Underwriting a mobile home park (MHP) is vastly different from underwriting an apartment building or a single-family home. Because you are primarily in the infrastructure and land business, the metrics that matter most are often hidden beneath the surface.<\/p>\n\n\n\n

If you underwrite incorrectly, you risk buying a “money pit” disguised as a cash-flowing asset. Here is the professional framework for underwriting a mobile home park with precision.<\/p>\n\n\n\n

1. The Golden Rule: Separate Lot Rent from Home Rent<\/h2>\n\n\n\n

The most common mistake beginners make is “globalizing” the income. They take the total rent collected and apply a standard cap rate. This is a fatal error.<\/p>\n\n\n\n

In a professional MHP underwriting model, you must separate income into two buckets:<\/p>\n\n\n\n

\u2022Lot Rent: This is the stable, high-value income derived from the land. This is what you apply your market cap rate to.<\/p>\n\n\n\n

\u2022Home Rent (POH): Income from Park-Owned Homes is volatile, high-maintenance, and depreciates. You should typically value POH income at a massive discount (often 2x-3x annual earnings) or value the homes separately as personal property.<\/p>\n\n\n\n

“Never pay a ‘land cap rate’ for ‘home rent.’ You are buying two different businesses: a real estate business and a trailer rental business.”<\/p>\n\n\n\n

2. The Expense Ratio Reality Check<\/h2>\n\n\n\n

While a well-run park might have a 30-40% expense ratio, you must underwrite for the reality of the infrastructure. If the seller claims a 20% expense ratio, they are likely deferred-maintenance specialists.<\/p>\n\n\n\n

Key expense benchmarks to include:<\/p>\n\n\n\n

\u2022Property Management: 7-10% (even if you manage it yourself, underwrite for a professional).<\/p>\n\n\n\n

\u2022Repairs & Maintenance: $200-$400 per lot per year for infrastructure.<\/p>\n\n\n\n

\u2022Water\/Sewer: If not sub-metered, this is your largest and most volatile expense.<\/p>\n\n\n\n

\u2022Property Taxes: Don’t use the seller’s current tax bill. Underwrite for the re-assessed value based on your purchase price.<\/a><\/p>\n\n\n\n

3. The Infrastructure Audit (The “Underground” Risk)<\/h2>\n\n\n\n

In an apartment, you check the roof. In a park, you check the pipes. Your underwriting must account for the type and condition of the utilities:<\/p>\n\n\n\n

\u2022Master-Metered vs. Direct-Billed: If the park is master-metered for electricity or gas, you are taking on utility risk. Underwrite for the cost of sub-metering or the potential for massive leaks.<\/p>\n\n\n\n

\u2022Septic vs. City Sewer: Septic systems are “ticking time bombs” in underwriting. If the park is on septic, you must budget for frequent pumping and eventual replacement.<\/p>\n\n\n\n

\u2022Pipe Material: If the park has “Orangeburg” or thin-wall PVC pipes, you should budget for a total line replacement within your hold period.<\/p>\n\n\n\n

4. Market Analysis: The “Lot Rent vs. 2-Bedroom Apartment” Test<\/h2>\n\n\n\n

How much can you actually raise the rent? To underwrite the “upside,” compare the total cost of living in your park (Lot Rent + Home Payment) to the cost of a 2-bedroom apartment in the same submarket.<\/p>\n\n\n\n

If the park’s total cost is less than 50% of a local apartment, you have significant “runway” to increase lot rents. If the gap is narrow, your ability to grow NOI is capped.<\/p>\n\n\n\n

5. Occupancy and “Ghost” Lots<\/h2>\n\n\n\n

Don’t just look at the number of pads; look at the economic occupancy.<\/p>\n\n\n\n

\u2022Vacant Pads: Do they have utilities? Are they overgrown<\/a>? Bringing in a new home can cost $40,000+. Underwrite the capital expenditure (CapEx) required to fill every vacant lot.<\/p>\n\n\n\n

\u2022Abandoned Homes: These are liabilities, not assets. Underwrite the cost of removal or renovation.<\/p>\n\n\n\n

Conclus\u00e3o<\/h2>\n\n\n\n

Correct MHP underwriting is about de-risking the downside. By separating home income from lot income, accounting for infrastructure “surprises,” and benchmarking against the local housing market, you can identify the true value of a park.<\/p>\n\n\n\n
