No monthly payments
Deducted interest requires no monthly servicing, which is ideal where the property produces no income during the loan term or where cash flow must be preserved.

Deducted and retained interest bridging loans
Pros of Deducted (Retained) Interest bridging loans
02
Certainty of cost upfront
Interest is calculated at the outset, giving clear visibility of total interest (assuming the loan completes within the agreed term). This can simplify budgeting.
03
Easier approval where income is irregular
Deducted interest is commonly used where borrowers have seasonal income, complex finances, or non-status lending, as no affordability testing for monthly payments is required.
04
Simpler cash flow management
Because interest is settled at redemption, borrowers can focus capital on acquisition, refurbishment or stabilisation without worrying about monthly outgoings.
05
Well suited to short, predictable exits
Where the exit is highly certain and time-bound (e.g. auction flip, known refinance date), deducted interest can be operationally efficient.
Cons of Deducted (Retained) Interest
01
Higher effective cost of borrowing
Interest is charged on the gross loan amount, even though part of the capital is deducted upfront. This increases the true cost of capital compared to serviced interest.
02
Interest paid on money never received
Because interest is withheld at the outset, borrowers pay interest on funds they do not control, which can materially reduce capital efficiency.
03
Punitive if timelines change
If the exit occurs earlier than expected, deducted interest is usually not refunded, increasing the effective annualised rate. If the loan overruns, additional interest is charged on the gross balance, escalating cost quickly.
04
Less flexibility on extensions
Extensions can be expensive, as further interest is added without releasing additional usable capital. This is where deducted interest can significantly erode profits.
05
Not ideal for uncertain exits
Where planning, legal or construction risk exists, deducted interest can amplify downside risk because time overruns directly increase cost.
