On Hawaiʻi Island the listing price is often the easy number. Catchment equipment, wastewater conversion, driveway and rock work, insurance questions tied to lava-flow hazard maps, and the last mile from Hilo or Kawaihae change the budget.

Direct answer. Do not treat a Hilo municipal-water house like a Puna catchment lot, and do not treat a lava-zone map as an insurance or lender decision. Pull County of Hawaiʻi records, then replace every calculator default with that property.
Comparable facts
Treat Hilo municipal water, Puna catchment, and lava-zone map research as different jobs.

Open official source ↗Common questions
The listing price can be lower while monthly operations are not. Catchment maintenance, wastewater conversion, insurance questions, long drives, and freight can erase an apparent bargain. Compare true monthly cost for the actual systems on the property.
No. USGS lava-flow hazard information is one research input. Insurers and lenders use their own rules, and those rules change. Ask for written indications before removing contingencies.
No. A documented, maintained system with testing and a shortage plan can be workable. An undocumented tank with no treatment history is a different decision. Inspect the whole water path.
