Photo by Benjamin Child on UnsplashMost borrowers approach a bridging loan as a cost question: what is the monthly rate, and can I afford it during the term? That framing misses the more consequential decision. The interest structure you choose determines how much capital actually reaches your objective on day one, not just what you repay at the end.
A family office selling a Singapore property and buying into another before settlement completes needs every dollar at drawdown. A corporate treasurer funding a time-sensitive acquisition needs certainty of net proceeds before the transaction signs. A UK developer exiting construction debt wants to minimise the total interest bill and protect margin. These are different objectives, and each points to a different structure.
Financial bridging is, at its core, a capital-allocation decision. Treating it as a loan-cost question gets you the wrong answer.
The Three Structures: What Each Does to Your Capital
Retained interest is deducted from the advance at drawdown. If you borrow $5M and three months of interest is retained, the lender holds back the interest for the retained period and you receive the net. The advantage is certainty: you know exactly what lands before the transaction closes. The cost is reduced deployment.
Rolled-up interest lets you draw the full loan amount. Interest accrues and is repaid at exit alongside the principal. Nothing is deducted on day one, so every dollar or pound is available at drawdown. This is the structure that maximises deployment, and the one most relevant when you are bridging into a time-sensitive position where quantum matters.
Serviced interest is paid monthly. You draw the full amount but commit to regular payments throughout the term. The total interest bill is lower than a rolled-up loan because it does not compound, but it places a cash-flow obligation on you until exit. It works when the bridged asset or an adjacent business is generating income you can use to service the payments. If the cost comparison between those two is what you are weighing, we set out the arithmetic in rolled-up versus serviced interest; this piece stays with the deployment question.
Matching Structure to Your Financial Objective
Deploying into a second asset. A borrower bridging from a Singapore Good Class Bungalow into a new position before their sale settles needs maximum capital at drawdown. Retained interest shrinks the net proceed and can make the arithmetic of the next purchase fail. Rolled-up is the correct structure here. The exit is the sale, not income, which is why the TDSR framework (the income-based test that applies to bank mortgage lending in Singapore) is not the operative constraint. Our GCB bridging loans and prime London bridging loans are frequently structured this way for borrowers running positions across markets.
Funding a defined corporate transaction. A corporate treasury team needs to know net proceeds with precision before the deal signs. Retained interest provides that certainty: the lender calculates the hold-back upfront, and the treasurer can model exactly what arrives. Rolled-up introduces variability if the term runs beyond the initial estimate; retained removes it. If you are working back from a required net amount, discuss the structure with our team before committing to a gross loan size.
Preserving developer margin on an exit. A developer completing a UK scheme and refinancing out of construction debt wants to minimise total interest cost and preserve cash flow as the units begin selling. If sale proceeds are arriving during the term, a serviced structure can be cheaper overall than rolled-up. For an example of how we structure larger UK facilities, see our £9.5M loan facility secured against a UK regional hotel portfolio.
Maintaining positions across two markets. A family office holding assets in Singapore and the UK simultaneously may want rolled-up on one leg and retained on the other, depending on where capital is being deployed. Structure is negotiable and can differ across a portfolio of loans covering different assets and objectives, whether the security sits in Singapore or the UK.

When Financial Bridging Is Not the Right Tool
A bridge is a short-term instrument priced accordingly. The 3–24 month term means the annualised cost is higher than a bank mortgage. If your objective can be met by a term loan, or if your exit is not well-defined and credible, a bridge will cost more than the flexibility is worth.
We lend against the asset and the exit, not income. That is a strength for asset-rich borrowers who cannot meet a bank's income test. But the loan must be repaid from a real, near-term event. If that event is uncertain, speak to our team early: determining that a bridge is the wrong structure is part of what we do, and we say so. Our process page sets out how we assess exit credibility before issuing an indicative term sheet within 24 hours.
