My buyer is a first-time buyer. Is that risky?

The worry is understandable. A first-time buyer feels less proven than someone who has sold and bought before, and the phrase itself sounds like inexperience. The evidence points the other way for most of what actually breaks a sale.

What is a first-time buyer, exactly?

A first-time buyer is someone purchasing a home who has never owned one before. They have no property to sell, so there is nothing behind them in the chain. A chain is the line of linked sales where each purchase depends on the one before it completing.

That single fact removes the most common way a sale dies. It does not remove every risk, and pretending otherwise would not help you.

Is a first-time buyer safer than a buyer in a chain?

On the evidence, yes, on the risks that matter most. Around one in four agreed UK sales collapsed before completion in the first quarter of 2026, at a national fall-through rate of 23.7%. Broken chains and buyers withdrawing are two of the biggest causes, and a chain-free buyer is exposed to neither in the same way.

So what should I actually worry about?

The deposit and the lender. A first-time buyer's deposit is a fixed sum they have saved or been given, so it cannot stretch. In December 2025, 44% of first-time buyers took mortgages at 85% to 90% loan-to-value, up from 41% a year earlier, and 22% bought with deposits under £20,000, up from 13%.

Loan-to-value is the size of the mortgage as a percentage of the property's value. The higher it is, the less room there is if the lender's valuation comes in below the agreed price, because the buyer has to find the difference in cash.

Timing matters too. The average mortgage rate paid rose from 4.65% in June to 4.75% in July 2026, and increases since January have added around £125 a month to a typical mortgage. A buyer working from an agreement in principle issued early in the year may be quoting a budget that no longer exists.

What questions should I ask before I accept?

1. How much is the deposit, and is it already in their account? A gifted deposit that has not yet been transferred is a plan, not a deposit.
2. When was the agreement in principle issued, and at what rate? Anything more than a few months old deserves a refresh before you take the house off the market.
3. Which lender, and has a full application been submitted? An agreement in principle is a soft indication; a submitted application is real movement.
4. Have they instructed a solicitor and paid anything on account? Money spent is the honest measure of commitment.
5. Is anyone helping with the deposit, and have they confirmed it in writing? Lenders will ask; you may as well know first.

Read a buyer by what they have spent and instructed, not by what they have said.

How do I protect myself while the sale goes through?

The asymmetry to watch is simple. Sellers tend to commit money early, instructing solicitors, paying for information packs and coming off the market, while a buyer who has spent nothing can still change their mind at no cost.

• Line up your own solicitor early. It is cheap, it keeps momentum, and it costs you little if things stall.
• Hold the larger, irreversible spends until the buyer's mortgage application is in and their survey is booked.
• Treat a booked and paid-for survey as the first real signal. Around 38% of collapsed sales fail within the first four weeks of being agreed, so the early weeks are where attention pays.
• Agree with your agent what happens if the lender's valuation comes in low, before it happens rather than after.

The short answer

A first-time buyer is not a weak buyer. They are a different shape of buyer, with less chain risk and more affordability risk, and both are things you can check before you say yes.

ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents. Seeing several agents' views before you list means you set a price the market can actually reach, which is the best protection against a down valuation later. The choice of agent, the price and the timing stay with you.
