Three Sources of Information for Shop-and-Upper Investors: Commercial Surveyors, Empty Homes Officers and Post-Auction Lots

Draft, pending publication confirmation

Main points

Commercial surveyors provide building-level evidence and cost information.
Empty homes officers provide context about residential vacancy and owner pressure, but cannot provide confidential property or owner lists.
Post-auction unsold lots provide evidence of what the market did not accept at the reserve.
The three channels should operate as a funnel: auction evidence and vacancy data create a longlist, then professional surveying tests the shortlist.
The key question is not whether a property looks inexpensive. It is whether the price is below the cost of replicating the asset once the works are known, and whether the vendor is motivated.
Most candidates should be rejected before acquisition.
Shop and upper residential parts must be assessed separately. Their leases, voids, compliance requirements and income assumptions are different.
Realty Packaging uses four screening pillars: lease structures, planning, building condition and operational compliance.
A 7.5% gross yield and a 12% return at 75% loan-to-value with 6% interest-only finance are screening rules, not guaranteed returns.
Gross Development Value and residual land value remain hypothetical unless supported by planning, design, cost plans, finance terms and comparable evidence.

The core argument: three channels, one funnel

These sources provide different information.

Auction results and unsold lots provide evidence. They show what sold, what failed to sell, where reserves sat and how the market is pricing a street or building type.
Empty homes data provides pressure. It can show where long-term residential vacancy clusters and where owner motivation may exist.
Commercial surveyors provide cost. They assess what the building needs and help convert defects into a financial number.

The sequence matters. Realty Packaging can build a desk-based longlist from auction evidence and published vacancy data. A professional surveyor can then assess shortlisted assets before an investor decides whether the price reflects value or merely reflects the problem.

The cheapest stage of due diligence is the stage that tells an investor not to proceed.

These channels are information sources, not acquisition strategies. None removes the need for legal, planning, financial and technical verification. None provides confidential owner information. Any claim to the contrary should be treated with caution.

Channel one: commercial surveyors

Commercial surveyors are often inside a building before other professional parties. They are therefore a direct source of building-level information.

The reason for a pricing gap usually sits in the building itself. Examples include:

Structural movement.
A roof approaching the end of its serviceable life.
Wet rot behind a shopfront.
Drainage defects.
Party wall issues.
Defective electrical, heating or ventilation installations.
Fire separation problems between the commercial and residential parts.

A surveyor does more than identify a defect. The surveyor can help cost the problem through a schedule of condition, dilapidations assessment, EPC and MEES review, extraction assessment, or fire-separation review.

Professional standing also matters. RICS-regulated work, professional indemnity insurance and a written scope of duty can produce evidence that withstands scrutiny. RICS professional standards and dilapidations guidance provide a useful framework for relevant instructions.

Surveyors may see stock early through:

Refurbishment and conversion instructions.
Lender and receivership work.
Probate and estate work.
Owners seeking a clean exit.
Building inspections connected with lease events.

There are limits. A surveyor may not disclose owner details. There may be a conflict where the surveyor is already instructed on a property. Local knowledge is also relationship-based and may not transfer between areas.

A surveyor can explain what is wrong with a building. A surveyor cannot decide whether it is a good investment. That judgement belongs to the investor and to Realty Packaging’s Four Pillars review.

Channel two: empty homes officers

An empty homes officer works for a local authority. The role is to help return long-term empty, privately owned homes to use. The objective is the council’s housing need, not an investor’s property pipeline.

An officer may:

Investigate empty residential property.
Contact and negotiate with owners.
Offer advice about sale, letting or refurbishment.
Explain available grants or loans where the council operates a relevant scheme.
Escalate persistent cases towards enforcement.

Possible enforcement tools include Empty Dwelling Management Orders, enforced sale and, in serious cases, compulsory purchase. These tools are used sparingly. They are not a route for investors to acquire property at a reduced price.

Empty homes officers cannot supply a list of properties or owner details. Data protection and impartiality prevent that. Anyone selling “empty homes officer leads” as a product may be misrepresenting the role.

The useful information is more general. Published council empty homes strategies, housing reports and committee papers may show:

Areas with persistent residential vacancy.
The scale and character of the local problem.
The council’s approach to engagement and enforcement.
Whether long-term empty homes are concentrated in particular streets or parades.

Council tax premiums can also indicate pressure. In England, councils may apply premiums of up to 100% for homes empty for one to five years, 200% for five to ten years and 300% for more than ten years. These are discretionary. Notice requirements, exceptions and local application must be checked with the billing authority. See the GOV.UK guidance on long-term empty homes and council tax premiums.

A long-term empty home may indicate owner motivation. It may also indicate a title defect, probate issue, absent or deceased owner, structural problem or leasehold dispute. Distress does not automatically mean a reduced transaction price.

The scope is also important. Empty homes legislation concerns residential property. A vacant commercial shop is not an empty home. For shop-and-upper buildings, this channel is mainly relevant to vacant or derelict residential upper parts.

Channel three: post-auction unsold lots

An unsold lot is a property that has not sold, often because the reserve was not met. It may remain available for approach through the auctioneer, subject to the vendor’s instructions.

The main benefit is price discovery. An unsold lot shows what the market did not accept at the auction. That is evidence which an asking price cannot provide. It can help calibrate views of value for a street or building type.

The eventual transaction may still proceed on auction terms, using the same legal pack and a short completion timetable. The buyer may therefore take on auction risk without the competitive pressure of the room.

Risks include:

Caveat emptor: the buyer must investigate the asset before committing.
Legal packs are prepared by the seller’s solicitor. There is no universal rule requiring every relevant issue to be included.
A solicitor must review restrictive covenants, overage provisions, rights of way, service charge liabilities and tenancies.
Vacant possession must be confirmed rather than assumed.
In a modern method of auction, a buyer may pay a non-refundable reservation fee for an exclusivity period, often around 56 days. Formats differ, so the commitment point and applicable terms must be confirmed for each lot.
Finance must be arranged and verified before an auction commitment. An unconfirmed mortgage offer is a material risk.

How the three channels combine

The funnel should operate as follows:

Review auction results and unsold lots for market evidence.
Review council strategies, reports and committee papers for residential vacancy patterns.
Build a longlist without assuming availability, owner motivation or value.
Reject assets with obvious legal, planning, operational or financial problems.
Instruct a commercial surveyor on the shortlist.
Obtain a solicitor’s review of the title and legal pack.
Cost the works before deciding whether the price is below the cost of replication.

The objective is to identify an asset where the price sits below the cost of replicating the asset once the works are known, and where the vendor has a reason to transact. It is not to identify an asset that merely looks inexpensive on a property portal.

Screening: the Four Pillars and thresholds

Realty Packaging reviews opportunities through four pillars.

1. Lease structures

Check the existing lease, or the lease to be granted:

Term, reviews and breaks.
Repairing and insurance obligations.
Security of tenure under the Landlord and Tenant Act 1954.
Guarantees and rent deposit provisions.
Separate upper residential tenancy arrangements.

2. Planning

Check lawful use, conditions, operating hours, extraction and odour requirements, advertisement consent, Article 4 Directions and any conversion consent. The Town and Country Planning (Use Classes) Order 1987 is a relevant reference, noting that the original 1987 classes have since been amended and that the current Class E and Class F classes should be checked in the revised version. Planning potential is not planning consent and does not override restrictive covenants.

3. Building condition

Review the roof, structure, damp, drainage, party walls, floor loading, ceiling heights, services, and fire separation between the commercial and residential parts.

4. Operational compliance

Assess EPC and MEES separately for the commercial and residential elements. Also check fire safety, means of escape, electrical and gas safety, ventilation, waste, grease management, licensing, accessibility, insurance, business rates and council tax.

For privately rented homes, the direction of travel is an EPC C-equivalent standard by 2030. This is not the same as a Band B requirement. Empty buildings may also face stricter unoccupied-property insurance conditions and higher premiums.

Realty Packaging’s screening rules are:

7.5% gross yield.
12% return at 75% LTV using 6% interest-only finance.

The arithmetic is: four times the gross yield, less 18% for 75% of 6% finance. A 7.5% gross yield therefore produces approximately 12% on the deposit before costs. There is no headroom at exactly 7.5%.

This is a screening rule, not a guaranteed return. A vacant or derelict building cannot be screened on assumed rent. Gross yield must use evidenced tenant rent payments, with voids and works reflected in the return.

Financial assumptions table

The following is a generic illustration. It is not a model of any property and cannot establish viability.

Item	Annual	Monthly	Illustration
Acquisition price	£400,000	-	Assumed price
25% deposit	£100,000	-	Capital contribution
75% mortgage	£300,000	-	Assumed loan
Interest-only finance at 6%	£18,000	£1,500	Subject to lender terms
Non-residential SDLT	£9,500	-	£0 on first £150,000; £2,000 on next £100,000; £7,500 on remaining £150,000
Legal and survey allowance	£4,000	-	Early allowance only
Refurbishment allowance	£60,000–£100,000	-	Requires contractor and quantity surveyor cost plan
Capital employed before works	£113,500	-	Deposit, SDLT, legal and survey only

The SDLT treatment, property classification and all other inputs require tax and professional verification.

GDV and value-add

Potential value-add may involve lease strengthening, rent reviews, upper-floor residential value, planning, refurbishment, EPC improvements or refinancing.

Each assumption must be separated from verified facts. A rent review does not guarantee an increase. Upper residential value must be modelled separately from the commercial shop and not blended into one yield. The two parts have different rules, voids and compliance requirements.

Refurbishment and EPC works should be costed through contractor and quantity surveyor plans. Refinancing after stabilisation depends on lender valuation, interest cover, finance terms and the lender’s view of the security.

For the generic illustration, arithmetic at a 7.5% yield implies approximately £533,333, while arithmetic at an 8% yield implies approximately £500,000. These are hypothetical capitalisation calculations, not valuations.

GDV and residual land value are hypothetical unless supported by planning, design, cost plans, finance terms and comparable evidence. GDV is not market value, investment value or loan value.

Structures, capital allowances and tax strategy

A limited company is a separate legal entity. An LLP generally passes taxable profits to its members under its agreement. Finance, profit extraction, liability, reporting and tax treatment differ between structures.

Capital allowances may apply to qualifying fixtures and integral features in commercial property. The available treatment depends on the asset, transaction documents, previous claims and any required elections. Residential parts are treated separately.

Tax-advantaged property investment strategies may involve capital allowances, qualifying reliefs or an investor-specific structure. No structure creates an automatic tax advantage. Investors should obtain independent tax advice before acquisition.

Risks, limits and verification checklist

Before committing, verify:

Whether an auction lot is genuinely unsold rather than withdrawn.
The full legal pack and special conditions with a solicitor.
Title, covenants, overage, rights of way and service charge liabilities.
Whether vacant possession is deliverable.
Building condition through a survey and cost plan.
Finance before any auction commitment.
EPC requirements for each element separately.
Business rates and empty property relief.
Council tax and premium position with the billing authority.
Planning, lawful use and any enforcement action.
Cost overruns, delays, voids and interest rate movement.

Residential lettings must also be assessed against the Renters’ Rights Act 2025 and current requirements.
