How to Raise Finance for Commercial Property: Investors, Bridging Loans and Mortgage Brokers Explained

Executive overview

Raising finance for a UK commercial or mixed-use property requires more than selecting the lowest interest rate.

The appropriate structure depends on:

The asset and its planning status
Purchase price and valuation
Existing rental income
Borrower experience and financial strength
Required completion date
Loan-to-value ratio
Refurbishment or development requirements
Exit plan
Leverage and risk tolerance

Shop-and-upper properties may require a combination of senior debt, investor equity and short-term finance. The correct balance can protect cash flow and reduce refinancing risk.

This article is for general education only. It is not financial, legal or tax advice. Obtain independent advice before entering into any investment, loan, equity or security arrangement.

1. Investor and equity finance

Equity finance involves raising capital from another party in return for an ownership interest, profit share or agreed participation in the project.

Potential sources include:

Private investors
High-net-worth individuals
Angel investors
Joint-venture partners
Equity partners
Family offices
Family members, subject to appropriate documentation

Equity can fund a deposit, acquisition costs, refurbishment, planning work or development expenditure. It may also be combined with a commercial mortgage, bridge or development facility.

Advantages

No scheduled interest payment in the same way as debt
Risk is shared between the parties
May reduce the amount of secured borrowing
Can provide access to property, finance or operational experience
Investors may contribute useful professional and business networks
Can support projects that do not meet mainstream lender criteria

Disadvantages

Ownership and control may be diluted
Profits must be shared
Investors require regular reporting
Agreements can be complex
Differences may arise over budgets, timing or exit
Investors may apply pressure to sell or refinance
Personal relationships can be affected if expectations are unclear

Every equity arrangement should be documented. A shareholder or joint-venture agreement should address:

Capital contributions
Ownership percentages
Voting rights
Reserved matters
Management responsibilities
Guarantees and security
Profit distribution
Additional funding
Refinancing
Sale strategy
Default
Deadlock
Dispute resolution

Raising investment from the public is not unrestricted. Financial promotion, securities and company-law rules may apply. Obtain advice from a solicitor and, where relevant, a regulated financial promotions specialist before approaching potential investors.

Other Ways to Raise Property Finance

In addition to investor equity, commercial mortgages and bridging, investors may consider other funding sources. These routes vary in cost, speed, security and risk. They should be assessed in the context of the property, the borrower, the exit plan and the investor’s wider financial position.

This section is educational only. It is not financial, legal or tax advice. No route should be treated as a recommendation.

1. Remortgaging your own home

An investor may release equity from their home through a further advance or a remortgage and use the funds toward a commercial property deposit, acquisition costs or refurbishment.

This is secured against the investor’s home. Failure to maintain repayments could put the home at risk.

Points to review include:

Affordability under the residential lender’s assessment
Loan-to-value limits
Early repayment charges on the existing mortgage
Arrangement, valuation and legal fees
Whether the interest rate is fixed, variable or due to change
The effect on monthly household cash flow
Whether the residential lender permits the proposed investment use
Whether the existing mortgage terms restrict additional borrowing for this purpose

This is normally a personal residential mortgage decision. Investors should use an appropriately authorised mortgage adviser. It should not be treated as a general recommendation.

Illustrative example: home equity release as a funding contribution

Assume a £100,000 equity release at an assumed 6% interest-only equivalent.

Annual interest: £6,000
Monthly interest: £500

This is before fees, tax and any change to the mortgage terms.

Actual residential mortgages are often repayment rather than interest-only. The actual payment could be materially higher.

Compared against a hypothetical £500,000 mixed-use purchase, this would only represent a funding contribution toward the deposit, acquisition costs or works. It is not proof of affordability, suitability or investment return.

2. Second-charge mortgage or secured loan

A second-charge mortgage or secured loan may allow an investor to raise funds without replacing the first mortgage.

Potential advantages include:

The existing first mortgage may remain in place
It may provide faster access to capital in some cases
It can be used where changing the first mortgage is not practical

Potential disadvantages and warnings include:

Rates and fees may be higher than on a first-charge mortgage
The lender takes a second security position
Total secured borrowing increases
Default and repossession risk increase
The overall household payment burden may rise materially

Regulation depends on the borrower, the property and the purpose of the borrowing. Investors should confirm the regulatory position and obtain appropriate advice before proceeding.

3. Cash savings and retained business profits

Using cash savings or retained business profits avoids lender approval and interest costs.

Potential advantages include:

No lender underwriting
No ongoing loan interest
No external security document over the funded amount
Faster deployment if funds are already available

Potential disadvantages include:

Reduced liquidity
Pressure on emergency reserves
Loss of alternative investment return
Concentration of personal or business cash in one project

Investors should consider whether cash reserves remain adequate after completion, refurbishment and any period of underperformance.

4. Family or private loans

Funds may also come from family members or private lenders.

A written loan agreement should cover:

Interest, if any
Repayment schedule
Security
Default provisions
Ranking against other lenders
What happens if the project is delayed

Risks include:

Strain on personal relationships
Misunderstandings over timing or return
Security disputes if the project underperforms
Source-of-funds and AML checks

Informal arrangements should not be relied on where capital, security or repayment expectations are involved.

5. Vendor finance, deferred consideration and seller rollover

In some cases, a seller may defer part of the purchase price or retain an interest in the project.

This can reduce the immediate funding requirement, but terms must be negotiated carefully. Key issues include:

Deferred payment dates
Interest or profit participation
Security
Priority behind or alongside senior debt
Tax treatment
Legal documentation
Default consequences

These arrangements should not be treated as commonly available. They depend on the seller, the asset, the market context and lender consent where relevant.

6. Crowdfunding and peer-to-peer/private lending

Crowdfunding and peer-to-peer or private lending may provide access to a wider pool of capital.

Potential advantages include:

Wider capital access
Flexible structuring in some cases
Possible relevance where conventional funding is limited

Key risks include:

Platform risk
Liquidity risk
Borrower or underlying asset default risk
Limited transparency
Financial-promotion and regulatory risk

Investors should check the platform’s status and obtain independent advice where appropriate.

7. Grants and local/regeneration funding

Some grants or local funding schemes may support specific works, local regeneration activity or defined business purposes.

Important limits include:

Grants are usually restricted to specific works, areas or uses
Terms may require matching funds
Claims may only be paid after expenditure
Ongoing compliance conditions may apply

Grants are not a dependable source for ordinary acquisitions. Eligibility should be verified directly with the relevant authority.

8. Vendor partnerships and joint ventures

An investor may partner with an operator, developer or another investor who contributes cash, expertise or guarantees.

A formal agreement should cover:

Control and decision-making
Profit allocation
Funding shortfalls
Responsibility for guarantees
Reporting
Exit rights

This route may help where one party brings capital and another brings operational or development capability, but the agreement must be clear before commitment.

Comparison table

Option	Security	Repayment requirement	Speed	Main advantage	Main risk
Remortgaging your own home	Usually first-charge security over the home	Monthly mortgage payments under residential terms	Moderate	Can release larger sums at residential pricing in some cases	Home is at risk if repayments are not maintained
Second-charge mortgage or secured loan	Second charge over the home or other asset	Monthly repayments required	Moderate to fast	Can raise funds without replacing the first mortgage	Higher rates and added repossession risk
Cash savings and retained business profits	None to an external lender	No contractual repayment	Fast	No lender approval and no interest	Reduced liquidity and reserve pressure
Family or private loans	Unsecured or secured, depending on terms	Usually yes, under the agreement	Variable	Flexible if terms are agreed clearly	Relationship risk and enforcement issues
Vendor finance, deferred consideration and seller rollover	Depends on negotiated documentation and ranking	Usually yes, on agreed dates or events	Variable	Can reduce day-one cash requirement	Complex legal, tax and priority issues
Crowdfunding and peer-to-peer/private lending	Depends on structure and platform	Usually yes	Variable	Access to wider capital	Platform, default and transparency risk
Grants and local/regeneration funding	Usually none in the lending sense, but conditions may apply	Usually no loan-style repayment if conditions are met	Slow to variable	Non-debt support for eligible works	Limited eligibility and unreliable timing
Vendor partnerships and joint ventures	Contractual and possibly secured rights	Depends on the agreement	Variable	Shared capital, expertise or guarantees	Control disputes and profit-sharing conflict

Order of preference

Investors should normally assess retained cash and conventional long-term debt first.

Equity may be appropriate where risk sharing, specialist expertise or a funding gap justifies it.

Home remortgaging, second charges or bridging should generally only be considered after stress testing, affordability review and independent advice.

No route is universally best.

2. Commercial mortgages and broker-arranged loans

A commercial mortgage is generally used to purchase or refinance commercial property over a longer period. A semi-commercial or mixed-use mortgage may be more appropriate where the asset includes a shop and residential upper floors.

Buy-to-let or residential finance should only be used where the property, tenancy, borrower and proposed use genuinely meet the lender’s criteria. The legal and regulatory treatment can differ depending on the property and borrower.

Key terms to review include:

Fixed or variable interest rate
Repayment or interest-only structure
Loan-to-value ratio
Mortgage term
Covenants
Rental-income coverage
Valuation basis
Personal guarantees
Arrangement and exit fees
Early repayment charges

Advantages

Suitable for longer-term ownership
May cost less than bridging finance
Can provide a predictable repayment structure
Allows the borrower to retain ownership
Can match debt payments to stabilised rental income

Disadvantages

Underwriting may take longer
A larger deposit may be required
The lender may rely on a lower valuation than the purchase price
Covenants can restrict future decisions
Valuation, legal and arrangement fees apply
Personal guarantees may be required
Refinancing may be difficult if values or income fall

A specialist commercial mortgage broker can:

Access multiple lenders
Match the case to lender criteria
Package financial and property information
Explain available structures
Negotiate terms
Coordinate with valuers and solicitors

A broker does not guarantee approval. Ask whether the broker has whole-of-market or restricted access, how fees are charged, whether commissions are paid by lenders and whether the firm has the relevant FCA permissions for any regulated activity. Compare the total cost of finance rather than the headline rate.

3. Bridging loans

A bridging loan is short-term, property-secured finance. It is used to provide funds before a sale, refinance or other committed source of repayment.

Bridges may be:

Open: no fixed repayment date, although a maximum term applies
Closed: a fixed repayment date or known repayment event

Interest may be:

Serviced monthly
Rolled into the balance
Retained from the advance
Structured through a combination of these methods

Lenders may take a first charge or second charge over the property. Additional security may also be required.

Typical uses include:

Auction purchases
Time-sensitive acquisitions
Chain breaks
Refurbishment
Planning or change-of-use projects
Properties temporarily unsuitable for mainstream lending
A gap before commercial mortgage refinancing

Advantages

Faster than many mainstream mortgage applications
Flexible underwriting
Can fund properties in poor condition
May support value-add works
Can be used where planning, lease or title matters are still being resolved, subject to lender approval

Disadvantages

Interest and fees are usually higher than long-term debt
The term is short
Extensions may be expensive
Rolled interest can increase the balance
Valuation reductions can require more equity
Failure of the exit can lead to default
The lender may enforce its security
The borrower may lose the secured property or other assets

A bridge should have a credible exit strategy supported by evidence. Examples include a sale with realistic market evidence, a refinance supported by lender indications, or another committed source of funds. Do not rely only on an assumption that values will rise or that a future lender will approve the refinance.

4. Other funding routes

Other structures may be suitable for larger or more complex projects.

Route	Typical use	Main point
Development finance	Construction, conversion or major refurbishment	Drawn in stages and linked to costs, progress and valuation
Mezzanine finance	Additional funding above senior debt	More expensive and may include profit participation or equity-like rights
Private credit	Specialist commercial acquisitions	Flexible terms, but pricing and security requirements vary
Secured business loan	Raising capital against existing assets	Can release funds, but increases security and repayment obligations
Asset-based lending	Finance linked to property or other business assets	Depends on asset quality and lender valuation
SSAS or SIPP	Eligible commercial property held through a pension structure	Specialist rules apply; residential property restrictions are important

Realty Packaging does not establish or administer SSAS arrangements. Investors should use an appropriately qualified pension adviser and administrator.

Company structure should also be considered. A limited company can provide operational separation and may assist with portfolio management, but lenders may still require personal guarantees. An LLP can provide partnership flexibility, but its agreement must clearly address contributions, profit allocation, decision-making and liability. Obtain legal and tax advice before choosing a structure.

Capital allowances and tax-advantaged property strategies may affect the overall return. Treatment depends on the asset, works, ownership structure and investor circumstances. Do not assume that all refurbishment costs qualify, or that a pension, company or partnership structure produces the same tax result.

5. Comparison of the main routes

Route	Advantages	Disadvantages	Key risks	Suitable profile
Investor equity	Shared risk, no scheduled loan interest, additional expertise	Dilution, profit sharing, reporting and possible disputes	Investor conflict and unclear exit rights	Investors with limited cash or larger projects
Commercial mortgage	Longer term, potentially lower cost and retained ownership	Slower process, deposit and covenant requirements	Valuation shortfall, rate rises and refinance risk	Borrowers buying stabilised, income-producing assets
Broker-arranged finance	Market access, packaging and negotiation	Broker fees, possible conflicts and no approval guarantee	Incorrect lender fit or misunderstood terms	Borrowers needing specialist commercial funding
Bridging loan	Speed and flexibility	Higher cost and short term	Exit failure, enforcement and compounded interest	Time-sensitive or transitional acquisitions
Development finance	Staged funding for works	Monitoring and cost controls	Cost overruns, delays and valuation changes	Experienced developers with clear budgets
Mezzanine finance	Fills a funding gap above senior debt	Expensive and may reduce profits or control	Subordinated security, complex intercreditor terms	Projects with sufficient margin and a robust exit

6. Illustrative funding examples

The following figures are examples only.

Senior debt and investor equity

Assume a mixed-use shop-and-upper property is purchased for £500,000.

Senior debt at 75%: £375,000
Deposit at 25%: £125,000
Assumed acquisition and refurbishment costs: £25,000
Assumed interest-only rate: 6%
Annual interest: £22,500
Monthly interest: £1,875
Equity investor contribution: £50,000

The purchase and stated costs require £150,000 of equity or other funds. If an investor contributes £50,000, the remaining £100,000 must be provided by the borrower or another agreed source.

The ownership, profit share, repayment priority, security and decision-making rights must be agreed before funds are committed. This example is not a recommendation.

Bridging example

Assume:

Purchase price: £500,000
Bridge at 70% LTV: £350,000
Term: 12 months
Assumed interest: 1.5% per month
Assumed arrangement fee: 2%

Simple interest for 12 months would be:

£350,000 × 1.5% × 12 = £63,000

The assumed arrangement fee would be:

£350,000 × 2% = £7,000

Total stated interest and arrangement fee: £70,000, excluding legal, valuation, administration and exit costs.

Actual rates, fees, LTVs and terms vary. If interest is rolled up, the balance and total cost may change.

7. Preparing for finance

Prepare a complete acquisition pack containing:

Acquisition brief
Purchase price and funding requirement
Deposit evidence
Mortgage statement where relevant
Property valuation
Income evidence
Affordability assessment
Proof of equity
Source-of-funds information
Written lender permission where relevant
Company accounts and bank statements
Personal financial information where required
Business plan and cash-flow forecast
Rent roll and lease documents
Existing rent and estimated rental value
Valuation information
Planning documents and lawful-use evidence
Building survey
Repair and refurbishment schedule
EPC and insurance information
Development appraisal, if relevant
Evidence supporting the exit plan

Lender due diligence should cover Realty Packaging’s Four Pillars:

Lease : rent, term, breaks, arrears, tenant covenant and landlord obligations.
Planning : lawful use, permissions, restrictions, proposed works and enforcement history.
Building condition : structure, services, defects, asbestos and costed works.
Operational compliance : fire safety, gas, electrical systems, EPC, insurance and management arrangements.

8. Choosing a lender, broker or investor

Before proceeding, verify:

Identity and company details
Relevant commercial and mixed-use experience
FCA permissions where applicable
Whole-of-market or restricted lender access
All fees and commission arrangements
Lender panel
Service levels and expected timescales
Conflicts of interest
Personal guarantee requirements
Default interest
Early repayment charges
Extension terms
Cross-collateralisation
Enforcement rights
Intercreditor arrangements

Obtain and review the full facility agreement, security documents and investor agreement. Do not rely solely on an indicative term sheet.

9. Key risks and stress testing

Test the proposal against:

A rise in interest rates
A longer void period
Rent arrears
Lower achievable rent
A valuation below the purchase price
Planning refusal or delay
Higher building costs
Delayed refurbishment
Failed refinance
A slower sale
Investor disagreement
Household-security risk
Personal guarantee enforcement
Family-lender risk
Cross-collateralisation
Lower market values
Limited cash reserves

For shop-and-upper properties, match long-term debt to stabilised income. Use bridging only where the exit is realistic. Verify the upper-floor planning status, condition and income. Consider staged value-add works where appropriate.

Do not underwrite a project on GDV alone. Investment value reflects the asset as an income-producing investment. Loan value is the value accepted by the lender for underwriting. GDV is the projected value after development or planning. These figures may differ materially, and GDV should not be treated as confirmed value without consent, costs and supporting valuation evidence.

10. Investor checklist

Before committing to a funding structure, confirm:

The total project cost
The required equity contribution
The loan amount and LTV
The full interest and fee calculation
The repayment type
The security and guarantee package
The planning and lease position
The building and compliance position
The income assumptions
The downside scenario
The exit strategy
The ownership and profit arrangements
The legal and tax advice required
The source and timing of all funds

Conclusion

Commercial property finance should be structured around the asset and its risk profile.

A commercial mortgage may suit a stabilised shop-and-upper with reliable income. Investor equity may reduce borrowing and provide access to additional expertise. Bridging finance may solve a timing or property-condition problem, but only where the exit is credible. Development finance, private credit or mezzanine finance may be relevant for larger projects.

The funding structure should be agreed after reviewing the property, borrower, costs, income, planning position, security and exit. Compare the total cost and risk rather than relying on headline rates or projected GDV.
