A practical guide for short-term rental owners in Sussex County and Worcester County

Gross revenue is important, but it does not tell the complete story of a vacation rental property.

A home that produces $75,000 in annual revenue may not be more profitable than a home producing $60,000. The difference may come from cleaning costs, maintenance, owner-use restrictions, high vacancy, lower nightly rates, or expensive operating requirements.

Owners should evaluate performance using several measurements together. This applies to vacation rentals in Rehoboth Beach, Lewes, Dewey Beach, Bethany Beach, Fenwick Island, Ocean View, Millville, Selbyville, Ocean City, West Ocean City, Berlin, Ocean Pines, Showell, Bishopville, and surrounding coastal markets.

1. Gross rental revenue

Gross rental revenue is the income collected from nightly or weekly rent before expenses.

It should be reviewed by:

• Month
• Quarter
• Season
• Property
• Booking channel
• Year over year

Cleaning fees, pet fees, amenity fees, taxes, and other pass-through charges should not automatically be treated as rental income. These amounts may be collected for a specific service or third party and may not represent profit for the owner.

Gross revenue is a starting point—not the final measure of success.

2. Occupancy

Occupancy measures how many available nights were booked.

Formula

Booked nights ÷ available rental nights = occupancy rate

For example:

• 180 booked nights
• 300 available rental nights
• 60% occupancy

Owners should define “available rental nights” clearly. A property may be unavailable because of:

• Owner stays
• Maintenance
• Renovations
• Personal holds
• HOA restrictions
• Minimum-stay requirements
• Calendar restrictions

Owner-use nights should be reviewed separately. Blocking dates for personal use is a valid choice, but those dates reduce the number of nights available to produce rental income.

Occupancy should never be evaluated without reviewing the nightly rate. A property can increase occupancy by lowering prices, but that may reduce total profitability.

3. Average Daily Rate

Average Daily Rate, commonly called ADR, shows the average rental revenue earned for each booked night.

Formula

Rental revenue ÷ booked nights = ADR

For example:

• $54,000 in rental revenue
• 180 booked nights
• $300 ADR

ADR should be reviewed by:

• Weekday versus weekend
• Season
• Holiday period
• Property type
• Location
• Length of stay
• Booking channel

A two-bedroom condominium near the Ocean City Boardwalk should not automatically be compared with a large home in Ocean Pines or a property near Bethany Beach. The homes may serve different guest groups, have different operating costs, and compete in different rental segments.

4. Revenue per available rental night

Revenue per available rental night measures how much rental revenue the property produced across all nights it was available for booking.

Formula

Rental revenue ÷ available rental nights = revenue per available rental night

Example:

• $54,000 in rental revenue
• 300 available rental nights
• $180 per available rental night

This number combines occupancy and nightly rate. It helps show whether the property is earning efficiently across its available calendar.

Ocean City’s official tourism organization identifies occupancy, ADR, and RevPAR as common short-term rental performance measures. For vacation rentals, owners may use “revenue per available rental night” because the property is generally measured by nights rather than hotel rooms. Ocean City tourism performance metrics

5. Net operating revenue

Gross revenue does not equal owner profit.

Owners should subtract property-related operating expenses, including:

• Management fees
• Cleaning costs paid by the owner
• Linen and terry expenses paid by owner or the guest
• Maintenance and repairs
• Supplies
• Utilities
• Pest control
• Insurance
• Local licenses and taxes
• HOA or condominium fees
• Platform or processing fees
• Furniture and equipment replacement
• Emergency service calls

Formula

Gross rental revenue − operating expenses = net operating revenue

The calculation should clearly identify which expenses are paid by the guest, which are paid by the owner, and which are deducted before owner distribution.

6. Cleaning cost per reservation

Cleaning is both a guest-experience expense and an operating cost.

Owners should monitor:

• Cleaning cost per turnover
• Linen and terry cost
• Supply cost
• Number of turnovers
• Back-to-back reservation frequency
• Special-cleaning charges
• Deep-cleaning requirements

A property with frequent short stays may produce strong occupancy but require more turnovers. That can increase cleaning, linen, inspection, and maintenance costs.

The goal is not simply to book more nights. The goal is to produce profitable reservations while keeping the home properly prepared.

7. Maintenance and replacement costs

Maintenance should be reviewed by property and by category.

Track:

• Routine repairs
• Emergency repairs
• Appliance replacement
• HVAC service
• Plumbing issues
• Door and lock repairs
• Furniture replacement
• Exterior maintenance
• Guest-caused damage
• Preventive maintenance

A property may appear profitable until several major repairs are included. Owners should review both actual expenses and expected replacement needs.

A reserve for future repairs can help prevent one major expense from distorting the property’s performance for an entire year.

8. Booking lead time

Booking lead time measures how far in advance guests reserve the property.

Formula

Reservation date − arrival date = booking lead time

Lead time can help owners understand:

• When guests begin booking peak dates
• Whether the property depends on last-minute reservations
• How far ahead holiday periods are being reserved
• When pricing should be reviewed
• Whether calendar restrictions are limiting demand

Lead-time patterns should be reviewed by season and market. A property in Ocean City may have a different booking pattern from a property in Lewes, Selbyville, Berlin, or Ocean Pines.

9. Cancellation rate

Cancellations affect more than revenue. They can create vacant dates, additional administrative work, and pricing challenges.

Owners should track:

• Number of cancelled reservations
• Cancellation percentage
• Revenue lost
• Whether cancelled dates were rebooked
• Time between cancellation and arrival
• Cancellation reasons
• Booking platform involved

Formula

Cancelled reservations ÷ total reservations = cancellation rate

A single cancellation should not automatically indicate a problem. However, repeated cancellations may require a review of pricing, listing accuracy, guest screening, cancellation terms, or booking-channel performance.

10. Owner-use restrictions

Owner use is an important part of vacation-home ownership, but blocked dates affect performance.

Owners should distinguish between:

• Nights booked by guests
• Nights used by the owner
• Nights blocked for maintenance
• Nights blocked because of personal preference
• Nights unavailable because of minimum-stay restrictions
• Nights lost because of calendar gaps

A property with fewer available nights may have a strong occupancy percentage while producing less total revenue. Both occupancy and total revenue should be reviewed together.

11. Calendar restrictions and minimum stays

Calendar rules can affect revenue performance.

Examples include:

• Saturday-to-Saturday requirements
• Six- or seven-night minimum stays
• Limited check-in days
• Blocked gap nights
• HOA restrictions
• Seasonal availability limits

Restrictions may be required by a town, HOA, condominium association, or owner preference. However, owners should understand how those restrictions affect the number of bookable nights and the property’s ability to fill calendar gaps.

A calendar should be reviewed for both compliance and revenue efficiency.

12. Guest experience and property condition

Financial performance should be reviewed alongside the guest experience.

Owners should monitor:

• Guest review ratings
• Repeated complaints
• Cleanliness concerns
• Check-in problems
• Missing or damaged items
• Maintenance-related complaints
• Response times
• Rebooking or referral activity

A property may generate strong short-term revenue while creating avoidable damage, poor reviews, or excessive staff workload. Those issues can affect future demand and long-term asset condition.

A simple monthly performance review

Blue Heron recommends reviewing each property monthly using the following categories:

The most important question

The most useful question is not:

“How much money did the property make?”

The better question is:

“How much net income did the property produce after operating costs, while protecting the home and maintaining a strong guest experience?”

Public tourism data can help provide general market context. Delaware and Maryland both publish tourism research, but statewide or regional visitor statistics should not be treated as a substitute for property-level performance data. Owners should rely on the actual reservation calendar, revenue statements, expenses, restrictions, and condition of their specific home.
