Should You Rent Out Your Beach House? The Vacation Rental Math

A Bethany Beach home can gross $40,000+ a summer. It can also eat every dollar of it. Here's the honest math on Delaware beach rentals in 2026.
The pitch is seductive: buy the beach house, rent it all summer, let strangers pay your mortgage. And the gross numbers are real. But 2026 is also a softening market — occupancy and rates both slipped year over year. Here's the full picture.
What beach houses actually rent for
Current Delaware beach listings (fall 2026):
- 3BR cottage near Rehoboth Beach: $3,400–$5,000/week in season
- 4BR Dewey Beach townhouse: $3,600–$4,600/week
- 5BR home, North Shores: ~$6,400/week
- 2BR Rehoboth condo: $1,700–$3,300/week
AirDNA's 2026 market data shows average daily rates of $451 (Bethany), $445 (Rehoboth), and $377 (Lewes), with occupancy around 51–55% — both down from 2025 (occupancy off ~11–12%, rates off ~6–10%). Translation: still strong, but no longer the frenzy of 2021–2023. Price competitively or sit empty.
The revenue math (illustrative)
A well-located 4BR home near Bethany Beach, professionally managed:
- 14 peak weeks × ~$4,000/week = $56,000 gross
- Shoulder season + off-season weekends: +$8,000–$12,000
- Gross: ~$64,000–$68,000
Now the costs:
- Property management (typically 20–30%): −$14,000
- Cleaning turnover: −$4,000
- Extra insurance (short-term rental rider): −$1,500
- Maintenance/repairs (renters are hard on houses): −$5,000
- Utilities (renters + hot tubs = big bills): −$4,000
- Delaware lodging tax compliance: varies
- Net before mortgage: ~$35,000–$40,000
Against a $4,500/month carrying cost ($54,000/year), the rental income offsets most of the ownership cost but rarely covers it fully — unless you bought long ago at a lower price.
What the gurus don't mention
Regulations are tightening. Delaware beach towns have been adding rental licensing, occupancy limits, and enforcement. Check the town-specific rules before you buy — they vary street by street in some places.
Your own use has a cost. Every week you spend there is a $4,000 week you didn't rent. Owners consistently underestimate this.
Wear and tear is real. A rental home needs repainting, re-carpeting, and appliance replacement roughly twice as often as a private home. Budget 1–2% of the home's value annually for rental-grade maintenance.
Taxes cut both ways. Rental income is taxable, but you can deduct expenses — and the 14-day rule (rent 14 days or fewer and the income is tax-free) is a legitimate strategy for owners who mostly self-use.
The bottom line
Buy the beach house because you want the beach house. Treat rental income as a subsidy that covers 50–80% of carrying costs — not as an investment that pays for itself. In a softening market like 2026's, conservative underwriting isn't pessimism. It's how you still own the house in 2030.
