What Not to Do When Funding Your Renovation

Funding Renovation Work Without Reviewing Your Current Loan Structure

Most solicitors and barristers funding renovation work rely on redraw facilities or offset balances without confirming whether their existing home loan structure actually supports construction drawdowns. A standard owner occupied home loan with redraw access is not the same as a construction facility, and assuming you can draw funds progressively as invoices arrive often creates timing problems or forces you into higher-cost alternatives.

Consider a commercial lawyer with $120,000 available in redraw who plans a two-storey addition. The builder requires staged payments at slab, frame, lock-up, and final completion. The existing lender will not release redraw funds against builder invoices because the loan was not structured as a construction facility. The lawyer is forced to use a personal loan at a higher interest rate or negotiate delayed payment terms with the builder, neither of which were part of the original budget.

If you are planning structural work or an extension that requires progress payments, you need either a construction loan overlay on your existing facility or a separate construction split within your current loan package. Some lenders will convert part of your existing loan into a construction facility without requiring full refinancing, but this depends on your current lender's product suite and your loan to value ratio after the renovation is complete.

Borrowing Additional Funds Without Understanding Post-Renovation Valuation

Lenders assess your borrowing capacity for renovation funding based on the projected value of the property after the work is completed, not the current valuation. If your planned renovation will lift the property value by less than the amount you are borrowing, or if the post-renovation valuation does not support the increased loan amount, the application will either be declined or approved at a lower amount than requested.

A family lawyer with a property valued at $850,000 and an outstanding loan of $520,000 applies to borrow an additional $180,000 for a full kitchen and bathroom renovation plus landscaping. The lender orders a post-renovation valuation, which comes back at $980,000. The loan to value ratio after the work would be 71%, which falls within acceptable limits, but the value uplift of $130,000 is less than the proposed borrowing of $180,000. The lender approves only $110,000, leaving the lawyer to either reduce the scope of work or fund the shortfall from savings.

Post-renovation valuations are not guaranteed, and different lenders use different valuation panels. If your scope of work is extensive or involves structural changes, some lenders will require a quantity surveyor's report or detailed plans before providing conditional approval. This adds time to the application process, and if you have already signed a building contract with fixed start dates, delays in funding approval can create penalty exposure.

Using Offset Funds for Renovation Costs When You Hold Investment Debt

If you hold both owner occupied and investment property debt, using offset funds linked to your owner occupied loan to pay for renovations on that same property is usually appropriate. Using offset funds from an investment loan, or mixing offset balances across loan purposes, can create tax complications that reduce the deductibility of your investment loan interest. This is a common issue for lawyers who have built offset balances over time and assume all offset funds are interchangeable.

In a scenario where a litigation lawyer holds an investment property with a $400,000 loan balance and a linked offset account containing $95,000, and an owner occupied property with a $310,000 loan balance and $40,000 in offset, the lawyer plans to renovate the owner occupied property. Drawing the full $95,000 from the investment offset account to fund the renovation work would sever the connection between that portion of the investment loan and the income-producing asset. The Australian Taxation Office treats this as a change in loan purpose, and the interest on the $95,000 drawn becomes non-deductible.

If you need to access funds held in an investment loan offset for owner occupied purposes, the correct approach is usually to refinance or restructure the debt so that the investment loan retains its tax-deductible character. Some lenders allow you to split your loan into separate accounts with separate offset facilities, which gives you more control over how funds are allocated without creating unintended tax consequences.

Choosing a Fixed Rate Before Locking in Builder Contracts

Renovation timelines rarely align with initial estimates, and if you fix your interest rate before construction begins, you may face break costs if you need to increase your loan amount mid-project due to cost overruns or scope changes. A fixed rate home loan does not allow you to increase the loan amount without either breaking the fixed portion or applying for a separate top-up facility, and most lenders will not approve a top-up on a fixed loan unless the additional borrowing is structured as a separate variable split.

In our experience, lawyers who fix their rate before finalising builder quotes often underestimate contingency costs. Structural issues discovered during demolition, material price increases, or changes to council requirements can add 10% to 20% to the original contract price. If your loan is fully fixed and you need an additional $30,000 to complete the work, your options are limited to either paying break costs to increase the fixed loan, taking out a separate personal loan, or adding a small variable split at a potentially higher rate than the original fixed rate.

A split rate loan with a portion fixed and a portion variable gives you rate certainty on the bulk of your borrowing while retaining flexibility to increase the variable portion if the scope changes. This approach works particularly well when you have a signed building contract for the core work but expect minor variations or upgrades during construction.

Assuming Your Lender Will Approve Further Drawdowns Without a Revaluation

If you are using a construction facility or a loan with progressive drawdown capability, each drawdown request typically requires evidence that the work has been completed to the corresponding stage. Most lenders will not release funds for later construction stages without either a progress inspection or updated valuation confirming the work has been completed to the value claimed. If your builder is behind schedule or if completed work does not meet the lender's valuer's expectations, drawdowns can be delayed or reduced.

Barristers and solicitors working from home often combine functional renovations with workspace improvements, which can complicate drawdown approvals if the lender's valuer considers part of the work to be commercial fit-out rather than residential improvement. A criminal lawyer converting a garage into a library and client meeting room may find that the lender will only fund the structural and weatherproofing components, not the custom joinery or soundproofing, because those elements are considered business expenses rather than capital improvements that increase residential property value.

If your renovation includes elements that blur the line between residential and commercial use, discuss this with your broker before submitting the application. Some lenders are more flexible than others, and structuring part of the funding as equity release rather than construction drawdown can give you access to funds without the need for stage-by-stage inspections.
