It's not proper remediation, it's illegal to not do proper remediation and if you think selling a remediated house might be a stain on your reputation, try selling one where you claim to have remediated it but haven't (which is what this advice is).Meth is nasty, nasty stuff causing advanced and rapid neurological damage in children and pets and slower, but no less advanced neurological damage in adults.  

We have used the shellac/varnish approach fairly successfully with pet odors on concrete floors too.In your case, with the house already painted, if you can find the ozone generator, I'd give that a shot...Kurt

. 😳 I thought it would make sense to have pet owners live with me but it was a big, furry mess!

That said, the carpets are filthy, cockroaches are running rampant, there are probably fleas due to a pet, and I'm concerned about bedbugs. 

They do currently have multiple pets at the property and the lease clearly states no pets so I feel like I can possibly use that to my advantage.      

Many landlords add maintenance charges or pet fees to be paid through Cozy, so to remain flexible, the system doesn't restrict smaller payments. 

Let's say no where in a lease does it state "No pets allowed" or spell out conditions for having a pet such as "Cats accepted with extra $250 security deposit." 

I have been trying to avoid pets (at least medium to large dogs) and getting tenants that have kids.

Not really sure what your goal is in regards to making your life more difficult.There is no logic in a pet owner buying a rattle snake to experience a snake bite.If you want to do section 8 modify your screening for that purpose, concentrate on credit history and previous landlords as most on welfare are not measured by income. 

We have rehabbed houses and apartments that had terrible damage from tobacco smoke as well as pets.
