What Not to Do When Refinancing to Buy a Second Property

Refinancing to release equity from your Mount Macedon property creates a deposit for a second home or investment.

The process involves increasing your current loan so the additional funds can be used elsewhere. Most lenders will allow you to borrow up to 80% of your property's current value without needing mortgage insurance, which means the calculation depends entirely on what your home is worth now and what you still owe.

How Lenders Calculate Your Usable Equity

Usable equity is your property value multiplied by 80%, minus your existing loan balance. If your Mount Macedon home is valued at the current median and you owe $350,000, the lender multiplies the valuation by 0.8, subtracts what you owe, and the remainder is what you can access. That figure becomes your deposit, minus the costs involved in both refinancing and purchasing the second property.

Refinancing costs typically include valuation fees, discharge fees from your existing lender, and settlement costs. The second purchase adds stamp duty, conveyancing, and any building or pest inspections. These amounts reduce what you can actually put toward the new property, so the calculation needs to account for both transactions at once.

The LVR Limit That Catches Most Buyers

Lenders assess your borrowing capacity across both properties as a combined position. You might have enough equity to fund a deposit, but if the total loan amount pushes your loan to value ratio above 80% across both homes, the lender will either decline the application or require lender's mortgage insurance. This happens more often in regional areas like Mount Macedon where valuations can vary depending on the valuer and recent comparable sales.

Consider a buyer who owns a home valued at $750,000 with $320,000 owing. They want to purchase an investment property for $550,000. The refinance releases $280,000 in equity, which covers the deposit and purchase costs. But the new loan on the Mount Macedon property becomes $600,000, and the investment loan is $440,000. The combined borrowing is $1,040,000 against total property value of $1,300,000, which sits at 80% exactly. If either valuation comes in lower than expected, the entire structure fails.

Cross-Securisation and Why Most Brokers Avoid It

Cross-securisation means using both properties as security for both loans, which locks them together. If you want to sell one property later, the lender must agree to release it from the security pool, and that process can delay settlement or block the sale entirely. It also means any equity in either property is tied to both loans, which limits your flexibility if you want to refinance one loan separately or access further funds down the line.

The alternative is to keep the loans separate, with the Mount Macedon property securing its own increased loan and the new property securing its own purchase loan. This structure requires sufficient income to service both loans independently, but it gives you full control over each asset. Most brokers recommend separate securities unless your borrowing capacity or deposit size makes cross-securisation unavoidable.

Serviceability Across Two Loans

Your income needs to service both the refinanced loan and the new purchase loan at the same time. Lenders assess this using a buffer rate, which is typically 3% above the actual interest rate, and they apply living expense benchmarks based on your household size. If you are purchasing an investment property, they will include rental income but usually only 80% of the expected rent to account for vacancies and management costs.

In our experience, borrowers in Mount Macedon often underestimate how much the refinance increases their monthly repayment on the existing property. If your current loan is $350,000 and you increase it to $600,000, the repayment rises significantly even if the rate stays the same. That higher repayment reduces how much you can borrow for the second property, which can mean the purchase price needs to be lower than you initially planned.

What Happens If the Valuation Comes In Low

Property valuations in Mount Macedon can be conservative, particularly for homes on larger blocks or with unique features that do not have close comparables. If the valuer assesses your property below what you expected, your usable equity drops and the entire transaction can fall through. You cannot challenge a bank valuation in most cases, but you can request a second valuation with a different valuer if the first one seems unreasonable.

The other option is to accept the lower figure and adjust the purchase price or deposit size for the second property. Some buyers choose to go above 80% LVR and pay lender's mortgage insurance, but that adds several thousand dollars to the upfront cost and does not make sense unless the investment property is time-sensitive or the purchase price is unlikely to be available again.

Timing the Refinance and the Purchase

The refinance must settle before the second property purchase settles, because the funds need to be in your account to complete the deposit and cover the purchase costs. Most refinances take three to four weeks from application to settlement, and most property purchases have a 30 to 60 day settlement period. That means the refinance application needs to start as soon as your offer on the second property is accepted, or even earlier if you are purchasing at auction.

If the refinance is delayed, you risk being unable to settle on the second property, which can result in losing your deposit or being sued for specific performance. Running both transactions in parallel requires coordinating valuation bookings, loan documentation, and settlement dates across two lenders and two conveyancers. A mortgage broker manages that coordination so nothing falls through due to timing.

The Income Evidence Lenders Need for Two Properties

Lenders require recent payslips, tax returns, and notice of assessment documents to verify your income. If you are self-employed, most lenders need two years of financials and a letter from your accountant. For the investment property, they also want a rental appraisal or a signed lease if tenants are already in place. That rental income is added to your serviceability calculation, but only after the lender applies their 80% adjustment.

If your income has changed recently, or if you have other debts like car loans or personal loans, those will reduce your borrowing capacity across both loans. Some buyers consolidate smaller debts into the refinance to improve serviceability, but that only works if the total loan amount still stays within the lender's LVR limits.

Why Mount Macedon Properties Can Complicate Approvals

Mount Macedon is a tightly held market with a mix of lifestyle properties, bushland blocks, and heritage homes. Lenders view rural and semi-rural locations differently to metro suburbs, and some lenders will not lend above 70% or 75% in postcodes they classify as regional. That reduces your usable equity and can block the refinance entirely if your current lender will not go to 80%.

The other issue is bushfire risk. Properties in or near the Macedon Ranges may fall into a bushfire attack level zone, which affects insurance premiums and lender appetite. Some lenders will not refinance properties with a BAL rating above a certain threshold, or they will apply a lower LVR cap. If your property is affected, you need to work with a broker who knows which lenders will still approve the loan and at what percentage.
