Understand monthly serviced, rolled-up, and retained interest options. Compare real costs with worked examples and choose the right payment method for your cashflow and exit strategy.
Each interest type works differently and suits different situations. Here's how each option works with real numbers.
You pay interest monthly throughout the loan term
Interest is calculated and charged monthly. For example, on a £200,000 loan at 0.50% monthly, you pay approximately £1,000 per month. This amount is paid to the lender each month.
Worked Example:
loan
£200,000
rate
0.50% monthly
monthly Payment
£1,000
six Month Total
£6,000
twelve Month Total
£12,000
Lenders prefer this option as it reduces risk - interest is paid throughout the loan, not just at the end
Interest accrues and is paid as a lump sum when you exit (sell or refinance)
Interest is calculated but not paid monthly. Instead, it accrues (compounds) and is deducted from your sale proceeds or paid when you repay the loan. On a £200,000 loan at 0.50% monthly for 6 months, interest compounds to approximately £6,150.
Worked Example:
loan
£200,000
rate
0.50% monthly
six Month Interest
£6,150 (compounded)
twelve Month Interest
£12,650 (compounded)
net Proceeds6 Month
£193,850 (from £200k sale)
net Proceeds12 Month
£187,350 (from £200k sale)
Lenders charge higher rates for rolled-up interest as they carry more risk - no interim cashflow
Interest is calculated upfront and deducted from the loan amount you receive
Interest is calculated for the full loan term upfront and deducted from the loan advance. For example, borrowing £200,000 for 6 months at 0.50% monthly: interest calculated as £6,150, so you receive only £193,850 while repaying the full £200,000.
Worked Example:
loan
£200,000
rate
0.50% monthly
six Month Interest
£6,150
advance Received
£193,850
repay Amount
£200,000
net Cost
£6,150
Lenders like this option as risk is minimised - interest is received upfront, regardless of exit

How each interest option affects your monthly and overall cashflow
| Interest Type | 6-Month Impact | 12-Month Impact | Cashflow Effect | Best When |
|---|---|---|---|---|
| Monthly Serviced | Must budget £1,000/month (total £6,000) | Must budget £1,000/month (total £12,000) | Requires ongoing cashflow management | You have regular monthly income |
| Rolled-Up | No monthly payments, pay £6,150 at exit | No monthly payments, pay £12,650 at exit | Improves monthly cashflow, lump sum at end | You have uncertain monthly income but certain exit |
| Retained | No ongoing costs, interest deducted upfront | No ongoing costs, interest deducted upfront | Best for monthly cashflow, lowest net advance | You need maximum monthly cashflow |
Different lenders have different preferences for interest payment methods. This affects the rates they'll offer you.
Monthly Serviced or Rolled-Up
They prefer monthly income or clear exit with accrued interest. Monthly payments reduce their risk exposure.
Standard rates (0.50-0.70% monthly)
Rolled-Up Interest
They understand development timelines and prefer not to disrupt project cashflow with monthly payments.
Slightly higher rates (0.55-0.75% monthly) for rolled-up option
Retained/Deducted or Monthly
They prefer interest paid upfront or monthly to reduce risk on short loans.
Competitive rates, similar across options
Monthly Serviced
Institutional money prefers monthly servicing patterns similar to mortgages.
Best rates for monthly option, premium for rolled-up
