A real estate purchase contract sets out what a buyer and seller agree to do, on what terms, and by when. Understanding it takes more than recognizing a signature. You need to distinguish an offer from an accepted agreement, the promises exchanged from the deposit paid, and signing from completing the transaction.
This guide introduces the contract concepts covered in Chapter 12 of the 63Hours course. It is a study guide, not legal advice about a particular transaction.
When does an offer become a contract?
An offer proposes terms. Acceptance agrees to those terms. A counteroffer proposes something different. Start there before worrying about the terminology.
Hypothetical example: A buyer offers $350,000 with a closing date of November 15. The seller responds with $360,000 and the same closing date. That response is a counteroffer, not acceptance of the buyer's price. The seller is now proposing terms for the buyer to consider.
The person making an offer is the offeror; the recipient is the offeree. Their roles can switch during negotiation. On a practice question, identify the latest proposal and whether the other party accepted it or changed it.
In an actual transaction, follow the form's acceptance and delivery requirements. For example, the Florida Realtors CRSP form ties its effective date to the final signing or initialing and delivery. A signature date alone is not a reliable rule for every contract. See the Florida Realtors explanation of acceptance and effective dates.
What makes an agreement enforceable?
Chapter 12 groups the main ideas as capacity, mutual agreement, lawful purpose and consideration. An agreement also needs any formality the law requires for that transaction. A document headed "Contract" does not settle all of those questions by itself.
Consideration is the bargained-for exchange. In a typical purchase agreement, the seller promises to transfer the property and the buyer promises to pay the agreed price. Money is not the only possible consideration: a promise can matter too. The Florida Bar's contract guide explains these basic requirements.
Is earnest money the same as consideration?
No. An earnest money deposit is money delivered under the agreement's deposit provisions. It is not interchangeable with the parties' underlying promises. Study questions often test whether you can distinguish those two ideas.
Do not take that distinction to mean that a deposit deadline is optional. If the agreement requires a deposit, its timing and delivery still matter. Equally, a failed closing does not automatically tell you who receives the deposit. Contract terms, contingencies, notices and the circumstances of the failure matter. The Florida Bar's homebuying guide explains why buyers should understand deposit risks before signing.
Bilateral, unilateral, executory: what is the difference?
| Term | What to look for |
|---|---|
| Bilateral | An exchange of promises, such as a buyer promising to buy and a seller promising to sell. |
| Unilateral | A promise accepted through the specified performance, rather than a return promise. |
| Executory | One or more contractual obligations remain to be performed. |
| Executed | In contract classification, performance is complete. In everyday transaction language, people may instead mean signed. |
An option is a useful course example of the distinction between a right and an obligation. The option holder may have a right to purchase within specified terms without being required to purchase. The owner's obligations, the option fee and the method of exercising that right depend on the option agreement.
A signed purchase agreement can still be executory: inspection, financing, delivery of title and payment may remain. When a question says "executed," look at the context. Is it discussing signatures, or asking whether the promised work is finished?
Why do real estate agreements need to be in writing?
Florida's statute of frauds generally requires a written agreement or memorandum, signed by the party against whom enforcement is sought or their authorized representative, for a land sale. It also addresses leases longer than one year. Section 725.01, Florida Statutes, is the source of that requirement.
The useful study distinction is between agreeing on something and being able to enforce it. Do not rely on a handshake or assume that every writing is sufficient. A transaction-specific question about enforceability belongs with a Florida lawyer.
Which dates deserve attention?
Read the agreement's actual deadlines rather than assuming every form counts days alike. A practical review includes:
- The deadline to accept and deliver an offer or counteroffer.
- The defined effective date.
- Deposit, inspection and financing deadlines, when applicable.
- How and when a required notice must reach the other party.
- The closing and possession dates.
These are different events. Missing one can affect a party's rights even when closing is weeks away. There is no general automatic right to cancel every signed contract; applicable law and the agreement determine available rights. Obtain legal advice before relying on a cancellation or drafting special terms.
Check your understanding
A seller changes the closing date in an offer: acceptance or counteroffer? Both parties sign but closing remains ahead: fully performed or executory? A buyer pays a deposit: does that replace the promises in the agreement? Explain your reasoning, then try the Chapter 12 practice questions.
Self-check answers: Changing the closing date proposes different terms, so it is a counteroffer. A signed agreement with closing still to come is executory. Paying a deposit does not replace the buyer's and seller's underlying promises; it fulfills a separate deposit obligation.
