Pros of serviced interest bridging loans

01

Lower effective cost of borrowing

With serviced interest, you receive the full loan amount and only pay interest on capital you actually use. Over the life of the loan, this usually results in a lower total interest cost compared to deducted interest.

02

Fair cost alignment with time

Interest is paid monthly, so if you exit early, you stop paying interest immediately. This makes serviced interest more cost-efficient where exit timing is uncertain or likely to be earlier than planned.

03

No interest charged on withheld funds

Unlike deducted interest, there is no situation where interest is charged on money you never receive. This improves the true cost efficiency of the borrowing.

04

More flexible for extensions or delays

If a project overruns, interest increases linearly, not disproportionately. This makes serviced interest more forgiving where planning, legal or construction timelines are unpredictable.

05

Preferred for longer bridge terms

For longer short-term loans (9-18 months), serviced interest often produces better overall economics, provided cash flow supports payments.

Cons of Serviced Interest

01

Requires consistent cash flow

Serviced interest requires monthly payments, which can be problematic where the property produces no income during the loan term (for example, during refurbishment or development). Missed payments can trigger default interest or penalties.

02

Affordability scrutiny

Some lenders will assess the borrower’s ability to service interest, which can introduce additional underwriting checks. This may reduce lender choice for borrowers with irregular, seasonal or complex income.

03

Cash flow pressure during works

Monthly servicing can strain working capital, particularly on projects where funds are needed for construction, professional fees or contingency costs.

04

Less suitable for non-income-producing assets

Where the asset does not generate rent (e.g. vacant property, land, probate purchases), serviced interest may not be practical or may force the borrower to inject external cash.

Frequently asked questions

What is serviced interest on a bridging loan?

Serviced interest is paid monthly, like a mortgage, so it is not deducted from the loan. It maximises the net advance but requires income to meet the payments throughout the term.

What are serviced payments on bridging loans?

Serviced payments involve making regular interest payments throughout the loan term. This helps manage cash flow by spreading out the interest costs over time.

How is interest repaid on a bridging loan?

There are typically two methods for repaying interest on a bridging loan:

Serviced Interest:

    • Borrowers pay interest monthly, similar to a mortgage but calculated monthly.
    • Ideal for those with a regular income who prefer to manage cash flow through ongoing payments.
    • Ensures the principal remains constant but requires consistent cash flow for monthly payments.

Deducted (Retained) Interest:

    • Interest for the entire loan term is calculated and deducted upfront from the loan amount.
    • Suitable for borrowers without regular income during the loan term, such as property developers.
    • No monthly payments are needed, but the borrower receives less initial cash.

Choosing between these options depends on the borrower’s financial situation and strategy, making it essential to understand which aligns best with their needs.

What is retained interest on a bridging loan?

Retained interest is interest for the whole term calculated at the start and deducted from the gross loan, so there are no monthly payments. It reduces the net advance, and any unused interest may be refunded on early repayment, depending on the lender.

What is deducted interest in a bridging loan?

Deducted interest involves rolling up the interest payments into the loan amount, which is then repaid in full at the end of the term. This preserves cash flow during the loan term but results in a larger lump sum repayment.
