Which of the following does not need to be specified in an offer to buy real estate?

A) A description of the property
B) The price of the property
C) Designations of which party will bear the costs of repairs needed on the property
D) None of these choices is correct.

In an offer to buy real estate, it is essential to specify a description of the property and the price of the property to make the offer valid and enforceable. However, designations of which party will bear the costs of repairs needed on the property are typically negotiated and agreed upon after the initial offer, often as part of the inspection and due diligence process, rather than being a requirement for the offer itself. Therefore, all the choices listed are elements that can be part of an offer, but not all are strictly necessary to constitute a valid offer.
