Still in due diligence and have alerted buyers agent that we will be going back to seller with a discount on the offer to take into account the odor remediation.

Just don't put down a new floor covering too quick, give it a few days and see if the odor is sealed.  

Once we had a full sand and poly done the odor was gone.

I've heard OdoBan is good for removing the odor from pet urine.

But does regular vaping cause damage or odor?

Oil based is the only kind that works to eliminate odor.

The first one got fouled up and the closing funds got sent to the wrong person.

Otherwise, new underwriting standrds and exceptions will need to be devised and I don't think they will go there.Lastly, problems will most likely arise when something goes wrong, maybe when you attempt to foreclose and the borrowe cries foul.

They garantee odors to be gone.

I would think it would be impossible to have dust free, odor free, noise free, perfect house and yard for renters at the same time you are actively remodeling it.
