Selling a house as-is means the seller will not make repairs or give credits for problems the buyer finds, and the buyer takes the house in its current condition. It does not erase the seller's duty to disclose known defects, and a buyer can still walk away after an inspection unless the contract says otherwise. In Tennessee, an as-is disclaimer can replace the standard disclosure form only if the buyer waives it, and a handful of required disclosures, such as a known sinkhole, still apply regardless.
Why it matters
Agreeing to sell as-is does not remove your duty to disclose what you already know is wrong with the house.
In Tennessee: Tenn. Code Ann. § 66-5-212. This can work differently in another state.
