Ed- as Ed mentioned, the newness wears off and the residue is left.

I would caution you against using any mild acidic cleaning agent, a strong degreaser (Krud Kutter) would do just as good, just make sure you don't use a super cheap one because it might leave an oily residue.

I would favor hard surface floors whether tile, linoleum or hardwood/synthetic variants and simply provide some sort of adhesive backed strips of carpet over the hard surfaced floors if dealing with property that requires carpeted living space for handicapped tenants in government subsidized properties & I would imagine greater savings in the long run since I've seen hardwood floors that are over 50 years old!

It is not unheard to have to replace drywall to remove the odour and residue.

THE USE OF OXIDIZERSUsing bleach will (almost) always leave a residual.

Sometimes a steam gun will help soften the adhesive so you can peel it off by hand.

These residual lots will usually be abandoned by owners with taxes due and they go unsold with the municipality taking ownership.

Let's say it has a residual value of $8K.Do that on 3 houses. 

You attach the plate with this special gel adhesive that creates an etched tattoo (as they call it) behind the plate -- so if someone removes the plate it clearly tells anyone who sees it that it's a STOLEN ITEM.https://www.stoptheft.com/support/securityplatefaq...

So, to have an 18 month term with 0% interest or even a 2.99% interest rate, that is a tool in your arsenal worth considering.My husband once used one to purchase the lease residual on his car that was on a lease coming to an end.
