Why Sellers Should Require a Prequalification Before Accepting an Offer

A strong offer is more than a price. It is also a buyer’s ability to reach closing.

That distinction becomes especially important when mortgage rates are elevated. Freddie Mac reported an average 6.71% rate for a 30-year fixed mortgage on September 3, 2026. At rates like these, the same buyer may qualify for less than they expected, face a higher monthly payment, or need to reconsider the loan amount after making an offer.

For a seller—especially one selling without a traditional listing agent—accepting an offer without reviewing the buyer’s financing can create avoidable risk.

Why mortgage rates affect contract strength

When rates rise, monthly payments rise even when the sale price does not. A buyer who was comfortable with a home at one interest rate may be stretched at another.

That can affect:

• The maximum loan amount the buyer can obtain
• The buyer’s debt-to-income ratio
• Required cash at closing
• Whether the property meets the lender’s appraisal requirements
• The time needed to complete underwriting
• The likelihood that financing conditions change before closing

OfferPath’s current Maricopa County research shows a market operating under tighter affordability conditions. The direct MLS source confirms 42,703 Maricopa County closings in 2026 through the current reporting period. Our county also separates county-linked MLS transactions from possible off-market and excluded/nonmarket transfers so unlike transaction types are not presented as if they were identical.

The lesson is not that a financed offer is weak. It is that sellers should evaluate the quality and readiness of the financing, not only the purchase price.

Ask for a current prequalification or preapproval letter

Before accepting a financed offer, a seller should request a current letter from a lender showing that the buyer has been reviewed for financing at an amount consistent with the offer.

Lenders use the terms prequalification and preapproval differently. According to the Consumer Financial Protection Bureau, either type of letter can provide useful information about a buyer’s likelihood of obtaining a loan, but neither is a guaranteed loan offer.

A stronger letter generally reflects more lender review. The seller should look for:

• The buyer’s name
• A recent issue date
• A loan amount or purchase-price range that supports the offer
• The expected loan type
• The lender’s name and contact information
• Any important conditions or assumptions
• An expiration date, when applicable

A letter issued months ago may no longer reflect the buyer’s credit, income, debts, available funds, or current mortgage rates. If the letter is stale or the offer is materially higher than the amount shown, ask the buyer for an updated letter before acceptance.

Prequalification is a screen—not a guarantee

A prequalification or preapproval does not mean the mortgage has received final underwriting approval. The loan may still depend on verification of income and assets, acceptable credit, appraisal, title, insurance, property condition, and other lender requirements.

That is why a seller should review the complete offer, including:

• Financing and appraisal contingencies
• Earnest money
• Down payment
• Requested seller concessions
• Proposed closing date
• The buyer’s available funds
• Deadlines for loan application and lender approval

A slightly lower offer from a well-prepared buyer may sometimes present less closing risk than a higher offer supported by incomplete or outdated financing information. That does not mean a seller should automatically choose the lower offer. It means price and probability of closing should be considered together.

What about cash offers?

For a cash offer, request current proof of funds instead of a lender letter. The documentation should reasonably support the purchase price and expected closing costs.

Sensitive account numbers should be redacted. The goal is to confirm that adequate funds appear to be available—not to collect unnecessary private financial information.

A practical seller checklist

Before accepting an offer:

1. Confirm whether the purchase is financed or cash.
2. Obtain a current prequalification, preapproval, or proof-of-funds document.
3. Check that the documented amount supports the offer.
4. Review the loan type, down payment, concessions, appraisal terms, and financing deadlines.
5. Confirm that the lender or financial institution can be contacted.
6. Compare the offer’s net proceeds and contract terms—not just its headline price.
7. Keep the financing document with the transaction records.
8. Continue monitoring financing milestones after contract acceptance.

How OfferPath helps

OfferPath gives buyers and sellers a guided way to organize an Arizona real estate offer and understand the information needed to evaluate it. Financing readiness belongs near the beginning of that process, before a seller commits to a contract.

The goal is not to eliminate every possible financing issue. No platform, agent, lender, or document can guarantee that a transaction will close. The goal is to help the seller make a more informed decision with clearer evidence of the buyer’s ability to perform.
