A mortgage broker business in Australia is usually valued from the trail book: the right to keep receiving trail commissions on the live loans, minus runoff, clawback and any aggregator or appointment friction. A last-month figure times 12 times 2 is not a sale price.
Do not sign a sale, a loan against the book or a purchase deed until runoff, clawback, aggregator consent and the credit-representative appointment are written on one sheet. A CRM export cannot be transferred as an asset without a Privacy Act basis.

Trail Book Valuation
The trail book is the recurring trail commissions attached to loans you originated or hold under a servicing arrangement. Buyers pay for that income only if it is likely to continue after the names on the appointment change.
- Export the loan-level trail, runoff and clawback history.
- Ask the aggregator, in writing, who must consent and what fee applies.
- Price from that extract. Then write the schedule into the deed.
upfront commissions are one-off. They can lift a year of profit. They do not replace a trail multiple. Clawback on those up-fronts still sits with the broker unless the sale deed says otherwise.
A trail commission calculator is a quick arithmetic check. Due diligence still needs the loan-level file. For runoff, lender mix and client concentration use that extract, or mortgage broker software such as Track My Trail if that is the book you already run.
Primary Methods for Valuing Trail Books
Multiple of Trail Income
The usual method is a multiple of annual trail. Illustration only: $100,000 of expected annual trail at 2.5 times is $250,000. That 2.5 is not a 2026 published index. Live deals move with runoff, seasoning, arrears and who must consent to the transfer.
A cleaner book with older loans and low arrears can support a higher multiple. A book that depends on one lender or one large client usually does not.
Discounted Cash Flow (DCF)
A DCF projects the trail you expect to keep, then discounts it. You still have to choose a discount rate and a runoff path. Those are judgements, not a calculator output.
The projection has to survive a change in interest rates. The cash-rate target was 4.35% after the 11 August 2026 hold. A refinance wave can cut the book faster than last year’s runoff.
Comparative Market Analysis
Comparable sales only help when you can see a similar book that actually sold, including its size, lender mix, seasoning and aggregator rules. Most trail sales are private. A rumour multiple is not a comparable sale.
Factors Considered in Trail Book Valuation
Check these on the loan-level extract, not the monthly summary:
- Age of Loans (Seasoning): Newer loans carry more clawback and more refinance risk.
- Arrears Rate: Loans already in hardship are weaker income.
- Clawback Rate: Early discharge or refinancing can claw upfront. The sale deed must say who wears that after completion.
- Mix of Funders: One-funder books are cheaper. Confirm the buyer can be appointed to those panels.
- Runoff Rate: Discharges and external refinances that stop the trail.
- Portfolio Trends and Concentration: One suburb, one loan type or one client can move the multiple more than the headline trail.
Client Data, Appointments and Market Conditions
The largest asset is usually the trail right, not the office furniture. The client list and the process notes only have value if they can legally move with the book.

Intangible Factors
- Client Database: Relationships help retention. A Privacy Act 1988 basis is still required before you hand the file to a buyer.
- Brand Processes: Documented lodgement and review steps the buyer can run next week.
- Intangible Assets: Aggregator goodwill, panel appointments and any licence that is not automatically transferable.
Market Dynamics and Pricing Trends
MFAA figures for the March 2026 quarter put brokers at 81.0% of new residential lending, with leading aggregators settling $124.88 billion. Share of flow does not set your multiple. Financial-planning and real-estate books use different metrics. Do not import those multiples onto a mortgage trail.
Strategic Considerations for Buying and Selling Trail Books
For Sellers:
- Keep a loan-level trail history and a written runoff series the buyer can replay.
- Ask the aggregator, in writing, what consent and transfer fee the current agreement requires.
For Buyers:
- Rebuild the trail from lender or aggregator reports, not from a spreadsheet the seller typed.
- Price the book from runoff and clawback, not from the asking multiple.
The Role of Technology in Trail Book Valuation
Software can rank runoff and concentration. It does not replace the sale deed or the aggregator consent letter. Treat a model score as a workpaper, not as the price.
The Impact of Regulatory Changes on Trail Book Valuation
A change in responsible-lending, best-interests or commission rules can cut expected trail. Credit representatives still sit under a licensee. A sale that forgets the CL50 or appointment change can leave the buyer unable to service the book.
Evaluating the Worth of Your Mortgage Business
Use the trail history, not a single good month. Past runoff is the best available path for the next year, then stress it.
Historical Performance Considerations
- Borrower Performance: Arrears and hardship already on the book.
- Diversity of Lenders: How many panels the buyer must join to keep the trail.
- Loan Type and Credit Limits: Types of loans and remaining balances, not just headcount.
- Clawback History: How often up-fronts were reversed, and who paid.
- Drop-Off Rates: Clients who left the broker or the lender.
Determining the Multiplier for Trail Book Sale
Valuation multiples are illustrations, not a current market quote. Ask an active buyer, aggregator or accountant what comparable trail books are clearing for now, and test the figure against runoff, lender mix and the sale terms.
Example Calculation
- Trail Commission: $10,000 in one month is not $120,000 of durable annual trail. Deduct expected runoff before you multiply.
- Multiplier: Any 1.2 to 2 times figure on that projection is a worked example, not an offer.
Strategic Considerations for Selling
A book that is already shrinking is harder to sell. Plan the aggregator conversation while the runoff series is still stable. A late fire-sale after a panel loss usually cuts the multiple.
Increasing Business Value
Protect Trail and Prepare the Transfer
- Maintain Performance: Keep lodgement and service going through the sale window.
- Plan Exit Strategies: Write the consent path before you accept an offer.
- Strengthen Relationships: Retention after completion depends on client relationships the buyer can legally continue.
- Utilise CRM Systems: A Customer Relationship Management export is evidence for the buyer’s workpapers. The transfer still needs consent and the sale deed.
- Document Intangible Assets: List appointments, aggregator clauses and who owns the trail right.
Case Studies
Tom’s Mortgage Solutions
Illustration only. A buyer is shown $12,000 a month, or $144,000 a year, and an asking price of $288,000 at 2 times. After runoff and seasoning, the same working file might support $216,000. These names are not a published sale.
What Contributed to This Lower Than Expected Valuation?
- High Run-Off Rate: The book was discharging faster than the seller’s headline growth.
- Recent Deals: A pile of loans under two years still carries clawback.
- Growth vs. Loss: Illustration: 12% new trail against 20% runoff is a shrinking book, even if the monthly number still looks fine.
Runoff Evidence Reduced the Working Value
The loan-level runoff gave the buyer a number to put against the 2 times ask. Use your own extract. Do not quote Tom as a market print.
Linda’s Financial Services
Illustration only. A six-year book at $22,000 a month is shown at 2.3 times for a funding discussion. That multiple is not a bank offer. A lender that takes trail as security still runs its own credit policy.
What Drove This Higher Valuation?
- A-Grade Clients: Lower arrears and cleaner servicing notes.
- Low Clawback Rate: Fewer recent up-front reversals.
- Minimal Run-Off Rate: Clients staying on the original loans.
- Steady Growth: New lodgement without refinancing the same book into itself.
The Loan Schedule Supports the Funding Review
Put the loan schedule in the purchase deed so both sides can see which trail is included. Send the funding question to the commercial lender or accountant. Personal financial advice still needs an AFSL or a referral.
Deciding Whether to Hold, Sell or Borrow
Value the book from loan-level trail, runoff and the written consent path before deciding whether to hold, sell or borrow. Current aggregator transfer rules belong in the valuation file, and continuous education helps keep that evidence accurate.
