Questions to bring to your agent or attorney

Write down the facts first: what the odor was, when it started, what caused it, and what was done.

  1. If an odor came from a water problem that has been repaired, how should the past water issue be described?
  2. Does past indoor smoking, tobacco or cannabis, belong anywhere on the disclosure form?
  3. If a former grow room was repaired, what about the electrical or ventilation changes should be described?
  4. How should a sewer backup that was cleaned up be handled, compared with a dry trap that simply let odor in?
  5. If an animal died in a wall or attic and was removed, is that a defect, a repaired condition, or neither?
  6. Should the treatment invoice and scope be offered to buyers proactively or kept ready if asked?
  7. If odor returns after the listing goes live, does the disclosure need to be updated?
  8. What happens if a buyer's inspector finds something the seller did not know about?

Why sellers benefit from being specific

Vague answers tend to create more questions. A disclosure that says a basement had moisture with no further detail invites buyers to imagine the worst. A clear description of what happened, when, and what was repaired, supported by an invoice or a provider's written summary, often reads as reassuring rather than alarming. That is a judgment for the seller and agent, but it is one reason so many agents encourage sellers to document pre-listing work carefully.

Treatment does not erase history. A house that smelled of smoke for twenty years and was then properly cleaned, primed and repainted is a better house to buy, but the seller still knows it was smoked in. Odor that was masked rather than removed carries a different risk: if it returns after closing, the buyer may wonder what the seller knew. That is a problem worth avoiding with the agent's help, not by guesswork.

Terms that often come up in this conversation

Seller's property disclosure
The standard form on which Colorado sellers describe known conditions of the property. Ask your agent for the current version.
Latent defect
A problem not readily visible on an ordinary inspection. Hidden moisture behind finishes is a common example.
Inspection objection
The buyer's written request after inspection, typically for repairs, a credit or a price change, under the contract deadlines.
As-is sale
A sale in which the seller does not plan to make repairs. It generally does not remove disclosure duties; ask an attorney how it applies.
Scope of work
A provider's written description of what was assessed, removed, treated and sealed. Useful as a disclosure attachment or reference.
