Which document is a legal written agreement outlining the purchase price and terms for the transfer of real property?

The correct answer is the contract for sale, as this document is specifically designed to outline the purchase price and the terms under which the real property will be transferred from the seller to the buyer. It includes details such as the sale price, down payment, closing date, contingencies, and any other conditions or obligations that each party must fulfill before the transaction can be completed.

Understanding the significance of the contract for sale is essential since it serves as the central document that formalizes the agreement between the buyer and seller, ensuring that both parties are legally bound to adhere to the specified terms regarding the sale. This document becomes part of the legal framework that governs the transaction, providing clarity and protection for both sides.

In contrast, the mortgage agreement outlines the terms of the loan that a buyer may take to finance the purchase, but it is not directly related to the terms of sale itself. The escrow agreement involves instructions for the handling of funds and documents related to the transaction but does not establish the sale terms. The deed of trust is a type of security instrument used in real estate financing, ensuring the lender's interest is secured but doesn’t outline the purchase price or terms for the transfer of property.
