But at the same time you'll have all new big ticket items - AC, water heater, roof, stain, etc. 

"Your toilet won't be usable while we're replacing it....you can't walk on the floor in this room while we're staining it, etc."

They told me that I will have to rid all of the appliances due to the extent of the infestation plus another almost 12k in damages not included the brick pavers that have gotten oil stains on.

Trellis that they cut in half and the time to re-stain a new one?

I already have a plumber on the way to check my unit and fix the leak however the downstairs unit owner is saying that I am liable for all the damages to his unit, there are some cracks in his roof and stains on the roof that look like they are from water.

Maybe put a pick-nick table back there to re-enforce the idea, along with a Craig's list used charcoal grill.I'd also have the fence shot with a redwood stain to freshen it up.I'd pick pavers that match the house and the class of the neighborhood.

You never know when calamity will strike like a stain, rip, or even burn. so be ready to replace as needed and not lose your spare. 

The rooftop patio is getting a coat of stain and the exterior wall there is being refinished.

Inspect seams for staining to avoid bed bugs.
