What lenders look at in Castle Hill
Castle Hill mixes big family homes with new apartments near the stations. Here's what tends to come up with lenders.
Larger loan amounts
Larger loans get closer scrutiny of income, expenses and existing debts. Some lenders cap their maximum loan-to-value ratio (LVR) on bigger loans, so check how much deposit you'll need early.
New apartments near the metro
Lenders look at the size of the unit and the building. One LMI provider's public guidelines require at least 30 m2 of living area, not counting balconies and car spaces. Valuers also compare a new unit with resales in the same or similar buildings.
Buying off the plan
If you sign a contract years before completion, your finance is assessed when the building is finished. The valuation at that point may differ from the contract price, so leave room in your deposit.
Townhouses and strata
10.9% of homes are townhouses or semis and many sit in strata or community schemes. Read the scheme's records for levies, sinking fund balances and any building defects.
Bushland edges
Parts of Castle Hill back onto Bidjigal Reserve and other bushland. Check the planning certificate for bush fire prone land because it can affect insurance and building costs.
Postcode 2154
Castle Hill has its own postcode, 2154. It isn't on one LMI provider's lists of excluded or single-industry postcodes.
Lender and LMI policies differ between lenders and change often. This is a general guide based on public lender and LMI information checked 3 November 2026. We can check current policy for the property you're looking at before you apply.

- building and pest inspections
- strata or body corporate searches for units and townhouses
- lenders mortgage insurance (LMI) if you borrow more than 80% of the property's value
