The first time you borrow against your own policy can feel strange, because it doesn't work like any loan you've taken before. No application, no credit check, no explaining yourself. Still, the first one goes smoother when you know the steps ahead of time instead of learning them in a hurry. Here's the walkthrough.
First, know what's actually available. Your available loan value is a portion of your cash value, not the death benefit, and not every dollar of cash value is borrowable. Call the company or check your online portal for the current figure before you plan around it. This is also why learning the process before you need it, back in your first ninety days, pays off later.
Second, make the request. It's usually a short form or a phone call specifying the amount. The insurer lends you money from its general account using your cash value as collateral, so your cash value stays in the policy and keeps compounding while the loan is out. The money typically lands in your account within days, not weeks.
Third, and this is the step people skip, make a plan to pay it back. There are no required monthly payments, which is the feature and the trap. Loan interest accrues at your contract's rate, and unpaid interest gets added to the balance and compounds against you. Set your own repayment schedule as if the payment were required, because refilling the loan restores your available cash value and keeps the policy healthy for the next time you need it.
A word of caution that isn't fine print to me: an outstanding loan reduces your available cash value and your death benefit until it's repaid, and if a loan is left to grow unchecked it can eventually threaten the policy, which can trigger tax consequences from the IRS on the gains. Borrow on purpose, pay it back on purpose. The deeper mechanics are at Lifetime LOC, and the early setup steps are on Get Started.
