If you’re evaluating a mobile home park investment, one of the most important documents you’ll review is the mobile home park profit and loss statement — also called a P&L. This financial report tells you exactly how much money the park generates, where it goes, and whether the deal makes sense. Knowing how to read it is a foundational skill for every serious investor.

In this guide, we’ll walk through each section of a typical mobile home park P&L, explain what healthy numbers look like, and highlight the red flags that can turn a promising deal into a costly mistake.

Why the P&L Statement Matters in Mobile Home Park Investing

The P&L is the foundation of your underwriting. It feeds directly into your Net Operating Income (NOI) calculation, which determines the park’s value based on the prevailing cap rate. A park with strong, clean financials commands a premium. A park with inflated or incomplete financials is a risk — and a negotiating opportunity if you know what to look for.

The key thing to understand: sellers don’t always present P&Ls that are investor-ready. You may get QuickBooks exports, spreadsheets, or tax returns. Your job is to normalize the numbers — strip out non-recurring items, add back owner perks, and identify missing expenses — to arrive at the true economic picture.

Revenue Line Items to Understand

A mobile home park’s income statement starts with revenue. Here are the key categories:

Lot Rent Income

This is the core revenue driver. Each occupied lot pays a monthly lot rent. To verify: multiply occupied lots × monthly lot rent × 12. Example: 100 occupied lots × $135/month × 12 = $162,000 per year. If the P&L doesn’t match this math, ask why.

Park-Owned Home Rent

If the park owns any homes and rents them out, that income appears separately. Park-owned homes generate higher gross revenue but also carry higher operating costs — repairs, vacancies, turnover, and management overhead. Watch for parks where park-owned home income masks poor lot occupancy.

Utility Income

If the park is on a master meter and sub-meters each lot, residents may pay the park for water, sewer, gas, or electric. This can be a meaningful revenue stream — but confirm the corresponding utility expense to ensure the park isn’t losing money on the spread.

Late Fees and Other Income

Late fees, application fees, and miscellaneous charges typically make up a small slice of revenue. These are legitimate but high late fee income can signal resident financial distress or high turnover.

Operating Expenses You Should Expect

A well-run mobile home park typically operates at a 30–45% expense ratio (expenses as a percentage of gross revenue). Sellers often understate expenses. Your job is to reconstruct a realistic expense load before calculating NOI.

• Property taxes: Often one of the largest single expenses. Verify with the county assessor — don’t rely solely on what the seller reports.
• Insurance: Confirm current policy cost. Rates have risen significantly in 2025–2026.
• Utilities (common area): Street lights, water for vacant lots, community well or pump maintenance.
• Management fees: If the owner is self-managing, add a market-rate management fee — typically 8–10% of gross revenue — to normalize for professional management. Skipping this is one of the most common underwriting errors.
• Maintenance and repairs: Budget $500–$1,500 per occupied lot annually, depending on park age and infrastructure condition.
• Administrative costs: Bookkeeping, legal, office supplies, property management software.
• Capital expenditure reserve: Budget 3–5% of revenue for cap-ex. Our guide to mobile home park capital expenditure planning covers this in depth.

Red Flags on a Mobile Home Park P&L

Artificially Low Expense Ratios

A P&L showing only a 10–15% expense ratio almost certainly has missing expenses. Common omissions: management fees, property taxes, insurance, and maintenance reserves. Always reconstruct to normalized operating expenses before trusting any NOI figure a seller provides.

Revenue from Park-Owned Homes Hiding Occupancy Issues

A park with 70 lots but only 50 lot-rent-paying residents might look fine if the other 20 are park-owned homes generating rent. But when you strip out those homes — which often carry deferred maintenance and unpredictable turnover costs — the underlying lot occupancy picture changes significantly.

Income Spikes Before Sale

Sellers sometimes postpone maintenance or push through rent increases right before listing. Always request 2–3 years of P&Ls. Look for sudden expense drops or revenue jumps in the year before the sale.

Missing Standard Expense Categories

If property taxes, insurance, or management don’t appear on the P&L — those aren’t expenses the park doesn’t have. They’re expenses the seller didn’t include. Add them back into your underwriting before you do anything else.

How to Calculate NOI from the P&L

Net Operating Income is the cornerstone of mobile home park valuation. Once you’ve normalized the P&L, the math is straightforward:

NOI = Total Revenue − Total Operating Expenses

For our 100-lot example: $180,000 in total revenue minus $72,000 in operating expenses (40% ratio) equals a NOI of $108,000. At a 7% cap rate, that supports a valuation of approximately $1.54 million. At 6%, that same NOI is worth $1.8 million. Every dollar of normalized NOI matters enormously at the negotiating table.

What a Healthy Mobile Home Park P&L Looks Like

A well-run mobile home park P&L typically shares these characteristics:

• Expense ratio of 30–45% of gross revenue (institutional parks run closer to 35–40%)
• Stable or growing revenue over a 3-year period — not spiking only in the year of sale
• Utilities properly sub-metered or billed back to residents, reducing park exposure to cost swings
• Management fee included at market rate, even if the park is currently owner-managed
• Maintenance expense that reflects actual park age and condition, not artificially suppressed
• No unusual one-time income that inflates the trailing 12-month revenue picture

Final Thoughts

Reading a mobile home park profit and loss statement comes down to one discipline: normalize before you underwrite. Add back missing expenses, question inflated income, and arrive at a realistic NOI that reflects how the park will actually perform under your ownership. That number drives your valuation, your offer price, and your returns.

The investors who master this skill build durable portfolios. The ones who skip it often learn expensive lessons they could have avoided with a few extra hours of careful analysis.
