You really need to report this to your landlord - asap! As someone mentioned, it would be in your contract to report any damage as soon as you noticed. Also, I think your husbands thinking is disgusting - these people have probably worked really hard to purchase this rental property and he thinks that by causing further damage to the house he will be able to purchase it off them cheaply. I'm glad you are not my tenants!
Yeah, back off a bit Riss. I know you are new but we are a little more civilized around here
