10 Things to Know Before Buying a Data Centre

Data centres are industrial assets with commercial property loan structures that differ significantly from standard warehouse or office purchases.

The buyer typically owns the building and infrastructure while tenants lease rack space or server capacity under long-term agreements. Lenders assess these facilities based on energy capacity, cooling systems, and tenant covenants rather than floor area alone. Understanding how loan structure aligns with operational revenue determines whether the investment generates the income needed to service debt and build equity over time.

How Lenders Value Data Centre Infrastructure

Lenders calculate loan amount based on income potential and replacement cost, not just land and building value. A facility generating $1.2 million annually in rack rental income with long-term contracts to enterprise clients will support higher borrowing than a comparable building used for general storage. The valuation includes redundant power systems, backup generators, fire suppression equipment, and HVAC systems designed for continuous operation.

Consider a buyer acquiring a data centre in the Liverpool industrial precinct with contracted tenants including a national telecommunications provider. The purchase includes N+1 redundant cooling, dual power feeds, and a 10-year lease with annual CPI escalation. The lender approved a loan structure at 65% LVR based on contracted income and replacement cost of the fit-out, totalling $8.5 million against a $13 million purchase. The buyer provided $4.5 million equity, which included the deposit and allowed for settlement costs including legal fees and connection charges for ongoing utility agreements.

Loan Structure for Income-Producing Facilities

Principal and interest repayments are structured around verified lease income rather than projected occupancy. The lender requires rental agreements covering at least 70% of the loan repayment amount before settlement. If the facility operates on short-term contracts or colocation arrangements without fixed terms, expect a lower loan amount or additional security.

You might use a variable interest rate to maintain flexibility as tenant agreements renew, or fix a portion if the lease term extends beyond five years. Some buyers split the loan with 60% fixed to match the core lease term and 40% variable to allow for early repayment if a tenant vacates or the facility undergoes expansion. Flexible loan terms also support progressive drawdown if you plan to add capacity or upgrade cooling systems after settlement.

What Documentation Lenders Require for Settlement

A commercial property valuation must include an income assessment showing current rent roll, lease expiry dates, tenant industry, and outgoings. The valuer inspects power infrastructure, redundancy levels, and cooling capacity to determine replacement cost. If tenants contribute to capital expenditure or hold options to expand, those terms affect the lender's assessment of future income stability.

You also need an environmental report covering hazardous materials, soil contamination, and compliance with energy regulations. Data centres consume significant power, and any history of grid failures or council disputes over load capacity can delay finance approval. The lender reviews utility agreements and capacity certificates to confirm the facility can operate at the level required by existing tenant contracts.

How Existing Lease Agreements Affect Borrowing Capacity

The length and quality of tenant covenants determine the loan amount more than the building's physical condition. A single tenant on a 10-year lease with annual revenue of $800,000 will support a larger loan than multiple short-term clients generating the same total income. Lenders assess tenant credit risk, lease structure, and whether agreements include rent reviews tied to CPI or market rates.

If a tenant holds an option to extend, the lender treats that as potential rather than contracted income. The same applies to vacant rack space or areas marketed for future colocation. Borrowing capacity reflects current verified income, not optimistic projections. When tenants renew or expand during the loan term, you can often approach the lender to increase the facility or adjust loan structure based on updated income.

Why Commercial LVR Caps at 65% for Specialist Assets

Data centres are considered specialist industrial assets, and lenders limit exposure because resale depends on a narrow buyer pool. A warehouse can convert to logistics or manufacturing, but a data centre requires significant capital to repurpose if tenants vacate. Most lenders cap LVR at 65%, though some may extend to 70% if tenant covenants are strong and the facility serves an established market like South West Sydney where demand for data hosting continues to grow alongside logistics and distribution sectors.

If you need to bridge a deposit shortfall, mezzanine financing is occasionally used to top up equity, though interest costs are higher and repayment terms are typically shorter than the primary loan. This approach suits buyers confident they can refinance or sell within three to five years once lease renewals are in place.

Fixed vs Variable Interest Rates for Long-Term Holds

Your decision between fixed and variable interest rates should match your lease structure and exit timeline. A buyer holding a facility with a single tenant on a 15-year lease might fix the rate to lock in repayments aligned with contracted income. A variable rate offers flexibility if you plan to sell within five years or expect tenant turnover that might require early loan repayment.

Some lenders offer redraw facilities on variable portions, allowing you to access surplus repayments if the facility requires unexpected capital expenditure such as cooling upgrades or generator replacement. Fixed portions typically do not include redraw, and early repayment can trigger break costs if interest rates have moved since you locked in the term.

How Settlement Differs from Residential Property Transactions

Commercial property finance requires detailed due diligence before settlement, and the process usually extends beyond the standard 30 to 60 days common in residential transactions. The lender orders an independent valuation, reviews tenant agreements, inspects environmental compliance, and confirms utility capacity. If any tenant is in arrears or a lease expires within 12 months of settlement, expect the lender to adjust the loan amount or request additional security.

You also coordinate with the seller to transfer maintenance contracts, utility agreements, and tenant bonds. Any equipment leased by the seller, such as backup generators or monitoring systems, must be disclosed and either assigned to you or removed before settlement. The lender will not fund the purchase until all encumbrances are cleared and the facility is ready to operate under your ownership.

When to Use Commercial Bridging Finance

If settlement timing is tight or you need to secure the property before long-term finance is approved, commercial bridging finance covers the purchase for up to 12 months. This suits buyers who have identified a facility with strong tenant income but require time to finalise documentation or improve occupancy before refinancing into a standard commercial property loan.

Interest rates on bridging finance are higher than variable rates on conventional loans, but the term is short and repayment is usually interest-only. Once the facility is stabilised and lease agreements are formalised, you refinance into a longer-term structure with lower interest costs and principal repayments that align with income.

Access to Lenders Who Understand Data Centre Assets

Not all lenders assess data centres the same way. Some treat them as standard industrial properties and undervalue the infrastructure, while others specialise in income-producing assets and recognise the premium associated with contracted tenants and redundant systems. A broker who works with commercial loans regularly can connect you with lenders who assess the facility based on operational income rather than just bricks and mortar.

You might also explore options through SMSF loans if you are purchasing the facility within a self-managed super fund, though borrowing capacity is typically lower and the loan must be limited recourse. For buyers expanding an existing portfolio that includes residential or retail assets, a broker can structure the loan to use cross-collateral where appropriate, though this approach reduces flexibility if you later want to sell individual properties.

Buying a data centre is less about the building and more about the income it generates and the systems that keep it running. Your loan structure should reflect tenant quality, lease terms, and the capital expenditure required to maintain redundancy and capacity. When those factors align with your equity position and the lender's appetite for specialist industrial assets, the transaction moves forward with clear repayment terms and a timeline that works for settlement.
