Even though it was reported as vacant, we were denied the claim by their carrier, due to there being no working smoke detectors found.

The gurus never tell you that searching through the smoke and the mirrors in the game, extending yourself very uncomfortably into the unknown, being willing to invest and possibly waste your time searching for answers, actually building meaningful relationships, all of that's is a very big part, if not the biggest part, of winning in real estate.When Hannibal was told it was impossible to get his elephants over the Alps to invade Roman territory from the north, he responded with the following:"Aut inveniam viam aut faciam" I WILL FIND A WAY OR MAKE ONE.That's the attitude we need here.

Home is also kind of mess ..with weed smoking in the house and dog poo in backyard not cleaning up after and so forth.How to proceed here ?

We used the insurance company's preferred vendor for the smoke remediation… but we ‘made out like bandits’ on the painting / fixture replacement because they were wrote up  like $8,000 for the work and it probably took us 20 hours of work and $750 in materials to put things back together.  

@Yousuf Kaleem Change the batteries in the smoke detectors.

I assume you have carbon monoxide and smoke detectors in the property.

I'm not just here blowing smoke.

Some specific examples include careless installation of vinyl flooring in our kitchen, resulting in irreparable damage; leaving an exposed nail in remodeled kitchen cabinetry that scratched our new range; installation of bathroom sinks with improper plumbing connections; and multiple instances of failure to remove cigarette butts, food trash, and construction waste from our property.

Tenant B, the upstairs tenant, complained a couple of weeks ago that tenant A was smoking cannabis on the patio (it is explicitly against the rules of the house and is in the lease).

Smoke detectors, missing batteries 6.
