Mobile home parks and manufactured housing communities are one of the most underrated cost segregation opportunities in residential real estate. The reason is structural: far more of a mobile home park's cost basis sits in short-life assets than in almost any other residential property type. Roads, utility infrastructure, concrete pads, site improvements, and land improvements typically make up 40%–60% of a park's basis — and almost all of it qualifies for 15-year or shorter recovery periods.
This guide walks through why mobile home parks are such strong cost segregation candidates, what specifically gets reclassified, and what the first-year math looks like on a real park.
Why MHPs are different from other rentals
In a typical single-family rental, the building itself (27.5-year property) is where most of the cost basis sits. The short-life opportunity is real, but usually in the 10%–20% range of building basis, because the lot is mostly just land.
Mobile home parks are the opposite. On most parks, the owner isn't selling the homes — they're renting the pads. The value of the park is almost entirely in the land improvements: the roads you drive on, the utility distribution that delivers water, sewer, and power to each pad, the pads themselves, the landscaping, the perimeter fencing, the site lighting, and the common amenities. Those are all 15-year property (or shorter, in some cases) for depreciation purposes.
The 27.5-year "building" on an MHP is often just a small clubhouse, a laundry building, an office, and maintenance structures. The rest is everything you can depreciate fast.
What actually gets reclassified on a mobile home park
Here's the typical breakdown of what a cost segregation study identifies on an MHP:
15-year land improvements (the largest category)
- Internal roads and driveways. Asphalt, concrete, or gravel — all of it.
- Utility distribution. Water mains, sewer laterals, gas lines, electrical distribution, and all the site-level infrastructure that delivers utilities from the street to each pad. This is often the biggest single 15-year category.
- Concrete pads. The pads themselves, plus any HVAC, trash, or utility-specific concrete work.
- Site drainage. Storm drains, catch basins, culverts, drainage swales, retention basins.
- Fencing. Perimeter fencing and any interior fencing.
- Landscaping. Trees, turf, irrigation systems, landscape lighting, planters.
- Exterior site lighting. Street lighting, walkway lighting, parking lot lighting.
- Common area improvements. Playgrounds, picnic areas, mail kiosks, signage.
- Retaining walls. Often substantial on sloped properties.
5-year property
- Appliances and equipment in common buildings (clubhouse kitchens, laundry equipment, office equipment)
- Carpet and removable flooring in common areas
- Pool and spa equipment (pool shell itself is typically 15-year)
- Decorative fixtures in clubhouses and common buildings
27.5-year property (the smaller bucket)
- Clubhouse, laundry building, office, maintenance building structure
- Building-level plumbing, electrical, HVAC, roofing on those structures
On a typical MHP, 40%–60% of the total depreciable basis ends up in the 15-year bucket and another 2%–5% in the 5-year bucket. That's dramatically higher than any single-family or small multifamily rental.
What the math looks like on a real park
Here's a worked example. A 50-pad mobile home park acquired in 2026:
- Purchase price: $2,500,000
- Land value: $625,000 (25%)
- Depreciable basis: $1,875,000
- Acquired after January 19, 2025 (100% bonus eligible)
Without a cost segregation study:
Full $1,875,000 depreciated straight-line over 27.5 years = $68,182/year for 27.5 years.
With a cost segregation study (typical MHP reclassification):
- 50% to 15-year land improvements: $937,500
- 3% to 5-year property: $56,250
- Remaining 27.5-year property: $881,250
With 100% bonus depreciation on short-life components in Year 1:
- 5-year property: $56,250 (Year 1, 100% bonus)
- 15-year land improvements: $937,500 (Year 1, 100% bonus)
- 27.5-year property: ~$32,045 (Year 1, straight-line)
- Total Year 1 depreciation: ~$1,025,795
That's roughly 15x the baseline straight-line number. At a 32% marginal tax rate, the additional Year 1 tax savings is ~$306,000 — on a single study. This is why mobile home parks are arguably the most impactful cost segregation opportunity in residential real estate.
Look-back studies work especially well on MHPs
If you own a mobile home park that you've been depreciating straight-line for years, a look-back study can generate a catch-up deduction that's genuinely life-changing. Your CPA uses the report to file IRS Form 3115 and claim all missed depreciation. Because 40%–60% of a park's basis is 15-year property, and much of that would have qualified for bonus depreciation in the years it was placed in service, the prior-year depreciation you missed often runs into the mid- to high-six figures — or even seven figures on a larger park.

Documentation matters more on MHPs, not less
Because MHP studies produce such large reclassification percentages, the documentation backing those classifications is where the report earns its keep. A quality MHP cost segregation study should include:
- Site plans or surveys, where available, documenting the extent of roads, utility runs, and site features
- Photo coverage of every major site improvement — roads, utility vaults and pedestals, pads, landscaping, fencing, signage, and common buildings
- Aerial or satellite imagery documenting the overall layout and scale of the park
- Methodology notes explaining how basis was allocated across the many land improvement categories
- Public records (county assessor, GIS data) corroborating the property dimensions and improvements
Thin documentation on an MHP study is a problem precisely because the dollar stakes are so high. A $1M reclassification with no supporting photos is an enormous audit exposure. A $1M reclassification with comprehensive site documentation is a well-built report that defends itself.
When MHP cost segregation makes sense
- You own the park (not just the homes). Cost segregation value comes from the land improvements — the roads, utilities, and site infrastructure — not from the mobile homes themselves. Park owners see the full opportunity.
- You have taxable income to offset. Given the size of a typical MHP catch-up deduction, this is almost always "yes."
- You plan to hold for at least several years. Recapture at sale reduces net benefit on short holds. Park owners typically hold for decades, which makes the math very clean.
- You're buying a park in 2026 and want to capture the full 100% bonus. Do the study the year you place it in service.
- You've owned a park for years without a study. A look-back study gives your CPA everything needed to file Form 3115 — usually a major opportunity.
Bottom line
Mobile home parks are arguably the single strongest residential cost segregation opportunity, because land improvements — roads, utility infrastructure, pads, and site features — dominate the cost basis. A properly done study can reclassify 40%–60% of the depreciable basis into 15-year property, and with 100% bonus depreciation, that means Year 1 deductions that often run into the hundreds of thousands or millions of dollars.
