When you’re selling a home, one of the most important questions isn’t just “Does the buyer love the property?”—it’s “Can the buyer actually close?” That’s where DU comes in.

What Does DU Mean?

DU stands for Desktop Underwriter. It’s an automated underwriting system created by Fannie Mae that lenders use to evaluate a buyer’s loan application. When a lender runs DU, the system reviews the buyer’s income, credit, assets, and debt, then issues a decision such as:

  • Approve/Eligible – Buyer meets all guidelines.

  • Refer/Eligible – Needs manual review.

  • Refer/Ineligible – Buyer doesn’t meet current standards.

Think of DU as the first “green light” in the financing process—it tells us how solid the buyer is before the file ever goes to a human underwriter.

Should a Seller Request DU?

Yes—and this is where I make a difference for my sellers. A pre-approval letter is good, but a DU Approval goes further. It shows that the buyer’s lender has already run the file through the system and that the loan is not just based on “stated information.” Requesting a DU can give you peace of mind that the buyer is serious, financially stable, and more likely to close on time.

How Do You Read a DU?

While DU findings can look complicated, here are the key points I review with my clients:

  • Decision: Look for “Approve/Eligible.” That’s the strongest result.

  • Loan Type: FHA, VA, or Conventional, so you know what terms the buyer is working under.

  • Conditions: DU lists documentation the buyer must provide (pay stubs, bank statements, etc.). If the buyer fails to meet them, the approval can change.

  • Reserves: Some DU approvals require cash reserves. I check to confirm the buyer has them.

Why It Matters for Sellers

Time is money. Accepting an offer that falls apart during underwriting means wasted weeks on the market. When I represent sellers, I go beyond the surface pre-approval and confirm the buyer’s lender has run DU (or a VA’s equivalent system). This simple step can mean the difference between a smooth closing and a deal that collapses.
