If you’re looking at mobile home parks as an investment, one of the first things you need to understand is how to calculate the value of a mobile home park. Unlike single-family homes, mobile home parks aren’t valued based on comparable sales. They’re valued like businesses — based on the income they produce.

This guide walks you through the key formulas, metrics, and real-world considerations that determine what a mobile home park is actually worth.

The Income Approach: How Mobile Home Parks Are Valued

Mobile home parks are commercial assets, which means they’re valued using the income approach. The basic formula is simple:

Property Value = Net Operating Income (NOI) ÷ Capitalization Rate (Cap Rate)

For example, if a mobile home park generates $150,000 in annual NOI and the market cap rate is 7%, the value is:

$150,000 ÷ 0.07 = $2,142,857

That’s the core of it. But the devil is in the details — how you calculate NOI and what cap rate you use makes all the difference.

Step 1: Calculate Gross Potential Income

Start with the total income it could generate if every lot were occupied and every tenant paid on time.

• Lot rent: This is the primary revenue driver. Multiply the monthly lot rent by the total number of lots, then multiply by 12. Example: 80 lots × $350/month = $28,000/month = $336,000/year.
• Park-owned home (POH) rent: If the mobile home park owns some homes and rents them out, include that rental income separately. Note that POH income is generally valued at a higher cap rate (lower value per dollar) because it comes with more management overhead and risk.
• Utility income: If you bill back water, sewer, or trash to tenants, include that revenue.
• Other income: Late fees, application fees, laundry facilities, storage units, RV pads.

Step 2: Subtract Vacancy and Collection Loss

No mobile home park runs at 100% occupancy with 100% collections. You need to account for reality.

• Vacancy rate: If 10 of your 80 lots are empty, that’s 12.5% vacancy. Deduct that from gross income.
• Collection loss: Even occupied lots don’t always pay on time. Budget 2–5% for delinquency and bad debt, depending on the market and tenant quality.
• Effective Gross Income = Gross Potential Income − Vacancy Loss − Collection Loss

Step 3: Calculate Operating Expenses

Operating expenses include everything it costs to run the property on a day-to-day basis. Do not include debt service (mortgage payments) or capital expenditures — those are not operating expenses.

Typical mobile home park operating expenses include:

• Property taxes: Usually the single largest expense. Verify with the county — don’t rely on the seller’s number, as taxes often increase after a sale.
• Insurance: Property and liability coverage. Costs have been rising 15–25% annually in many markets.
• Utilities: Water, sewer, electric for common areas, street lights. If the property is on a master meter, this can be significant.
• Management: Whether self-managed or third-party, budget 8–10% of collected revenue for management.
• Maintenance and repairs: Roads, common areas, infrastructure. Budget at least $50–$100 per lot per year for routine maintenance.
• Legal and accounting: Eviction costs, lease preparation, annual accounting.
• Trash removal: If not billed back to tenants.
• Payroll: On-site manager, maintenance staff.

A well-run mobile home park typically has an expense ratio of 35–45% of effective gross income. If the seller’s numbers show 20–25%, they’re either not reporting all expenses or deferring maintenance — both of which cost you later.

Step 4: Determine Net Operating Income (NOI)

NOI = Effective Gross Income − Total Operating Expenses

Let’s run through a real example:

• 80 lots at $350/month = $336,000 gross lot rent
• Utility billback income = $24,000/year
• Other income = $6,000/year
• Gross Potential Income = $366,000
• Less 10% vacancy = ($33,600)
• Less 3% collection loss = ($10,980)
• Effective Gross Income = $321,420
• Less 40% operating expenses = ($128,568)
• NOI = $192,852

Step 5: Apply the Right Cap Rate

The capitalization rate reflects the market’s required rate of return for that type of asset in that location. It’s essentially a measure of risk — higher cap rate = higher perceived risk = lower price per dollar of income.

Typical mobile home park cap rates in 2026:

• 5–6% cap: Institutional-quality mobile home parks in strong MSAs. City utilities, 200+ lots, 95%+ occupancy, long-term tenant base.
• 6.5–7.5% cap: Mid-market properties in decent locations. 50–200 lots, city water/sewer, some value-add opportunity.
• 8–10%+ cap: Smaller or rural mobile home parks, private utilities, higher vacancy, significant operational risk.

Using our example NOI of $192,852:

• At a 6% cap: $192,852 ÷ 0.06 = $3,214,200
• At a 7% cap: $192,852 ÷ 0.07 = $2,755,028
• At an 8% cap: $192,852 ÷ 0.08 = $2,410,650

That one-point difference in cap rate swings the value by nearly $800,000. This is why understanding your local market’s cap rate — and being able to defend your assumption — is critical in negotiations.

The Value-Add Equation: Where Wealth Is Created

The real power of mobile home park investing is the value-add play. Because mobile home parks are valued on income, every dollar of NOI you add gets multiplied by the cap rate.

Consider this: you raise lot rents by $50/month across 70 occupied lots.

• Additional annual income: 70 × $50 × 12 = $42,000
• Value created at a 7% cap: $42,000 ÷ 0.07 = $600,000

A $50/month rent increase just created $600,000 in equity. That’s the math that makes mobile home parks one of the most compelling asset classes in real estate.

Other common value-add strategies:

• Filling vacant lots: Each occupied lot adds $4,000–$6,000+ in annual NOI, which translates to $60,000–$85,000+ in value at a 7 cap.
• Billing back utilities: Sub-metering water and billing tenants directly can add $30–$60/lot/month in recovered expenses.
• Reducing expenses: Renegotiating vendor contracts, improving collections, or transitioning from POH to TOH all improve NOI.

Common Valuation Mistakes to Avoid

• Using the seller’s pro forma NOI: Always value based on current, verified income — not what the seller says it could be. You should pay for what the property is, not what it might become.
• Ignoring deferred maintenance: A mobile home park with a low expense ratio and crumbling infrastructure isn’t efficient — it’s a time bomb. Budget for deferred CapEx in your acquisition price.
• Applying residential cap rates: mobile home park cap rates are different from apartment or single-family cap rates. Use mobile home park-specific market data.
• Overvaluing POH income: Institutional buyers often apply a 10–12% cap rate to POH income vs. 6–7% for lot rent income. Don’t blend them at the same rate.
• Forgetting post-sale tax reassessment: Property taxes frequently increase after a sale. Model the reassessed tax amount, not the current one.

The Bottom Line

Mobile home park valuation comes down to a simple framework: what is the verified NOI, and what cap rate does the market assign to that income stream? Master those two variables and you can evaluate any deal that crosses your desk.

The investors who build the most wealth in this space are the ones who buy mobile home parks where they can meaningfully grow NOI through lot rent increases, infill, and operational improvements — then watch the value multiply through the cap rate.
