Engineered Analysis: Small-Scope Restaurant, Nashville TN

Overview

A 4,500 SF QSR (quick-service restaurant) with drive-through, freestanding pad site in Nashville. 2010 construction. Acquired for $1,100,000 in 2024.

The Cost Seg Smart engineered analysis identifies $275,768 in accelerated bucket components (31.3% of the $880,660 depreciable basis after a 19.9% land valuation).

What the analysis identifies

The 4,500 SF property carries the component density typical for a QSR with drive-through. The component inventory pulls the following share into accelerated buckets:

• commercial kitchen equipment (ranges, ovens, walk-ins, fryers, prep tables)
• exhaust hoods, makeup air units, kitchen ventilation, and dedicated kitchen HVAC zones
• bar equipment, refrigeration, ice machines, dishwasher booster heaters, specialty plumbing (grease traps, gas piping)
• decorative interior finishes — booths, banquettes, decorative lighting, specialty flooring
• the parking lot, outdoor patio infrastructure, monument signage, and site lighting

Item-level engineering documentation supports each classification — photographs of mounting details, mechanical schematics for HVAC and plumbing classifications, electrical schedules for dedicated-circuit identification.

Reclass breakdown

Land value (excluded from depreciable basis): $219,340 (19.9% land allocation, Nashville TN market).

Year-1 federal tax savings

Assuming 100% bonus depreciation per the One Big Beautiful Bill Act (OBBBA, 2025), the full accelerated bucket components are deductible in year 1:

• Accelerated bucket total: $275,768
• Federal tax savings at 37% top bracket: $102,034

For a passive investor, the deduction creates a passive loss offsetting passive income. For a taxpayer qualifying as a real estate professional under Section 469(c)(7), the deduction offsets active income — including business operating income from non-real-estate sources.

Methodology applied

The engine applied the following parameters:

• Era profile: 2010 build, finish density and component weights calibrated to construction-era patterns
• Geo factor: 0.98 (Nashville MSA, metro calibrated)
• Component count: 42 distinct line items in the inventory
• Indirect cost multiplier: 1.25 (standard 25% indirect uplift covering soft costs, contingency)
• PPI multiplier: 1.04 (BLS construction cost index applied from build year to acquisition year)
• QC status: PASS (engineered analysis cleared all 16 quality-control checks)

The land valuation used the statistical source. Properties where the county assessor record is within reliability tolerances may produce a different land allocation; the engineered methodology applies the most defensible source available.

Audit considerations specific to this property

1. Kitchen equipment vs structural plumbing: Commercial kitchen equipment is 5-year. The gas piping serving the kitchen is 5-year when dedicated to and removable with the kitchen operation. The audit traces each piping run.

2. Exhaust hoods and makeup air: Kitchen exhaust hoods classify as 5-year personal property. The roof curb and structural penetration the exhaust passes through are 39-year. The split is defended by the mechanical drawings.

3. Decorative vs functional lighting: Pendants over the bar are 5-year decorative. Recessed cans providing general illumination as base electrical are 39-year. The lighting plan and circuit schedule resolve the split.

Return profile

The ROI calculation reflects gross year-1 tax savings against the typical study cost range. Net present value of the strategy depends on hold period (longer holds capture more time value) and recapture treatment at sale.
