A plain-English guide to screening commercial property deals before capital is committed.
Why Due Diligence Matters More Than the Headline Yield
A commercial property deal can look attractive on the first page. The yield looks strong. The tenant looks stable. The valuation seems sensible. The broker says there is interest from other buyers. For time-poor professionals, that is exactly where the risk begins.
The problem is not usually the property itself. The problem is what has not yet been tested. Commercial property is an income-producing asset. The rent, the lease, the tenant, the building condition, the borrowing position, the pension structure and the exit route all have to work together. If one part is weak, the whole deal can become harder to finance, harder to refinance and harder to sell.
This is why due diligence cannot be treated as a legal formality at the end of the process. It has to shape the decision from the start. The best question is not, “Can we buy this asset?” The better question is, “Should this asset enter a pension portfolio at all?”
Start With the Job the Asset Must Do
Before reviewing a lease or speaking to a lender, the investor needs to define the role of the property. Is the asset intended to create stable income? Is it intended to release capital through refinance? Is it being bought inside a SSAS or SIPP? Is it a first asset, or part of a wider commercial property pension strategy?
The answer changes the due diligence standard. A property bought for long-term pension income needs durable tenant demand, a lease that supports predictable rent, and a building that will not absorb cash through avoidable repairs. A value-add deal needs evidence that income can increase and that a lender will recognise the new value once the work is complete.
Without this first filter, investors compare deals only by yield. That is too narrow. A 9% yield with a weak lease, poor EPC position and uncertain refinance route can be inferior to a 7% yield with stronger tenant security and a clearer exit.
Tenant and Income Verification
The tenant is the engine of the investment. The first commercial question is simple: can the tenant keep paying rent, and will the income still be attractive to the market when the property is refinanced or sold?
A serious review should check the tenant’s trading history, accounts, payment record, sector exposure and need for the premises. A national tenant is not automatically safe. A local tenant is not automatically weak. What matters is covenant strength, operational relevance and evidence of rent affordability.
The rent also needs to be tested against market evidence. If the rent is above market level, the current yield may be misleading. A valuer may discount it. A lender may haircut the income. A future buyer may price in the risk of rent reduction at review or renewal. If the rent is below market level, there may be a genuine value-add opportunity, but only if the lease allows it and the tenant can sustain the higher rent.
Lease Review: The Document That Controls the Value
In commercial property, the lease is not paperwork. It is the income contract. It controls rent, term, break rights, repair obligations, alienation, rent review, insurance, use, alterations and default remedies.
Investors should focus on the clauses that directly affect value. The unexpired lease term matters because lenders and buyers price certainty. Break clauses matter because they can shorten income security. Repair obligations matter because a full repairing and insuring lease can shift major costs to the tenant, while a weaker lease can leave the landlord exposed.
Assignment and underletting clauses matter because they affect tenant flexibility and landlord control.
Rent review wording also deserves close attention. Upward-only reviews, index-linked reviews and open-market reviews create different risk profiles. A lease that looks attractive today may become less attractive if the review mechanism caps future growth or creates a dispute risk.
A clean due diligence process should produce a plain-English lease summary before exchange. It should not wait until the solicitor’s report arrives in technical language that the investor has no time to interpret.
Building Condition, EPC and Compliance
A strong tenant cannot rescue a poor building if the asset requires immediate capital expenditure. The physical survey should identify roof issues, structural movement, damp, services condition, fire safety concerns, access limitations and any defects that could affect occupation.
Energy performance has become a core investment issue. Non-domestic landlords in England and Wales generally need at least an EPC E rating for privately rented property unless a valid exemption applies. A low EPC rating can affect lettability, future capex and buyer appetite. It should be reviewed before the price is agreed, not after completion.
Asbestos also needs specific attention, especially in older commercial buildings. The dutyholder must check responsibility under the lease, identify where asbestos is present, keep records, assess risk and share information with people who may disturb it. This is not an optional box-ticking exercise. It is a legal and operational risk.
The due diligence question is practical: what will this building cost to keep compliant, lettable and financeable over the next five to ten years?
Finance Due Diligence Before Exchange
Many investors make the mistake of treating finance as a post-offer task. That weakens the deal. The finance strategy should be tested before exchange because the lender’s view determines how much capital must remain in the asset.
The review should cover loan-to-value, interest cover, debt service, arrangement fees, valuation assumptions, personal guarantees, repayment structure and refinance options. For pension-owned property, borrowing limits also matter. HMRC guidance states that a registered pension scheme may borrow up to 50% of the net fund value before the borrowing takes place.
A deal that needs 65% external leverage outside a pension may not work the same way inside a pension wrapper. The structure has to match the vehicle. If the asset is being bought through a SSAS or SIPP, the borrowing and cash reserve position must be checked early.
Tax and Pension Structure Review
Commercial property can be tax-efficient, but only if the structure is designed correctly. Income and gains from most pension scheme investments are generally not taxable within the pension. That is one reason SSAS and SIPP structures can be attractive for commercial property.
However, the tax position should never be assumed. VAT, capital allowances, stamp duty land tax, pension rules, connected-party issues and lease structure can all affect the result. Capital allowances in particular need specialist review. They can improve the economics of some commercial property acquisitions, but the ability to benefit depends on the buyer, the structure and the specific fixtures within the building.
The correct question is not, “Is commercial property tax-efficient?” The correct question is, “Is this specific acquisition tax-efficient for this specific investor using this specific structure?”
Exit Due Diligence: Know the Route Out Before You Buy
A pension strategy built around commercial property needs an exit plan before the first pound is committed. That exit may be long-term hold, sale, refinance or asset reconfiguration. Each route requires evidence.
If the goal is refinance, the post-value-add valuation must be credible. If the goal is sale, the buyer pool must be clear. If the goal is long-term income, the lease and tenant demand must support that plan. If the goal is capital recycling, the timing and lender appetite must be tested.
The best deals are not simply sourced. They are pre-verified. The numbers are checked, the weak points are priced, and the exit is planned before exchange.
How We Approach the Process
Our role is to protect clients from spending time on the wrong deals. We screen the asset, the tenant, the lease, the building, the finance route and the pension structure before a client commits. We bring in specialist input where needed, including commercial finance, capital allowances, legal review and pension structure advice.
The goal is not to make every deal work. The goal is to reject weak deals early and progress only the opportunities that can support a serious retirement income strategy.
For busy professionals, this matters. You do not need to become a commercial property expert. You need a process that behaves like one.
