Pee You Your Home Stinks!!!!!!!!!!!!!!!!!!!!!!!!!!!

Homebuyers don't want houses that stink. Sellers must identify and remediate odors that make prospective purchasers hold their noses and run for the exits. Unfortunately, it's not always easy for sellers to identify familiar smells that might be problematic. There is no odor meter people get used to the odor of their house and may not notice that something is not pleasant

Outside sniffers
The best way to find out whether a house smells OK is to ask someone who doesn't live there to come inside and give an opinion. The obvious "someone" would be the real-estate broker hired to sell the home. But not all brokers will point out that a house smells bad, even if they're willing to offer other helpful suggestions.
Some agents are not outspoken about odor issues, instead they rely on other agents who bring buyers to see the property to break the bad news. That way, the message gets delivered with less risk to their cordial relationship with the sellers.

Pet odors
The two most common sources of difficult and offensive odors are pets and cigarettes, neither of which, is easy to remediate. The point might seem obvious, but the first line of defense in any smelly situation is to remove the source of the problem, even if that means a beloved pet must board elsewhere for a while.
It's not the nicest thing to do but you have to present the question to them "would you buy a house that smells like a dog or cat if you don't have one?" Cat urine, among the worst of the bad odors, can seep into carpet fibers, carpet padding, concrete and wood floors, upholstery fabrics, and furniture cushions and pillows.
Oftentimes you have to remove the carpet, remove the pad and seal the floor, and then replace the carpet and the pad.

No smoking
Cigarette smoke can cling to furnishings, drapes and other window coverings and work its way inside walls. Some topically applied solutions can help to reduce the stench, but an ozone generator, hydroxyl generator or air scrubber should be more effective. Experts find these methods very effective in absorbing odors, though there is no guarantee that an odor can be eliminated.
