Hawaii Real Estate Exam: Mastering Investment Property Analysis
Last updated: April 2026
For candidates preparing for the Hawaii real estate licensing exam, understanding how to evaluate income-producing real estate is an absolute necessity. Because Hawaii is a premier global destination with a high density of vacation rentals, commercial spaces, and multi-family units, the exam heavily tests your ability to calculate returns and navigate state-specific tax liabilities. This guide provides a comprehensive overview of investment property analysis, tailored specifically to the rules and regulations enforced by the Hawaii Real Estate Commission under Hawaii Revised Statutes (HRS) Chapter 467.

Core Financial Metrics for Investment Analysis
To accurately advise future clients or answer exam questions, you must master the universal formulas used to determine a property's financial viability. Be prepared to calculate these metrics using provided scenario data on the exam.
Net Operating Income (NOI)
Net Operating Income (NOI) is the foundation of investment analysis. It represents the annual income generated by an income-producing property after deducting all operating expenses, but before deducting debt service (mortgage payments) or income taxes.
- Formula: Gross Operating Income (GOI) - Operating Expenses = NOI
Exam Tip: The exam will frequently try to trick you by including "monthly mortgage payments" or "principal and interest" in a list of expenses. Never subtract debt service when calculating NOI.
Capitalization Rate (Cap Rate)
The Cap Rate expresses the rate of return on a real estate investment property based on the income that the property is expected to generate. It assumes the property is purchased for cash without financing.
- Formula: NOI ÷ Current Market Value (or Purchase Price) = Cap Rate
In Hawaii's high-value market, Cap Rates tend to be lower than the national average. A higher Cap Rate indicates a higher potential return but often comes with higher risk.
Gross Rent Multiplier (GRM)
GRM is a quick, rough-draft metric used to compare properties based solely on their gross rental income, ignoring operating expenses.
- Formula: Property Price ÷ Gross Annual Rental Income = GRM
If a Maui duplex costs $1,200,000 and generates $100,000 in gross annual rent, the GRM is 12. A lower GRM generally indicates a better investment opportunity.
Hawaii-Specific Investment Factors
What makes the Hawaii real estate exam uniquely challenging is the integration of state-specific laws into standard investment math. You must account for Hawaii's unique tax structures and land ownership systems when analyzing a property's cash flow.
General Excise Tax (GET) and Transient Accommodations Tax (TAT)
Unlike most states that have a sales tax, Hawaii assesses a General Excise Tax (GET) on the gross income of businesses, which includes rental income. Landlords must hold a GET license and pay this tax on all collected rents.
- GET Rates: The base state rate is 4%. However, counties can add a surcharge. For example, the rate on Oahu is 4.5%, while Maui, Kauai, and Hawaii Island have their own respective county surcharges.
If the property is rented for less than 180 consecutive days, it is classified as a short-term rental (STR). In this case, the owner must pay the GET plus the Transient Accommodations Tax (TAT).
- TAT Rates: The state TAT is 10.25%, and counties are authorized to levy an additional surcharge (e.g., Oahu adds a 3% surcharge, bringing the total TAT to 13.25%).
Exam Scenario: When calculating the operating expenses for an Airbnb condo in Waikiki, you must deduct roughly 17.75% (4.5% GET + 13.25% TAT) of the gross rental income just to cover state and county taxes!
Fee Simple vs. Leasehold Properties
Hawaii is one of the few states where leasehold ownership is still relatively common, particularly in older Honolulu condominiums. In a leasehold estate, the investor owns the structure but leases the land it sits on.
When analyzing a leasehold investment property, you must factor the monthly lease rent into the operating expenses. Furthermore, you must identify the "renegotiation date" and "expiration date" of the land lease, as these directly impact the property's future value and financing eligibility. A property with a lease expiring in 10 years will have a drastically different Cap Rate and risk profile than a fee simple property.

Practical Scenario: Analyzing a Waikiki Condo
Let’s walk through a realistic exam-style question to put these concepts together.
Scenario: You are evaluating a fee simple short-term rental condo in Waikiki listed at $900,000. It generates $80,000 in gross annual short-term rental income. The annual expenses are as follows:
- HOA Maintenance Fees: $12,000
- Property Management (20% of gross): $16,000
- Property Taxes: $4,000
- GET & TAT (approx. 17.75% of gross): $14,200
- Insurance: $1,500
- Mortgage Payment: $35,000
Step 1: Calculate Total Operating Expenses
Add the HOA, Management, Property Taxes, GET/TAT, and Insurance.
($12,000 + $16,000 + $4,000 + $14,200 + $1,500) = $47,700.
*Remember: Do NOT include the $35,000 mortgage payment!*
Step 2: Calculate NOI
Gross Income ($80,000) - Operating Expenses ($47,700) = $32,300 NOI.
Step 3: Calculate the Cap Rate
NOI ($32,300) ÷ Purchase Price ($900,000) = 0.0358, or a 3.58% Cap Rate.
Exam Preparation Strategies
Because investment property analysis requires memorizing formulas and understanding how local variables (like GET and leasehold terms) affect those formulas, rote memorization isn't enough. You need to practice applying the math.
To master these formulas, we highly recommend using spaced repetition for exam prep. Creating flashcards that force you to recall the difference between GET and TAT, or the formula for NOI, will ensure you don't blank out on test day.
Additionally, remember that real-world investment analysis often requires verifying what you are actually buying. For exam questions dealing with raw land or agricultural investments, understanding Hawaii metes and bounds legal descriptions is vital for confirming property lines. Similarly, if you are analyzing a coastal investment property, you must be aware of Hawaii water rights and riparian law to understand shoreline setbacks and public access requirements, which can severely limit a property's buildable footprint and, consequently, its investment value.
Frequently Asked Questions (FAQ)
Does the Hawaii General Excise Tax (GET) apply to long-term residential rentals?
Yes. Unlike the Transient Accommodations Tax (TAT) which only applies to short-term rentals (less than 180 days), the GET applies to all gross rental income in Hawaii, regardless of whether the lease is for six days, six months, or six years. Landlords must hold a valid GET license.
How does leasehold status affect a property's Net Operating Income (NOI)?
In a leasehold property, the investor must pay lease rent to the landowner. This lease rent is considered a standard operating expense. Therefore, it must be subtracted from the gross operating income, which lowers the overall NOI compared to a similar fee simple property.
Are property management fees considered an operating expense?
Yes. Property management fees, along with maintenance, insurance, property taxes, and utilities paid by the owner, are all considered operating expenses and must be deducted from gross income to determine the NOI.
What is the difference between TAT and GET on the Hawaii exam?
GET (General Excise Tax) is a tax on the gross income of a business and applies to all rentals. TAT (Transient Accommodations Tax) is an additional tax levied specifically on accommodations rented to transients for fewer than 180 consecutive days. Short-term rentals must pay both.
If an exam question asks for the Cap Rate but provides the monthly mortgage payment, what should I do?
Ignore the mortgage payment! Debt service is heavily dependent on the individual investor's financing terms and is never included in the calculation of Net Operating Income (NOI) or the Capitalization Rate.
