Mortgage broker case studies

A case study is the most persuasive thing a brokerage can publish and the easiest to get wrong. Done properly it demonstrates competence that no amount of adjective can convey. Done carelessly it identifies a client, promises an outcome you cannot repeat, or reads like an advert with a name attached.

This is a treatment of how to write one that is useful, safe and honest.

The purpose is to show the mechanism

The reader is not interested in the happy ending. They are interested in whether you understood something they do not.

So the substance of a case study is the obstacle and the reasoning. Why did the first lender decline. Which part of the applicant's circumstances caused it. What was the alternative route, and why did it work. What evidence made the difference. What would have happened if one variable had been different.

A case study that says "the client came to us after being declined, and we found them a mortgage" tells the reader nothing and could have been written by anyone. One that explains how retained profit is treated differently by a handful of lenders, and what a company director needed from their accountant to demonstrate it, is genuinely instructive.

Anonymisation is not optional and not simple

Removing the name is the beginning, not the end. Mortgage cases carry special category-adjacent detail, and the combination of ordinary facts can identify someone easily in a small town.

Strip or generalise anything that combines into an identifier: the street, the development, the employer, the profession where it is unusual locally, exact purchase price, exact income, the month of completion, family circumstances such as a divorce or bereavement, and health information.

Then apply the local test. Could someone who knows the client recognise them from what remains? A self-employed vet buying a converted barn outside a village of two thousand people is identifiable regardless of whether you name them.

Where the case is distinctive enough that generalisation would destroy it, ask the client's permission explicitly, in writing, showing them the text you intend to publish. Consent given for a specific piece of text is meaningful; a clause in a client agreement is not. Record the consent and honour a withdrawal of it.

Composite cases, labelled as such

Where anonymisation is genuinely impossible, build a composite from several similar cases and say plainly that it is illustrative rather than a single client.

This is legitimate and often clearer, because it lets you present the typical shape of a problem rather than the idiosyncrasies of one file. It stops being legitimate the moment you present it as a real client, so the labelling matters.

What you cannot imply

Everything here is a financial promotion and must be fair, clear and not misleading.

Do not present a result as typical when it is not. A case where an unusual lender exception was granted is exactly the case worth writing about and exactly the one most likely to mislead, so it needs to be framed as unusual.

Avoid savings claims unless you can evidence the comparison and state what it was measured against. "We saved them two hundred pounds a month" invites the questions: compared with what, over what term, including what fees.

Do not guarantee or imply certainty of acceptance for readers in a similar position. The honest formulation describes what was possible in that case, given those facts, at that time.

Date the piece, and note that lender criteria change. A case study describing a route that closed eighteen months ago is misleading by omission if a reader assumes it is still available.

A structure that works

Keep it short. Six hundred words is usually plenty.

Open with the situation in one paragraph, in the client's terms. Then the obstacle: what stopped it working, described precisely. Then the approach: what you looked at, what evidence you gathered, why you went where you went. Then the outcome, stated plainly and without embellishment. Then a short section on what this means more generally, which is the part a reader in a similar position actually needs.

Resist the temptation to add a paragraph about your commitment to service. The case has already made the argument.

Getting the raw material

The barrier is never a shortage of cases. It is that nobody captures them while the detail is fresh.

Add a field to the case record for anything notable, and ask advisers to fill it in at the point of offer rather than reconstructing it months later. A sentence is enough: which lender, what the obstacle was, what resolved it. Once a quarter, someone reviews the entries and turns two or three into published pieces.

The cases worth choosing are the ones where the obstacle is common. A client with an unrepeatable stroke of luck makes a poor case study. A client whose situation reflects a pattern you see monthly makes a good one, because the readers who share it are numerous.

Where to use them

Case studies work hardest when they are attached to the relevant specialism page rather than filed in a general archive. A contractor reading about day rate assessment should meet a contractor case study on the same page.

They also travel well outside your website. Send one to an introducer to show them what you handle. Use them in the note you send a prospective client before a first meeting. Bring one to a training session with an accountancy practice.

Have your compliance process approve them the way it approves any other promotion, and put a review date on each one, because a case study is the piece of content most likely to describe a world that no longer exists.
