The LLC just protects you and your assets from a injury claim from a renter. 

Reporting and addressing minor concerns fosters community responsibility within the building or complex.Cons of Allowing Tenant Maintenance:Liability Concerns: Landlords may be held responsible for tenant injuries during property maintenance.

Hello, Would a bank call my note if after buying the property in my name and then transfering the property into a irreversible trust? 

I can't speak on how demo is done in certain states but from what I could tell you being a license contractor here in NY and you being in NJ which should not be much difference is do the following steps.1- have them demo and take everything plumbing and electric.2- the only scrap metal you should keep is copper, but also negotiate with the demo grew to reduce some cost if they want the copper, all other scrap metals are not word it.3- has for the electric, just have them leave you 2 plugs because that's all you need until you update all your electrical. mostly all power tools are cordless so I doubt you will blow a fuse and you don't need any light because you work will be done during the day.ALSO NOTE: do not have anybody mess/touch/remove with any electrical panel or any electrical box, leave that for a license electrician to do because thats a big safety issue that could bring a lawsuit if a non-license electrician gets any injury for attempting to do so.

I'm hoping the lease is good enough that it contains some mention about tenants taking care of the property.My lease specifically forbids pets and in a couple of cases where I did allow pets, the pet addendum states this:  "Tenant accepts full responsibility and liability for any and all damage, injury, or action arising from or caused by tenant's pet(s)." 

To add insult to injury, I also received notice that the property in un-insurable.

MUCH work carries a risk of injury which makes one's lifetime earning potential go down to the point it drastically affects them. 

Would this person need to be insured by himself or will my liability insurance cover any damage or injuries?

Investors generally want to pay for direct labor and direct materials and not pay for the contractor risk (OSHA, aebestos, LNI, litigation, construction defect risk management, lead based paint, surprises, injuries, etc.) 

Not actually a bite, but injury caused by a dog.
