What is a good "out clause" to use in a lease option when you are the initial leasee, but do not want to scare the seller with a clause that the end tenant could abuse?

Can I deny section 8 tenant based on the credit score/history/salary history?

If the insurance company figure out you did unpermitted work and can blame that for your claim, they will deny you claim.

I instructed my agent to send the report to them anyways, so they cannot deny knowledge of a huge problem.

Also, is it common for the insurance company to conduct a very thorough investigation to see if the fire is due to landlord's negligence so that they can deny the claim?

Another problem I see, is if repairs are as a result of tenant abuse, which then becomes a dispute between tenant and property manager.

If not I would deny on the basis of insufficient credit info.

A processor is not an underwriter and does not approve or deny your loan.Usually, this is where all the third party services are ordered such as appraisal and title commitments and closing protection letters.

They are not slippery even when wet, they hold up to abuse, and they are easy to clean.

I just learned something new with this tenant: you cannot deny a service dog.
