waive the owners from any liability

for any potential injuries while inspecting a vacant property. Can this be as simple as shooting an email saying I wont hold the owners responsible? Or is it more complicated?

Why is this even an issue? Homeowners typically have homeowner’s insurance and any injury on their property would by covered by their insurance.

Not necessarily, injuries need to be included in policy which hikes up the cost.
But then again, it may depend on your location. Our basic policies cover windstorm; fire; and contents only.
Feel free to correct me if I’m wrong.

its an abandoned property, its probably not covered.

If it’s an abandonded property, it may not have any kind of insurance.

well anyways, does it have to be formal if you know?
