Investing in Poipu, HI — Market Analysis
Poipu sits at the luxury end of the Hawaii investment market, with a median home price around $1,400,000. Poipu is a resort and vacation-rental market. The long-term rent number here rarely tells the real story — the investment case is usually built on nightly revenue, and lenders that accept documented short-term rental income underwrite these deals very differently from lenders that do not.
Buying a rental property in Poipu on a DSCR loan means putting a minimum of $280,000 down (20% of purchase price), leaving a loan amount of $1,120,000 at 80% LTV. At current DSCR investor pricing near 7.50%, principal and interest on that loan runs about $7,831 per month. Add Kauai County property taxes of roughly $338/month, landlord insurance of about $1,073/month, and an HOA/master-association allowance of $320/month, and your all-in PITIA lands near $9,563/month. That PITIA figure — not the P&I — is what the lender divides your rent into.
A long-term lease in Poipu should generate roughly $4,000/month in gross rent. Against a PITIA of $9,563, that produces an estimated DSCR ratio of 0.42x. That is well below the 1.0 threshold on a long-term lease, which is typical for a market at this price point. Financing here generally works one of three ways — a larger down payment, a no-ratio DSCR product, or qualifying on short-term rental revenue instead of long-term rent.
If you intend to operate the property as a short-term rental, estimated gross nightly revenue in Poipu is around $8,600/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 $6,192/month, or a DSCR ratio of 0.65x. Even on short-term revenue this is a tight file, so plan on a larger down payment or a no-ratio structure.
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 Poipu specifically, effective property tax on investment property runs around 0.29% of value annually — about $4,060 a year at the median price — and landlord insurance near $12,880 a year.
On return metrics, Poipu pencils to an estimated cap rate of 2.13% using a 62% NOI margin, and a gross rent multiplier of 29.2. Monthly cash flow on a long-term lease at 20% down is estimated at $5,563 negative. Negative cash flow at 20% down is common in appreciation-led markets; investors here typically increase the down payment, buy below median, add a unit, or run the property short-term to close the gap.
