A Purchase Offer Letter is a formal written proposal from a prospective buyer to a property seller expressing the intent to purchase real estate at a specified price and under stated terms and conditions. This document initiates the negotiation process and, once accepted by the seller, can form the basis of a binding purchase agreement under the Statute of Frauds.

In real estate law, an offer letter functions as a contractual offer under the Restatement (Second) of Contracts Section 24. It must contain sufficiently definite terms to constitute an enforceable agreement upon acceptance, including identification of the parties, a description of the property, the purchase price, and the proposed closing date. Once the seller signs an unconditional acceptance, a binding contract is formed. If the seller modifies any terms, it constitutes a counteroffer under common law principles, rejecting the original offer.

Purchase offer letters are particularly important in competitive real estate markets where multiple buyers may submit offers simultaneously. The letter serves both a legal and strategic function -- it communicates the buyer's financial qualifications, seriousness of intent, and proposed terms. In some markets, buyers include personal letters to the seller alongside the formal offer, though several states (including Oregon under ORS 659A.421) have enacted or considered legislation limiting the use of personal buyer letters to prevent fair housing violations under the Fair Housing Act (42 U.S.C. 3601-3619).

When making a formal offer on a residential home in a competitive market where verbal expressions of interest are insufficient and sellers require written offers with proof of financing. When purchasing property in a for-sale-by-owner (FSBO) transaction where no listing agent is preparing standardized offer forms.

When submitting an offer below asking price and wanting to document the justification for the proposed price, such as comparable sales data, needed repairs, or market conditions. When purchasing investment property or a second home where the offer includes specific contingencies related to rental income verification, property management transitions, or 1031 exchange timelines under IRC Section 1031.

When making an offer that includes non-standard terms such as seller financing, lease-purchase arrangements, or extended closing timelines that require clear documentation. When the buyer needs to establish a deadline for seller response to prevent indefinite exposure while pursuing other properties.

Failure to submit a written offer can result in misunderstandings about the proposed terms, loss of opportunity in multi-offer situations, and an inability to enforce verbal agreements under the Statute of Frauds.

Offer price -- state the proposed purchase price clearly. In competitive markets, include how the price was determined (comparable sales, appraisal, market analysis) to strengthen the offer's credibility. Address whether the buyer will cover any gap between the appraised value and the offer price.

Earnest money deposit -- specify the deposit amount (typically 1-3% of the purchase price), who holds it in escrow (usually a title company or attorney), when it must be delivered, and the conditions under which it is refundable. Larger deposits signal serious buyer intent.

Financing terms -- describe the buyer's financing method (conventional mortgage, FHA, VA, cash, seller financing). Include pre-approval letter details, the loan-to-value ratio, and the financing contingency period. Cash offers should include proof of funds documentation.

Contingencies -- list all conditions that must be satisfied before the sale is final. Standard contingencies include home inspection (typically 7-14 days), appraisal, financing approval, title search, and sale of the buyer's existing home. Each contingency should include a specific deadline and the consequences if not satisfied.

Proposed closing date -- specify the target closing date, which must allow sufficient time for loan processing (typically 30-45 days for financed purchases) and title examination. Indicate flexibility if the seller needs additional time.

Offer expiration -- include a clear deadline by which the seller must respond (typically 24-72 hours in active markets). State that the offer automatically expires if not accepted by the specified date and time.

Inclusions and exclusions -- identify personal property, fixtures, appliances, or equipment included in or excluded from the sale. Under UCC principles, items permanently affixed to the property are generally considered fixtures and transfer with the real estate unless specifically excluded.

Buyer qualifications -- provide evidence of financial capacity including mortgage pre-approval letters, proof of funds for the down payment and closing costs, and any other documentation that strengthens the buyer's position relative to competing offers.
