Modular Home finance: CBA’s prefab shift and what it means for you

Modular Home projects have moved from niche to mainstream, and the finance is finally catching up. In simple terms, major lenders now recognise how prefab actually gets built: most of the cost is incurred off‑site, long before a slab is poured. That change matters. If you’re weighing up a Modular Home Loan for a backyard studio, a family-sized dwelling, or a Modular Home Melbourne build to beat long wait times, the funding mechanics are easier than they’ve been in years.

Why prefab financing has been so hard—until now

For years, construction lending assumed a traditional site‑built process. Prefab turns that sequence on its head. The modules are fabricated in a factory, transported, then installed quickly on site. The cash flow problem has always been the same: manufacturers need meaningful progress payments up front to start work, yet lenders historically wanted to see on‑site progress before releasing funds. Borrowers were stuck trying to cover big deposits themselves, or projects stalled while the money caught up with the build.

In a tight housing market—short on trades, short on materials, and short on time—that gap made little sense. Prefab is faster on site and more predictable in the factory, but until lenders aligned their policies with how prefab actually happens, many buyers were left waiting.

What CBA is doing differently

CBA has announced a pathway that recognises the off‑site nature of prefab and supports manufacturer progress payments. In practical terms, the bank can release a significant portion of funds before the modules are delivered to site when the build is with a CBA‑accredited prefab manufacturer. The remainder is paid when the home is installed and finished on site.

For borrowers, that’s the unlock. Instead of scrambling to cover large factory deposits out of pocket, funding can move in step with the real work—fabrication first, installation second. The result is a cleaner path to contract execution, fewer cash‑flow crunches, and a shorter wait between “yes” and “home”.

The other familiar piece still applies: standard residential lending settings. In many cases you’re working around typical loan‑to‑value ratios (often circa 80%) and the usual income and credit checks. But the sequence of payments is the breakthrough, because it matches the way prefab gets built.

Who this helps most

The obvious winner is the time‑poor owner or investor who wants a turnkey outcome without months of on‑site disruption. Factory work happens while site prep is sorted, then installation is measured in days, not seasons. That matters if you’re looking to add living space quickly or get rental income into your cash flow sooner.

Investors also get a clearer path to small‑footprint, income‑generating add‑ons. A modular home granny flat on a compliant block can boost yield and flexibility without over‑capitalising the main dwelling. For many households, it’s a way to support family, create a home office or studio, or add a short‑ or long‑term rental—without a year of scaffolding in the backyard.

Small builders and prefab manufacturers benefit too. With accredited arrangements in place, they can start fabrication with confidence that client finance will land in time. That reduces stop‑start production and smooths the pipeline of work, which ultimately lowers risk for everyone involved.

What to watch: valuation, zoning and resale

Prefab doesn’t sidestep the fundamentals. Councils still regulate what can go where, so block suitability and zoning remain front and centre. Valuers will look at comparable sales and permanence of the structure; some buyers and lenders are still catching up on how modern prefab holds value over time. The market is moving in the right direction, but it’s smart to plan for the valuation conversation early—especially if your design is unusual or your area has limited prefab comparables.

Site readiness also matters. Access for delivery, services, footings or piers, and timelines for connection can all affect when the “final” claim is triggered. The good news is that once modules arrive, installation is swift. Most of the build quality is locked in at the factory; on site you’re really completing, connecting, and commissioning.

Where this is heading

CBA may be first out of the blocks with a fully thought‑through prefab pathway, but they won’t be the last. As demand grows and projects settle successfully, expect more lenders to formalise similar policies. The combination of faster delivery, predictable factory quality, and a funding model that recognises off‑site work is hard to ignore in a market that needs more homes, faster.

If you’re exploring a Modular Home Loan—whether for a primary residence, investment, or an addition in Melbourne or regional Victoria—now is a good time to get advice. The policy detail matters: accredited manufacturers, staged payments, valuations that reflect the finished product, and how your income and deposit position line up with lender settings.
