Most real estate deals don’t fall apart because of the home itself. They fall apart quietly in underwriting. For many Realtors, this stage can feel like a black box where decisions are made behind the scenes. The truth is, underwriting follows very specific rules, and when you understand the red flags, you can spot problems early and guide your clients more effectively.
If you want to close more deals, reduce stress, and build trust with your buyers and sellers, understanding these underwriting red flags is essential.
What Is Underwriting and Why It Matters
Underwriting is the process where a lender verifies every part of a borrower’s financial profile. Income, assets, credit, and the property itself are all reviewed in detail. While a pre approval gives a buyer confidence, underwriting is where the deal is truly approved or denied.
For Realtors, this is the stage where proactive communication and early awareness can make or break a transaction.
1. Inconsistent Income
One of the most common red flags is income that is difficult to verify or unstable. This includes commission based earnings, bonuses, overtime, or side income.
Underwriters typically look for a two year history of consistent income. If a buyer recently started earning more but does not have a track record, that income may not fully count.
As a Realtor, it helps to ask early questions about how your client earns money. If their income is complex, encourage them to work closely with a lender before making offers.
2. Large Unexplained Deposits
Buyers are often surprised to learn that every large deposit in their bank account will be reviewed. Whether it is a gift, a transfer, or cash, it must be documented.
If the source of funds cannot be verified, the lender may exclude that money from the transaction. In some cases, it can delay or even stop the deal entirely.
You can prevent this by having a simple conversation with your buyer early on. Ask where their down payment and closing costs are coming from and remind them to keep documentation.
3. Employment Changes During the Process
A job change might seem like a positive move, especially if it comes with higher pay. However, underwriting focuses on stability more than potential.
Switching from a salaried position to commission or self employment can create complications. Even moving to a new company in the same field may require additional documentation.
Setting expectations upfront is key. Let your buyers know that staying in their current role until after closing is one of the safest ways to protect their purchase.
4. New Credit Activity During Escrow
This is one of the most preventable issues, yet it happens all the time. Buyers open new credit cards, finance furniture, or take out auto loans while under contract.
Even small changes can impact debt to income ratios. A deal that was approved at the beginning can quickly fall apart if new obligations are added.
Make this part of your standard buyer education. Remind clients that their financial picture must remain stable from contract to closing.
5. Property Condition Issues
Underwriting is not only about the borrower. The property must also meet certain standards. Lenders want to ensure the home is safe, livable, and marketable.
Issues like roof damage, peeling paint, structural concerns, or safety hazards can trigger repair requirements. In some cases, the loan cannot move forward until those issues are resolved.
When walking a property, try to view it through the lens of an underwriter. This mindset can help you anticipate problems before they show up in the appraisal.
6. High Debt to Income Ratio
Debt to income ratio is one of the most important factors in underwriting. It measures how much of a borrower’s income is already committed to debt payments.
When a buyer is close to the maximum allowable ratio, there is very little room for change. Adjustments in taxes, insurance, or interest rates can push the deal over the limit.
Strong Realtors build in margin. Encouraging buyers to stay slightly below their maximum approval can protect the deal from unexpected changes.
7. Final Verification Issues
Many Realtors assume that once a loan is approved, the deal is done. In reality, lenders perform final checks right before closing.
They may re verify employment, pull credit again, and confirm assets. If anything has changed, the loan can still be delayed or denied.
This is why communication matters all the way through closing. Keeping your client informed and engaged until the transaction is funded is critical.
How Realtors Can Stay Ahead of These Red Flags
The best way to avoid underwriting surprises is to stay proactive. Ask better questions early, partner with experienced lenders, and educate your clients on what to expect.
Simple habits can make a big difference. Encourage transparency from buyers, maintain regular communication with the loan officer, and set clear expectations about financial behavior during the transaction.
Understanding underwriting red flags is one of the most valuable skills a Realtor can develop. It allows you to anticipate issues, guide your clients with confidence, and protect your deals from unnecessary risk.
When you can spot problems before they happen, you do more than close transactions. You position yourself as a trusted expert who truly understands the full path to closing.
