Buying A Unit Vs House in South West Sydney: Your 2026 Guide

In 2026, South West Sydney offers distinct advantages for both unit and house buyers, with each property type suiting different budgets, financing strategies, and lifestyle goals. Whether you're looking at a Bankstown apartment at $580,000 or exploring houses in Panania - Revesby or Padstow above $1.6 million, the choice affects your deposit requirements, loan structure, and long-term investment outcome significantly.

The financing implications are particularly important in this market. Units in Bankstown and Liverpool sit below the $800,000 stamp duty exemption threshold for first home buyers, while all house prices exceed $1,000,000. This creates meaningfully different entry costs and scheme eligibility between the two property types.

Infinity Mortgage Brokers helps buyers across Bankstown and South West Sydney compare unit and house financing options across 40+ lenders, completely free of charge.

In this guide, we'll walk you through the key differences in affordability, financing options, and market performance to help you make the right choice for your situation.

Which property type gives first home buyers the strongest start?

Units offer the clearest path for first home buyers in South West Sydney in 2026. Bankstown units have a median price of $580,000 with strong growth of +10.48%, while Liverpool units sit at $520,000 with growth of +4.63% as of April 2026. Both are well below the $800,000 stamp duty exemption threshold, meaning eligible first home buyers pay no transfer duty at all.

Houses require a different approach. With all house medians exceeding $1,000,000 across South West Sydney, stamp duty exemptions don't apply. Instead, the First Home Guarantee becomes the primary advantage, allowing 5% deposit purchases up to $1,500,000 without lenders mortgage insurance.

What are the key financing differences between units and houses?

The deposit and initial costs vary significantly. First home buyers purchasing a $580,000 Bankstown unit with the First Home Guarantee need just $29,000 plus costs, with no stamp duty and no LMI. Buying a $1,631,000 house in Padstow requires $81,550 plus costs, with full stamp duty of approximately $64,000 but still no LMI under the guarantee.

Lender assessment is generally the same for both property types, though some lenders apply stricter loan-to-value ratios for units in certain buildings. The key difference is affordability - the lower entry price for units means stronger borrowing capacity goes further.

How to choose between a unit and house in South West Sydney

Step 1: Talk to us

Step 2: Review your financing position

We calculate your maximum borrowing capacity and compare what that means in terms of unit versus house options across South West Sydney, including total upfront costs and ongoing repayments.

Step 3: Confirm scheme eligibility

We verify your eligibility for first home buyer schemes and determine which combination gives you the strongest advantage - stamp duty exemption for units or the First Home Guarantee for either property type.

Step 4: Compare lender policies

We identify which of our 40+ lenders offer the most competitive rates and terms for your chosen property type, as some lenders have specific policies around unit lending or building age requirements.

Step 5: Structure the application

We prepare your loan application with the optimal lender and structure, ensuring you're positioned for quick approval whether you're targeting units or houses.

Step 6: Coordinate settlement

We handle the loan process through to settlement, working with your solicitor and the vendor's team to ensure a smooth outcome regardless of property type.

Common mistakes buyers make when comparing units and houses

The biggest mistake is focusing solely on the purchase price without calculating total upfront costs. A $580,000 unit in Bankstown might require $40,000 to get started, while a $1,390,000 house in Chester Hill could need $130,000 in deposit and stamp duty combined. The all-in cost difference shapes what's actually achievable.

Many buyers also underestimate the impact of strata fees on unit ownership. While houses have maintenance costs, units have quarterly levies that affect serviceability assessment. Some lenders treat strata fees as a monthly commitment when calculating borrowing capacity, which varies between lenders significantly.

Market performance and growth potential comparison

Units and houses in South West Sydney have delivered different growth patterns over the past year. Bankstown units returned +10.48% growth with strong sales volume of 472 transactions, indicating solid demand depth. House growth has been more varied, with standout performers like Panania at +12.90% and Moorebank at +9.08%, but also some flat markets.

From an investment perspective, units typically offer higher rental yields due to the lower purchase price, while houses generally provide stronger capital growth over longer time periods. The Bankstown metro upgrade is expected to benefit both property types, with units potentially seeing stronger rental demand due to improved CBD access, and houses benefiting from the infrastructure-driven capital appreciation.

Frequently Asked Questions

Do lenders treat unit and house applications differently?

Generally no - the same income and serviceability assessment applies to both property types. Some lenders have specific policies around unit lending, particularly for buildings over a certain age or with high investor ratios, but the core approval criteria remain consistent.

Can I use the First Home Guarantee for both units and houses?

Yes - the First Home Guarantee applies to both property types up to the $1,500,000 price cap, which covers the full South West Sydney market. The 5% deposit and no LMI benefit is the same whether you're buying a unit or house.

Which property type is better for first home buyers in 2026?

Units offer lower entry costs and stamp duty exemptions for eligible buyers, while houses provide more space and typically stronger long-term growth. Your best choice depends on your budget, lifestyle priorities, and whether you're buying to live in or as an investment.

How do strata fees affect my borrowing capacity?

Most lenders include quarterly strata fees when assessing your monthly commitments, which can reduce borrowing capacity by approximately $20,000 to $30,000 for every $100 per week in strata costs. The exact impact varies between lenders.

Are there stamp duty savings for units in South West Sydney?

Yes - first home buyers purchasing units priced at or below $800,000 may qualify for the full stamp duty exemption. This applies to median-priced units in Bankstown and Liverpool, but always confirm eligibility with Revenue NSW for your specific purchase price.

Should I use a mortgage broker for unit or house purchases?

A mortgage broker, every time. Lender policies around unit approvals vary significantly, particularly for older buildings or high-density developments. A broker comparison identifies which lenders offer the most competitive terms for your specific property type and situation.

What's the typical deposit difference between units and houses?

With the First Home Guarantee, both require 5% deposit plus costs. The difference is the dollar amount - 5% of a $580,000 unit is $29,000, while 5% of a $1,631,000 house is $81,550. Stamp duty adds another layer for houses but not for eligible unit buyers.

Your Next Steps

Your property choice affects more than just your lifestyle - it shapes your deposit requirements, ongoing costs, and long-term wealth building strategy.
