Floor for dirty, smelly, never-clean-up with 80 lbs dog

[Jin Kim]

This unit for section 8 tenant did not pass the inspection this month. In order to pass the 2nd test, we will have to 1. replace the carpet, 2. find the door knob for shower door, 3. door knob for oven as well. 

This tenant moved in 2009. We took over this property just a few month ago. 

I thought we will change to heavy duty laminate instead of carpet again. But my contractor thinks that laminate will be scratched anyway and downstairs will complain as laminate makes noise. And I've been researching around on the internet it looks like "wood like tile" seems very durable solution. but my contractor told me it's very pricy - 3 times more for material, 2.5 more for installation. 

How much do you spend to re-floor the 1 bed apartment? and what would be the best option for this case. I went inside a few times. the whole place totally stinks and it looks like he has never cleaned for many years. spider webs are everywhere. Plus he has a big dog. I wonder if the dog is potty trained and if not, the tenant actually cleans up after the dog. 

what kind of floor do you install if you accept dogs?
