While a pet lover I don’t need the headache or riskJust search BP for “Urine” and see how much trouble and how much $ people have spent trying to get that odor out.

Not necessarily smoke and pet odor free, but empty of all personal belongings.

Ozone and maybe replace the carpets if cleaning them doesn't take the odor out.

After calling a few people I found out that the best companies will actually come out for 2 years after the initial cleaning to make sure all residual odors are eliminated.Cogo is charging me 12% interest and there are a handful of other closing fees attached to that.

With pet odors it can get difficult to remove the deep-set smell, since the floor beneath your carpet could be the reason for these odors too.

Can't really put my finger on it but smells sort of like body odor, cigarette smoke and uncleaned clothes.

Took 6 months and we had to LITERALLY use respirators to walk inside the house because the odor / fumes were so bad from the cats...

I'll track down a company who can identify the odor and perform the cleaning and get itemized receipts. 

I agree with everything above, and let me add this.Their first child is born in that living room = +$30KThey build this UGLY raingod totem in the backyard = +$15KThey added $315,375.05 in "upgrades" in a $104,466.03 average home value area and thus = +$400K15 years ago, they bought the house for $400K and thus the house is worth X + $400KLand = $X, House = $Y thus everything is worth $X+$YFSBO (Florida Seniors with Bad Odor) are often uneducated on the market.

I will say, most cabins are on well water, which can be tricky - the water can be very mineral-y and, depending on the well and conditions, can have an odor (sulfur) or some color.
