Every broker knows there are deals sitting in the back of their book. The problem has never been believing that — it's finding them. Working out who genuinely benefits from a refinance means pulling a rate, guessing at a penalty, and doing arithmetic on the back of a page, one client at a time. So it doesn't get done, and the opportunity stays theoretical.
BrokerDam does that math across your funded deals, so the call list is a product of the numbers rather than a hunch.
The penalty math, done right
A refinance conversation lives or dies on the prepayment penalty, and the penalty is the number most often guessed. BrokerDam estimates it the way lenders actually calculate it: three months' interest compared against the interest rate differential (IRD), using the mortgage's rate and remaining term.
That distinction matters. On a fixed mortgage taken at a high rate, three months' interest and IRD can be an order of magnitude apart, and which one applies decides whether the deal is obvious or impossible. Rounding to "probably a few thousand" produces conversations that fall apart when the payout statement arrives.
Net-benefit analysis
A lower rate is not a benefit on its own. For a candidate refinance, BrokerDam weighs the savings available at today's rates against the penalty and the costs of doing the deal, and reports what's left.
That gives you something to put in front of a client that survives scrutiny: here is what you'd save, here is what it costs, here is the difference, here is how long it takes to get there. It's a defensible number, not a pitch — and when the number doesn't work, you find out before you've spent a week on it.
Portfolio-wide view
None of this is useful one file at a time. Your funded deals sit together with their rates and maturity dates — the raw material for spotting who is carrying an expensive rate, who has term left worth acting on, and who is close enough to maturity that a renewal conversation is the better move.
Looking at the book as a whole changes what you do with a rate move. When the market shifts, the question stops being "should I call some people" and becomes a shortlist of clients where the math already works.
Turn analysis into outreach
When the numbers work, the next step is right there. The client, their full history, the original deal and its documents, and email or SMS outreach all live on the same file — so identifying the opportunity and acting on it aren't two systems and a copy-paste.
You send the message, the reply threads back onto the file, and if it turns into a deal it starts with everything you already have on them.
One honest caveat: these are estimates for discussion. Actual prepayment penalties are set by the lender under the terms of the mortgage and should be verified with a payout statement before you advise a client to act.
Questions brokers ask
How are penalties estimated?
BrokerDam estimates the prepayment penalty the way lenders calculate it: three months' interest compared against the interest rate differential (IRD), using the mortgage's rate and remaining term. It is an estimate for discussion — the figure should be verified with the lender before you advise a client to act.
What is net-benefit analysis?
It weighs the projected savings from refinancing at today's rates against the prepayment penalty and the costs of doing the deal. The output is a net number, so the conversation is about whether the move actually helps the client rather than whether a lower rate looks better.
Does this replace lender payout statements?
No. BrokerDam identifies opportunities and gives you a defensible estimate to open the conversation. The lender's payout statement is the authoritative figure, and it should be obtained and relied on before any client acts.
Renewals and refinances are two halves of working your book: one is driven by the numbers, the other by a date. See how BrokerDam automates renewals →
