The Mobile Home Park Valuation Formula

There's one formula that drives nearly every mobile home park sale price. Here's how it works—and a real example you can follow.

The Formula That Rules MHP Valuations

If you want to know what your park is worth, there is one formula that matters above all else:

Park Value = NOI ÷ Cap Rate

That's it. That one formula drives the vast majority of mobile home park transactions. Whether you're selling to an individual investor, a family office, or an institution, this is what they're calculating in the background.

Let's break down what each part means:

Understanding Each Variable

NOI: Net Operating Income

NOI is the money your park actually makes. It's your total annual rent minus all operating expenses (property taxes, insurance, maintenance, utilities, payroll, etc.)—but before paying any debt service or taxes.

If your park collects $300,000 in rent and spends $120,000 operating it, your NOI is $180,000. That's the number that goes into the numerator of the formula.

Cap Rate: Capitalization Rate

The cap rate is the annual return an investor expects to earn. It's expressed as a percentage. If an investor buys a park for $2.5 million and expects to earn 6% annually on that capital, the cap rate is 6%.

Different parks command different cap rates depending on risk. A newer park in a strong market might be bought at a 5.5% cap rate. A smaller rural park might sell at 8.5%. The better the park, the lower the cap rate—which paradoxically means a higher sale price (since you divide by a smaller number).

A Complete Worked Example

The Park: 72 Lots in the Midwest

Let's value a mid-size mobile home park with the following characteristics:

Step 1: Calculate Gross Income

Lot rent: 65 lots × $375/month × 12 months = $292,500

Other income: $1,500/month × 12 months = $18,000

Total Gross Income = $310,500

Step 2: Account for Vacancy

Vacant lots: 7 × $375/month × 12 months = $31,500

Gross Income after vacancy: $310,500 − $31,500 = $279,000

Step 3: Subtract Operating Expenses

Annual operating expenses: $9,583/month × 12 = $115,000

NOI = $279,000 − $115,000 = $164,000

Step 4: Apply the Cap Rate

Now we know the park generates $164,000 in NOI. What's it worth? That depends on what cap rate the market is paying. For this park—a Class B property in a stable market—let's assume a 6% cap rate:

Park Value = $164,000 ÷ 0.06 = $2,733,333

So this park is worth approximately $2.73 million.

How Cap Rate Affects Price

Notice that same $164,000 NOI, but change the cap rate:

Same park, same income, but small changes in cap rate swing the value by hundreds of thousands of dollars. This is why the quality of the park matters so much—it determines what cap rate buyers are willing to accept.

How Changing One Variable Moves Your Price

Let's use the same park ($164,000 NOI, 6% cap rate, $2.73M value) and see what happens when you make operational improvements:

Scenario A: Raise Rents by $25/Lot

Additional annual income: 65 occupied lots × $25/month × 12 = $19,500

New NOI: $164,000 + $19,500 = $183,500

New Park Value: $183,500 ÷ 0.06 = $3,058,333

Increase in value: $325,000

Scenario B: Fill 5 More Vacant Lots

Additional annual income: 5 lots × $375/month × 12 = $22,500

New NOI: $164,000 + $22,500 = $186,500

New Park Value: $186,500 ÷ 0.06 = $3,108,333

Increase in value: $375,000

Scenario C: Reduce Expenses by $10,000/Year

New NOI: $164,000 + $10,000 = $174,000

New Park Value: $174,000 ÷ 0.06 = $2,900,000

Increase in value: $166,667

Key insight: Every $1,000 increase in annual NOI adds $16,667 to your park's value (at a 6% cap rate). This is why improving operations before selling is so powerful. Small improvements in income or efficiency can add hundreds of thousands to your final sale price.

Why This Formula Is Used Instead of Comparable Sales

You might ask: why not just look at what similar parks sold for, like with houses? There are two good reasons:

There Aren't Enough Comps

Mobile home parks don't trade frequently. In many markets, only a handful of parks sell in a year. And each park is different—different lot count, different locations, different infrastructure. Finding true "comparables" is nearly impossible.

Income Is What Buyers Really Care About

A park is fundamentally different from a house. You don't buy a mobile home park to live in it. You buy it to earn income from lot rents. So the only thing that really matters to a buyer is how much cash that park generates each year. The formula captures that directly.
