Mobile Home Park Cost Segregation on Infrastructure and Land Improvements

The Problem

This investor acquired a 120-pad mobile home park for $2.8 million. The property generated $960,000 in annual revenue from lot rents, with the investor also owning 18 park-owned homes generating additional rental income. The prior accountant allocated the entire $2.8 million purchase price between land and a single 27.5-year residential building category, with $1.1 million allocated to land (non-depreciable) and $1.7 million to improvements on a 27.5-year schedule.

Mobile home parks contain extensive infrastructure that qualifies for shorter recovery periods under cost segregation, including water and sewer systems, electrical distribution, roads, pads, fencing, and site improvements. None of this had been broken out from the 27.5-year category. The park-owned homes were also being depreciated on 27.5-year schedules when they should have been classified as personal property on shorter recovery periods.

AE Tax Strategy

1. Cost Segregation on Park Infrastructure Under IRC §168

We commissioned a detailed engineering-based cost segregation study on the $2.8 million mobile home park. The study reclassified $1,120,000 in infrastructure components to shorter recovery periods: $336,000 to 5-year property (electrical wiring to individual pads, water meter connections, sewer laterals, individually metered utility connections), $224,000 to 7-year property (park signage, playground equipment, laundry facility fixtures, office furnishings), and $560,000 to 15-year property (internal roads, concrete pads, perimeter fencing, retaining walls, stormwater drainage, site grading, community area landscaping). Under current bonus depreciation, $560,000 in 5-year and 7-year property was accelerated to year one, and the 15-year property received bonus treatment as well. First-year acceleration: $412,000. Ongoing annual depreciation savings: $62,000.

2. Park-Owned Home Reclassification Under IRC §168(e)

The 18 park-owned manufactured homes had been classified as 27.5-year residential rental property. Manufactured homes placed on leased pads and not permanently affixed to the land qualify as personal property with a recovery period of 10-15 years depending on classification. We reclassified all 18 homes with a combined basis of $324,000 from 27.5-year property to shorter recovery periods. Homes without permanent foundations were classified as 10-year property. This reclassification generated $118,000 in catch-up depreciation via Form 3115. Ongoing annual savings from shorter recovery: $18,000.

3. Utility Income and Expense Optimization Under IRC §162

We restructured the park's utility billing to implement a ratio utility billing system (RUBS) that allocated water, sewer, and trash costs to tenants. This shifted $72,000 in annual utility costs from the owner to residents while creating legitimate utility income. We also established a management LLC that charged the park a 6% management fee, creating a deductible expense at the park level and allowing the management entity to implement an accountable plan and retirement plan for the investor. Annual tax savings from utility and management optimization: $18,000.

Before & After Comparison

Key Takeaways

• Mobile home parks are one of the most cost-segregation-friendly asset classes because 60-70% of the improvement value consists of infrastructure (roads, pads, utilities, fencing) that qualifies for 5-year, 7-year, or 15-year recovery periods.
• Park-owned manufactured homes that are not permanently affixed to the land qualify as personal property with 10-15 year recovery periods rather than the 27.5-year residential schedule applied to site-built structures.
• Internal roads, concrete pads, utility distribution systems, perimeter fencing, and stormwater infrastructure all qualify as 15-year land improvements eligible for bonus depreciation.
• Ratio utility billing systems (RUBS) shift utility costs to tenants while creating additional deductible management overhead at the entity level.
