How Much Does a Mobile Home Park Cost Segregation Study Cost?

Every mobile home park operator who has discovered cost segregation asks the same question: how much does the study cost, and is it worth it? The answer is not a single number. It depends on several factors specific to your park — and understanding those factors helps you evaluate whether you are getting a fair price for quality work.

More importantly, understanding cost is inseparable from understanding benefit. A cost segregation study is not a commodity expense. It is an investment that should generate measurable tax savings. If the savings do not exceed the fee, the study was not worth doing. That calculus needs to be run before you sign an engagement letter.

What Cost Segregation Does for MHP Owners

Under standard MACRS (Modified Accelerated Cost Recovery System) accounting, commercial real property — including the land improvements and infrastructure at a mobile home park — is depreciated over 39 years for non-residential real property components. That is a slow, flat-line reduction in taxable income.

A cost segregation study reclassifies portions of your park’s improvements into shorter depreciation lives: 5-year personal property, 7-year property, and 15-year land improvements. Shorter lives mean faster depreciation. Combined with bonus depreciation under current federal law, this can produce very large first-year deductions on a newly acquired or newly constructed park.

That acceleration is the benefit. The cost is the engineering study required to support the reclassification. The IRS requires that cost segregation studies be prepared by qualified professionals using accepted engineering methodologies — not simply by accountants making estimates without a site-level asset analysis.

What Drives the Cost of a Cost Segregation Study for Mobile Home Parks

Cost segregation fees for mobile home parks are not one-size-fits-all. The major variables that affect pricing are:

Park size and complexity. A 30-lot park with basic infrastructure — gravel roads, basic utilities, no clubhouse — is simpler to analyze than a 150-lot community with a clubhouse, pool, laundry facilities, paved roads, underground utilities, and a mix of POH and TOH units. More assets to classify means more engineering work and a higher fee.

Number of park-owned homes (POH). POH units are personal property, not real property, and they have different depreciation treatment than the land and infrastructure. If your park has a significant POH count, the study must address each home’s components, which adds scope.

Site inspection versus desktop study. A full-service cost segregation study includes an on-site inspection by a qualified engineer or cost segregation specialist. A desktop study uses construction documents, photos, and purchase data without a site visit. Desktop studies cost less but may not capture every reclassifiable asset — particularly site-specific items that are not visible in standard documentation. The IRS has not prohibited desktop studies, but the IRS Cost Segregation Audit Techniques Guide indicates that studies without site inspections carry greater risk of challenge.

Whether this is an acquisition, construction, or look-back. A look-back study — reclassifying assets from a prior-year acquisition without having done cost segregation at the time — involves additional complexity because it requires matching current asset classifications to historical costs. Look-back studies often cost slightly more than studies done contemporaneously with an acquisition.

Geographic location and site accessibility. Providers price travel into their fees. A remote rural park may carry a higher site-inspection cost than an urban community near major transportation.

Typical Fee Ranges

While fees vary by provider and market, cost segregation studies for mobile home parks typically range from a few thousand dollars for small, simple parks to significantly more for larger communities with complex improvements. Fee structures fall into two categories:

Fixed fee. A flat dollar amount agreed to before the study begins. This is the most common and generally the most appropriate structure. You know the cost before you commit, and the provider has no financial incentive to inflate the reclassifiable amounts.

Contingency fee. A percentage of the tax savings generated by the study. This structure creates a misalignment of incentives: the provider benefits from aggressively reclassifying assets, which increases audit risk. The IRS has flagged contingency fee arrangements in cost segregation as a potential audit concern. The IRS Cost Segregation Audit Techniques Guide notes that the fee structure may affect the independence and objectivity of the study. Fixed-fee arrangements are preferable for this reason.

When Is the Study Fee Deductible?

The cost of a cost segregation study is generally deductible as a professional service fee in the year it is paid, under the same treatment as accounting and consulting fees. This partially offsets the cash cost of the study — the net cost to you is the fee multiplied by one minus your marginal tax rate.

If you are in a 30% effective federal tax bracket, a $5,000 study fee has a net after-tax cost of approximately $3,500, because $1,500 of the fee is recovered through the deduction. This further improves the ROI calculation.

How to Evaluate the ROI on a Cost Segregation Study

The return on investment calculation for a cost segregation study follows a straightforward framework:

Step one: determine the estimated additional depreciation the study will generate in year one. A reputable provider should give you a projection before you engage them.

Step two: multiply the additional first-year depreciation by your marginal tax rate (federal plus applicable state). This is your estimated first-year tax savings.

Step three: compare the first-year tax savings to the study fee. If the savings in year one alone exceed the fee, the study has a positive ROI before accounting for any benefit in subsequent years.

For most MHP operators, a properly scoped cost segregation study generates first-year savings that far exceed the study fee — often by a ratio of 10:1 or more on larger acquisitions. The ROI analysis is the right frame, not the absolute dollar cost of the study.

Red Flags in Cost Segregation Pricing

Not all cost segregation studies are equal. Here are the warning signs that a study may not deliver what it promises:

Unusually low fees with no site inspection. A very low-cost desktop study completed without visiting your park may miss substantial reclassifiable assets — particularly site improvements that are not reflected in standard purchase documentation. You may pay less for the study but leave significant depreciation on the table.

No engineering personnel involved. The IRS and tax courts have consistently upheld cost segregation studies that are based on engineering analysis. Studies prepared solely by accountants without engineering support are more vulnerable to challenge. Ask whether a licensed engineer or cost segregation specialist with engineering training is performing the analysis.

Vague or generic reports. A quality cost segregation study produces a detailed asset-by-asset report, not a summary percentage allocation. The report should identify specific assets, assign them to specific MACRS asset classes, and explain the methodology used for each classification. A generic report that simply says “15% is 5-year property” without supporting analysis is not a defensible study.

No discussion of your specific park. A provider who quotes a fee without asking about your park’s size, improvement types, POH count, or acquisition price is not scoping the work seriously. A properly priced study requires enough information to estimate the scope before a fee is set.

Coordinating the Study with Your MHP Return

The most important timing consideration for cost segregation is this: the study should be completed before your first tax return is filed for the acquisition year. If you file without a cost segregation study and later want to reclassify assets, you can — using IRS Form 3115, Change in Accounting Method — but this adds complexity and professional fees to the correction process.

Done right, cost segregation integrates directly with your depreciation schedule from day one. The study generates an asset listing that feeds directly into the fixed asset schedule on your MHP return. Your accountant should coordinate directly with the cost segregation firm to ensure the asset classifications flow correctly into the return.

For passive investors in mobile home park partnerships, understanding how cost segregation flows through on the K-1 is also essential. See our guide to MHP accounting for passive investors for more on this topic.
