Rooftop solar

First Home Owner Grant
FY2026-27$30,000 for new homes priced up to $750,000.
$30,000 for contracts signed on or after 20 November 2023, with no end date. IT DID NOT REVERT TO $15,000: the tier was due to end 30 June 2026 and the 2026-27 Queensland Budget (23 June 2026) continued it for contracts signed from 1 July 2026. This file carried a "due to revert" note until 2026-09-18 — it was never true, and a note predicting a change is not the same as a change. Cap is "less than $750,000" including land and contract variations — less than, not up to. New homes only: "There are no home owner grants for established homes."
Mortgage repayments
10 mortgage brokers are registered in postcode 4810.
Transfer duty at the owner-occupier rate, and it excludes first home buyer concessions — those can cut it substantially or remove it entirely. Excludes legal, inspection and lender fees. Check with Queensland Revenue Office
The First Home Owner Grant applies to newly built homes only, so it isn't available on an established purchase. A first home buyer building or buying new under $750,000 may qualify for $30,000 — see what qualifies with Queensland Revenue Office.
At $1,370,000 this is $620,000 above the $750,000 First Home Owner Grant cap. A first home buyer may qualify for $30,000 on a newly built home — check eligibility with Queensland Revenue Office.
A deposit under 20% usually attracts Lenders Mortgage Insurance, which this doesn't include.
Principal and interest over 30 years, fixed rate. Excludes fees, offset, redraw and LMI. Default rate is the median comparison rate across 1788 advertised products as at 2026-10-27 — indicative only, and not an offer. Your rate depends on the lender, your deposit and your circumstances.
