Dollar-for-Dollar Refinancing: What It Is and Who It Helps

What the term means

It's broker and banker shorthand, not an official product. A dollar-for-dollar refinance means the new loan is the same size as the one it replaces. You owe $540,000 to your current lender, you borrow $540,000 from the new one, and no extra money changes hands.

Why the label matters

The Reserve Bank limits how much low-deposit lending banks can do. Those limits are why borrowing with less than 20% equity is hard. But the loan-to-value rules include an exemption for refinancing an existing loan where the amount doesn't increase. In plain terms, the Reserve Bank's rules don't stop a homeowner with 12% equity from moving to another bank, as long as they aren't borrowing more.

That matters most to people who bought with a small deposit, watched values dip, and assume they can't leave. Often they can.

What still has to stack up

The exemption removes one barrier. It doesn't oblige any lender to take you. Each still applies its own policy:

• Income and spending. The new lender assesses whether you can afford the loan, usually at a test rate above the real one. Some lenders are more flexible for a same-size refinance where your repayment record is clean. Some aren't. We don't name them because policies shift.
• Repayment history. Expect to show six to twelve months of on-time mortgage payments and tidy bank statements.
• Pricing. With under 20% equity, the new lender may add a low-equity margin or fee, and may not pay a cash contribution. Check the offer after those, not before.
• The property. The lender still needs an acceptable valuation and insurance.

Where the line is

Add anything to the loan and it stops being dollar-for-dollar. That includes rolling in a break fee, legal costs or a credit card. If you're in low-equity territory, keep the new loan at or below the current balance and pay the costs separately.
