Home loan considerations in Seaview Downs and Trott Park

Seaview Downs
- Upgraders
- First home buyers
- Downsizers
- No flats were recorded at the 2021 Census and only 32 townhouses, so low-maintenance housing is scarce.
- The suburb is small, with 1,022 occupied dwellings, so comparable sales evidence can be thin.
- Elevated and sloping blocks vary in outlook, usable land and retaining structures, which affects valuation.
- Bushfire hazard mapping may apply near the O'Halloran Hill Recreation Park, which affects insurance.
- Only 11.7 per cent of households with a stated tenure rented, so the tenant pool is very thin for investors.
Trott Park
