Cap Rate vs Cash-on-Cash Return: What MHP Investors Actually Use to Evaluate Parks

New MHP investors often come to the table with one number in mind: the cap rate. They’ve heard that mobile home parks trade at certain cap rates, they have a target, and they’re looking for deals that fit. That’s a reasonable starting point. But it’s only half the picture.

The cap rate tells you about the asset’s income relative to its price. The cash-on-cash return tells you about your actual return on the money you put in. Those are two very different questions, and the answers diverge significantly when financing is involved — which, for most MHP acquisitions, it is.

Understanding both metrics, calculating them correctly, and knowing how depreciation distorts the relationship between cash return and taxable income is foundational knowledge for any serious MHP investor. Let’s work through each one.

Cap Rate: What the Asset Earns on Its Own

The capitalization rate (cap rate) is the simplest valuation metric in commercial real estate. It answers one question: if you bought this property all-cash, what would your return be?

The formula is straightforward:

Cap Rate = Net Operating Income (NOI) / Purchase Price

If a park generates $120,000 of annual NOI and is listed for $1,800,000, the cap rate is 6.67% ($120,000 / $1,800,000).

The cap rate is entirely independent of financing. It doesn’t matter whether you put 20% down or 50% down or buy it all-cash — the cap rate is the same. That’s what makes it useful as a valuation and comparison metric. You can compare a park in Texas at a 7-cap to a park in Florida at a 5-cap on an apples-to-apples basis, regardless of how either deal would be financed.

Cap rates are also used in reverse: if you know what cap rate the market assigns to parks in a given area, you can calculate implied value by dividing your NOI by that cap rate. A park with $200,000 NOI in an 8-cap market is worth $2,500,000. The same park in a 6-cap market is worth $3,333,333. Market cap rate movement is one of the most powerful (and risky) forces in MHP value — see our post on how to calculate NOI correctly before you trust any cap rate computation.

The Critical Rule: What Belongs in NOI

The cap rate is only as good as the NOI calculation. The most common errors MHP buyers make when evaluating a park:

• Including debt service in expenses: Mortgage payments are not an operating expense. NOI is calculated before debt service. Adding your mortgage payment to expenses before calculating cap rate produces a meaningless number.
• Using gross revenue instead of NOI: Dividing the purchase price by gross rent rolls produces a “gross rent multiplier,” not a cap rate. Gross revenue includes nothing about expenses — it tells you nothing about what the asset actually returns.
• Omitting management expense: Even if you self-manage, NOI should include a market-rate management expense. A cap rate calculated on a self-managed basis without management expense is artificially high — it doesn’t represent the asset’s income if a professional manager is hired, which affects both your own underwriting of management burnout risk and how a future buyer values the park.
• Including depreciation in expenses: Depreciation is a tax deduction, not a cash expense. It does not belong in the NOI calculation. NOI is a cash-based metric.
• Including capital expenditures: Replacing a water line or a community building is not an operating expense. CapEx belongs in a separate reserve analysis, not in NOI. However, a CapEx reserve is a real cost of ownership that should inform your overall return analysis.

Cash-on-Cash Return: What Your Money Earns

The cash-on-cash return (CoC) answers a different question: given the actual financing structure of this deal, what is the annual cash return on the equity I invested?

The formula is:

Cash-on-Cash Return = Cash Flow Before Tax (CFBT) / Total Equity Invested

Cash Flow Before Tax is NOI minus debt service (principal and interest payments on your loan). Total equity invested is your down payment plus closing costs plus any immediate capital improvements required at acquisition.

To continue the example above: the park has $120,000 NOI. You put $540,000 down (30% of $1,800,000) and your annual debt service on the remaining $1,260,000 at current rates is $85,000. Your CFBT is $120,000 – $85,000 = $35,000. Your CoC return is $35,000 / $540,000 = 6.5%.

The CoC return is entirely financing-dependent. The same park with different financing produces a different CoC. This is why CoC is not useful for comparing parks to each other (use cap rate for that) but is essential for evaluating whether a specific deal works for you given your specific financing terms.

The Difference Between Buying at a 5-Cap vs 8-Cap

Cap rate reflects both income yield and market perception of risk and growth potential. A 5-cap MHP is priced higher relative to its income than an 8-cap park. Why would a buyer pay more (accept a lower yield)?

Lower cap rates (higher prices relative to income) are typically associated with:

• Stronger markets with higher demand and lower vacancy risk
• Higher lot rents with demonstrable below-market upside
• Infrastructure quality that suggests lower near-term CapEx
• Larger park size and institutional-quality operations
• Parks in states with more favorable landlord laws

Higher cap rates (lower prices relative to income) are associated with:

• Smaller, rural, or less liquid markets
• Management-intensive parks with operational risk
• Deferred maintenance or infrastructure that requires capital
• Higher concentration of park-owned homes (more management complexity)
• Markets with regulatory risk or rent control exposure

Neither is universally better. An 8-cap park in a recovering market with operational upside may be a better investment than a 5-cap park in a stable market with no rent growth potential. The cap rate is the starting point — understanding what drives it is the work.

How Depreciation Affects Your Cash-on-Cash vs Taxable Income

Here’s where MHP investing gets genuinely interesting from a tax perspective. A park can generate strong cash-on-cash return while simultaneously showing a taxable loss on your tax return. Depreciation is why.

Depreciation is a non-cash deduction that reduces your taxable income but has no effect on your actual cash flow. An MHP with significant personal property (POHs on 5-year MACRS), 15-year land improvements, and a cost segregation study can generate substantial depreciation deductions in early years of ownership — often exceeding the park’s cash flow.

The result: you receive strong cash distributions, and your K-1 shows a taxable loss. That loss may be usable against other passive income you have, carried forward to future years, or (if you qualify as a real estate professional under IRC §469) usable against ordinary income. See our post on passive vs active income classification for MHP owners for how these losses are used.

This is why evaluating an MHP investment on cash-on-cash return alone misses a significant component of total return. The after-tax return — which accounts for the tax benefit of depreciation — is often substantially higher than CoC alone suggests. Your CPA should model this before you decide whether a specific deal clears your hurdle rate.

The Metric That Combines Both: Total Return

Sophisticated MHP investors look beyond CoC to total return — which includes cash flow, principal paydown (equity buildup through amortization), appreciation, and tax benefit from depreciation. Each of these components contributes to your actual wealth creation from the investment, and optimizing for CoC alone can lead to undervaluing parks with strong appreciation potential or significant depreciation benefits.

For new investors building their analytical framework, the order is: understand NOI, calculate cap rate correctly, model CoC for your specific financing, then layer in tax benefit from depreciation. The full picture gives you a defensible answer to the question every MHP investor needs to answer: is this deal worth buying at this price?

Before evaluating any park, make sure you have the correct foundation. Review how to calculate NOI correctly and understand the tax due diligence checklist that should accompany any acquisition.
