Hilo 4plexes: Buy a Fourplex and House Hack in Hilo
Hilo is the Big Island's county seat and its largest community: about 50,404 people, a median household income of $81,779, and a typical home value of $562,242. It is a rainier, greener, less resort-driven Hawaii than the Oahu market — and for a fourplex buyer, a market where the numbers are more forgiving and the buildings need more attention.
Hilo by the Numbers
Hilo, on Hilo Bay on the island of Hawaii, has about 50,404 residents. Hilo is a census-designated place, not an incorporated city; Honolulu is the state's only incorporated city. The Census Bureau publishes no annual Vintage population estimate for this CDP, so the population figure here is the ACS 2024 5-year estimate (table B01003), labeled as such. The median household income is $81,779 and the typical home value is $562,242. All income, rent, and earnings figures below are ACS 2024 5-year estimates, since Hilo is under the 65,000 threshold for one-year releases.
| Population (ACS 2024 5-year estimate) | 50,404 |
|---|---|
| State capital | Honolulu |
| Median household income (ACS 2024 5-year, B19013) | $81,779 |
| Households earning under $50,000 (ACS 2024 5-year, B19001) | 32.0% |
| Households earning $50,000 to $99,999 (ACS 2024 5-year, B19001) | 25.9% |
| Households earning $100,000 to $199,999 (ACS 2024 5-year, B19001) | 28.0% |
| Households earning $200,000 or more (ACS 2024 5-year, B19001) | 14.0% |
| Median gross rent (ACS 2024 5-year, B25064) | $1,427 per month |
| Median earnings, all workers 16 and older (ACS 2024 5-year, B20017) | $42,155 |
| Typical home value (ZHVI, September 2026) | $562,242 |
A year at the $1,427 median gross rent is 3.05% of the $562,242 typical home value — a rough gauge of rent against price, not income. In Hilo the gauge should be read alongside the maintenance reality: heavy rain, termites, and older single-wall and plantation-era construction all add to the cost of keeping a building rentable.

Buying a 4plex in Hilo
Hilo's tenant base runs on the university, the hospital, county government, and the astronomy and agriculture economy around Mauna Kea and Mauna Loa. The University of Hawaii at Hilo and Hawaii Community College bring a student element; the county seat brings year-round government and health-care workers. A building that serves both pools — near the university or the downtown bayfront — fills more steadily than one dependent on either alone.
Condition is the Hilo story. Rain is measured in feet, not inches, on the windward side, so roofs, drainage, ventilation, and termite protection are not cosmetic items — they are the building. Verify the roof age, the drainage away from the foundation, and the termite treatment history, and budget for the wet-climate maintenance that a drier market would never require.
Buyer Help and Loans in Hilo
Hawaii lending, even on the Big Island, involves insurance and appraisal considerations that mainland buyers rarely meet, so choose a lender who has closed in Hilo. Ask which programs on the Loan Types page they close for 2-4 unit owner-occupied purchases in Hawaii, and how they treat older Hilo construction and catchment or cesspool-adjacent systems where they exist.
Compare FHA, conventional, and VA (if eligible) on the same Hilo property at verified rents, and get the insurance quote before you finalize the offer — in a wet, volcanic, and hurricane-exposed market, insurance is a deal term, not a footnote. The Loan Types page gives you the program facts for that comparison.
Living in Hilo
Downtown Hilo, with storefronts along the bayfront streets of the Big Island's county seat.
Hilo offers the owner-occupant Rainbow Falls, the Merrie Monarch Festival, and a bayfront downtown at a price well below Honolulu's — in exchange for rain, vigilance about maintenance, and a smaller, steadier tenant pool. Buy the building you inspected in the rain, not the one you toured in the sun.
