Charleston has become one of the most sought-after vacation destinations in the Southeast, regularly topping 'best city in America' lists. The combination of the historic downtown district, Sullivan's Island and Isle of Palms beaches, and a nationally renowned restaurant scene creates STR demand that spans the full calendar year — not just summer months.

Properties in Charleston's STR market typically range from $500K downtown carriage houses to $800K+ beachfront homes on the barrier islands. At a $650K average, cost segregation reclassifies approximately $156K into accelerated MACRS classes, generating about $58K in first-year tax savings. The professionally furnished interiors that Charleston's design-conscious market demands translate directly into high FF&E reclassification.

South Carolina's favorable tax environment (top rate 6.5%) keeps the cost segregation benefit predominantly at the federal level. Charleston STR investors who materially participate in their rental operation — managing bookings, coordinating with local property managers, handling guest communication — can deduct the accelerated depreciation against W-2 income. For high-income professionals buying a vacation home that doubles as an investment, this is the most powerful tax strategy available.

Why Cost Segregation Works for Short-Term Rentals

Short-term rentals contain a higher concentration of depreciable personal property than almost any other residential property type. Furniture, appliances, linens, kitchenware, electronics, decorative fixtures, and specialty items like hot tubs or game room equipment all qualify as 5-year property under the IRS MACRS classification system. This furniture, fixtures, and equipment (FF&E) component typically represents 15-20% of the depreciable basis.

Beyond interior components, site improvements add additional reclassification value. Driveways, walkways, patios, outdoor lighting, fencing, landscaping, and irrigation systems fall into the 15-year MACRS class rather than the default 27.5-year residential schedule. For STR properties with pools, outdoor kitchens, or fire pits, these components can represent a meaningful share of the total reclassified amount.

With 100% bonus depreciation permanently restored under the One Big Beautiful Bill Act (signed July 2025), every dollar reclassified into 5-year, 7-year, or 15-year MACRS classes is deductible in full in the first year. For STR owners who materially participate in their rental operation, these accelerated deductions can offset W-2 and business income — not just passive rental income.

Who This Example Applies To

Airbnb, Vrbo, or short-term rental property owners
Investors who materially participate in their STR operation (100+ hours/year)
Taxpayers in the 32-37% federal bracket (where savings are most significant)
Properties with furniture, appliances, and guest-ready finishes

If your property is a passive investment managed entirely by a third party, the accelerated depreciation may only offset passive income. If your property has minimal furnishings or you plan to sell within 1-2 years, the benefit may be reduced. Actual results vary based on property age, condition, renovations, and local construction costs.

Frequently Asked Questions

What is a cost segregation study? ▼

A cost segregation study is an engineering-based analysis that reclassifies components of your property into shorter IRS depreciation categories (5, 7, and 15 years) instead of the default 27.5 or 39 years. This accelerates your depreciation deductions, reducing your tax bill in the early years of ownership.

Why do Airbnbs get higher cost segregation deductions? ▼

Short-term rentals are typically furnished with furniture, appliances, electronics, linens, kitchenware, and décor — all of which qualify as 5-year personal property under MACRS. This FF&E (furniture, fixtures, and equipment) often represents 15-20% of the property's depreciable basis, significantly increasing the accelerated depreciation amount compared to unfurnished long-term rentals.

Is bonus depreciation available in 2026? ▼

Yes. The One Big Beautiful Bill Act permanently restored 100% bonus depreciation for property placed in service in 2025 and beyond. This means you can deduct the full amount of accelerated depreciation identified in your cost segregation study in year one.
