What must Vivian ensure before the buyer makes an offer on the seller's property?

Vivian must ensure that both the buyer and seller give written consent before the buyer makes an offer on the seller's property because this aligns with the requirement for informed and mutual agreement in real estate transactions. Written consent is essential to document the intent of both parties and protects the interests of all involved, fulfilling legal obligations and providing clarity in the transaction process.

This practice minimizes misunderstandings, as verbal agreements may not be enforceable in court. Ensuring that both parties have provided written consent also helps to solidify the terms under which the offer will be made and any specific conditions that may apply. This step is critical for moving forward in a legitimate and professional manner in real estate dealings.
