The lease states if there are any severe damages caused the tenant will be evicted immediately, but we have given them a week to vacate the premises. 

A tenant recently moved out of my property after submitting their 30 day notice. The 30 days ended on August 5. I noticed on August 6th that the tenant's car (not running) was still in the garage. I am wondering about...

I have never understood why landlords would let their units sit vacant. 

The more folks I met, the better I understood investing strategy, execution etc.

I mean, if your wifi or power goes out, you’ll temporarily lose access to the lock - this is understood (though depending on the lock model, guests may still be able to use codes that were already sent in).

I had security cameras installed on the premises, is that considered tax deductible as well?

This only means that you will not be removed from the premises prior to the dates outlined above.

@Oleg MikhailovI agree with your premise.  

As soon as I understood those two principles, I began to learn how to differentiate between an asset, and liabilities that seemed like assets. 

At my other single-family properties, I require them to at least:-Provide limits of liability to third parties in an amount not less than $100,000 per occurrence-Provide coverage for bodily injury within the Premises and damages to the Premises for no less than the following causes of loss: fire, smoke, explosion, backup or overflow of sewer, drain or sump, and/or water damage-Pet liability coverage for bodily injury or property damage with all pets & breeds listed on the insurance policy-Tenant to ensure that the Rental Policy identifies the Tenant as the primary insured and Landlord as an additional insured. 1.
