Refinance vs. Home Line of Credit

The structural difference

A refinance replaces your existing mortgage with a new one. You receive a defined amount as a lump sum, on a set term, with a set payment schedule.

A Home Line of Credit — often called a HELOC — is a revolving facility secured against your home. An approved limit is registered, and you draw against it as needed, repay, and draw again within the limit.

Payments and interest

• Refinance: a scheduled payment covering principal and interest, amortized over the agreed period, generally at a rate fixed or variable for the term.
• Home Line of Credit: payments typically relate to what you have drawn, commonly interest-only as a minimum, at a rate that usually moves with the lender's prime rate.
• Refinance: predictable, which suits budgeting.
• Home Line of Credit: flexible, which suits uncertain or staged spending — and requires more discipline, because a minimum payment does not reduce principal.

When a refinance tends to fit

• You need a specific, known amount now.
• You want a defined repayment schedule that pays the balance down.
• You also want to change the terms of your existing mortgage.
• You are consolidating balances and want them genuinely amortized rather than revolving.

When a Home Line of Credit tends to fit

• The amount or timing of your need is uncertain — staged renovations, for example.
• You want access available without drawing it immediately.
• Your existing mortgage has terms you would prefer not to disturb.
• You are comfortable managing a revolving balance.

What they have in common

Both are secured against your home. Both are measured against the same general lending-value references, described in more detail in understanding the 80% loan-to-value limit. Both require qualification, and being approved for one does not imply approval for the other.

Combination structures

Some lenders offer arrangements that pair mortgage financing with a credit line under one registration. Availability and terms vary considerably by lender, so this is worth reviewing against your actual circumstances rather than as a general assumption.

How to choose

Start with the goal, not the product. Once the goal is specific — an amount, a timeline and a repayment intention — the appropriate structure usually becomes much clearer.
