I am helping to treat it but he accepted responsibility and discarded his mattresses and sofa.For the OP, I would refuse the tenant based on other reasons.

It could easily sleep 6-8 people with air mattresses. 

I believe she said she's never bought a brand new mattress, but don't take my word for it, listen to the podcast :)Never bought a new mattress??  

If you were going to be making a purchase in the next 3 years would you keep your money safely "under the mattress" in the bank, or would you place it in the market and accept the risk for the possibly great rewards?

My insurance covered a bioclean company to come and remediate the damage: That cleaning included deoderizing, removing affected flooring and removing and disposing a mattress.

Broken tile, leftover mattresses, etc.; you get the picture.I later learned when they moved they went on to purchase their own home and danged if they didn't advertise for room renters (and pets were allowed). 

There is not much left in the unit but there is some things like a fish tank, mattress, and loads of garbage.

Blood from gun shots,, we let it dry, cut out damaged sheetrock,, flooring carpet & pad cut out and wrapped up like a buritto,, plastic gloves, face masks,,  one guy died in bed,, put the mattress in a tarp and rolled it up and out. 

Deck should have been pressure washed.There's debris and an old truck topper in the back yard.Not a fan of the bathroom with the door opening to the kitchen, but that's a personal thing. 

Bed mattresses and frames, $50-$100.
