Cost Segregation in Myrtle Beach: Condo-Hotel Units and Beach Houses

Two owner types, one county

Myrtle Beach sits in Horry County, South Carolina, and the rental market there splits cleanly into two structures. One is the high-rise condo-hotel unit, a single unit inside a tower that runs a resort-style rental program with a front desk, housekeeping, and a management contract. The other is the detached beach house, rented directly by the owner or through a local property manager on a weekly basis. Both draw from the same drive-to feeder markets, Charlotte and Raleigh are a few hours west, with Columbia closer still.

Cost segregation applies to both, and the underlying mechanics never change: a study reclassifies part of the building's basis out of the standard depreciation schedule and into faster schedules that are eligible for bonus depreciation. What changes between the two owner types is not the depreciation math. It is how each one approaches the passive activity rules that decide whether the resulting losses can offset other income.

Condo-hotel units: the rental program changes the participation test, not the depreciation

A unit inside a branded or resort-style rental program is still real property the owner holds, and it still qualifies for cost segregation on the interior components the owner actually owns: cabinetry, flooring, window treatments, appliances, and unit-level fixtures. What the program changes is section 469, the passive activity rule that applies to rental losses by default. The short-term rental exception under Reg. 1.469-1T(e)(3)(ii) turns off passive treatment when the average guest stay is 7 days or less, but the owner then needs material participation for any resulting losses to offset other income.

The common material participation tests are 500-plus hours, substantially all of the participation, or 100-plus hours and more than any other individual. That third test counts everyone who works the unit, including front desk staff, housekeeping, and a program's on-site management. An owner who hands a unit to a full-service rental program and does none of the day-to-day work is describing a fact pattern where the hours worked by that program's staff count against the owner in that comparison. Whether a specific owner's hours clear the test is a question for that owner's CPA. The depreciation study and the participation test are two separate questions, and a study is worth running regardless of how the second one resolves, since the deductions still exist on the return.

Detached beach houses: the weekly-turnover math

A detached beach house on a Saturday-to-Saturday weekly rental calendar is the classic case for the 7-day average stay test. A full calendar of exactly 7-night stays averages to a 7-day stay, at the line the STR exception draws. Any mix of longer off-season stays, monthly winter rentals, or extended-stay bookings pulls that average upward, and once the average crosses 7 days the property falls back under ordinary rental activity rules. An owner tracking a Myrtle Beach house's booking calendar is tracking exactly the number this test asks about.

Personal use matters here too. Section 280A limits deductions once personal use exceeds the greater of 14 days or 10% of rental days in a year, a threshold worth watching for an owner who also uses the house for a summer week with family. None of this changes what a cost segregation study finds in the building. It changes which owner gets to use the losses the study accelerates.

What gets reclassified in a Horry County beach property

• 5-year property: carpet and most flooring, cabinetry, appliances, window treatments, decorative and certain accent lighting.
• 7-year property: certain furniture and freestanding fixtures.
• 15-year land improvements: elevated decking, exterior stairs, outdoor showers, pool decking, driveways, and site lighting.
• Stays 39- or 27.5-year: the structural shell, the elevated pilings or foundation system, and central HVAC, since HVAC and roof structure are structural components, a point worth correcting since they are a common misconception.

A condo-hotel unit's study is scoped to what the owner actually owns, typically the interior, since common areas like the lobby, pool deck, and elevators usually belong to the association or the operator, not the individual unit owner. A detached house's study covers the whole structure and the land improvements around it. That scope difference is the main line-item difference between the two studies, not the depreciation rules themselves.

What the numbers look like on a comparable building

On a mid-rise commercial building, a recent engineered study on a mid-rise office produced $479,220 in first-year deductions against a $2,971,345 building basis, for a $12,000 fee, a 39.9-to-1 ratio. A condo-hotel tower is a residential-use building rather than commercial, but the scale comparison holds: a larger building with more unit-level finish work tends to carry more reclassifiable basis. On the residential side, a delivered study on a single-family rental in Montgomery County, Pennsylvania, 4,946 square feet with a $1,040,000 basis, identified $160,242 in accelerated basis and an estimated $174,905 in first-year depreciation for a $1,295 fee, roughly 135 to 1. A detached beach house sits closer to that second case in scale and structure.

Getting a number for your Myrtle Beach property

Every study is custom-priced to the specific unit or house, engineering scope scales with the property, not a flat rate card. A free Preliminary Benefit Estimate models the likely first-year acceleration before any commitment, through the 60-second qualifier at /qualify. Reports run about 4 to 6 weeks during tax season, faster in January and February, and for a property owned for years, the study is claimed through Form 3115 with a section 481(a) catch-up, described in more detail in the look-back study guide, with no amended returns required. If a roof or HVAC system in a Myrtle Beach unit or house gets replaced, partial asset disposition is the mechanic that writes off what remains of the old component, but only in the year of the replacement.

Frequently asked questions

Do condo-hotel units inside a resort rental program qualify for cost segregation?

Yes, on the components the unit owner actually owns, typically interior finishes and fixtures. Common-area assets like the lobby, elevators, and pool deck usually belong to the association or operator, not the unit owner, so the study is scoped to the unit itself.

Does a Myrtle Beach beach house need a site visit for the study?

No. For short-term rental properties, listing photos from Airbnb or VRBO feed the component classification directly, so there is no owner homework and no scheduled site visit required, whether the property is a detached house or a condo-hotel unit.

How does a rental program's staff affect the passive loss test?

The 100-hour material participation test compares the owner's hours to everyone else who works the property, including a rental program's front desk and housekeeping staff. That comparison is separate from whether the depreciation study itself applies, which it does regardless.

What is different about studying a condo-hotel tower versus a full house?

Scope. A tower unit's study generally covers only the interior components the owner holds title to. A detached house's study covers the full structure plus site improvements like decking, driveways, and outdoor showers around it.

How long does a Myrtle Beach cost segregation study take?

Typically 4 to 6 weeks during the main tax season, often 2 to 3 weeks in January and February. Turnaround depends on the property's size and how quickly listing photos or plans are available.
