A park-owned home is the only asset in a manufactured housing community that has to be right in four places at once: the fixed asset register, the rent roll, the tax return and the title file. Most operators get two of the four.

The reason is not carelessness. It is that a rented manufactured home does not behave like anything else on the balance sheet. Federal tax calls it a building. Your state DMV calls it a vehicle. It costs $35,000, depreciates over 27.5 years, and can be towed away in an afternoon. Its rehab spend splits between repair and capital on rules written for office towers. And when you finally sell it to the resident living in it, where the gain lands depends on a decision you made when you bought it.

This guide covers what actually goes into the home's basis, how the depreciation schedule is built, which rehab dollars capitalise and which do not, the disposal mechanics for all three exit routes, and the journal entries behind each.

This is general information, not tax advice. Several positions below are genuinely unsettled, and we say so where they are. Confirm treatment with your own adviser before you rely on any of it.

Key takeaways

• A rented manufactured home is 27.5-year residential rental property, depreciated straight line on the mid-month convention — not the half-year convention most operators assume.
• The clock starts when the home is ready and available to rent, not when a resident moves in. A home sitting finished and vacant is already depreciating.
• Bonus depreciation does not reach the home. It stops at 20 years. Your pads, roads and utility runs qualify at 15 years; the home does not.
• The $2,500 de minimis safe harbor expenses most small rehab items outright, but the procedure has to exist at the start of the tax year.
• The small taxpayer safe harbor is capped at the lesser of $10,000 or 2% of unadjusted basis — on a $35,000 home that is $700, which is the prong that will actually bind.
• On sale, §1250 ordinary recapture is normally zero, but the depreciation comes back as unrecaptured §1250 gain at up to 25%.
• Time-sensitive: an operator who elected out of §163(j) in 2022–2024 has until 15 October 2026 to withdraw that election and recover bonus depreciation on land improvements.

Before anything: decide what the home is

The classification comes first, because everything downstream follows from it and it cannot be fixed retroactively.

Only the first is the subject of this article. The wider framing — why an MH community runs two registers, and how the three classifications interact — is in our guide to manufactured housing community accounting.

One practical warning before you go further. If you run a rental fleet and a retail sales operation out of the same entity, the line between "fixed asset" and "inventory" is a facts-and-circumstances test applied at the moment of sale, not a box you tick at purchase. Operators who do both should separate them by entity, or at minimum document intent at acquisition, home by home.

What goes into basis

Basis is the acquisition cost plus everything required to get the home in place and ready to rent. In practice:

Capitalise into the home:

• Purchase price of the home, including sales tax and any dealer or freight charges
• Transport and set: hauling, blocking, levelling, tie-downs, skirting
• Utility connections made to the home itself
• Steps, landings and any attached structures
• Rehab performed before the home is placed in service — all of it, without applying the repair-versus-improvement test, because pre-service costs are acquisition costs
• Legal, titling and inspection fees attributable to the home

Do not capitalise into the home:

• The pad, the utility runs to the pad, the road and the landscaping. These are 15-year land improvements, a different asset class with a different life, a different method and — critically — bonus eligibility the home does not have.
• Appliances, carpet and furniture, which are 5-year property.
• Land, which is never depreciable.

That three-way split is not bookkeeping pedantry. It is the difference between deducting a large share of your spend immediately and deducting it over 27.5 years.

Building the depreciation schedule

Three parameters, and two of them are commonly wrong.

The 27.5-year life is explicit in the code and the publications. IRS Publication 527 defines the class as "any real property that is a rental building or structure (including a mobile home) for which 80% or more of the gross rental income for the tax year is from dwelling units" (IRS Publication 527).

The mid-month convention is the one operators miss. IRC §168(d)(2) applies the mid-month convention to residential rental property specifically; §168(d)(1) applies the half-year convention to everything else by default Cornell LII. So a home placed in service on 3 March gets half a month of March, not half a year. Your 15-year site improvements, sitting in the same project, use half-year. Two conventions, one invoice batch.

There is a useful wrinkle in the mid-quarter test. Publication 527 states the trigger applies where late-year placements exceed 40% of the basis of all depreciable property placed in service that year "(except real property)" — and the homes are real property. They sit outside the test on both sides of the fraction, which means a large Q4 home purchase does not drag your appliances into mid-quarter treatment.

The 15-year classification for site improvements comes from Rev. Proc. 87-56 asset class 00.3, quoted in Rev. Rul. 2001-60 as covering "improvements directly to or added to land" including "sidewalks, roads… drainage facilities, sewers… fences, landscaping, shrubbery" (IRS Rev. Rul. 2001-60). Note the method: 150% declining balance under §168(b)(2), not the 200% that applies to 5-year property.

When the clock actually starts

Publication 527 is unambiguous: "You place property in service in a rental activity when it is ready and available for a specific use in that activity." Its own worked example has a property placed in service on the date it was listed for rent, two months before a tenant moved in.

For an MH operator this is money-: A home that is set, connected, habitable and listed is placed in service — even if it sits empty through the winter. Operators who start the schedule at move-in are giving away months of depreciation, every home, every year. Document the ready-and-available date in the home record: the completed set, the certificate of occupancy or equivalent, the listing.

The bonus depreciation split

The One Big Beautiful Bill Act restored 100% bonus depreciation for qualified property acquired and placed in service after 19 January 2025. Property placed in service between 1 January and 19 January 2025 remains at 40%.

But qualified property is limited to assets with a recovery period of 20 years or less. So:

Read that table next to the one above and the planning point writes itself: on a park acquisition or an infill programme, the allocation between the home and the site improvements is worth real money in year one. Site work is fully expensed. The home is not.

Section 179 is available too, and reaches further than most operators think. The limit is $2.5 million for tax years beginning in 2025, rising to $2,560,000 for 2026 with the phase-out beginning at $4,090,000. More importantly, the Tax Cuts and Jobs Act removed the lodging exclusion from §179 for property placed in service in tax years beginning after 2017 — so appliances, furniture and equipment inside rental homes are §179-eligible. The home itself is not, because §179 requires §1245 property.

Which brings us to the question underneath all of this.

Is the home §1245 or §1250 property? The honest answer

This determines bonus eligibility, §179 eligibility and how gain is taxed on sale. It is also not settled, and anyone who tells you otherwise is selling something.

The case for §1250 (real property), which is what Publication 527 implies:

§1250(c) defines section 1250 property as "any real property (other than section 1245 property)" subject to depreciation. §1245 property includes "personal property," which Reg. §1.48-1(c) defines as "any tangible property except land and improvements thereto, such as buildings or other inherently permanent structures" — and Reg. §1.48-1(e)(1) defines a building as "any structure or edifice enclosing a space within its walls, and usually covered by a roof." A sited home enclosing dwelling space is a building; a building is not personal property; therefore it is §1250 property. The IRS calls it "real property" in Publication 527 and puts it in the 27.5-year class.

The case for §1245 (personal property), which cost segregation vendors routinely take:

A manufactured home on blocks and tie-downs, titled as a vehicle, movable in a day, is arguably not an inherently permanent structure. Cost segregation studies on MH communities frequently allocate a large share of basis — one published study used 47% — to 5-year property described as "park-owned movable homes, utility hookups, signage, furnishings." The IRS's own Cost Segregation Audit Techniques Guide concedes there is "no general bright-line test" for separating §1245 from §1250 property and that each situation is "factually intensive" (IRS ATG, Chapter 2).

What we could not find: any revenue ruling, regulation or Tax Court decision that squarely decides whether a park-owned rental manufactured home is §1245 or §1250 property. We looked. There is no on-point authority in the public record.

What that means practically. The §1250 position is the conservative one and follows directly from Publication 527. The §1245 position is defensible for homes that are genuinely mobile, vehicle-titled and not on a permanent foundation — but it is a position, not a conclusion, and it changes everything downstream: bonus depreciation becomes available, §179 becomes available, and all the depreciation comes back as ordinary income on sale rather than at the 25% unrecaptured-§1250 rate. Take the cost segregation study. Take advice with it, and make sure whoever signs the return owns the position.

Rehab: which dollars capitalise

Once a home is in service, every dollar you spend on it faces the same test. The rules come from the tangible property regulations, and there are three safe harbors that between them handle most of your spend.

The improvement standard — betterment, adaptation, restoration

Reg. §1.263(a)-3(d) requires capitalisation where amounts "(1) Are for a betterment… (2) Restore the unit of property… (3) Adapt the unit of property to a new or different use" (eCFR §1.263(a)-3).

The IRS's plain-language version is more useful at the invoice desk:

• Betterment — fixing a material condition or defect that existed before acquisition, a material addition, or a material increase in capacity.
• Restoration — replacing a major component or substantial structural part, or restoring property that has deteriorated to a state of disrepair.
• Adaptation — adapting the property to a new or different use inconsistent with its use when placed in service.

A failed water heater replaced like for like is a repair. A re-roof is a restoration. A full gut renovation on a repossessed home is a betterment, and often a pre-service acquisition cost anyway.

Safe harbor 1 — de minimis, $2,500 per item

Reg. §1.263(a)-1(f) permits expensing under a dollar threshold. Notice 2015-82 raised the limit for taxpayers without an applicable financial statement from $500 to $2,500 (IRS Notice 2015-82). With an AFS it is $5,000. The threshold is not inflation-indexed and has not moved since.

Two conditions catch people out. The procedure must be in place at the beginning of the tax year, not written in March when the accountant asks. And if you have an AFS the procedure must be in writing — the IRS states plainly that "If you have AFS, you must have the accounting procedures in writing." Without an AFS, writing is not legally required but the procedure still has to exist and be applied consistently. Write it down anyway; it costs nothing.

Safe harbor 2 — routine maintenance

Reg. §1.263(a)-3(i) covers activities you reasonably expect, when the property is placed in service, to perform more than once during a 10-year period for building structures and systems. Gutter cleaning, HVAC servicing, periodic exterior work.

Safe harbor 3 — small taxpayer, and the 2% trap

Reg. §1.263(a)-3(h) lets a taxpayer with average annual gross receipts of $10 million or less expense repairs and improvements on a building with unadjusted basis of $1 million or less, up to the lesser of $10,000 or 2% of that building's unadjusted basis.

Read the 2% prong against a $35,000 home: the cap is $700. Not $10,000. The safe harbor is applied per building, per year, and on manufactured homes the percentage will bind almost every time. Worse, the amounts you expensed under the de minimis and routine-maintenance safe harbors for that same building count against the cap.

This is the single most misunderstood provision in MH accounting. Operators hear "$10,000 safe harbor" and budget accordingly, then discover at year end that their $4,000 rehab on a $35,000 home blew through a $700 ceiling and the whole amount has to be tested on the merits.

Unit of property, and the ghost roof

Reg. §1.263(a)-3(e)(2)(i) states that "each building and its structural components… is a single unit of property," with nine building systems — HVAC, plumbing, electrical, fire protection, security, gas distribution and others — analysed separately. There is no IRS pronouncement naming manufactured homes, so this follows by application rather than by citation: if you depreciate a home as 27.5-year residential rental property, you are treating it as a building, and its systems are carved out for the improvement test.

That is why a furnace replacement so often capitalises. The "major component" restoration test runs against the HVAC system, not against the whole home — and a furnace is most of the HVAC system.

It also creates the ghost-roof problem: replace a roof, capitalise the new one, and you are now depreciating two roofs. The fix is the partial disposition election at Reg. §1.168(i)-8(d)(2)(i): "A taxpayer may make an election under this paragraph (d)(2) to apply this section to a disposition of a portion of an asset" (eCFR §1.168(i)-8). Elect it, write off the old roof's remaining basis as a loss, and the register stops carrying an asset that is in a skip. The election is made on a timely filed original return, per disposition, per year.

Disposal: three exits, three treatments

Exit 1 — sold to the resident

The asset leaves the register. Remove cost and accumulated depreciation, recognise gain or loss on the difference between proceeds and net book value.

The tax result is where it gets interesting, and it is better than most operators expect. Because §168(b)(3)(B) mandates straight-line depreciation for residential rental property, there is no "additional depreciation" under §1250(b)(1) — so §1250 ordinary recapture is normally zero. The Instructions for Form 4797 confirm that section 1250 recapture does not apply to MACRS residential rental property placed in service after 1986 and depreciated straight line (IRS Form 4797 instructions).

Instead the depreciation resurfaces as unrecaptured section 1250 gain, taxed at a maximum of 25%: "The portion of any unrecaptured section 1250 gain from selling section 1250 real property is taxed at a maximum 25% rate" (IRS Topic No. 409).

Compare that to the §1245 alternative, where every dollar of depreciation returns as ordinary income at full marginal rates. The classification question from earlier has a number attached to it, and this is where the number shows up.

Exit 2 — sold with seller financing

Same disposal accounting, but the consideration is a note rather than cash, and there is a trap. If you regularly seller-finance homes, the installment method is closed to you — IRC §453(l)(1)(A) treats a disposition of personal property by someone who regularly sells that type of property on the installment plan as a dealer disposition, excluded from installment treatment. Full gain in the year of sale, cash over ten years.

The structuring, licensing and Regulation Z consequences are covered in chattel loans for community operators and rent-to-own in manufactured housing.

Exit 3 — scrapped or abandoned

Reg. §1.168(i)-8 requires that on abandonment, loss be recognised "in the amount of the adjusted depreciable basis of the asset at the time of the abandonment," conditioned on the taxpayer intending "to discard the asset irrevocably."

IRS Publication 544 defines the act: "You abandon property when you voluntarily and permanently give up possession and use of the property with the intention of ending your ownership but without passing it on to anyone else."

Six conditions to satisfy, and vacancy alone satisfies none of them: an affirmative act of abandonment; intent to discard irrevocably; permanence; the asset must not sit in a general asset account; no sale, exchange or transfer to anyone; and if the home secures debt, expect the transaction to be recast with debt-discharge consequences.

The upside: because it is not a sale or exchange, §1231 does not apply and the loss is fully ordinary — often better than a §1231 loss. Homes recovered through a state abandonment process are a different matter entirely, covered in abandoned homes in manufactured housing communities.

The journal entries

Illustrative, for a home bought at $28,000, rehabbed and placed in service at a $34,500 basis, sold three years later to the resident for $37,000 with $3,760 of accumulated depreciation.

Two notes. Entry 3 matters more than it looks — the placed-in-service date, not the purchase date, starts the schedule and fixes the mid-month convention. And entry 6 should be paired with a partial disposition election on the old furnace if the remaining basis is material.

The account structure behind these entries is covered in the manufactured housing chart of accounts; the general capitalisation policy question is in our guide to separating CapEx from OpEx.

Two things that will cost you money this year

1. Converting a rental home to inventory destroys the tax treatment: IRC §1231(b)(1) excludes property held "primarily for sale to customers in the ordinary course" from §1231 treatment, and §1221(a)(1) does the same for capital asset treatment. Gain on a home genuinely converted to dealer inventory is ordinary in full, and the 25% unrecaptured-§1250 cap is gone. Depreciation also stops — Reg. §1.167(a)-2 states the allowance "does not apply to inventories or stock in trade."

We could not find IRS guidance addressing conversion from depreciable rental property to inventory directly. The test is applied at the moment of sale on the facts, so one opportunistic sale out of a rental fleet does not automatically make you a dealer. A programme does.

2. The §163(j) withdrawal deadline is 15 October 2026: Many leveraged operators made the §163(j)(7)(B) electing-real-property-trade-or-business election in 2022–2024 to escape the interest limitation, paying for it with ADS depreciation — 30-year homes, 20-year land improvements, and no bonus depreciation at all. OBBBA restored the EBITDA-based ATI computation, which makes that election unattractive for many.

Rev. Proc. 2026-17 allows withdrawal: a taxpayer in scope "may withdraw its § 163(j)(7) election for a 2022, 2023, or 2024 taxable year by filing… an amended Federal income tax return," due "on or before the earlier of (i) October 15, 2026, or (ii) the end of the applicable period of limitations on assessment" (Rev. Proc. 2026-17). Withdrawing restores non-ADS depreciation and bonus eligibility on land improvements.

If that describes your structure, this is a conversation to have with your adviser in the next few weeks, not next spring.

How RIOO handles park-owned home accounting

RIOO is a property management platform built natively on Oracle NetSuite, and this article is the clearest illustration of why that matters. Everything above is general ledger work. A rent-roll tool cannot do any of it.

In a conventional platform a park-owned home is forced into a unit lease record, which severs the physical asset from the ledger — the home earns rent in one system and depreciates in another, and nothing reconciles. NetSuite closes that gap because both halves post to the same books.

• Each home is a fixed asset record with cost, in-service date, method, convention, depreciation schedule, book value and disposal — alongside its serial and HUD label numbers, manufacturer, wind zone and condition.
• Different asset classes run different schedules automatically, so the 27.5-year mid-month home and the 15-year half-year pad it sits on depreciate correctly without anyone remembering the difference.
• Rehab spend is classified when the invoice is coded, against the home it belongs to, so the repair-versus-capital decision is made once by the person who knows — not reconstructed at year end from a bank statement.
• Disposal is one transaction that removes cost and accumulated depreciation, books the gain or loss, and — where the home is seller-financed — opens the note receivable on the same customer record as the resident's lot rent.

The test: can you produce, for any home, its basis, its accumulated depreciation, its remaining life and its capitalisation history, in one place? If you carry park-owned home exposure and want to see what that looks like in one system, book a demo.

Conclusion: the register is the strategy

Park-owned homes are usually discussed as an operating question — how many should you own, and should you convert them. That debate is covered in our guide to park-owned vs tenant-owned homes.

But you cannot answer it without the accounting. "Should we sell this home?" is a question about net book value, remaining life, accumulated depreciation, the fully-loaded cost of the last three years, and what the gain will be taxed at. An operator whose homes live in a spreadsheet cannot answer any of that per home, which is why the decision usually gets made on instinct and revisited during due diligence.

Four things to be able to produce for any home, on any day:

1. Basis, accumulated depreciation and net book value — with the placed-in-service date behind them.
2. Every dollar spent since, split between repair and capital, with the reason.
3. What it earned, net of what it cost to keep.
4. What the tax result would be on each of the three exits.

Get those four right and the conversion decision from the POH-versus-TOH question becomes arithmetic. Get them wrong and you are running a rental-home programme you cannot value.

Frequently asked questions

Q1. How do you depreciate a park-owned mobile home?
Over 27.5 years, straight line, using the mid-month convention. IRS Publication 527 places a rental building or structure "including a mobile home" in the residential rental class where at least 80% of gross rental income comes from dwelling units. The pad, roads and utility runs under the home are separate 15-year land improvements.

Q2. When is a rental manufactured home placed in service?
When it is ready and available to rent, not when a resident moves in. IRS Publication 527 states property is placed in service "when it is ready and available for a specific use in that activity," and its own example uses the date a property was listed for rent rather than the date it was let.

Q3. Can you take bonus depreciation on a park-owned home?
Generally no. Bonus depreciation requires a recovery period of 20 years or less, and a rental manufactured home is 27.5-year property. Site improvements such as pads, roads and utility runs are 15-year property and do qualify at 100% for property placed in service after 19 January 2025. Cost segregation studies sometimes take a more aggressive position on the homes themselves.

Q4. Is a park-owned home section 1245 or section 1250 property?
There is no direct IRS ruling. The conservative position is §1250, following Publication 527's treatment of a rental mobile home as real property in the 27.5-year class. Cost segregation vendors frequently argue §1245 for homes that are vehicle-titled and not permanently affixed. The choice changes bonus eligibility, §179 eligibility and whether gain is taxed as ordinary income or at the 25% unrecaptured §1250 rate.

Q5. What repairs on a park-owned home can be expensed?
Items under $2,500 per invoice or item qualify under the de minimis safe harbor, provided the accounting procedure existed at the start of the tax year. Routine maintenance you expect to perform more than once in ten years also qualifies. Everything else is tested against the betterment, adaptation and restoration standard.

Q6. Does the $10,000 small taxpayer safe harbor apply to manufactured homes?
It applies, but the cap is the lesser of $10,000 or 2% of the building's unadjusted basis. On a $35,000 home that is $700, so the percentage limit binds long before the dollar limit. Amounts expensed under the de minimis and routine maintenance safe harbors for that home count against the same cap.

Q7. What happens to depreciation when you sell a park-owned home to the resident?
Because residential rental property must be depreciated straight line, there is normally no §1250 ordinary recapture. The depreciation instead becomes unrecaptured section 1250 gain, taxed at a maximum rate of 25%. Remove cost and accumulated depreciation from the register and recognise gain or loss on the difference between proceeds and net book value.

Q8. Can you write off an abandoned manufactured home?
Yes, at its adjusted depreciable basis, provided you affirmatively abandon it with the intention of discarding it irrevocably and permanently, do not transfer it to anyone, and have not placed it in a general asset account. Because it is not a sale or exchange the loss is fully ordinary. Vacancy or disuse alone is not abandonment.

Q9. Should park-owned homes be tracked as inventory or fixed assets?
It depends on intent. Homes held to rent are depreciable fixed assets. Homes held primarily for sale to customers in the ordinary course of business are inventory, are not depreciable, and produce ordinary income on sale. Converting a rental home to inventory loses §1231 treatment and the 25% unrecaptured §1250 rate, so the direction of travel matters.
