A real estate purchase agreement is the legally binding contract that transfers ownership of a home from seller to buyer. It is more than a handshake — once both parties sign, neither can simply walk away without legal and financial consequences. Every home sale starts with this document.

What a Purchase Agreement Contains

A standard residential purchase agreement covers:

Section What It Specifies
Purchase price The agreed sale price
Earnest money Deposit amount and where it is held (escrow)
Financing terms Loan type, amount, and financing contingency deadline
Contingencies Inspection, appraisal, home sale (each with deadlines)
Closing date The target date to transfer title
Inclusions/exclusions Which appliances, fixtures, and items convey with the home
Possession date When the buyer can take physical possession
Seller disclosures Known defects, HOA status, environmental issues
Repair negotiation Limits on what seller must repair, or credit in lieu
Prorations How property taxes, HOA fees, and utilities are split at closing

Names for the Same Document

A purchase agreement is commonly called:

  • Sales contract — most common in the South and Midwest
  • Purchase contract — common in the West
  • Offer to purchase — common in the Northeast
  • Contract of sale — common in attorney-required states
  • Real estate purchase and sale agreement (PSA) — used in commercial and high-value transactions

The document is the same regardless of what it is called in your region.

How a Purchase Agreement Becomes Binding

The process has distinct stages:

  1. Buyer submits offer — A written offer that includes price, terms, and contingencies. This is not yet a contract.
  2. Seller responds — Accepts, rejects, or counters. A counter-offer voids the original offer.
  3. Mutual acceptance — Both parties sign the same set of terms. The contract is now binding.
  4. Buyer is notified — Acceptance must be communicated to the buyer. The moment of notification starts the clock on contingency deadlines.
  5. Earnest money deposited — Buyer sends the earnest money check or wire to the escrow account, typically within 1–3 business days.

Until mutual acceptance, either party can walk away with no consequences. After mutual acceptance, walking away has financial and potentially legal costs.

Key Clauses Every Buyer Should Understand

Earnest money clause — Specifies the deposit amount, where it is held, and under what conditions it is forfeited or returned. Read this carefully. Some contracts default to allowing the seller to keep the deposit under vague circumstances.

Contingency deadlines — Each contingency (inspection, financing, appraisal) has a deadline. Missing a deadline can result in the contingency being automatically waived. Track each deadline from the day mutual acceptance occurs.

Inclusions and exclusions — The contract should list every item you expect to stay with the home: refrigerator, washer/dryer, window treatments, outdoor furniture. If it is not in writing, the seller can legally take it. Sellers sometimes remove light fixtures, TV mounts, and landscaping plants if not specified.

As-is clause — Some contracts include language indicating the buyer accepts the property in its current condition. This does not eliminate your right to inspect and cancel — but it does signal the seller may not negotiate on repairs.

“Time is of the essence” clause — Makes all deadlines strict. Missing a deadline is a material breach of contract, not just a minor inconvenience.

Attorney review period — Required in some states (New Jersey, New York, Illinois, Georgia, South Carolina). Typically 3–5 business days after signing, during which attorneys for both sides can modify or nullify the contract without penalty.

Who Prepares the Purchase Agreement?

In most states, the buyer’s or seller’s real estate agent prepares the purchase agreement using a standard form approved by the state’s real estate association. Agents are not attorneys but are trained and licensed to complete these forms.

In attorney-required states (NJ, NY, GA, SC), a real estate attorney must review and approve the contract before it becomes binding. In other states, hiring an attorney is optional but advisable for complex transactions.

What Happens After You Sign

Once both parties have signed and the buyer receives notification:

  1. Earnest money deposited into escrow (1–3 business days)
  2. Inspection scheduled and completed (within contingency window — typically 7–14 days)
  3. Mortgage application submitted (if not already submitted)
  4. Appraisal ordered by the lender (typically 10–21 days)
  5. Title search begins
  6. Loan underwriting and approval
  7. Clear to close — all contingencies met, lender has approved the loan
  8. Closing disclosure issued (required 3 business days before closing)
  9. Final walkthrough (1–2 days before closing)
  10. Closing day — sign documents, funds wire, title transfers
