The strategy needs a hub: one pool of money that everything routes through, that you can draw from on short notice and pay back on your own schedule. A line of credit does that job. So does the cash value inside a properly designed life insurance policy.

They're not equivalent, and the difference is control. A HELOC belongs to a bank. The bank set the limit, the bank can reduce it, and in 2008 and 2009 a lot of banks did exactly that to homeowners who had never missed a payment. Nothing about your behavior triggers it. A drop in local home values is enough. A policy loan works differently: the carrier is lending against a contract you own, there's no credit check, no committee, and no reason to call it as long as the policy stays in force and the loan stays under the cash value.

The tradeoff runs the other way on availability. Get approved for a line and you can chunk next month. A policy takes years to build a meaningful borrowing base, and the first two or three years are the slow part by design.

So a lot of households utilize both, and the sequence usually looks the same. The line does the heavy work against the mortgage now. Premium goes in every month regardless. Somewhere around year seven or eight the policy is carrying enough that it can take over as the hub, and the line becomes the backup that sits unused. Read your own illustration's net surrender column to find where that crossover lands for you, since design changes it by years.

Two things to keep straight. Policy loans accrue interest and they reduce both your cash value and your death benefit until they're paid back, so a loan you never repay eats the thing you built. And a policy that's been designed for maximum death benefit instead of cash value will not do this job at all, which is the whole reason the design question comes first. The mechanics of the loan itself are at what actually happens when you borrow against your policy.

If a line is the only hub you've got right now, read who can close the line your strategy runs on before you build anything else on top of it.
