When you sell an “as is” home, your property is sold in its current state, with defects and all that. The buyer will not be able to negotiate compensation for repairs or ask the seller to fix anything before the sale closes. When a home is placed on the market as an advertisement as is, it means that it is being sold in its current state, no improvements or improvements will be made by the seller. The home may be in great need of repair or may require an update in style and decor.
If a home is listed as is, the buyer is responsible for repairs and modifications, including problems that may not be apparent at the time of sale. When a house appears as is it means that when the house is purchased, the buyer has obtained it exactly as is, with any structural or cosmetic defect. The seller will not compromise on the price and there will be no negotiations on repairs to the house. It's what you see, it's what you get to buy a house.
Alternatively, a home may have gone through foreclosure and is now owned by a bank, or the seller may have died and left the house to heirs or a real estate agent who have little idea what could be wrong with it, but who need to sell it. For homes that are not being sold as-is, buyers can use problems found during the inspection to demand that repairs be made (or that credits be provided so that they can make those repairs themselves). Unless it's a popular real estate sales market and other potential buyers compete with you, the realtor knows that the property won't sell until you get an offer that works for you. When someone asks me if it is recommended to sell their house as is, the answer is almost always no.
Sellers can even make certain corrections requested by homebuyers, if that's the only way they can sell the home.
