Finally what works for me as a well as other direct mailers  use full size 81/2 x 11 sheets folded up to fit into an invitation size envelope and don't  seal it.

From an ex-carpet cleaners point of view - one who was ceritified as an official Odor Control Technician, I'll have you know (lol) - the only way we could guarantee the complete odor removal was to replace the pad and seal the floor with a shellac-type sealer.

Exterior doors weren't properly sized or installed - neither sealed or were actually closed even when locked.

I plan to take it apart this summer and clean the burners (hack saw blade to the slots) and seal up any gaps in the cast iron puzzle pieces that comprise the combustion chamber (but first I will blow theatrical smoke inside the chamber in order to suss out where any potential leaks might be).

If the house has any carpet with the dog urine smell left, remove a small piece, put it in a sealed baggie as evidence to show in court. 

Send someone or go yourself and seal up the outside foundation or other holes best you can.

The scarier thing is them wanting to seal Eviction records even for nonpayment!

I thought I had a few leads but nothing was an actual deal.My question is what are some ways to seal the deal ,get more calls, and what can I do if I missed calls and the seller doesn't leave a message.

I pay the cost of the permits.To demo the whole house - $3,000 plus I pay for the dumpsters.New Roof - $3,000 Waterproof basement - busted up concrete and installed french drain system  fed into sump pump (kept existing sump pump) and water seal paint the inside (no outside work) $5,000.Frame whole house - $3,000 (basically basement and main level.. upstairs didn't really change)Drywall - delivered, hung, and finished - $32 per sheet he estimates 120 sheets needed ($3,840 total)Insulate all walls and attic - $1500(*) Rough electrical including permits,new panel & wire - $4000  (outlets, switches, cans, fixtures, etc. additional)(*) New duct work - $4,000 ... seems fairly simple with the house demo'd and being such a small house. 

It would cost 150-400 for the material and take a couple hours to install.The laminate would never last long enough though even if you sealed every crack with silicone and followed the directions with putting on end caps, chips, burns and cutting marks would still show up.
