Refinancing Multiple Properties: Sequencing, Valuations, Cashflow

Key Takeaway

Refinancing multiple properties at once is safest when investors sequence loans deliberately: prioritising properties that boost cashflow or reduce risk, using conservative portfolio valuations, and keeping 3–6 months of cashflow buffers intact. With Australian lenders applying at least a 3% serviceability buffer (APRA), borrowers must model whole-portfolio repayments before signing any discharge. The most effective actionable step is to map each property’s current and post-refinance cashflow and then refinance in two or three stages, not all at once.

Refinancing multiple properties at once is doable, but you should almost never move them all in one hit. The safest approach is to refinance in stages, starting with the properties that either improve cashflow the most or remove the most risk, while using conservative valuations and protecting your cash buffers.

Here’s how to make that decision this week.

Step 1: Map your portfolio and cashflow first

Before touching a single loan, build a simple portfolio snapshot.

List for each property:

Current lender, rate and repayment (P&I or IO)
Loan balance and limit
Estimated value and LVR
Weekly rent and non‑finance expenses (rates, strata, insurance)

Then add your business and personal context:

Average monthly business drawings or salary
Volatile vs stable income streams
Cash buffers (household + business) in months of expenses

For investors and small business owners, each property should ideally hold its own on cashflow without relying on optimistic business drawings or future tax refunds (see also /insights/small-business-owners-gearing-into-property-risks-protections).

Quick worked example

Assume:

3 properties, total debt $2.1m, average rate ~6.5%
Combined repayments $11,000 per month
After rent and expenses, the portfolio is –$2,000 per month

If you can refinance two of the loans down to 5.8% (illustrative only), portfolio repayments might fall to ~$10,100 per month. If rent and other costs stay the same, the cashflow shortfall shrinks to around –$1,100 per month. That’s the kind of uplift you want early in the sequence.

Step 2: Decide the right sequencing order

Sequencing is about risk and cashflow, not ego or convenience.

In most cases you:

Refinance the highest-rate / worst-structured loans first
Think legacy interest‑only loans with no offset, or high‑rate second‑tier lenders.
Leave your strongest security until last
A low‑LVR, high‑equity property can be a “spare tyre” if a valuation or application goes sideways later.
Avoid cross‑collateralising the new structure
Where possible, don’t let one lender tie all titles together – it kills flexibility if you need to sell, restructure or move one property in future (especially for small business owners).
Match loan purpose to security
As you tidy things up, separate business borrowing from home/investment loans instead of rolling everything into a 30‑year mortgage, which usually increases total interest and concentrates business risk on the family home.

Often the practical answer is to sequence in two or three waves:

Wave 1: 1–2 properties that improve cashflow and clean up risk
Wave 2: Stronger securities or more complex structures
Wave 3 (optional): Fine‑tuning, equity access for future plans

Step 3: Use valuations strategically (full vs desktop)

The valuation call is one of the biggest levers in a multi‑property refinance. ### Desktop or AVM valuations Desktop (or AVM) valuations are quick, cheap and often used when: - LVR is comfortably under 80% - You’re not releasing much equity - Markets are stable and recent comparable sales are clear Pros: - Faster approvals, fewer delays - Less risk that one low val torpedoes the whole deal Cons: - Conservative results in patchy markets - Limited ability to argue if it comes in low ### Full valuations Full vals…

Frequently asked questions

Is it safe to refinance all my investment properties at once?▾

It’s technically possible but usually not wise. Moving everything at once concentrates valuation, policy and cashflow risk into a single moment. A staged approach lets you fix the worst loans first, check the actual repayments and valuations, and then decide whether to proceed with the next wave. That flexibility is especially important if you’re self‑employed or your income is lumpy.

Should I use desktop or full valuations when refinancing a portfolio?▾

Desktop valuations are faster and work well for low‑LVR, standard properties where you’re not chasing every last dollar of equity. Full valuations are better if you’re close to 80% LVR, have done renovations, or the property is unusual. Many investors use desktop valuations for simpler securities and full valuations only where the LVR outcome really matters.

How do I protect business cashflow when refinancing investment loans?▾

Start by separating business and personal cash buffers and avoid using your home loan as a revolving source of business working capital. Model the whole portfolio’s post‑refinance repayments against your typical drawings, at current rates and higher stress‑test rates. Use separate loan splits for any business‑related borrowing so you can track repayments, tax treatment and future refinancing options clearly.
