MHP Operating Expenses: What’s Deductible Line by Line

By Harry Shurek, EA | The MHP Accountant®

One of the consistent patterns in MHP tax returns reviewed by this firm is inconsistency — some owners are deducting everything aggressively without documentation to support it, others are overcapitalizing routine maintenance and unnecessarily deferring deductions. Both approaches cost money. The first creates audit exposure. The second costs real cash in the present.

This guide covers every major operating expense category for a mobile home park, line by line: whether it’s deductible, how to categorize it, what documentation the IRS expects, and where owners most commonly make mistakes. You will not find vague generalities here — every item is addressed with MHP-specific context.

This post covers operating expenses only. Depreciation is a separate category covered in How to Calculate Depreciation on a Mobile Home Park. Capital improvements are addressed in the context of each relevant line item below.

Management Fees

Deductible: Yes, as an ordinary and necessary business expense.

If you use a third-party property management company, their fees are fully deductible in the year paid. Management fees are typically calculated as a percentage of gross collected income — your management agreement should specify this percentage and base.

If you self-manage the park and pay yourself a management fee through an entity structure, that fee must be reasonable in amount and properly documented with a written management agreement, actual services performed, and consistency with what you would pay an arm’s-length third party for the same services. Inflated self-management fees paid to related parties are a known audit concern.

Documentation: retain the management agreement, invoices or monthly statements, and payment records. For related-party arrangements, also retain documentation of the services performed.

Insurance

Deductible: Yes.

Premiums paid for commercial property insurance, liability insurance, umbrella coverage, and loss of rents insurance are all deductible in the year the premium is paid (for cash-basis taxpayers). If you pay an annual premium that covers periods beyond the current tax year, you may need to prorate the deduction under the 12-month rule.

Documentation: insurance declarations pages, premium invoices, and proof of payment. Maintain these even for older years since insurance premium deductions can be reviewed in connection with an insurance claim.

Property Taxes

Deductible: Yes.

Real property taxes assessed on the park land and improvements are deductible. For cash-basis taxpayers, the deduction is taken in the year payment is made to the taxing authority, not when the liability accrues.

If your park spans multiple parcels in multiple tax districts (not uncommon for large parks), track each tax bill separately and confirm they are all captured in your expense records. Taxes paid in escrow through your mortgage servicer should reconcile to your year-end escrow statement — use the escrow statement to verify the amounts actually paid to the taxing authority, not just amounts deposited into escrow.

Utilities

Deductible: Yes.

Utility expenses for services paid by the park — master-metered water/sewer, common area electricity, trash collection, and natural gas for common areas — are deductible operating expenses. This is one of the more variable expense categories across MHPs because the billing structure varies widely: some parks bill tenants directly, others master-meter and pass through, others absorb utility costs as part of lot rent.

The only portion deductible is what the park actually pays after any tenant reimbursements. If tenants pay their own utilities directly, there is no utility expense to deduct. If you bill tenants a flat fee for utilities included in lot rent, the entire utility cost is deductible against the income that includes the utility allocation.

Maintenance and Repairs Versus Capital Expenditures

Deductible: Yes for repairs; capitalized and depreciated for improvements.

This is the most complex categorization decision in MHP operating expenses and the most litigated area under the IRS tangible property regulations. Here are the practical rules:

A deductible repair maintains the property in its current condition, does not materially add to its value, and does not substantially extend its useful life. Fixing a broken lot pedestal, patching a pothole, repairing a fence section, unclogging a sewer line — these are routine repairs deductible when paid.

A capital improvement betters the property, restores a major component to its original condition, or adapts it to a different use. Resurfacing the entire park road network, replacing the entire sewer system, rebuilding a retaining wall that has failed — these are capital improvements to be depreciated over the appropriate MACRS class life.

The IRS regulations use the concept of a “unit of property” (UOP) to determine whether an expenditure is a repair to a component or a restoration of a major system. An entire park road network is a larger UOP than a single pothole. Replacing 80% of the road surface in a single year is more likely to be a capital improvement than a repair, even if each section is treated as a separate repair project.

Documentation: for borderline repair vs. capital determinations, maintain vendor invoices, scope-of-work descriptions, photographs of the condition before and after, and a written rationale for your categorization. You cannot reconstruct this record retroactively.

Landscaping and Grounds Maintenance

Deductible: Yes for routine maintenance; capitalized for new improvements.

Regular mowing, leaf removal, seasonal plantings, and routine grounds upkeep are deductible operating expenses. Creating a new landscaping feature — installing an irrigation system, adding ornamental plantings to a previously unimproved entrance, constructing a new common-area garden — is a capital improvement classified as a 15-year land improvement and depreciated accordingly.

Snow Removal

Deductible: Yes.

Payments to contractors for snow plowing, ice treatment, and seasonal clearing are deductible operating expenses. Keep invoices and service agreements. If you use park-owned equipment for snow removal, the equipment itself is a depreciable asset (not an operating expense), but fuel, maintenance, and operator labor for snow removal with that equipment are operating expenses.

Advertising and Marketing

Deductible: Yes.

Online listing fees (Apartments.com, MHVillage, etc.), print advertising, website costs, and promotional materials for tenant recruitment are deductible. Website development costs present a nuance: routine website maintenance and hosting are operating expenses, while creating a new website or major redesign involves capitalization rules under Treas. Reg. §1.263(a).

Professional Fees

Deductible: Yes.

Fees paid to CPAs, enrolled agents, attorneys, and other professionals for services related to the operation of the park are deductible. This includes tax preparation, bookkeeping, lease review, eviction proceedings, and general counsel on park operations.

Fees paid for capital transactions — acquisition due diligence legal costs, title insurance, attorney fees for a 1031 exchange — are generally not currently deductible operating expenses. They are added to the basis of the acquired property or treated as transaction costs. The distinction between operating professional fees (deductible) and transaction professional fees (capitalized) requires careful categorization on your books.

Office Expenses

Deductible: Yes.

Supplies, postage, printing, software subscriptions (property management software, accounting software, communication tools), and other routine office costs for operating the park are deductible. If you maintain a dedicated home office used exclusively and regularly for park management, you may be able to deduct a portion of home expenses under IRC §280A — document the square footage and exclusivity of use.

Vehicle and Travel Expenses

Deductible: Yes, with documentation.

This is one of the most audited categories on MHP returns. The IRS requires contemporaneous records for vehicle deductions — a mileage log that includes date, starting point, destination, business purpose, and miles driven. A year-end estimate is not sufficient and will not survive audit.

You have two options for vehicle deductions: actual expense method (deduct actual fuel, maintenance, insurance, registration, and depreciation prorated for business use percentage) or the standard mileage rate (multiply business miles by the IRS-published rate, which changes annually). You cannot switch freely between methods once you have claimed depreciation on a vehicle.

Travel to the park for management visits is deductible. Travel to seminars, trade shows (MHI conference, state MHA meetings), and educational events related to your MHP business is deductible. Personal travel combined with business travel requires allocation. Travel from home to the park and back is generally deductible as it is travel to a business location — but document the business purpose for each trip.

Employee Wages and Payroll

Deductible: Yes.

If you employ on-site managers, maintenance workers, or office staff, their wages, employer payroll taxes (Social Security, Medicare, federal and state unemployment), and employee benefits are deductible. Payroll taxes are reported and paid through your payroll system and deducted on Schedule E or Form 1065 (partnership) as appropriate.

Owner-operators who structure their park in an S-corporation and pay themselves a salary should ensure the salary is reasonable — the IRS scrutinizes low salaries in S-corps where the owner is the primary worker, as this is a mechanism some taxpayers use to reduce self-employment tax exposure. The salary must reflect market compensation for the services rendered.

Bank Charges and Financing Costs

Deductible: Bank charges yes; loan interest yes; loan origination fees — amortized over the loan term.

Monthly bank service charges, wire transfer fees, ACH processing fees, and credit card processing fees are deductible operating expenses. Mortgage interest is deductible. Loan origination fees (points) paid on a business property loan are generally capitalized and amortized over the life of the loan, not deducted in full in the year paid.

HOA and Association Dues

Deductible: Yes for business-related association memberships.

Dues paid to the Manufactured Housing Institute (MHI), your state manufactured housing association, local business associations, or other industry groups related to MHP operation are deductible as business expenses. Country club memberships and social organization memberships are generally not deductible, even if you discuss business there.
