The seller should have the advice and guidance of an attorney with respect to a brokerage agreement. Even if the agreement is a standard form, its terms should be explained to the seller and revised, if necessary. An attorney should also determine if the agreement was properly signed.

Even if a lawyer is not needed during the course of negotiations, the buyer and seller each may have to consult with a lawyer to answer important questions, such as the tax consequences of the transaction. To a seller, the tax consequences may be of critical importance. For example, the income tax consequences of a sale, particularly if the seller makes a large profit, may be considerable. An attorney can advise whether the seller can take advantage of tax provisions allowing for exclusion of capital gains in certain circumstances.

The purchase agreement is the single most important document in the transaction. Although standard printed forms are useful, a lawyer is helpful in explaining the form and making changes and additions to reflect the buyer's and the seller's desires. There are many issues that may need to be addressed in the purchase agreement; below are some common examples:

• If the property has been altered or there has been an addition to the property, was it done lawfully?
• If the buyer has plans to change the property, may what is planned for the property be done lawfully?
• What happens if a buyer has an engineer or architect inspect the property and termites, asbestos, radon, or lead-based paint is found?
• What if the property is found to contain hazardous waste?
• What are the legal consequences if the closing does not take place, and what happens to the down payment? This question raises related questions: Will the down payment be held in escrow by a lawyer in accordance with appropriately worded escrow instructions? How is payment to be made? Is the closing appropriately conditioned upon the buyer obtaining financing?

Most buyers finance a substantial portion of the purchase price for a home with a mortgage loan from a lending institution. The purchase agreement should contain a carefully worded provision that it is subject to the buyer's obtaining a commitment for financing.
