The 7 biggest worries when buying and selling a house (and how to take the stress out of each one)

Moving home is regularly ranked among the most stressful things people go through, up there with changing job or going through a divorce. A big part of that stress is not the move itself but the worry that comes before it. Will the sale go through? Am I getting a fair price? How long is this going to drag on?

Almost a third of agreed property sales in the UK fall through before completion, so those worries are not irrational. They are the natural response to a process where so much feels outside your control.

The good news is that most of these fears come down to three things: uncertainty, cost, and trust. Once you understand what is driving each worry, it becomes far easier to manage. Here are the seven that come up most often, and what you can do about each one.

1. The sale falling through

This is the worry that tops almost everyone's list, and for good reason. Most fall-throughs happen because of a broken chain, a buyer who pulls out, or finance that does not come through. After weeks of effort, you are back to square one and often out of pocket on legal and survey fees.

What helps: ask about your buyer's position early. A buyer with no chain and funds already in place is far less likely to disappear. The fewer links in the chain, the fewer points where it can break.

2. Getting a fair price

Sellers worry about being undervalued and talked down. Buyers worry about overpaying. Both are really the same fear: that the price does not reflect what the property is worth.

What helps: get more than one valuation and look at recent sold prices for similar homes nearby, not just asking prices. Sold prices tell you what people genuinely paid, which is a much better guide than what is currently listed.

3. How long it will take

The average sale takes several months from offer to completion, and that is when everything goes smoothly. The hardest part is the lack of a firm end date. You cannot plan your next move, book removals, or give notice with any confidence.

What helps: agree realistic timescales up front and ask everyone in the chain, including solicitors, how quickly they can act. If a guaranteed completion date matters more to you than squeezing out the last few thousand pounds, it is worth saying so early.

4. Gazumping and gazundering

Gazumping is when a seller accepts a higher offer after already agreeing to sell to you. Gazundering is when a buyer drops their offer at the last minute, knowing you are committed and short on time. Both leave the other party feeling powerless.

What helps: nothing is legally binding until contracts are exchanged, so the best protection is to move quickly to that point. Choosing a buyer or seller with a track record of following through, rather than simply the best headline figure, also lowers the risk.

5. Survey surprises and hidden defects

For buyers, the fear is paying for a home and then discovering damp, subsidence, a failing roof, or something like Japanese knotweed. For sellers, a survey that flags problems can knock the price or stall the sale entirely.

What helps: buyers should always budget for a proper survey and treat it as money well spent. Sellers are often better off being upfront about known issues, because problems that surface later cause far more damage to a deal than ones disclosed at the start.

6. The hidden costs

Estate agent fees, legal fees, an EPC, survey costs, and the running cost of a home that sits on the market for months. These add up, and they are easy to underestimate when you are focused on the headline sale price.

What helps: write down every cost before you start, not just the obvious ones. Ask agents and solicitors for their fees in writing so there are no surprises later, and factor in how much a slow sale could cost you in mortgage payments and bills.

7. Trusting who you are dealing with

Underneath everything is a simple question: can I trust these people? Is the buyer genuine and funded? Is the agent working for me or for the commission? Is this company who they say they are?

What helps: look for evidence rather than promises. Independent reviews, recognised industry memberships, and a clear track record matter far more than a polished sales pitch. Any reputable company will be happy to answer direct questions about who they are, how they are funded, and how the process works.

The one thing that makes the biggest difference

Read back through those seven worries and a pattern appears. Some of them, like a buyer's mortgage falling through or a wider market wobble, are simply outside your control. You can prepare for them, but you cannot prevent them, and accepting that is part of keeping a clear head through a move.

What you can control is who is in your corner. The single biggest difference between a smooth move and a stressful one is the relationship you have with your estate agent.

A good agent does far more than put your home on the portals. They keep you informed when things go quiet, chase the people who need chasing, and tell you the truth even when it is not what you want to hear. They price your home on evidence rather than flattery, they qualify buyers properly so you are not pinning your hopes on someone who cannot proceed, and they hold the chain together when the inevitable hiccups appear. When something does go wrong, and at some point it usually does, having someone calm and experienced managing it on your behalf is worth more than almost anything else.

So choose your agent on how they communicate, not just on the valuation they quote or the fee they charge. Ask how often you will hear from them, who your point of contact will be, and how they handle a sale that hits a bump. The answers tell you a great deal about the months ahead.

You cannot remove every worry from buying and selling a house. But with realistic expectations, questions asked early, and the right agent alongside you, you can take most of the stress out of the parts that are yours to manage, and stay calm about the rest.
