How Mobile Home Park Exit Value Is Calculated

The single most common mistake in mobile home park (MHP) underwriting is treating the exit like an apartment building — one stabilized Net Operating Income (NOI) divided by one cap rate. That works for multifamily because the entire revenue stream comes from one thing: renting out housing units the owner provides. Mobile home parks are different. A park is often two businesses fused into one property: a land-lease business (lots rented to homeowners) and, sometimes, a rental-home business (park-owned homes rented like apartments). These streams behave differently, lenders treat them differently, and an honest exit-value calculation values them separately.

This article walks through the separated-stream exit model, why it's the standard for serious MHP buyers and lenders, and what an underwriter gets wrong by collapsing the two streams into one.

The Two Income Streams in Plain Terms

Lot income is what residents pay for the right to keep their home on a piece of land the owner controls. It's recurring, low-maintenance from the owner's side, and durable — once a home is on a lot, moving it is expensive and rare. Lot income is the closest thing in commercial real estate to a perpetual ground lease.

Park-owned home (POH) income is what residents pay to rent a home the park owns. The economics look more like a rental-housing business: the owner is on the hook for the roof, the appliances, and the make-ready when a tenant leaves. The home is a depreciating asset with a finite useful life, not durable real estate.

These are fundamentally different revenue streams. A buyer will generally pay more per dollar of lot NOI than per dollar of POH NOI, because lot income is more durable, less capital-intensive, and more financeable. Mixing them in an exit calculation tends to misprice the deal — either undervaluing lot income or overvaluing POH income.

The Separated-Stream Exit Model

The exit-value calculation that many lenders, brokers, and disciplined buyers use follows directly from the two-stream premise:

Exit value = (Exit-year lot NOI ÷ Exit cap rate) + (Number of POH × Per-home exit value)

The lot NOI gets capitalized at a land-style cap rate. The park-owned homes get added on flat, at a per-home value reflecting what a comparable home is actually worth at sale — not capitalized like real estate.

Why flat instead of capitalized? Because the POH stream isn't perpetual. The homes wear out, require capital to maintain, and have a finite useful life. Capitalizing POH income as if it were real estate income tends to overstate value, which is why many MHP lenders won't underwrite POH on a capitalized basis. Per-home resale values vary by market and vintage and should reflect the local market for that condition of home — actuals vary significantly by submarket.

A Worked Example

Consider an 80-lot park with 10 park-owned homes, a five-year hold, and the following exit-year inputs:

• Exit-year lot NOI: $272,000
• Exit cap rate (lots): 7.0%
• POH count: 10
• Exit value per POH: $25,000

Lot component: $272,000 ÷ 0.07 = $3,886,000 POH component: 10 × $25,000 = $250,000 Gross exit value: $4,136,000 Less 3% selling costs: ($124,000) Net sale proceeds: $4,012,000

Now suppose an underwriter — used to multifamily — capitalizes everything together. If POH NOI is, say, $40,000 and they include it in the capitalized stream at the same 7% cap rate, they would add roughly $571,000 to the exit value. That is about a $321,000 overstatement (the difference between $571,000 capitalized and the $250,000 flat value). On a roughly $4M exit, that is an error of around 8% — enough to swing deal IRR by hundreds of basis points and convince a committee to approve a deal that does not actually work. (Figures here are illustrative; individual deals vary by market, vintage, and operator.)

Why Lenders Anchor to This Model

When a lender underwrites a mobile home park, its analysis tends to split the income the same way. Agency programs (Fannie Mae's and Freddie Mac's manufactured-housing community programs) and many regional banks will typically:

1. Capitalize the lot income at a land-style cap rate to set the underwritten value;
2. Discount or exclude POH income from loan sizing, depending on the program and how seasoned the POH operation is;
3. Treat the POH inventory as personal property, not real estate collateral.

These details are subject to change — verify current terms directly with the lender or agency. The implication for an equity underwriter is direct: if an exit value relies on a buyer capitalizing POH income alongside lot income, it has built in an assumption the buyer's lender may not share. That gap can surface at closing, when financing terms force the buyer to pay less than the model expected. Underwriting to the lender's framework from the start helps avoid that surprise.

The Common Mistakes — and How to Catch Them

A few traps worth watching for, in your own work and in others':

1. Capitalizing POH income. The headline issue. If a pro forma shows a single NOI capitalized at a single cap rate, check whether POH is inside that NOI. If it is, the exit is likely overstated.

2. Using going-in cap as exit cap. Cap rates are not static. As a base case, the exit cap is often set equal to or modestly above going-in (cap expansion), with compression reserved for theses that can be defended. This is true across commercial real estate but matters more in MHP, where spreads can be wide.

3. Forgetting vacancy and management at exit. Year-five NOI should reflect realistic stabilized vacancy and a market-rate management fee, not optimistic ones. Buyers will normalize these in their own underwriting.

4. Ignoring deferred capex. A park with imminent infrastructure replacement (water lines, road resurfacing, sewer lift station) will tend to sell for less than a clean park with the same NOI. Reflect the capex in the exit value or build a reserve into the NOI that will otherwise be capitalized away.

5. POH exit value detached from market reality. A flat per-home value well above what comparable homes resell for is not conservative — it's wrong. Tie the per-home value to actual market evidence.

The Bottom Line

Mobile home parks reward buyers and sellers who understand they are trading in two distinct businesses bundled together. Capitalize the durable lot income at an honest cap rate, value the park-owned homes flat at what they are really worth, expand the exit cap unless compression can be shown, and reflect deferred capex before the buyer's diligence does it first. Get the structure right and the exit number is more likely to hold up when a lender's underwriter — and an LP's analyst — runs the same math.
