Rolled-up vs serviced interest: what each structure costs a bridging borrower

When a borrower is choosing between a rolled-up and a serviced interest structure, the question is not simply about which costs more. It is about timing, cash flow, and how the lender calculates the available loan against your asset on day one.

Both structures can produce identical total interest over a given term. The difference is when you pay: nothing during the loan with rolled-up interest, or monthly with serviced. That distinction has real implications for the gross advance available, the cash demands on the borrower during the loan, and what the exit balance looks like.

Rikvin Capital is a direct private lender operating in Singapore and the United Kingdom, lending to accredited investors and corporates. In Singapore, Rikvin is an excluded moneylender under the Moneylenders Act and is not bound by the TDSR framework; in the UK, underwriting is against the asset and the exit, not the borrower's income.

How rolled-up interest works

With a rolled-up structure, the borrower makes no interest payments during the loan term. Interest accrues monthly on the outstanding balance and is added to the debt. At exit, the borrower repays principal plus all accrued interest in a single payment.

The appeal is clear. A developer awaiting a buyer, or a Singapore property owner bridging a GCB acquisition, may have no income stream from the asset during the loan period. Rolled-up interest keeps cash free for costs, refurbishment, or working capital while the exit is arranged.

But there is a trade-off that borrowers sometimes miss. Because the terminal loan balance is higher (principal plus accrued interest), a lender underwriting to a maximum LTV against exit value must reduce the initial advance to stay within that ceiling.

A worked example: the LTV impact

Take a property with an exit value of $3M (or £3M). The lender caps the terminal balance at 65% of exit value: maximum terminal debt is $1.95M. On a 12-month facility at 1% per month (simple interest), total accrued interest is 12% of the principal. Working backwards, the maximum initial advance is approximately $1.74M, roughly 11% less than the $1.95M available on a serviced basis against the same security.

How serviced interest works

With serviced interest, the borrower pays interest monthly and the principal balance remains constant throughout the term. At exit, only the original loan amount is outstanding. For the lender, the terminal risk is lower; many direct lenders reflect this in their maximum LTV or pricing.

For borrowers who have rental income from the bridged property, or who are bridging a corporate acquisition and have operating cash flow from the business, serviced interest keeps exit debt lower. That matters when the exit depends on a refinance: a lower outstanding balance is easier for the incoming lender to underwrite.

The structure is common in prime London bridging loans, where borrowers often hold multiple properties generating yield and are comfortable meeting a monthly schedule. In Singapore, the same logic applies to shophouse borrowers with rental tenants in situ.

When serviced interest enables a larger facility

The additional advance available on a serviced basis is not academic. For a borrower bridging an acquisition at a fixed price (a London auction purchase inside the 28-day completion window, or a Singapore commercial property where the purchase price is set), serviced interest may be the only route to the required loan quantum without pledging additional security.

See how the structure played out in practice via the Holland Road residential bridging case study, where the loan was built around a clean exit with no monthly cash-flow requirement.

Which structure suits which borrower

Neither structure is inherently better. The right choice depends on three things: cash flow during the loan period, exit certainty, and the required loan size.

Rolled-up interest is usually the right choice when the borrower has no income stream from the bridged asset during the loan, the exit is clean and predictable (a confirmed sale, a refinance already in credit committee), and the required loan size is within what the lender can advance after factoring in accrued interest.

Serviced interest is usually the right choice when the borrower has rental income or business cash flow to meet monthly payments, the loan quantum is at the upper end of what the lender will advance against the asset, or the exit involves a refinance where a lower terminal debt changes the refinancing lender's decision.

A good private lender will model both structures before recommending one. The goal is matching the interest structure to the cash-flow profile and exit, not defaulting to whichever the borrower has heard of.

When a bridge is the wrong tool

A bridging loan, whether rolled-up or serviced, is a short-term instrument priced for short-term risk. Borrowers who are uncertain about their exit, with no confirmed sale or approved refinance in place, should resolve that uncertainty before drawing down. Extending a bridge or requesting an additional term costs more than completing the exit on schedule.

Borrowers who need multi-year debt should look at long-term financing rather than bridging. A bridge is not a substitute for a term loan, and structuring interest cleverly does not change that fundamental point.
