When investors look for ways to improve a mobile home park, they often focus on raising lot rents or filling empty lots. However, one of the most overlooked opportunities sits right on the expense side of the ledger: utilities. Water and sewer costs, in particular, can quietly drain net operating income year after year. Fortunately, utility billback and submetering may offer a practical way to recover those costs and potentially strengthen a mobile home park’s value-add strategy and overall bottom line.

Why Utilities Weigh So Heavily on a Mobile Home Park

In many mobile home parks, water and sewer sit among the largest line items on the profit and loss statement. Moreover, these costs rarely stay flat. Across many markets, water and sewer rates have climbed roughly 8–15% year over year, and some communities have reported increases of 25–30% over just five years. As a result, an owner who absorbs these costs faces a moving target that tends to shrink margins over time.

The Master-Metered Challenge

Older mobile home parks, especially those built before 1980, often run on a single master meter. In this setup, the owner receives one consolidated bill from the municipality, while residents pay a flat lot rent and see no direct link between their usage and their cost. Consequently, consumption in master-metered communities can run noticeably higher — some estimates suggest 20–40% above individually metered properties. In short, the owner essentially provides unlimited water with no built-in incentive for anyone to conserve.

How Utility Billback and Submetering Work

Two common approaches can shift some of this burden back toward the people who actually use the utilities.

Submetering

With submetering, the owner installs an individual meter at each home. Therefore, each resident pays for the exact amount of water they use. This method creates a clear price signal, and it also helps surface hidden leaks that might otherwise go unnoticed for weeks.

Ratio Utility Billing Systems

Alternatively, a Ratio Utility Billing System (RUBS) allocates the master bill among residents based on factors like occupancy or home size, rather than actual usage. While RUBS can help recover costs, research suggests it may not reduce consumption in a meaningful way, since residents still lack direct feedback on their own use.

The Potential Value-Add Impact

Recovering More of the Bill

When billing reflects actual usage, owners tend to recover a larger share of their utility costs. Industry estimates suggest that RUBS arrangements often recover roughly 70–85% of costs, while submetered properties may recover 90–95% or more once billing stabilizes. In practice, utility billback can add somewhere in the range of $50–$100 per lot per month back to effective income, depending on the market and the local rate structure.

Encouraging Conservation

Billing for actual usage also appears to change behavior. According to EPA WaterSense data, submetering has been associated with water consumption reductions of roughly 15–40% in multifamily settings. Furthermore, a two-year study cited by the EPA found statistically significant savings of about 15.3%, or roughly 21.8 gallons per day per home. By comparison, RUBS showed no statistically significant reduction in that same research.

Translating Savings Into Value

Because mobile home parks are typically valued on net operating income, even modest expense reductions may influence value. Consider a simplified example: a 50-lot community paying $3,000 per month for water and sewer. If submetering reduces usage by around 25%, the master bill might fall to roughly $2,250 per month, and the owner could bill residents for much of the remaining amount. Over time, a large portion of that expense may move off the owner’s ledger. While no outcome is guaranteed, that kind of shift can meaningfully affect net operating income — and, by extension, the potential value of the mobile home park.

Important Considerations Before You Begin

Naturally, this strategy involves more than installing meters and sending invoices. Before moving forward, owners generally need to weigh several factors.

Local Regulations

Some states and municipalities limit how, or whether, owners can bill back utilities. Always check the rules first.

Infrastructure

Aging or shared plumbing can complicate installation and may require upgrades before metering becomes practical.

Upfront Cost

Meters, billing software, or third-party billing services all carry expenses that affect the payback timeline.

Resident Communication

Residents tend to accept fair, usage-based billing more readily when owners explain the change clearly and give reasonable notice.

Final Thoughts

Utility billback and submetering will not solve every challenge in a mobile home park, and results can vary widely from one community to the next. Even so, this lever offers a rare combination: it may reduce a major expense, promote conservation, and improve the accuracy of cost recovery all at once. For investors exploring the mobile home park asset class, understanding utility billback is a meaningful step toward evaluating where hidden value might exist. As always, careful due diligence and local guidance remain essential before making any decisions.
