house had pet, mold and smoke odors..just the smoke lingered.

I would require a pet deposit.

It sounds like you have only had it for 6 months but if it has been longer think about raising rent, have renters pay for utilities or pet rent.

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!

Close to lots of retail, walking distance to coffee shops, new breweries, also large big box stores (Home depot, pet smart, gym, etc) and close to I-76. 

The tenant has violated the terms of the lease: no pets. 

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.
