and take pictures as much as possible, harassment charges may be filed.  

If not, and again, I mean here in CO and after consultation with my attorney on this exact topic, I know that if it appears the tenant has abandoned the property and left nothing of value behind that I should walk the unit and video tape what I see. 

Without that, if it appears abandoned, walk through it and video tape what's there.

Then I saw on TV a show around that time where investigators videotaped doctors preparing phony bills for patients for phony visits, I was convinced. 

It isn't very expensive if you sub it out yourself but if you hire a GC, they might try to rip you off acting like it's worse than it is.If it is known that the house has CDW, just video tape some of the demo and the installation, and take lots of pics during demo, after demo to show house down to studs, and new drywall installed.  

Video tape it when you enter.

For creatively financed deals, I've heard of videotaping the closing/contract signing as a means of protection from sellers coming back later saying they didn't understand the proceedings or was duped in an effort to regain their properties (especially after they've been fixed up, appreciated, or you've helped greatly improve their financial situation).

., make sure that either you bring a witness with you, or video-tape the delivery, with date of delivery - best do both, witness plus video taped.

The picture he is looking at from people running event could be a year old.Pay a Realtor or Property Manager to video tape property for you before you spend any money on flying up to check it out.

I'm always afraid of being sued, especially after I read that one guys post how he had an iron clad contract and even video taped the signing.
