refinancing home loan for investment property: key questions answered

Why consider a refi?

Investors refinance to lower rates, improve cash flow, or unlock equity for the next purchase. A well-timed move can shorten the term, reduce risk, and convert variable interest into a steadier fixed repayment.

What lenders look for

Lenders weigh rental income, loan-to-value, credit, and your debt-to-income ratio. Expect stricter buffers than on a home you live in, plus seasoned tenancy and low vacancy evidence.

Costs and timing

Factor break fees, discharge, application charges, valuation, and potential lenders mortgage insurance if equity is thin. Refinancing makes sense when savings exceed total costs within a reasonable horizon.

Quick checklist

• Compare rates, offsets, and redraw features, not just headline APR.
• Model cash flow with conservative rent and a 1-2% rate rise.
• Order a valuation to confirm usable equity.
• Ask about cross-collateralisation and how to avoid it.
• Keep buffers: three to six months of repayments in reserve.

Before you sign, run the numbers twice, get tax advice on deductible interest, and document a clear plan for the freed-up capital.
