Common Mistakes Buying Vacant Land with a Home Loan

Vacant Land Loans Carry Higher LVR Risk Weights

Vacant land is classified as a higher-risk asset by lenders, which affects the loan amount, interest rate and deposit required. Under APRA's Prudential Standard APS 112, land without a habitable dwelling attracts a higher risk weighting than owner-occupied residential property, which means lenders hold more capital against the loan and typically pass that cost on through a higher rate. Most lenders will lend up to 80% of the land value without lenders mortgage insurance, though some restrict this further to 70% or require a larger deposit if the land is zoned rural or is located outside a metropolitan or regional growth corridor. If you need to borrow more than 80%, LMI applies, and the premium on land-only purchases is often higher than on established dwellings because there is no structure securing the loan.

A buyer purchasing a block in the Adelaide Hills for $250,000 with a 15% deposit would typically qualify for an owner occupied home loan at standard residential rates if the land were already improved with a dwelling. Without a dwelling, the same buyer may face a rate loading of 0.30% to 0.60% per annum depending on the lender, and some lenders will decline the application entirely if they do not offer a specific vacant land product. If the buyer plans to build within 12 months, some lenders will consider the combined land and construction value when assessing borrowing capacity, but only if the construction contract and building approvals are in place at application. Without those documents, serviceability is assessed on the land value alone, which reduces the amount you can borrow and can leave you short when construction finance is arranged later.

Stamp Duty Relief in SA Applies to Land Only if You Build

In South Australia, first home buyers can access full stamp duty relief on vacant land purchases, but only if the land is for the construction of a new home that will be occupied as a principal place of residence. The relief does not apply if you are purchasing land as an investment or if you do not intend to build. For contracts entered into on or after 13 February 2025, buyers are ineligible if they or their spouse or domestic partner own or have previously owned a residential property in Australia. The buyer must reside in the completed home as their principal place of residence for at least 6 continuous months commencing within 12 months of settlement. If you purchase the land and delay construction beyond the timeframes required by the scheme, you may be required to repay the stamp duty concession, and the liability sits with you, not the lender.

RevenueSA requires a declaration at the time of application for the concession that the land will be used for the construction of a home. If your plans change and you decide to hold the land without building, or if you sell the land before completing construction, you are required to notify RevenueSA and the concession will be reassessed. The repayment obligation can run for several years depending on the terms of the scheme at the time of your purchase. This is one reason lenders treating self-employed buyers often ask for evidence of building intent at the land purchase stage, even though construction finance is a separate transaction.

You Cannot Use Help to Buy or the 5% Deposit Scheme on Land Alone

The Australian Government 5% Deposit Scheme and Help to Buy scheme both require the property being purchased to be a habitable dwelling at the time of settlement. Vacant land does not qualify unless the purchase is part of a combined land and construction contract that results in a habitable home at completion. Some lenders participating in the schemes will accept a land and build package where the land and construction are financed under a single contract, but the guarantee or equity contribution from Housing Australia only applies once the dwelling is complete and valued as a residential property. If you purchase the land separately and arrange construction finance later, neither scheme applies to the land purchase, even if you intend to live in the home once built.

For buyers in Adelaide's northern growth corridor who are purchasing a titled block in a new estate, a combined land and build contract through a project builder may allow access to the 5% Deposit Scheme, provided the total contract value is within the SA price cap of $900,000 for capital cities and regional centres. The construction must result in a new dwelling, and both the purchase price and the lender's valuation must fall within the applicable cap. Buyers who want to purchase the land now and delay construction for 12 months or more will need to arrange a separate home loan for the land at standard LVR and rate settings, then refinance or top up the loan when construction begins.

Serviceability is Assessed on Current Use, Not Future Equity

Lenders assess your capacity to service a vacant land loan based on the income and expenses you have at the time of application, without accounting for the future value of a dwelling that has not yet been built. If you are borrowing $200,000 to purchase land and plan to borrow a further $400,000 in 12 months to build, the lender assessing the land loan will not consider the future construction in their serviceability calculation. This is relevant for self-employed buyers whose income is assessed using tax returns or BAS statements, because lenders apply the serviceability buffer at 3.0 percentage points above the loan product rate, and they assess the land loan repayments alongside your existing debts without any offset for the future dwelling.

In our experience, buyers who are land banking while waiting for development approval or who plan to build in two to three years often underestimate the holding cost of a land loan. If the land is not generating income and you are carrying the full interest expense, that cost reduces your serviceability for future borrowing. A buyer with $120,000 in net self-employed income who borrows $240,000 for land at a rate of 7.00% will pay roughly $16,800 per year in interest if the loan is interest-only. That interest expense reduces taxable income if the land is held as an investment, but if the land is intended for owner-occupation, the interest is not deductible and the full cost sits outside your tax return. When you apply for construction finance 18 months later, the lender will assess your capacity to service both the existing land loan and the new construction loan, and the combined repayments must fit within the DTI and serviceability buffer requirements in place at that time.

Interest-Only Periods on Land Loans Are Shorter Than on Investment Property

Most lenders will offer an interest-only period on a vacant land loan, but the maximum term is typically one to five years, compared to five to ten years on an investment loan secured by a dwelling. The shorter interest-only term reflects the lender's expectation that the land will either be developed or sold within a reasonable period. If the land remains undeveloped at the end of the interest-only period, the loan reverts to principal and interest repayments, which increases your monthly cost and may affect your capacity to borrow for construction if you have not yet started the build.

For a buyer who has purchased land in a growth area such as Playford or Barossa and intends to build within two years, structuring the land loan with a two-year interest-only period and a variable rate allows flexibility to refinance or top up the loan when construction begins without incurring fixed rate break costs. If you fix the land loan for three years and then need to refinance or increase the borrowing 18 months later to fund construction, break costs can run into thousands of dollars depending on the rate movement since you fixed. A variable rate on the land loan, combined with an offset account linked to the loan, allows you to park savings against the debt and reduce interest while keeping the funds accessible for the construction deposit when required.

Zoning and Title Type Affect Lender Appetite and LVR

Lenders distinguish between residential-zoned vacant land in established suburbs or growth corridors, rural land, and land in regional or remote areas when assessing risk and setting LVR limits. A titled residential block in a metropolitan or regional centre such as Mount Barker or Gawler will generally qualify for a higher LVR and a lower rate than a rural allotment outside a council-serviced area. If the land is part of a staged subdivision and the title has not yet issued, most lenders will not settle the loan until the title is registered, which can delay your purchase if the developer's timeline slips. Some lenders will offer pre-settlement finance or a deposit bond arrangement, but these products carry additional cost and are not available to all buyers.

If the land is zoned rural or is larger than 2.5 hectares, many lenders will treat it as rural or lifestyle property, which attracts a lower LVR and may require a specialist rural loan product. Land that is subject to a development approval condition or a staged release plan may also face stricter lending criteria, particularly if the buyer does not hold the building contract at the time of application. Buyers purchasing land in emerging growth areas such as Concordia or Seaford Meadows should confirm with their broker that the land is zoned residential, that the title is registered or will be registered before settlement, and that the lender's valuation panel is willing to provide a valuation in that location before exchanging contracts.
