Estimating Short-Term Rental Income On Oak Island

Thinking about buying a beach home on Oak Island and renting it when you are not there? You are smart to ask how to estimate income before you buy. With strong summer demand and quieter winters, your numbers will look very different month to month. In this guide, you will learn a simple, repeatable way to forecast both gross and net income for an Oak Island short-term rental, plus what to check for compliance and how to fine-tune results. Let’s dive in.

Understand Oak Island demand and seasonality

Oak Island attracts leisure travelers for beaches, boating, and easy access to regional attractions. Repeat guests and second-home visitors are common, which supports steady summer bookings. Proximity to public beach access points often boosts both rates and occupancy.

Peak season runs from roughly May through September, when both ADR and occupancy trend highest. Spring and fall shoulder months, especially April and October, produce stronger weekends and holidays. Late fall through winter, from November to March, is typically the off season with lower occupancy and lower ADR.

What drives your gross revenue

Gross revenue is a function of ADR and occupancy, and both depend on the property and the calendar. Bedrooms and sleeping capacity set your core pricing tier, with clear steps between 2-bedroom, 3-bedroom, and 4-plus-bedroom homes. A short walk to the beach, private parking, ocean views, and pet-friendly policies can lift both rates and booking conversion.

Interior condition and presentation matter. Updated finishes, strong photography, and a complete amenity list help you justify higher ADR and win more bookings. Review volume and rating also influence performance. Listings with more and better reviews tend to achieve higher occupancy and can command a premium.

Build a monthly revenue model

You will get the most accurate forecast when you model revenue by month instead of using a single annual average. Use nearby comps with similar bedroom count and distance to the beach.

Step A: Gather local comps and inputs

Collect 6 to 12 comparable rentals on Oak Island organized by bedroom count and proximity bands such as oceanfront, under half a mile, half to one mile, and over one mile. For each, document monthly ADR and occupancy if available, advertised cleaning fees, and typical minimum stays. Ask local property managers for fee schedules and cleaning costs, and note any HOA rules, taxes, and utilities that apply.

Good data sources include STR analytics platforms for ADR and occupancy trends, live listings on major marketplaces for rates and fees, local managers for operations detail, and official town, county, and state sites for licensing and tax guidance.

Step B: Calculate monthly gross

For each month m:

• ADR_m = median ADR from your comp set for that month.
• OccupancyRate_m = modeled occupancy for that month.
• Nights_m = calendar nights in month m.
• GrossRevenue_m = ADR_m × Nights_m × OccupancyRate_m.

Then sum all months:

• Annual Gross Revenue = Σ GrossRevenue_m.

If you cannot get full monthly data, use peak, shoulder, and off-season bands to estimate, but expect less precision. When you see wide weekday versus weekend spreads, apply separate ADRs for each and weight by day count.

Don’t forget the expenses

Your net income depends on all operating costs, not just management. Some costs scale with bookings and others are fixed regardless of occupancy.

Management and pricing strategy

Full-service management commonly uses a percentage of rental revenue, often in the mid-teens to mid-twenties, sometimes paired with fixed fees. Many managers use dynamic pricing tools that adjust nightly rates based on demand, events, and supply. Compare unmanaged versus managed scenarios because professional management can increase both ADR and occupancy.

Cleaning and turnover

Cleaning is often charged to guests, but you will still pay for vacancy turns, deep cleans, and linen replacement. Estimate cleaning cost per stay × number of stays per year, then add a buffer for occasional extras. Minimum stay rules in peak months, such as three to seven nights, can reduce turnover costs and lift per-stay revenue.

Fixed and variable costs

Include utilities like electric, water, internet, and streaming. Add trash service, landscaping, and routine maintenance. Insurance should be a short-term rental policy, which is typically higher than a standard homeowner policy. Do not forget property taxes and any HOA dues. A practical approach is to reserve 5 to 10 percent of gross revenue for maintenance and set aside a separate capital reserve for furniture and appliance replacement.

Turn your gross into net

• Operating Expenses = ManagementFee% × Gross + Cleaning + Utilities + Insurance + Property Taxes + HOA + MaintenanceReserve + CapExReserve + Marketing + Licensing/Accounting.
• Net Operating Income (NOI) = Gross − Operating Expenses.
• Cash Flow to Owner = NOI − Debt Service (if financed).
• Cash-on-Cash Return = Cash Flow ÷ Initial Cash Invested.

Compliance, taxes, and insurance

Before finalizing pro formas, confirm current local rules and tax requirements. Check the Town of Oak Island ordinance for any licensing or registration requirements, occupancy limits, safety equipment, parking, and noise rules. Review Brunswick County transient occupancy tax registration and remittance details, and verify how North Carolina sales and use tax applies to short-term stays.

Model occupancy and sales taxes as pass-through items if your platform or manager collects them, or include them as an owner expense if you are responsible for remittance. HOAs can limit or prohibit short-term rentals or set minimum stays, so verify HOA rules early. Secure a short-term rental specific insurance policy because standard homeowner coverage often excludes STR activity.

Scenario testing and sensitivity

Build three scenarios so you can see how changes in ADR and occupancy affect returns.

• Conservative: reduce ADR by 10 to 20 percent and occupancy by 5 to 15 percent to account for new supply or softer demand.
• Base: use your comp-derived monthly ADRs and occupancies.
• Optimistic: increase ADR by 10 to 20 percent and occupancy by 5 to 10 percent to reflect superior amenities, ocean views, or professional management and pricing.

For each scenario, recalculate Gross, Operating Expenses, NOI, and Cash Flow. This helps you gauge your risk tolerance and set realistic expectations.

Operational levers that lift results

High-quality photography, prompt guest messaging, and detailed amenity listings improve booking conversion and reviews. Early-stage listings may need lower intro pricing or promotions to build review count and momentum. Consider adding high-impact amenities like an updated kitchen, outdoor shower, or workspace-friendly Wi‑Fi if your comp set shows a rate premium for them.

Location details matter on Oak Island. A short, safe walk to a public beach access, assigned parking, and ocean views can support higher ADR. If your property is farther from the beach, highlight strengths like larger bedrooms, family-friendly layouts, or pet-friendly policies to protect occupancy.

A practical worksheet you can use

Use these fields to build your pro forma. Replace placeholders with your own data.

• Property basics: bedrooms, baths, property type, distance to beach (minutes walking or miles driving).
• Monthly ADRs: ADR_Jan, ADR_Feb, … ADR_Dec.
• Monthly occupancies: Occ_Jan, Occ_Feb, … Occ_Dec.
• Gross revenue by month: Gross_m = ADR_m × Nights_m × Occ_m; Annual Gross = Σ Gross_m.
• Management fee: Mgmt% × Gross, or flat fees if applicable.
• Cleaning: CleaningPerStay × StaysPerYear + deep cleans and linen.
• Fixed costs: Utilities, Internet/TV, Trash, Landscaping, Insurance, Property Taxes, HOA.
• Reserves: MaintenanceReserve = 5–10% of Gross; CapExReserve = set per bedroom or percent of Gross.
• Marketing and platform fees: if you list yourself and they are not included in management.
• Licensing and accounting: local registrations and professional services.
• Taxes: confirm transient occupancy and state sales tax collection and remittance.
• Financing: loan amount, rate, term, annual debt service.
