How Off-the-Plan Finance Works
Off-the-plan (OTP) purchases differ fundamentally from standard property purchases in how finance is arranged:
- Exchange: You pay a deposit (typically 10%) and exchange contracts. Settlement — when you pay the balance and take ownership — occurs when the building is completed, which may be 1–3 years later.
- Pre-approval at exchange: Most buyers obtain pre-approval at time of exchange, but formal approval is only issued at settlement. The lender will conduct a fresh assessment at settlement — including a new valuation.
- The valuation gap risk: The most significant risk in OTP finance. If the property's market value at settlement is lower than the contract price, the lender will only lend against the lower valuation. You must fund the gap.
⚠️ The Valuation Gap Risk — Real Example
Contract price (2023): $850,000 — your deposit: $85,000
Valuation at settlement (2026): $790,000
Lender will lend 80% × $790,000 = $632,000
Your loan shortfall: $850,000 - $85,000 - $632,000 = $133,000 — needed at settlement
This is the valuation gap — and it catches many OTP buyers off guard.
Lender Restrictions on Off-the-Plan Apartments
Many lenders apply additional restrictions to OTP apartment finance that do not apply to established properties:
- Postcode and building restrictions: High-density apartment postcodes — particularly in inner-city Sydney, Parramatta, and some outer suburbs — may be capped at 70–80% LVR instead of the standard 80–90%.
- Apartment size: Most lenders will not lend on units with internal area below 50sqm. Some cap at 40sqm for certain postcodes.
- Developer reputation: Lenders assess the developer's track record. Projects from unknown or offshore developers may be declined or capped at lower LVRs.
- Percentage sold: Some lenders require that a minimum percentage of the building has been sold before they will approve finance.
First Home Buyers: OTP Advantages
For first home buyers, purchasing an off-the-plan property has specific advantages in 2026:
- First Home Owner Grant: The $10,000 NSW FHOG applies to new builds — including OTP purchases. Established properties do not qualify. This is a significant advantage.
- Stamp duty concessions: NSW first home buyers are exempt from stamp duty on new homes up to $800,000 and pay reduced duty up to $1M.
- Time to save: A 1–3 year construction period gives you time to save additional funds, pay down other debts, or improve your income before settlement.
- First Home Guarantee: The First Home Guarantee applies to OTP purchases — you can use a 5% deposit with no LMI on new properties up to $1.5M in Sydney.
How to Protect Yourself When Buying OTP
Key protective measures for OTP buyers:
- Get independent legal advice: Have a solicitor review the contract before exchange — particularly the sunset clause provisions (the date by which the developer must complete the project or either party can rescind) and any substitution clauses that allow the developer to change the specifications.
- Use a broker experienced in OTP finance: Not all brokers understand the valuation risks and lender restrictions on OTP purchases. An experienced broker will set realistic expectations and identify which lenders are most favourable for the specific building and postcode.
- Stress-test your finances for a valuation gap: Assume the property could value at 5–10% below the contract price at settlement. Do you have funds to bridge the gap? If not, how would you fund it?
- Monitor the developer: Check in with the developer/selling agent periodically. Signs of financial difficulty (prolonged delays, contractor changes, vague settlement timelines) should prompt you to speak with your broker and solicitor.

You exchange contracts and pay a 10% deposit at the time of purchase. Settlement — when the balance is paid and you take ownership — occurs when the building is completed, typically 1–3 years later. Lenders provide pre-approval at exchange but issue formal approval only at settlement, including a fresh valuation. The risk is that the valuation at settlement may be lower than the contract price.
If property values fall between when you exchange contracts (and set the price) and when settlement occurs (when the building is complete), the lender will value the property at its current market value — which may be lower than your contract price. You must fund the difference between the loan the bank will provide (based on the lower valuation) and your contract price minus the initial deposit.
Yes. Off-the-plan new builds qualify for the First Home Guarantee, allowing eligible first home buyers to purchase with a 5% deposit and no LMI on properties up to $1.5M in Greater Sydney.
Most mainstream lenders require a minimum internal area of 50sqm (excluding balcony, car space, and storage). Some lenders require 40sqm as the absolute minimum. Very small OTP units below 40sqm are generally unfinanceable with mainstream lenders. Your broker will check lender policy on specific building and unit size before you commit.
You should obtain pre-approval at the time of exchange (signing contracts), even though formal approval is only granted at settlement. Check in with your broker 3–4 months before the expected settlement date to confirm lender policies haven't changed and to begin the formal approval process. Don't leave finance arrangements until the last minute.
