Semi-Commercial Second Charges: InterBay's Specialism

Semi-commercial properties — those with both residential and commercial elements, such as a flat above a shop or a mixed-use block — are notoriously difficult to finance. Many mainstream lenders decline them outright, and even specialist lenders can be restrictive about the commercial element's proportion of the total value. InterBay has built specific expertise in semi-commercial lending and is willing to consider second charges against properties where the commercial element is a meaningful proportion of the total.

This capability is valuable to landlords and investors who have built portfolios that include mixed-use units, as it provides access to equity release that would otherwise be unavailable. The lender assesses the rental income from both the commercial and residential elements when considering affordability, and its underwriters understand the different risk profile of commercial tenants compared to residential tenants.

For semi-commercial second charge enquiries, it is particularly important to use a broker experienced in commercial and investment property lending. The documentation required — including leases, rental schedules, and planning use class information — goes beyond what is needed for a standard residential second charge application.

Buy-to-Let Second Charge Mortgages

InterBay also offers second charge mortgages against standard buy-to-let residential properties, making it a viable option for landlords who want to release equity from their investment property portfolio. This is distinct from the more common scenario of a homeowner releasing equity from their main residence — InterBay specifically focuses on investors, which shapes how it assesses income and affordability.

For BTL second charges, InterBay will assess the rental income from the property against the proposed loan repayment, rather than the borrower's personal income alone. Portfolio landlords — those with four or more properties — can find InterBay's understanding of portfolio dynamics useful, as the lender takes a view of the overall portfolio position rather than applying a rigid stress test to each property in isolation.

Limited company and special purpose vehicle (SPV) structures used by property investors for tax efficiency are considered by InterBay, which is an important feature for investors who have moved their portfolio into corporate structures in recent years. This makes InterBay particularly relevant to borrowers who find that their personal income figures do not reflect the true scale of their property business.

"I kept putting off remortgaging because I thought it would be a massive headache. Honestly, the whole thing was painless — filled in a quick form, got my options, and it was all sorted within weeks. Wish I'd done it sooner."

"Our fixed rate was ending in a month and I was panicking about going onto the SVR. Managed to get everything sorted really quickly and we're now on a much better rate. Saving us about £200 a month."

"So Much Better Off"

Janet, Exeter
★★★★★
"Was a bit nervous about switching as I'd been with the same lender for years. Turns out I was massively overpaying — got a much better deal and the whole process was far easier than I expected."

"Happy Saving"

"After having to pay a ridiculous amount due to the interest rate hike, we have now got a more suitable monthly payment, consolidated a loan and have money left for hopefully a loft conversion."

OSB Group Membership and FCA Regulation

InterBay Commercial is part of OSB Group plc, a UK specialist lending group that also includes Precise Mortgages, Charter Savings Bank, and several other lending brands. OSB Group is listed on the London Stock Exchange and is subject to full FCA and PRA regulation, providing borrowers with confidence in the financial strength and regulatory standing of the group.

The group's scale means that InterBay benefits from shared infrastructure, technology, and funding while maintaining its specialist focus. For borrowers, the OSB Group membership is a positive indicator of stability — particularly relevant for longer-term loan products where the financial health of the lender over the loan term matters.

Borrowers accessing InterBay through a broker are protected by the FCA's consumer credit and mortgage regulations. This includes the right to receive a clear, compliant offer document before committing to the loan and access to the Financial Ombudsman Service if a dispute cannot be resolved with the lender directly.

Who Should Consider InterBay?

InterBay is most relevant to landlords, property investors, and developers who need to raise finance secured against investment or semi-commercial property. If you are a standard residential homeowner looking for a personal loan or debt consolidation, a different specialist lender will likely be more suitable and offer better terms for your circumstances.

The ideal InterBay borrower has a portfolio of investment properties — residential BTL, semi-commercial, or a mix — and needs to release equity for further investment, development, or another business purpose. The lender is not focused on consumer purposes such as home improvement or debt consolidation in the way that most second charge lenders are.

Using a broker who specialises in investment property finance is strongly recommended for InterBay applications. Standard residential mortgage brokers may be unfamiliar with the specific documentation, criteria, and process involved in semi-commercial and BTL second charges. A specialist broker can also compare InterBay against competitors such as Paragon Bank, Shawbrook, and UTB who also serve the investment property second charge market.

Important: Your home may be repossessed if you do not keep up repayments on your mortgage. There will be a fee for mortgage advice. The actual rate available will depend on your circumstances. Think carefully before securing other debts against your home.

Frequently Asked Questions

Yes, semi-commercial second charge mortgages are one of InterBay's key specialist areas. The lender can consider properties with a mix of residential and commercial use where many other lenders would decline. The proportion of commercial use, lease terms, and rental income from both elements all factor into the assessment. A broker experienced in commercial property is essential for semi-commercial applications.

InterBay considers applications from limited companies and SPVs used for BTL property investment. This is an important feature for investors who have incorporated their portfolios for tax efficiency. Your broker will confirm the current criteria for limited company applications and ensure the application is structured appropriately for the lender's requirements.

InterBay and Precise Mortgages are both part of OSB Group plc but operate as separate lending brands with different market focuses. Precise focuses primarily on residential mortgages including adverse credit products, while InterBay focuses on commercial and investment property. They share the same parent group but have distinct product ranges and distribution approaches.

No, InterBay operates exclusively through FCA-regulated brokers and intermediaries. Direct consumer applications are not accepted. For investment property second charge enquiries, using a specialist broker with experience in commercial lending is strongly recommended, as the application requirements and criteria differ from standard residential second charge products.

Maximum LTV for InterBay second charges depends on the property type, the borrower's profile, and the specific product. Semi-commercial and BTL properties may attract lower maximum LTVs than prime residential property. Your broker will confirm the current LTV limits available for your specific property type and circumstances as part of the initial eligibility assessment.
