It is easier to parse it out, but still, not as valuable as I would like.

Quote from @Danielle Levy: Lesson learned: provide the full story up front and you'll get better advice.If you feel there's a case, put together all the evidence.

I love how Airbnb just pay me based on the evidence without going through 6 months legal battle or 3 years of collection hunting. 

Then the tenant will rant a bunch of nonsense, have no evidence to back up his stories, and the judge will find in your favor based on the evidence provided by you.For future tenants, I highly recommend you read a book like mine or "Every Landlord's Legal Guide" by NOLO.

The city wants to tear the property and surrounding properties down Zillow said it’s worth 38000The city offer me 13000.I could use some adviceHard to give advice with limited information, but as a general rule, the longer you wait and the further down the line their project is the more valuable your property will be to them.Zillow (and all automatic online) estimates are very unreliable, so don't base on that.

I wanted to use the camera footage as evidence in a civil case against the tenant.I was initially told that it would take 2 weeks to get the footage to me, then that blew out to several months, and now finally 6 months later they finally get back to me and tell me the footage doesn't exist, even though the initial report said cameras were activated.That footage would have shown that the tenant was making threats to damage my property (which she made good on).Do I have any recourse on the police for failing to provide the footage on a timely basis?

Then, gather evidence like recent sales of comparable properties to support your case.

Without evidence, it's hard to say.First, you should educate all of your tenants to report excessive noise to the police.

Are there any guidelines or best practices (ie: rewiring such a property would be more valuable than updating insulation).Is it something you need to ask the insurance company about to get, or is all this determined in the initial interview with the potential insurer?

If you have evidence of the damage, it is unlikely the tenant will spend the time and money to take you to court.
