Duplex LTR Owner Gets $144K Year 1 Deduction via Cost Segregation

The Problem

This client purchased a $480,000 duplex in Indianapolis as a long-term rental investment. Each unit rented for $1,750 per month, producing $42,000 in annual gross rental income. After operating expenses of $14,200 (property management, insurance, taxes, maintenance), net operating income was $27,800. The property was being depreciated over the standard 27.5-year residential recovery period, producing $15,270 per year in straight-line depreciation. The client, a W-2 employee earning $290,000, had no ability to use the rental losses against active income because the losses were passive and the client's AGI exceeded the $150,000 threshold for the $25,000 passive loss allowance under IRC §469(i).

The client's spouse was a licensed real estate agent working full-time in residential sales, logging over 1,800 hours per year in real property trades or businesses. Despite clearly qualifying for Real Estate Professional Status under IRC §469(c)(7), the couple's prior CPA had never filed the REPS election or documented the spouse's hours. This meant all rental losses were being suspended indefinitely, and the property's depreciation was producing no current tax benefit whatsoever.

AE Tax Strategy

1. Cost Segregation Study Under IRC §168 for Residential Rental

We commissioned a cost segregation study on the duplex, identifying $144,000 (30% of the $480,000 depreciable basis after a $30,000 land allocation on the $510,000 total cost including closing costs allocated to improvements) in components eligible for reclassification: $72,000 in 5-year property (appliances, carpeting, vinyl flooring, window blinds, light fixtures, cabinetry hardware), $31,000 in 7-year property (laundry equipment, built-in shelving, specialty fixtures), and $41,000 in 15-year property (parking area, sidewalks, fencing, landscaping, exterior lighting). Under 100% bonus depreciation, the entire $144,000 was deductible in Year 1.

2. REPS Election and Material Participation Under IRC §469(c)(7)

We filed the REPS election for the spouse, who met both statutory requirements: (1) more than 750 hours in real property trades or businesses during the tax year (she logged 1,847 hours in her real estate brokerage), and (2) more time spent in real property trades or businesses than in any other trade or business. We then documented her material participation in the rental activity itself using the 500-hour test under Treas. Reg. §1.469-5T(a)(1), logging 520 hours of direct involvement in tenant management, maintenance coordination, bookkeeping, and property inspections for the duplex.

3. Loss Utilization Against W-2 Income

With cost segregation producing $144,000 in bonus depreciation plus $12,200 in standard straight-line depreciation on the remaining components, total Year 1 depreciation was $156,200. Against net operating income of $27,800, the property generated a net loss of $128,400. With REPS qualification and material participation, this loss was non-passive and offset the couple's W-2 income. At their combined marginal rate of 32% federal plus 3.23% Indiana state, the $128,400 loss produced approximately $45,200 in first-year tax savings.

Net Loss Applied to W-2	$0	$128,400	$128,400
First-Year Tax Savings	$5,380	$45,200	$39,820
Total	$15,270	$156,200	$144,000 (Year 1 deduction)

Key Takeaways

• Cost segregation on residential rental properties typically reclassifies 25-35% of the depreciable basis, even on smaller properties like duplexes.
• REPS qualification through a spouse who works in real estate (agent, broker, property manager) is one of the most common and powerful paths to unlocking rental losses against W-2 income.
• The REPS election must be made on a timely filed return (including extensions) — it cannot be made retroactively on amended returns for prior years.
• Even modest rental properties can generate six-figure first-year deductions when cost segregation is combined with REPS and bonus depreciation.
