Should I buy a mortgage broker’s book of business or the whole brokerage?

Sellers and listings use “book of business” loosely. Sometimes it means a list of past clients and the renewals that may come from them. Sometimes it means the whole firm, with its name, people and contracts. Before you compare offers, write down what you expect to receive in each case. The two routes carry different benefits and different risks, and a good conversation starts with that difference.

What a client book gives you

A book is mainly relationships: past clients, their files and the chance to serve them again. It usually comes without staff, premises or the company’s history, so there is less to inherit. Ask how the clients will hear about the change and whether they may choose to stay or leave. Ask your lawyer what consent and privacy steps apply before any client information is handed over.

What the whole brokerage adds

Buying the firm brings the licensed entity, its agents, its lender arrangements, its systems and its records. That can save time, because the operation keeps running. It also means you take on its past, including complaints, errors and contracts. Ask which approvals the regulator and each lender need when ownership changes, and whether lender arrangements carry over or must be set up again.

Questions that help you choose

• Who are the clients’ main contacts, and will they stay on?
• Which agents work in the firm, and are they staying?
• Which lender relationships are held by the firm and which by individuals?
• What does the file history show about past complaints or errors?
• Which records, systems and licences move with the deal?
