Construction Financing: A Complete Guide for Developers and Property Investors
Securing capital to build a new commercial or residential project is fundamentally different from buying an existing yielding asset. With an existing building, the lender values the proven cash flow and the bricks and mortar. With construction finance, the lender is funding the creation of an asset that does not yet exist.
This guide explains how construction financing is structured, how lenders evaluate development risk, and what property developers must prepare to get a project funded successfully from groundbreaking to completion.
How construction financing is structured
Unlike a traditional commercial mortgage where the full amount is released at settlement, a construction loan operates on a drawdown facility. The lender releases funds in stages, commonly referred to as progress payments, as the build reaches specific engineering milestones.
- The developer pays interest only on the funds that have actually been drawn down, rather than the total facility limit.
- An independent quantity surveyor verifies that each stage of work is complete before the lender releases the next tranche of capital.
- A contingency buffer is built into the facility limits to cover unexpected supply chain delays or cost overruns.
This staggered facility is designed to ensure the lender's exposure always remains in line with the physical value of the incomplete project on site.
What lenders actually fund
Construction lenders categorise risk based on the asset class, the jurisdiction, and the exit strategy. Common development categories include:
Residential subdivisions and townhouses: These projects usually require strong pre-sales to prove market demand before the first drawdown is approved.
Commercial and industrial builds: Typically require a pre-lease agreement or a pre-commitment from an anchor tenant to validate the end value and commercial yield.
Retail, hospitality and mixed-use projects, from city hotels to holiday villa developments in Bali: Evaluated heavily on the operator's track record and robust local tourism or consumer metrics.
Project feasibility and key lending metrics
A lender will not fund a project based on architectural renders alone. The entire decision rests on the financial feasibility study. This model must demonstrate that the project is profitable enough to absorb delays, cost spikes, and market shifts while still comfortably repaying the debt facility.
Credit committees look closely at three main parameters:
- Gross Realisable Value (GRV): The total expected sales value of the completed project. Lenders cap their exposure at a maximum Loan to Value Ratio (LVR) against this figure.
- Loan to Cost Ratio (LTC): The maximum percentage of the total hard and soft development costs the lender will cover. The developer must fund the remainder through their own equity.
- Profit on Cost: The developer's expected net margin. If the projected profit margin is too thin, lenders will decline the application because any minor construction delay could wipe out the viability of the whole project.
The role of the builder and the contract
A project is only as bankable as the contractor building it. Even with a prime location and strong off-the-plan sales, a lender will refuse funding if the builder lacks the balance sheet capacity to complete the job.
Lenders almost exclusively require a fixed-price building contract. This shifts the risk of material price increases and labour shortages away from the developer and the lender, placing it squarely on the builder. The lender will run full due diligence on the builder's financial health, past project history, and current pipeline to ensure they are not overextended on other sites.
Bridging the equity gap with mezzanine finance
Senior lenders rarely fund 100% of a project's costs. They typically limit their exposure to 60 to 70% of the total required capital. The developer must inject the remaining capital upfront before the senior lender releases their first dollar.
When a developer wants to preserve cash or run multiple projects simultaneously, they use mezzanine finance or preferred equity to bridge the gap. This capital sits behind the senior debt in the security queue and carries a higher interest rate reflecting the risk, but it significantly reduces the developer's hard cash requirement, allowing them to break ground much sooner.
Getting your project funded
A successful construction funding application is a heavy administrative lift. Presenting a clear and robust feasibility model, securing a reputable builder on a fixed-price contract, and structuring the capital stack correctly are mandatory steps before a term sheet is ever issued. Focus entirely on derisking the project for the lender at every stage, and the capital will follow.
