The resident tenants upstairs constantly moving due to smelly odors, and noise downstairs late into the night.

I would be grumbly about it but would spend the $.

Should I pay for a commercial ozone odor eliminator out of pocket?

Odors lurk, so the carpets are usually replaced. 

Looking for tried & True products for combating Cat & Dog Odor on concrete slab foundation.Thanks.

Is there an odor?  

Sometimes you get rid of stains but not odor, and sometimes it's the other way around.

Hi Calvin, I looked at that one too as it could be a good deal.It's definitely going to be more than 10k based on the details in the MLS:"Just vacated by tenant; Needs cleaning and the flooring is likely to need replacing throughout; Please be aware there is a STRONG PET ODOR in the house and pet damage in places; One window has broken glass and one shower is not usable; I believe one of the toilets is not functioning as well.

My policy has been to either use cheap materials that can easily be replaced between tenants with minimal grumbling, or pay for durable, tenant-resistant materials.

@Robert VorhiesKills subfloor paint/sealer.Just had to use it on a flip to kill cat odor.
