The Castle Hill Property Market in 2026
Castle Hill's current sales data reflects a high-value house market alongside a lower-priced unit segment that has recorded stronger recent growth. The suburb's housing stock remains weighted towards separate houses, while Census data also highlights the prevalence of larger dwellings.
Established House Market
From September 2025 to August 2026, Castle Hill houses recorded an overall median sale price of $2.55 million, following growth of 1.6% from the preceding 12 months. There were 369 house sales over the period, and the median time on the market was 31 days. Two-bedroom houses recorded a $3,502,875 median, although this figure was based on only three sales. Three-bedroom houses had a median of $1.975 million and four-bedroom houses $2.4 million.
Growing Unit Market
Castle Hill units recorded an overall median sale price of $1.086 million for September 2025 to August 2026, up 12% from the preceding 12 months. There were 252 unit sales, with a median time on the market of 39 days. One-bedroom units had a $680,000 median, two-bedroom units $941,000 and three-bedroom units $1.28 million.
Detached-House Dominance
According to the 2021 Census, separate houses represented 73.7% of Castle Hill's occupied private dwellings. Flats and apartments accounted for 15.3%, while semi-detached, row or terrace houses, townhouses and similar dwellings made up 10.9%. Larger homes were also prominent, with 59.9% of occupied private dwellings having four or more bedrooms.
Metro-Served Strategic Centre
Castle Hill Station is served by the M1 Metro North West & Bankstown Line, with numerous bus routes also serving the station. The Hills Shire Council finalised the Castle Hill Precinct Plan in 2024, establishing a framework for additional housing capacity, employment opportunities and a broader mix of uses within the strategic centre.
What This Means for Your Loan
Castle Hill's local housing data raises several practical considerations for buyers, particularly because larger detached homes form most of the housing stock while units occupy a considerably lower price bracket. These characteristics can affect the amount of finance required and the type of property a buyer may pursue.
Allowing for Higher House Values
Castle Hill's $2.55 million overall house median is more than twice the $1.086 million unit median. Purchases at these different price levels can involve substantially different loan amounts and upfront funding needs, although the requirements for a particular transaction will depend on its purchase price, your available funds, associated costs and financing arrangements.
Considering Larger Family Homes
Nearly 60% of Castle Hill's occupied private dwellings had four or more bedrooms at the 2021 Census, while separate houses accounted for almost three-quarters of the suburb's occupied housing. For buyers targeting a larger home, the required borrowing needs to be considered in conjunction with income, existing financial commitments and the deposit available for the transaction.
Checking Lower-Priced Alternatives
Castle Hill's unit market provides a markedly lower overall median price than its house market, with current one- to three-bedroom unit medians ranging from $680,000 to $1.28 million. Apartments can therefore represent a lower-priced segment of the local market, although any property offered as security will still need to meet the chosen lender's requirements.
Considering First Home Buyer Duty Relief
Eligible first home buyers purchasing in Castle Hill may qualify for the NSW First Home Buyers Assistance Scheme. Under the current thresholds, the Scheme provides a full transfer-duty exemption where the dutiable amount of a new or existing home is $800,000 or less and a concessional rate where the dutiable amount is above $800,000 but below $1 million. Castle Hill's current one-bedroom unit median is below the exemption threshold, and its two-bedroom unit median is within the concession range, but these suburb medians do not determine eligibility for an individual transaction. The buyer and property must satisfy the Scheme's applicable requirements.
Home Loans for Castle Hill Buyers
The types of finance relevant to a Castle Hill purchase can depend on the purpose of the property, the way the buyer plans to fund it and the way their income is documented. As a mortgage broker in Castle Hill, DIY Lending arranges several loan types, including the following:
Owner-Occupier Home Loans
Eligible buyers purchasing a Castle Hill property as their residence can consider home loans with fixed or variable rates and a range of repayment structures and features. The products available will depend on the borrower's financial circumstances, required loan and property involved.
Commercial Property Loans
Commercial property finance can be used to purchase Castle Hill premises for business or as an investment. Loan structure and pricing can depend on factors such as the amount borrowed, business background, risk profile and security offered.
Guarantor Loans
For an eligible purchaser, a family member may be able to provide equity in their property as additional security for the home loan. Depending on the lender and arrangement, a guarantor loan can reduce the buyer's deposit requirement and may avoid Lenders Mortgage Insurance. Both borrower and guarantor should understand the financial commitments and risks involved before entering into the arrangement.
Construction Loans
Buyers planning to build a new home or undertake a major renovation can use construction finance that releases approved funds progressively as work reaches specified stages. DIY Lending can arrange construction loans and help borrowers understand lender requirements and progress-payment arrangements.
Low Doc Loans
Self-employed buyers who do not have the standard income documents generally required for a home loan may be able to consider a low doc loan. Depending on the lender, income may instead be supported by alternative documentation such as business activity statements, business bank statements or an accountant's declaration.
