Well, so far he's not moving, the common area smells like smoke from him, and I'm very concerned about him falling down the stairs, especially with the drinking.

a lot of scenarios put down in this contract  and wording about title (they only had a quitclaim deed)My wife is pushing for it but I'm smelling something fishy and seems to hastily  handled by H&M  Plus they relisted on Zillow (not their own sight) and Zillow is showing $6k lower than their price a month ago. 

can any body give me an estimated cost for a complete gut renovation on a 1,500 square foot home with a 800 square foot basement.

You can probably just copy/paste what you wrote here, into the body of the LOE and be fine.

I am the brain, they are the body type idea.  

Has any body have experience flipping houses in this area?

Doesn't this satisfy those at the OAR and other governing bodies?

Pet owners are not all equal in how they care for their pets and these dogs were never bathed and it was very hard to get the smell out (even after all the carpet on both floors of the house).

The landlord said we would be charged for a prorated portion of the carpet since it apparently smelled of dog in spite of the fact that I got it professionally cleaned.

The Odoban will help to kill the smell.
