I remember when Chris and Babs were living in the rental while they were waiting for 14BC to be repaired from the fire, there were several photos and videos that Chris had posted where you could see how filthy and disgusting the floors had become. There were all manner of stains, food crumbs, insects, and even rodent feces deep down in the carpet fibers. It didn't take long for the carpets to get to an unreasonably dirty state, and they just got worse and worse while the Chandlers lived there.
I can only imagine the atrocious condition that 14BC has become today. We already know about the hoarding, the pets pissing and shitting wherever they want, and even Chris using the floor as a toilet. Imagine all the horrible things that we AREN'T aware of. When the bank takes full legal ownership after the foreclosure, if they decide to refurbish the house instead of razing it and starting over, a lot of work will need to be done. The house will likely need to be completely gutted to the frame. The actual floorboards and at least the lower 1/3 of the sheet rock on the walls will need to be replaced due to animal and human waste (and possibly fluids from rotting garbage) soaking through the carpets and pads down to the wood. All the carpets and other floor surfaces will need to be replaced. Vermin will need to be exterminated and cleaned out. Any offensive odors that have seeped into the structure itself will need to be dealt with. The deck might need to be repaired or replaced, depending on its structural state. All the outbuildings like the Dreaming Studio, the gazebo, and the dog house will be demolished and removed. The lawns and gardens might get ripped out so new landscaping can be done, especially if there is a sprinkler system installed that is damaged. And there could be even more work required that I haven't thought of. It'll be a lot of work and very expensive. And that's assuming the contamination and damage isn't to the point where it would actually be more cost effective to demolish the house and start all over fresh.
