Cost Segregation on Park-Owned Homes: What Qualifies and How It Works

Park-owned homes present one of the more nuanced intersections in MHP taxation. When you own homes that you rent to residents — rather than just charging lot rent to tenant-owned home (TOH) residents — the tax treatment of those homes matters significantly for your depreciation strategy.

Here is the part that surprises most MHP owners: in a cost segregation study, park-owned homes (POH) are typically not the primary reclassification target. POHs are generally already classified as 5-year personal property under MACRS — the shortest residential classification in the code. They don’t need to be moved to a shorter life because they’re already there.

But that does not mean POHs are irrelevant to your cost segregation study. They need to be correctly documented, correctly separated from other asset categories, and correctly handled for bonus depreciation purposes. When they’re not, the consequences range from missed deductions to IRS reclassifications that work against you.

Why POHs Are Already at the Short End of the MACRS Spectrum

Manufactured homes — also called mobile homes — are classified as tangible personal property under the tax code when they remain personal property under state law. This is a critical distinction. If a manufactured home is titled as personal property (not converted to real property under the relevant state’s titling process), it is treated as 5-year MACRS property for depreciation purposes.

Five-year MACRS means the home is depreciated over a five-year recovery period using the double-declining-balance method with a switch to straight-line when that becomes more favorable. This is dramatically faster than the 27.5 years that would apply to residential real property or the 39 years for commercial property.

The key word is “titled.” The manufactured home must be titled as personal property — not converted to real property — to maintain 5-year classification. If you or a prior owner went through a real property conversion process (sometimes called “titling surrender” or “certificate of destruction” in various states), the home may have been reclassified as real property, which changes the depreciation treatment entirely.

The Real Risk: Accidental Bundling with Longer-Life Property

The primary cost segregation concern around POHs is not that they need to be reclassified shorter — it’s that they might accidentally be bundled with longer-life assets in a poorly designed study or an inadequately prepared depreciation schedule.

Here is how this happens in practice. When an MHP is purchased, the purchase price is allocated across various asset categories. If the engineer or accountant preparing the depreciation schedule is not MHP-savvy, they may lump the POHs into the overall real property basis — essentially treating them as part of the residential rental property and assigning them 27.5-year lives. This is incorrect and results in significantly slower depreciation on assets that should be coming off the books in five years.

A cost segregation study that covers a park with POHs must explicitly identify and document each home, confirm its titling status, assign it the correct 5-year MACRS life, and separate it clearly from the park infrastructure and structural components. This documentation work is part of what you are paying for in a qualified study.

Components Within a POH That May Be Separately Classified

A manufactured home is itself a single asset for most purposes, but there are components within or attached to POHs that may be separately classified and depreciated. The relevant analysis here follows the same framework as any personal property component identification:

Appliances: Refrigerators, ranges, dishwashers, and other appliances that are not permanently installed as structural components of the home may be separately classified. These are typically 5-year personal property, same as the home itself, but they have separate purchase prices and their own depreciation schedules — which matters when they are replaced.

HVAC units: Central air conditioning and heating systems installed in a manufactured home occupy a gray area. If they are truly a structural component of the home — built-in, not portable — they may be treated as part of the home’s basis rather than separately depreciable. Freestanding window units or portable equipment would be treated as separate personal property.

Skirting and steps: Vinyl or metal skirting and entry steps are generally personal property and may be separately identified in a study. Their useful lives and replacement patterns differ from the home structure itself.

Attached structures: Decks, porches, and storage sheds attached to POHs may be separately classified depending on their construction and permanence. Freestanding accessory structures on the lot may qualify as 15-year land improvements in some cases.

The value of separately identifying these components increases when you are replacing them. When you replace a component that was separately depreciated and still on the books, you can write off the remaining basis of the replaced component rather than simply adding the new cost. This gain-on-disposition analysis is something your MHP accountant should be tracking.

Bonus Depreciation Eligibility for POHs

This is where the 5-year classification becomes particularly valuable. Under current tax law, certain property with a MACRS recovery period of 20 years or less qualifies for bonus depreciation — an immediate expensing provision that allows you to deduct some or all of the asset’s cost in the year it is placed in service.

Five-year personal property — which includes correctly titled POHs — qualifies for bonus depreciation. This means that if you acquire a manufactured home as personal property and place it in service in a given tax year, it may be eligible for immediate expensing under bonus depreciation rules, subject to the applicable phase-down percentage and any elections you make.

The interaction between POH classification and bonus depreciation is one of the reasons that getting the titling and classification right from day one matters so much. A home that is incorrectly classified as 27.5-year residential rental property is not eligible for bonus depreciation. A correctly classified 5-year POH is. The difference in year-one deductions on a portfolio of POHs can be substantial.

The Purchase Price Allocation Question

When you acquire an MHP that includes POHs, the allocation of the purchase price among asset categories affects every depreciation calculation that follows. This allocation is documented on IRS Form 8594 (Asset Acquisition Statement) when the transaction is treated as an asset purchase, and it binds both the buyer and seller to consistent reporting.

If the Form 8594 allocation is done correctly — with proper amounts assigned to 5-year personal property (POHs), 15-year land improvements, 27.5-year structures, and non-depreciable land — the cost segregation study simply documents and confirms those allocations. If the allocation was done carelessly or without MHP expertise, the study may need to work with a different framework.

This is one of the reasons that involving an MHP-specialized tax advisor at closing — before the purchase price is allocated on Form 8594 — is significantly more valuable than bringing one in after the fact. The foundation of your depreciation strategy is laid at the moment of acquisition.

How Cost Segregation Studies Handle POHs Specifically

A qualified cost segregation engineer with MHP experience will approach POHs as follows:

First, they will inventory the POHs on the property — number, age, condition, and size. They will confirm or establish the cost basis allocated to each home from the acquisition documents or, for improvements after acquisition, from your records.

Second, they will verify or document the titling status of each home. This may involve reviewing state DMV records, title documents, or prior owner records. If a home was improperly converted to real property in the past, this is the point where that issue surfaces.

Third, they will assign the correct MACRS classification — 5-year for properly titled personal property — and document this in the study report with the supporting titling evidence.

Fourth, they will identify any separately depreciable components (appliances, HVAC, skirting) and assign those to their appropriate categories.

The result is a comprehensive asset schedule for each POH that supports both current depreciation and future component-level accounting when replacements are made.

Linking POH Classification to Your Overall MHP Tax Strategy

POH classification doesn’t exist in isolation. It fits into a broader picture that includes how your park is structured (entity type, management company setup), how you are handling lot rent income and POH rental income differently, and how your overall passive activity profile affects whether accelerated depreciation can be used currently.

If you are considering adding POHs to a primarily TOH park — or converting TOH residents to POH arrangements — the tax implications of that shift deserve careful advance planning. The change affects not just depreciation but how income is characterized, what expenses are deductible, and how the park is valued for future financing or sale. See our overview of cost segregation vs straight-line depreciation for the broader framework of how these decisions interact.

For parks where you are conducting a lookback cost segregation study on a property you have owned for years, the correct historical treatment of POHs — were they ever properly classified as 5-year property? — will determine whether there is a catch-up adjustment available through Form 3115. Our guide on cost segregation for new vs existing MHPs addresses the lookback procedure in detail.

And if you are evaluating a cost segregation study as part of your acquisition strategy, understanding the bonus depreciation interaction with POHs is a key piece of the year-one tax planning. Our post on cost segregation and bonus depreciation covers the mechanics of how these two provisions work together across all asset categories in an MHP.
