Sydney housing segments are moving differently: how to compare value and affordability

Sydney's housing market is not moving as one uniform block. Recent Cotality analysis shows the upper quartile of Sydney house values more than 10 per cent below its peak, while lower priced homes and units have shown greater resilience. That difference matters when buyers, sellers and borrowers interpret headlines about falling prices.

A softer premium segment does not automatically make every property affordable. Borrowing costs, deposit size, insurance, strata fees, repairs and commuting costs still shape the real household budget. A lower advertised price can be offset by a larger loan or higher ongoing costs.

Compare the segment, not just the suburb

Before making an offer, compare similar properties by type and price range. A detached home, townhouse and apartment can have different buyer demand, supply levels, maintenance obligations and resale conditions even when they sit in the same suburb. Look at recent comparable sales, days on market and the quality of competing listings.

For apartments and townhouses, include strata levies, special levies, sinking-fund plans and building issues in the numbers. For houses, allow for insurance, drainage, roofing, retaining walls and future maintenance. These costs can change the result more than a small movement in the headline price.

What buyers and sellers can do now

Buyers should set a comfortable repayment limit before inspecting homes, then test that limit against a realistic buffer. Sellers should price from current comparable evidence rather than relying on the strongest sale from last year. In either case, a local property professional and a qualified finance or legal adviser can help with decisions that require personal advice.

• Compare like with like across property type and price band.
• Budget for ownership costs beyond the mortgage.
• Use current local evidence before negotiating.
