The 7 Biggest Deal Killers for Home Sellers Right Now (and How to Avoid Them)

You’ve accepted an offer, signed the paperwork, and started picturing your next move. Then, suddenly, things slow down or fall apart entirely. Maybe the inspection uncovers an issue or the buyer’s financing hits a snag, and you’re back at square one. It’s a frustrating reality, but even strong offers don’t always make it to the closing table.

According to the National Association of Realtors (NAR), about 6% of contracts don’t make it to the finish line, and many others face delays along the way. The good news is that these setbacks often follow familiar patterns.

In this guide, we’ll break down the biggest home sale deal killers affecting sellers today and how you can avoid them.

Connect with a Top Agent to Sail Through to Closing

Working with a top agent can help you get to closing day faster — and get you more for your home sale. We analyze over 27 million transactions and thousands of reviews to determine which agent is best for you based on your needs.

Get Started

1. Your home’s sewer, roof, or furnace fails inspection

Deals often start to unravel at the home inspection stage. Problems like aging systems, deferred maintenance, or structural damage can surface late, giving buyers a reason to renegotiate or walk away. Even minor issues can raise red flags as repairs start to add up. With today’s buyers more cost-conscious and wary of taking on major work, unexpected problems can feel like a big risk.

“Sewer, roof, and furnace are the three big items that, if there are issues with them, can cause a buyer to cancel a transaction,” says Monica Graves, a Colorado real estate agent with more than three decades of experience.

For sellers, a little preparation can go a long way. A pre-listing inspection helps you catch major issues early and focus on the small fixes that offer the most value, while clear disclosures set expectations upfront. Pricing your home with its condition in mind can also help keep negotiations on track and your sale moving forward.

2. Your buyer’s financing collapses

Few things are more frustrating than finding out your buyer doesn’t have the money to back their offer. Even well-qualified buyers can run into trouble once underwriting begins. A job change, new debt, or missing documentation can delay approval or stop it altogether.

Graves says rising ownership costs are playing a bigger role. “It’s causing buyers to actually have to terminate the loan because the payment ends up being too high,” she explains, pointing to increases in insurance, taxes, and HOA fees.

To protect yourself, look for buyers who are fully vetted or pre-underwritten, not just pre-approved. It also helps to pay attention to the lender involved and how clearly they communicate throughout the process. Offers from buyers who are stretching their budget may carry more risk, so a slightly lower but stronger offer can sometimes be the safer choice.

3. Your buyer’s own home sale falls through

Some offers come with conditions that can put your deal at risk. These are known as contingencies, meaning the sale depends on certain requirements being met before closing. Buyers often include an inspection or financing contingency to protect against the first two deal killers above.

In the current tepid market, one of the most common safety-net clauses used by buyers is the home sale contingency, meaning that, to purchase your house, the buyer must first sell their own home. Until this condition is satisfied, the deal isn’t final and can still fall through.

To reduce risk, sellers may want to prioritize offers with fewer contingencies or negotiate shorter timelines when possible.

If you do accept a contingent offer, keep the lines of communication wide open. As Graves puts it, “Communication is very important between all the agents involved in those contingencies because we need to know how things are going in terms of the deadlines.”

It can also help to continue marketing your home or keep a backup offer in place. In some cases, sellers add a kick-out clause, allowing you to move on to another offer if the buyer can’t remove their contingency in time.

4. Your home’s appraisal comes in low

An appraisal can quickly change the direction of a deal. If your home comes in below the agreed-upon price, lenders typically won’t cover the gap, leaving buyers to make up the difference in cash or renegotiate. If buyers don’t have the funds, the deal can hit a dead end.

While this feels daunting, there are steps you can take to keep your sale on track.

“The seller agent can negotiate and maybe meet in the middle somewhere with the price,” says Graves. This way, “the seller doesn’t have to take the entire hit on the purchase price.” If the buyer won’t agree to split the difference, she says sellers can revisit concessions they’ve already offered, such as closing cost help or repair credits, and adjust the price accordingly.

To lower your risk of appraisal gaps from the start, price your home based on recent, realistic comparable sales. A skilled agent can help select the right comparables and position your home in line with how appraisers assess value. It also helps to ask buyers upfront if they can cover a potential gap.

5. Your title search reveals an unpleasant surprise

Some deal problems don’t show up until the final stages. Title issues, such as unpaid taxes, old liens, boundary disputes, or unclear ownership, can surface during escrow and put everything on hold. Many sellers don’t realize these problems exist until a title search reveals them, but they need to be resolved before closing.

Graves notes that situations like probate or title name discrepancies can also cause delays. Sellers can usually fix these issues, but this can take extra time and coordination.

To avoid surprises, it helps to run a preliminary title report early in the process. This gives you time to resolve any problems before you’re under contract. Working with an experienced agent and title company can also make a big difference, helping you clear issues quickly and keep your sale on schedule.

6. Your buyer gets cold feet, chilled by uncertainty

Not every deal falls apart because of an obvious issue. Sometimes buyers simply get nervous or change their minds. With ongoing concerns about interest rates, affordability, and overall economic uncertainty, some buyers feel less confident about the future. Some contracts also include clauses that give buyers a window to back out, which can make it easier for second thoughts to turn into canceled deals.

To keep buyers committed, sellers can focus on maintaining momentum. Clear timelines, quick responses, and steady communication can help keep everyone on track. A smooth, low-stress experience from contract to closing can reduce second-guessing.

It’s also smart to have a backup plan. Continue marketing your home, line up a backup offer, or consider a cash offer so you have options if a buyer decides not to move forward.

7. Miscommunications, mistakes, and mix-ups

Even solid deals can fall apart when communication breaks down. With agents, lenders, buyers, and sellers all involved, it doesn’t take much for wires to get crossed. A missed deadline, a delayed response, or unclear expectations can quickly create confusion.

Today’s transactions move fast, leaving little room for mistakes or mix-ups. When people aren’t on the same page, small issues can quickly turn into deal-breaking ones.

Graves says she often sees this happen when conversations rely too heavily on texting. “Texts are important, but when it is a negotiation type of thing that happens between the buyer agent and the listing agent, or between the buyer and the seller, I think that phone call communication is better than text communication. It’s really hard to negotiate with a text or with an email.”

Sellers can keep things running smoothly by working with experienced, responsive professionals. Set clear expectations from the start, confirm important deadlines, and stay in regular contact so nothing falls behind.

How sellers can protect their deal from day one

The truth is, most home sale deal killers aren’t random. They’re predictable and, with the right approach, often preventable. Sellers who take a proactive approach from the start are more likely to avoid the biggest pitfalls and keep their deal intact.

Here are a few ways to set yourself up for a smoother sale:

• Work with a top agent: An experienced agent can guide pricing, vet offers, and flag potential red flags before they become problems. HomeLight’s Agent Match can connect you with top-performing agents in your area.
• Look beyond the offer price: A strong offer isn’t just about numbers. Pay attention to contingencies, financing strength, and the buyer’s overall position.
• Prepare your home and paperwork: Pre-listing inspections, clear disclosures, and early title work can prevent surprises later in the process.
• Stay organized and responsive: Keep a close eye on deadlines, respond quickly to requests, and make sure all parties stay aligned.

It can also help to understand your options if a deal falls through. Some sellers keep their home on the market or consider working with vetted cash buyers, which can reduce delays tied to financing and contingencies.

For even greater certainty, many homeowners who are buying and selling are turning to buy-before-you-sell programs. These modern solutions unlock existing equity, allowing you to make a stronger, non-contingent offer on your new home and only move once.

With the right preparation and expert guidance, you can approach your sale with more confidence and avoid these seven home sale deal killers.
