Investing in Captain Cook, HI — Market Analysis
Captain Cook prices in the middle of the Hawaii market, with a median home price around $600,000. Captain Cook is a smaller Hawaii market. Entry prices are low and gross rent-to-price ratios are among the best in the state, but appraisers have fewer rent comps to work with, and a single vacancy is a much larger share of annual income than it would be in a metro.
Buying a rental property in Captain Cook on a DSCR loan means putting a minimum of $120,000 down (20% of purchase price), leaving a loan amount of $480,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $3,356 per month. Add Hawaii County property taxes of roughly $145/month and landlord insurance of about $240/month, and your all-in PITIA lands near $3,741/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Captain Cook should generate roughly $3,875/month in gross rent. Against a PITIA of $3,741, that produces an estimated DSCR ratio of 1.04x. That clears the standard 1.0 minimum, which is the threshold most DSCR shelves require for their base pricing. There's not much cushion, so a tax reassessment or an insurance increase could push the file into a lower tier — worth stress-testing before you write the offer.
If you intend to operate the property as a short-term rental, estimated gross nightly revenue in Captain Cook is around $8,325/month across a full year. Lenders do not credit gross STR revenue dollar-for-dollar — they typically haircut it 25%–30% for vacancy, cleaning, platform fees, and management. Applying a 28% haircut gives an effective $5,994/month, or a DSCR ratio of 1.60x. On a short-term rental basis the math changes substantially and the deal underwrites well above the minimum.
Two Hawaii-specific items to build into your model: Hawaii has the lowest effective property tax rate in the nation but the highest entry prices, and counties tax non-owner-occupied and short-term rental property at separate, much higher classifications. Transient vacation rental permits (TVR/NUC) are capped and largely non-transferable outside resort zones — the permit, not the property, is the asset. In Captain Cook specifically, effective property tax on investment property runs around 0.29% of value annually — about $1,740 a year at the median price — and landlord insurance near $2,880 a year.
On return metrics, Captain Cook pencils to an estimated cap rate of 4.81% using a 62% NOI margin, and a gross rent multiplier of 12.9. Monthly cash flow on a long-term lease at 20% down is estimated at $134 positive. A cash-flowing file at 20% down is the exception in most markets right now, and it gives you room to absorb a rate that doesn't come down.
