Many buyers in Myrtle Beach are attracted by the idea of owning a vacation rental that "pays for itself." But calculating true return on investment requires looking beyond gross rental income—and the real numbers often look different than what sellers and listing agents advertise. Here's how to do the math correctly.
Start With Gross Rental Income
Gross rental income is the total revenue collected before expenses. Look for actual income data from the current owner—not projected estimates. Many rental management companies can provide historical performance reports for a specific unit. Be skeptical of income projections based on "potential" rather than documented history.
Subtract All Expenses
True ROI requires accounting for every expense. Common costs include: HOA fees, property management fees (typically 20–35% of gross rental income), property taxes, insurance (HO-6 + flood), utilities not covered by renters, maintenance and repairs, and any platform fees (Airbnb, VRBO, or booking platform commissions). These costs can easily consume 50–60% of gross rental income.
Calculate Net Operating Income (NOI)
Gross Rental Income minus Total Operating Expenses equals your Net Operating Income (NOI). This is the number that tells you how much cash the property actually generates before debt service. If you're financing the purchase, subtract your annual mortgage payment from NOI to get true cash flow.
Calculate Cap Rate and Cash-on-Cash Return
Cap rate = NOI ÷ Purchase Price. This allows you to compare investment properties on an apples-to-apples basis. Cash-on-cash return = Annual Cash Flow ÷ Total Cash Invested (down payment + closing costs). For Myrtle Beach vacation rentals, a cash-on-cash return of 4–8% is generally considered healthy, though it varies significantly by building and location.
Factor in Appreciation and Tax Benefits
Beyond cash flow, vacation rental properties can appreciate in value over time and offer tax deductions including depreciation, mortgage interest, and operating expenses. These benefits can significantly improve your overall return when factored into a long-term hold analysis.

Frequently Asked Questions
How do you calculate the true ROI of a Myrtle Beach vacation rental?
True ROI goes beyond gross rental income. Start with your annual gross rental revenue, then subtract all operating costs: HOA fees, property management (typically 20–30% of gross), utilities, insurance, property taxes, maintenance reserves, and any platform fees. Divide that net income by your total cash invested (down payment plus closing costs and setup expenses) to get your cash-on-cash return. That's the number that tells you how hard your money is actually working.
What expenses do most buyers underestimate for a Myrtle Beach vacation rental?
The biggest surprises tend to be HOA fees (which can run $600–$1,200/month for oceanfront buildings), special assessments, property management commissions, and ongoing maintenance in a saltwater coastal environment. Many buyers focus on the purchase price and nightly rental rate without building in a realistic maintenance reserve of 5–10% of gross revenue. Vacancy costs and platform fees also add up faster than most projections account for.
What gross rental income can I realistically expect from a Myrtle Beach condo?
Gross rental income varies significantly by unit type, building, floor, and view. A well-positioned two-bedroom oceanfront condo in a premium building can gross $40,000–$60,000+ annually. A one-bedroom with an ocean view might generate $25,000–$40,000. Studios and off-beach locations typically produce less, though their lower purchase prices can still yield competitive cap rates. Historical rental data from the building or a local property manager is the most reliable basis for projections.
Does using a property management company affect my rental ROI?
Yes — management commissions typically run 20–30% of gross rental income, which is a meaningful reduction in net returns. However, a good local property manager handles guest communications, maintenance coordination, cleaning schedules, and platform optimization, which can improve occupancy rates and protect your property. Some owners self-manage via Airbnb or VRBO to retain that margin, but this requires active involvement and works better for those who live nearby or are very hands-on.
Is a Myrtle Beach vacation rental still a good investment in 2026?
For well-selected properties in the right buildings, yes. The Grand Strand continues to draw millions of visitors annually, and demand for short-term rentals has remained resilient. The key is doing thorough due diligence: reviewing the building's rental history, understanding HOA rules around short-term rentals, and working with a local agent who can identify properties with proven income track records rather than optimistic projections.
