A shed is a movable object as is a washer and dryer. . A dishwasher is not a movable object, it is attached to the house. Moveable objects are owned by the seller and may be taken by the seller
Any movable object is not a part of the sale agreement unless included in the sales contract. Apparently this shed was not listed in the sales contract.
Oral agreements and statements are not apart of the contract you signed. These oral agreements are not
normally upheld in a courts.
Even though you have a recording of the real estate agent indicating the shed is part of the property and would stay, in most states, you are required to inform the person that you are recording the conversation. It is illegal to record someone without their approval.
So even if you have a recording you basically have nothing that would be admissible in court.
The real estate agent indicated that the shed would be included, but several weeks later indicated the shed would not be included. Apparently the real estate agent did her home work and confirmed the shed would not be include in the sale of the property.
One of the questions you need to ask before signing a contract is what is included in this contract? Does it include the shed as it is listed as part of the sale.
The real estate agent could have thought as you, that you understood what you were signing, therefore did not think it was important to inform you of anything else.
If the shed is that important to you, you might consider a counter offer to the owner's offer of $2,000, to buy the shed.
Your chance of getting out of this contract, based on the shed not listed as part of the contact, is not great without a financial penalty against you.
I hope this has been of some benefit to you, good luck.
