Matt,My big change, as a housing provider was when I realized that the "big picture" for me, was to maximize service and value, and then get the highest rents, and retain tenants for the longest period of time.I'll grumble a little, paint over the kid's crayon markings and even wash or replace the carpeting.

" When we bought the home Dec. 17 it had a pet-urine odor in 1 of the bedrooms where we decided we needed to replace the hardwood floors in order to remove the smell.

It could be an easy fix, but it needs to be addressed or you will find droppings and other "nasties" accumulating which will lead to terrible odors that will drive tenants away - if they weren't scarred already.From personal experience, rats can take some time to completely eliminate because when they find a warm and dark place, they tend to nest there.

I was at work and I smelled a chemical odor that I described as "burning plastic".

It knocked out the most foul odors that couldn't be handled with cleaning.

(works great) removing pet odors?

You are literally "hermetically sealing" the odor in.

If the bid + expenses + repairs + unknown = profit then I would go for it.I have something similar now and it is going well.If there were existing plumbing issues you would most likely see evidence, mold, rotten drywall, musty odors, etc.

Now, for possibly the biggest expense of all....SMOKE ODOR!

Even if the pets do not have accidents, carpeting hold the pet hair and odors.
