Hugo D. Selling a commercial property isn’t like selling a house. The stakes are higher, the process is more complex, and a single mistake can cost thousands—or even derail the entire deal. Yet, many sellers make the same avoidable errors, often without realising the impact until it’s too late.
If you’re preparing to sell, knowing what not to do is just as important as knowing what to do. Let’s go through the biggest mistakes sellers make and how to avoid them.

Undervaluing a Quality Commercial Estate Agent
It’s tempting to think all estate agents are the same. They put up a listing, arrange viewings, and negotiate offers—how different can they really be? The reality is, the right commercial estate agent can make or break your sale.
If you’re looking to sell commercial property, choosing an agent with experience in the sector is essential. Unlike residential sales, commercial properties vary drastically in size, use, and investment potential. A good agent recognises this and tailors their approach accordingly. They don’t just stick a price tag on it and hope for the best. Instead, they understand that selling a fully tenanted office building requires a completely different strategy from selling a vacant warehouse.
A skilled agent will:
- Identify the right buyers – Investors, developers, and business owners all have different motivations, and marketing should reflect this.
- Position the property correctly – Highlighting aspects like rental yield, potential redevelopment opportunities, or existing long-term leases can attract serious buyers.
- Negotiate effectively – Commercial buyers are often experienced and strategic. You need an agent who knows how to navigate complex deals without leaving money on the table.
Trying to cut costs by working with a generalist—or worse, attempting to sell without professional support—can lead to undervaluation, long delays, or an outright failure to sell.
Setting the Wrong Asking Price
Pricing is one of the most challenging aspects of selling a commercial property. Get it wrong, and you risk either scaring off buyers or losing out on potential profits.
Many sellers fall into the trap of overpricing. They set their figure based on what they want to make, not what the market will actually pay. The problem? A property that sits on the market too long quickly becomes unattractive. Buyers start asking, “What’s wrong with it?” and assume there’s a hidden issue. Eventually, the seller is forced to drop the price—sometimes multiple times—until it finally moves, often for much less than they originally hoped.
On the other hand, underpricing means leaving money on the table. Some sellers, eager for a quick sale, accept the first reasonable offer without realising they could have achieved more with a better marketing strategy.
The best approach? Let market data guide the price. Comparable sales, current demand, rental income potential, and development opportunities should all be factored in. A strong agent will help with this, ensuring the price is attractive to buyers without underselling the asset.
Poor Presentation and Neglecting Maintenance
You wouldn’t try to sell a house with peeling paint and broken fixtures—so why do so many commercial sellers think it doesn’t matter? First impressions count, and a neglected property instantly puts off serious buyers.
Even investors looking for a project want to see potential, not problems. A property that looks uncared for raises red flags about deeper issues, like structural integrity, plumbing, or electrical systems.
Presentation matters whether the property is tenanted or vacant. A well-maintained, visually appealing building not only attracts more interest but can also justify a higher asking price. Simple improvements—fresh paint, clean communal areas, tidy landscaping—can make a huge difference. If the space is empty, consider light staging to help buyers visualise how it could be used.
Ignoring Key Documentation
Selling a commercial property involves far more paperwork than a residential sale. If your documents aren’t in order, expect delays, complications, and even lost deals.
Buyers will want to see:
- Title deeds and property records – Proof of ownership and any encumbrances.
- Lease agreements (if applicable) – A clear picture of tenancy terms, rental income, and potential risks.
- Planning permissions and zoning details – Ensuring the property aligns with the buyer’s intended use.
- Service charge breakdowns and maintenance history – Especially relevant for multi-unit buildings or properties with shared spaces.
Any missing, outdated, or unclear documents can create uncertainty and cause buyers to hesitate. The solution? Get everything organised before listing the property. Having a solicitor or professional advisor review your paperwork early can save time and prevent last-minute surprises.
Overlooking Tax Considerations
Taxes can be a significant factor in commercial property sales, yet many sellers only think about them when it’s too late. Capital gains tax, VAT, and stamp duty all come into play, and miscalculations can eat into your final profits.
For instance, some commercial properties are VAT-exempt, while others are subject to VAT at the point of sale. If the buyer wasn’t expecting this, it can complicate financing and even cause the deal to fall through. Similarly, capital gains tax obligations can be substantial, especially if the property has appreciated in value.
Speaking with a tax professional early on can help you structure the sale in the most tax-efficient way. In some cases, there may be legal strategies to reduce liabilities, but you need to plan ahead—not scramble at the last minute.
Focusing Only on Traditional Marketing
Listing the property on a few websites and waiting for offers isn’t enough. Commercial real estate buyers don’t always browse listings like homebuyers do. Many of the best deals happen through industry connections, direct outreach, and targeted marketing strategies.
A strong marketing plan should include:
- Engaging digital campaigns – High-quality photos, virtual tours, and even video walkthroughs can help showcase the property effectively.
- Targeted networking – Reaching out to known investors, business owners, and developers who may be interested.
- Off-market opportunities – Some properties sell better through discreet negotiations rather than public listings.
If your agent isn’t actively marketing the property beyond a standard listing, you’re missing out on potential buyers who aren’t scrolling through property portals every day.
Underestimating Buyer Due Diligence
Serious buyers don’t just take a quick look and make an offer. They conduct thorough due diligence, and if they find anything unexpected, the deal can stall—or collapse entirely.
Buyers will scrutinise everything from structural reports to lease agreements, environmental assessments, and local planning regulations. If they uncover hidden issues, they might demand a price reduction or walk away altogether.
The best approach? Anticipate their questions and concerns in advance. A well-prepared seller proactively addresses potential red flags and provides clear, transparent information upfront. This builds confidence and speeds up the negotiation process.
Selling Smart: How to Get It Right
Selling a commercial property isn’t just about listing it and waiting for offers. It’s about strategy, preparation, and knowing how to position your property for the best possible outcome.
By avoiding common mistakes—choosing the right estate agent, setting a competitive price, presenting the property well, and ensuring your paperwork is airtight—you increase your chances of a faster sale and a higher final price.
If you’re thinking about selling, take the time to plan properly. Because in commercial real estate, the right approach doesn’t just make a difference—it makes thousands of pounds’ worth of difference.
