Hawaiʻi cap rates

A five-sale median cannot price every island

Hawaii Multifamily Advisor reports a 4.70% median cap for five July 2026 apartment-property trades in its 5+ unit coverage. The September active-listing median was 4.18%, from a different cohort. The 52-basis-point difference is a pricing reference, not a matched bid–ask discount or evidence that every island trades at the same yield.

Hawaiʻi multifamily cap evidence and operating comparisons

The useful benchmark is one that matches the property’s geography, income basis, condition and buyer pool. Cap rate is annual net operating income (NOI) divided by price, before financing. A county gross rent-to-value index is a different measure.

A total sale count is not necessarily the number of sales with disclosed caps. Published averages, medians, asking yields, modeled references and professional surveys are different statistics. Undisclosed weighting or NOI conventions prevent a reliable statewide average and like-for-like appraisal. Two publishers using the same provider do not create independent confirmation.

What changes the underwriting locally?

Use local operating evidence to decide which property assumption needs verification next. Each interpretation below is conditional editorial analysis, not a measured cap-rate forecast.

Urban Honolulu and Makiki: a transaction is an input, not a neighborhood curve

Reported evidence: The July update identifies a 23-unit Makiki transaction among only five total monthly trades. It does not establish a Makiki median cap. Hawaii Multifamily Advisor September update

Local underwriting mechanism: One large transaction can dominate monthly dollar volume without dominating the unweighted median. Building tenure, utilities and work needs can separate two nearby walk-ups more than their street names suggest.

RentalCalcs interpretation: The July median supports a starting conversation about actual trades. It cannot prove broad compression from the earlier quarterly median because the period and cohort change.

What would change the view, and what to obtain?

Contrary evidence: A matched set of arm’s-length sales with consistent trailing NOI could support a trend; until then the direction remains uncertain.

Property decision: Obtain fee-simple versus leasehold terms, remaining land-lease obligations where applicable, utility responsibility and buyer-adjusted sale NOI. A lower yield is not justified solely by the Makiki address.

Hilo and Hawaiʻi Island: lower housing rent does not prove a higher apartment cap

Reported evidence: UHERO’s 2024 ACS rent reference is $1,510 for Hawaiʻi County, compared with Honolulu’s $2,083. These are housing-stock medians, not 2026 apartment quotes. UHERO Hawaiʻi Housing Factbook 2026

Local underwriting mechanism: A lower rent base changes the cash available for insurance, utilities and replacements. It does not provide the price denominator or a sale-cap sample. Hilo and Kona also need their own rent and property comparisons.

RentalCalcs interpretation: Use a property-specific margin test, not an assumed Neighbor Island yield premium. Income resilience must be established before choosing the cap.

What would change the view, and what to obtain?

Contrary evidence: A clean, locally matched sale set and supported renewal collections could justify pricing that the broad housing medians alone cannot explain.

Property decision: Verify the subject’s county parcel classification, hazard/coverage terms and actual competing long-term leases. Do not import Honolulu taxes, operating costs or July sale yields.

Maui and Kauaʻi: establish the permitted income model first

Reported evidence: UHERO discusses major housing-cost, insurance and policy pressures, including Maui vacation-rental changes. No matching conventional-apartment island cap series was verified. UHERO Hawaiʻi Housing Factbook 2026

Local underwriting mechanism: Transient use, long-term apartments and condominium rentals have different income calendars and recurring costs. A use or rental-rule change can remove an assumed income stream before any cap-rate assumption becomes relevant.

RentalCalcs interpretation: There is no defensible island-wide compression call in this evidence. Value the permitted operation, then test policy and expense downside.

What would change the view, and what to obtain?

Contrary evidence: Written confirmation of legal use, durable annual leases and a matching sale set would reduce the uncertainty. A tourism headline alone would not.

Property decision: Confirm current county rules and effective dates for the exact parcel and use. Review association budgets, special assessments and insurance where applicable. Never capitalize a peak vacation month as annual apartment NOI.

Supported submarkets and the missing evidence

No island-weighted statewide average, neighborhood cap curve or current matched-series apartment operating survey was established. Hawaiʻi County and Honolulu ACS rent references are older and broader than the sale sample. Maui/Kauaʻi conventional apartment yields remain unverified. The Q1 median’s +59bp move is a cohort comparison, not a repeat-property value loss.

The next evidence request

Before underwriting a property, obtain a current rent roll reconciled to trailing collections, concessions and delinquency; actual operating statements; buyer tax and insurance costs; a capital inspection; and recent closed comps with documented NOI. Record why each comp matches, which costs changed after sale and whether the cap uses trailing or stabilized income.

The Hawaiʻi county directory and Honolulu County cap-rate screening page serve local screening questions. Their modeled housing indexes are not a substitute for the apartment observations here. Do not copy a county index into a building’s appraisal.

Compression, stabilization or expansion?

The broker’s small sale sample shows that deals clear at yields different from active asking inventory. UHERO independently shows why affordability, insurance, fees and supply constraints can pull in different directions. CBRE’s national survey explains capital-market uncertainty, but does not validate an island cap level. Scarcity can support rent while expenses reduce sustainable NOI.

Attributed publisher outlook

The September broker update attributes July pricing partly to sale composition rather than a broad directional move. UHERO’s supply/affordability analysis is not a cap forecast. CBRE’s nationwide unchanged-cap majority should not be treated as a Hawaiʻi probability.

Perspectives: UHERO Hawaiʻi Housing Factbook 2026 · CBRE H1 2026 Cap Rate Survey. Related reports and shared providers are not counted as independent observations.

RentalCalcs base underwriting position: start with unchanged exit yield and verified buyer NOI. This is a conservative scenario choice, not an assertion that the state’s cap rates will stay flat. The three cases identify evidence that can change the choice; no probabilities or basis-point targets are assigned.

Compression

Durable long-term collections and competitive debt attract buyers to scarce, financeable assets.

Watch: Matching sale NOI, actual loan offers and renewal collections.

Invalidation: Insurance, land-lease or association costs rise faster than collectible income.

Underwrite: Keep compression as upside; avoid pricing a perpetual scarcity premium.

Stabilization

Thin sales and selective capital keep observed medians noisy while property income holds.

Watch: Cohort size, tenure, marketing time and buyer-adjusted expenses.

Invalidation: A broad matching sale sample consistently moves after controlling for income basis.

Underwrite: Use an unchanged exit yield with explicit selling costs in the full deal model.

Expansion

Insurance, use uncertainty or financing erodes margins and demands more yield.

Watch: Binding policies, permitted use, association obligations and refinance coverage.

Invalidation: Verified matching sales tighten despite the same fully funded cost exposure.

Underwrite: Test a wider yield plus an income loss; preserve cash for deductible and capital needs.

Short-term policy rates do not equal property borrowing costs. Loan spreads, term, leverage and amortization affect coverage. Better physical occupancy does not guarantee stronger collected NOI; a smaller construction pipeline does not eliminate existing lease-up competition.

Translate income and yield into property value

Value = annual NOI ÷ (cap rate ÷ 100). At constant income, a higher cap means a lower value. A move from 5% to 6% is +100 basis points and reduces value by 16.7%, before debt or sale costs; it is not a 1% value decline.

A Hawaiʻi evidence-to-offer process

  2. Rebuild island-specific expensesInclude GET treatment, insurance and any land-rent or association obligations.

Starting value $2,160,000

Exit value $1,980,000 (-8.3%)

$108,000 starting NOI at 5% → $118,800 exit NOI at 6%. NOI must change by 20.0% to preserve starting value at this exit cap rate.

The illustration uses 20 units at $1,250 monthly scheduled rent, an 8% vacancy/collection loss and independently stated buyer expenses. These are standardized teaching assumptions, not estimates of attainable Hawaiʻi rent, taxes or premiums. The 5% entry cap is a chosen scenario, not an observed statewide recommendation.

Replace the illustrative costs with property evidence

Rental proceeds are subject to Hawaiʻi GET as well as income-tax rules; transient use has separate TAT implications. Obtain a tax professional’s calculation of taxable base, surcharge and any pass-through. Honolulu property classification must be checked on the parcel; Residential A guidance is not a blanket apartment rate. Hawaiʻi Department of Taxation rental guidance

Verify insurance replacement cost, flood/wind terms, deductibles and interruption coverage. For leasehold or condominium interests, reconcile land rent, association charges and special assessments. The illustrative budget assumes fee-simple conventional annual leases and no separate association/land rent; add those obligations when present.

The $12,000 GET allowance is an assumed annual owner cash cost, with no tenant reimbursement in the illustration. It is not a statutory tax computation. Replace it with the actual taxable receipts, applicable surcharge and lease treatment. Income tax is outside NOI; transient TAT is outside this conventional annual-lease example. Check Honolulu parcel classification separately.

Cash-on-cash, before income tax-0.23%
DSCR / debt yield, before reserves1.10× / 8.33%

The assumed loan is not a current quote. For a hypothetical 1.25× minimum DSCR before reserves, the loan ceiling is about $1,139,118 at these terms; actual sizing also depends on LTV, debt yield and lender reserve/NOI definitions. With a full reserve deduction, DSCR becomes 0.98×. Negative cash is displayed as a loss, never hidden.

Yield on cost is separate: a hypothetical 10% higher stabilized NOI of $118,800 on price, closing and initial work of $2,284,800 produces 5.20%. It is not the going-in yield. Carrying costs and overruns would increase that cost basis; the income improvement has not been earned.

How much of the margin survives?

Additional annual coverage and property operating obligations. This adds a hypothetical recurring cost above the budget below; it is not a quote or an observed expense increase.

Buyer NOI $84,000

Value at the fixed 5% assumed cap $1,680,000

Annual cash after debt and reserve -$26,299

DSCR before reserves: 0.85×. Value impact: −$480,000. The loan stays fixed; this is operating stress, not a refinancing calculation.

Before relying on a Hawaiʻi cap rate

What is a good cap rate?

No single yield is defensible for all of Hawaiʻi. Compare matching closed-sale income, buyer expenses and work requirements, then test debt coverage and invested cash. A higher nominal cap may compensate for missing income or capital obligations rather than create a better return.

Can these apartment references price a duplex or another asset class?

There is no automatic transfer. One-to-four-unit rentals can compete with owner-occupants, while office, retail and industrial leases carry different downtime, credit and leasing-capital obligations. Use a matching sale cohort. The single-family analyzer helps build a smaller rental’s own income budget.

How should a buyer verify NOI?

Reconcile a trailing year of collections, free rent, delinquency and reimbursements to the leases and bank-backed operating statements. Replace taxes, insurance and management with buyer costs. Separate recurring repairs, immediate work and reserves. The NOI classification guide explains the expense bridge.

What if the deal depends on subsidized income or a refinance?

Verify the contract, approved rent, tenant portion, inspection and recurring compliance costs. The voucher-income valuation guide explains why a reference schedule is not contracted NOI. Refinance proceeds also depend on lender income, loan terms and payoff; higher appraised value alone does not guarantee available cash.
