Real Estate Contracts: Everything You Need to Know for Your PSI Licensing Exam

If you’re studying for your real estate salesperson license exam, contracts are one of the most important topics you’ll face. In fact, the PSI exam places a heavy emphasis on contracts because real estate agents deal with them every single day. Whether you’re writing up a listing agreement, submitting an offer on a home, or handling a counteroffer situation, knowing how contracts work is not just exam knowledge; it’s your real-world survival kit.

Let’s break this topic down in plain English so you can walk into your PSI exam with confidence.

What Is a Real Estate Contract?

A real estate contract is a legally binding agreement between two or more people regarding a property transaction. It outlines what everyone is promising to do, the price, the terms, the timeline, and what happens if things go wrong. Think of it like a rulebook both parties agree to follow.

For a contract to be legally valid, it has to meet five basic requirements. Miss even one of these, and the contract could fall apart in court.

The 5 Elements of a Valid Contract

These five elements are tested heavily on the PSI exam. Know them cold:

📝 PSI Exam Tip: The PSI exam loves to test whether a contract has all five elements. If a question describes a contract in which one party is 16 years old or signed under threat, look for answers involving “void” or “voidable.”

Types of Contracts You Must Know

The PSI exam will ask you to classify contracts using specific legal terms. Here’s a breakdown:

Express vs. Implied

• An express contract is written or spoken out loud, and the terms are clearly stated
• An implied contract is created by actions or behavior, not words

Bilateral vs. Unilateral

• A bilateral contract is one in which both parties make promises to each other. For example, in a standard purchase agreement, the buyer promises to pay, and the seller promises to deliver the deed.
• A unilateral contract means only one party makes a promise; an option contract is the classic example; the seller promises to sell, but the buyer is not obligated to buy.

Executory vs. Executed

• Executory means the contract is signed but not yet fully performed (closing hasn’t happened yet)
• Executed means everything has been completed; the deal is done

Valid, Void, Voidable, and Unenforceable

📝 PSI Exam Tip: The Statute of Frauds requires that ALL real estate contracts be in writing to be enforceable in court. This is a go-to exam question. An oral agreement to buy a house might have all five elements and still fail in court because it wasn’t written down.

Listing Agreements: Getting the Property on the Market

A listing agreement is a contract between the seller and the real estate broker (not the salesperson directly). It gives the broker permission to market and sell the property.

The four types of listing agreements:

1. Exclusive Right to Sell — The broker earns a commission regardless of who finds the buyer, even if the seller finds the buyer themselves. This is the most common type and the most protective for brokers.
2. Exclusive Agency — The broker earns a commission only if they or another agent finds the buyer. If the seller sells it themselves, no commission is owed.
3. Open Listing — The seller can work with multiple brokers, and only the broker who actually brings in the buyer earns a commission. The seller can also sell themselves without paying any commission.
4. Net Listing — The seller sets a minimum price they will accept, and the broker keeps anything above that amount as their commission. This type is risky and illegal in many states due to potential conflicts of interest.

📝 PSI Exam Tip: Net listings are a warning sign. The PSI exam often uses them to test your knowledge of ethics. The broker’s personal financial interest might conflict with securing the best price for the seller, which would constitute a violation of fiduciary duty.

Every listing agreement must include these essential terms:

• Names of the parties (seller and broker)
• Property description
• Listing price
• Commission amount or percentage
• Duration/expiration date
• Duties and responsibilities of both parties

Buyer Representation Agreements

Just as a seller signs a listing agreement, a buyer signs a buyer representation agreement (also called a buyer agency agreement) with their agent’s brokerage. This contract outlines:

• Who the agent represents
• The scope of the agent’s services
• How the agent will be compensated
• The duration of the agreement

This has become more prominent following recent industry changes regarding buyer-agent compensation transparency.

Purchase and Sale Agreements: The Heart of the Deal

The purchase and sale agreement (also called a purchase contract or sales contract) is the main contract between the buyer and seller. This is where the actual transaction gets locked in.

Essential components include:

• Property description: legal description of what’s being sold
• Purchase price and financing terms
• Earnest money deposit: a good-faith payment from the buyer, held in escrow
• Contingencies: conditions that must be met for the sale to go through
• Closing date and possession date
• Prorations: how taxes, insurance, and HOA fees are divided between buyer and seller at closing

📝 PSI Exam Tip: Earnest money is NOT the same as consideration. Consideration is required for a valid contract; earnest money is optional. However, earnest money demonstrates the buyer’s good faith.

Contingencies: The “What If” Clauses

Contingencies are conditions written into the contract that must be satisfied before the sale can close. Think of them as escape hatches — if the condition isn’t met, the buyer (or occasionally the seller) can back out without penalty.

The four most common contingencies on the PSI exam:

1. Financing Contingency: The buyer must secure a mortgage loan. If they can’t get financing, they can cancel the contract and get their earnest money back.
2. Inspection Contingency: The buyer is entitled to have the property professionally inspected. If they find major problems, they can negotiate repairs or walk away.
3. Appraisal Contingency: The property must appraise at or above the purchase price. If the appraisal comes in low and the lender won’t cover the gap, the buyer can cancel.
4. Sale of Buyer’s Property Contingency: The buyer’s purchase depends on selling their current home first. This is the weakest contingency in a competitive market.

📝 PSI Exam Tip: When a contingency is not met, the contract becomes voidable — the protected party has the right to cancel it. If they waive the contingency, the sale moves forward. Understanding who has the right to cancel based on which contingency failed is a common PSI question type.

Counteroffers and Multiple-Offer Situations

When a seller receives an offer and doesn’t accept it exactly as written, they issue a counteroffer. The original offer is then considered rejected: it no longer exists. The counteroffer is a new offer, and the buyer now has to decide whether to accept, reject, or counter again.

In multiple-offer situations, the seller may:

• Accept one offer outright
• Counter one offer while putting others on hold
• Ask all buyers to submit their “highest and best” offer

A backup offer is an offer from a second buyer that becomes effective if the first accepted offer falls through. The backup buyer must be notified in writing when their offer becomes the primary contract.

📝 PSI Exam Tip: Any change to an offer — even something minor like changing the closing date — creates a counteroffer and voids the original offer. This is a favorite PSI question.

Contract Performance and Remedies

What happens when someone doesn’t do what the contract says? That’s called a breach of contract.

• A material breach is a serious violation that defeats the whole purpose of the contract (like a seller refusing to close)
• A minor breach is a smaller violation that doesn’t kill the deal, but may result in damages

Remedies for Breach of Contract:

📝 PSI Exam Tip: Specific performance is unique to real estate because every piece of real property is considered one-of-a-kind. Money damages can’t truly replace a specific property, which is why courts allow buyers to force a sale. Expect this topic on your exam.

Assignment and Novation

Assignment means transferring your rights and benefits under a contract to a third party. However, the original party usually remains responsible for the obligations unless the other party agrees otherwise.

Novation is different — it replaces the original contract entirely with a new one, or substitutes a new party for the old one. With novation, the original party is completely released from all obligations.

📝 PSI Exam Tip: Think of novation as a complete swap-out. The old contract (or old party) is gone. Assignment keeps the original party engaged. This distinction is a classic PSI question.

“Time Is of the Essence”

When a contract includes the phrase “time is of the essence,” it means that every deadline in the contract is strictly enforceable. Missing a deadline, even by a day can be considered a material breach of the contract. This clause is commonly included in purchase agreements, and the PSI exam will test whether you know its legal significance.

Quick-Reference PSI Exam Tips: Real Estate Contracts

Here are the most common contract traps on the PSI exam:

• ✅ All real estate contracts must be in writing (Statute of Frauds) to be enforceable
• ✅ A contract signed by a minor is voidable, not void
• ✅ Earnest money is not required for a valid contract, but consideration is
• ✅ Counteroffer = rejection of the original offer
• ✅ Specific performance applies because real estate is unique
• ✅ Novation replaces assignment transfers (but doesn’t release liability)
• ✅ Rescission returns everyone to where they started
• ✅ Liquidated damages are set in advance; actual damages are proven after the breach
