Construction Home Loans for Sydney Builders and Owners

Mortgagefy Broker Team · Published · Last reviewed

Construction loans are different from standard home loans. They release funds in stages as your build progresses, you pay interest only on what's drawn down, and the lender requires a fixed-price builder contract — or owner-builder evidence. We've helped Sydney families fund knock-down rebuilds, granny flats, custom builds and dual-occupancy projects.

Who this guide is for

The real challenge

Most major banks treat construction lending as a niche product and either decline outright or require unusually high deposits. Builder choice, contract type, valuation method, and progress payment schedule all become friction points.

Owner-builders face an even steeper challenge — many lenders won't touch owner-builder loans without significant equity and trade evidence.

How Mortgagefy helps

We know which lenders actively want construction business — and which ones treat it as an exception. We pre-screen your scenario, builder contract, and valuation expectation before lodging.

We've helped Sydney families fund builds from $400K to $3M+. Our goal is to make the progress payment process predictable so you and your builder don't get stuck mid-build waiting on funds.

Frequently asked questions

How does a construction loan work?

Funds release in stages — typically slab, frame, lock-up, fixing and completion. You pay interest only on what's drawn. Once construction completes, the loan converts to a standard P&I home loan.

How much deposit do I need for a construction loan?

Most lenders want 20% of total project cost (land + build) — some accept 10-15% with LMI. With a $1.4M Sydney project that's $140K-$280K deposit.

Can I be an owner-builder?

Yes — but it's harder. Most owner-builder loans require 30-40% deposit and trade experience evidence. We work with lenders who actively support owner-builders.

What happens if my build runs over budget?

Cost overruns aren't covered by the original construction loan. You'd need a contract variation or top-up loan, and lender approval. We help you set the contingency at the start to avoid this.

Can I use the First Home Guarantee for a construction loan?

Yes — the First Home Guarantee scheme allows construction. The land + build total must stay within the price cap for your area. We'll check your specific eligibility.
