A file takes roughly the same hours whether it is $300,000 or $1.3 million. Raising the average is the growth lever that does not cost time, and most brokers have the larger files already in their database.

Volume is files times average size. Most brokers push the first number and ignore the second, even though the second is easier. The larger files are usually already in the database: the self employed client who mentioned a building, the investor with four doors, the professional buying a practice, the past client refinancing to consolidate. Keeping those files instead of referring them away is where the average moves.
Self employed, investor, commercial, construction and private files are larger on average and currently leave your book. Read the files you turn away.
A client with four properties refinances in sequence and buys a fifth. Portfolio files are larger and repeat. Read investor mortgages.
The first commercial file a residential broker keeps is commonly several times their residential average, and the Deal Desk runs it with them. Read new to commercial.
Debt consolidation, renovation, an investment purchase, a business injection. A renewal conversation that asks what the client is planning finds them.
Accountants, business lawyers and commercial realtors see larger transactions than residential realtors do. One of each changes the average.
A broker funding sixty files at a $450,000 average funds $27 million. The same sixty files at a $550,000 average is $33 million. Same hours, same client count, twenty two percent more volume, and it came from keeping ten files that used to be referred out.
See how brokers here grow with direct access to more than 100 lenders, the Deal Desk and weekly lender training.
Larger files are usually harder files, which is why they get referred away. A brokerage with a Deal Desk, a lender panel that covers self employed, investor, commercial and private, and an underwriter who has placed those files is what turns a referral out into a funded file in your book. Read the five levers for where this sits among the others.
Brokers here follow eight stages, from the first client to a business that does not depend on the broker's hours. Head office carries processing, compliance review and payroll. The Deal Desk carries the commercial and alternative file. What we do not do is hand out leads, because brokerages that promise them rarely deliver. We provide the infrastructure. You build the book.
