The Master Bill Is Not the Cost of Doing Business. It Is a Leak.
Here is a conversation we have a lot. An owner says, "Utilities are just included. That's how we've always done it. Guests like it." Then we look at the summer electric bill, and the water bill, and the number of monthly guests running two air conditioners all day. The owner gets quiet.
Unmetered utilities are one of the most common glitches in mom-and-pop parks, and one of the most fixable. This page explains why they matter so much when you sell, what buyers will look at, and how to turn a leak into value you can actually show.
Why Utilities Matter at Sale
A park is valued on its net operating income, the money left after operating expenses. Every dollar of utility cost you absorb and do not recover comes straight out of that number.
Then a buyer applies a cap rate to that income to get a price. That multiplies the effect. Simple illustration, not a promise about your park: if a buyer values a park at a 9 percent cap rate, every $10,000 of yearly net income is worth roughly $111,000 of price. So $10,000 a year of unrecovered utilities can quietly cost you around that much at sale. Bigger leaks, bigger numbers.
That works in your favor too. Utility recovery is one of the few improvements that can raise net income without adding a single site. That is the heart of "the glitch is the equity."
Buyers also look at utilities for a second reason: capacity. High, unrecovered usage often goes hand in hand with stressed electrical systems and septic systems running past their design. Water in is wastewater out.
What Buyers and Lenders Will Scrutinize
Documents they will ask for
- 12 to 24 months of every utility bill: electric, water, sewer, trash, propane, internet. Two years shows seasonality.
- How each site is billed: included in rent, flat fee, metered and billed back, or split by formula.
- Sub-meter details if you have them: what is installed, how readings are taken, how guests are billed.
- Recovery reports: what you billed guests for utilities each month versus what you paid.
- Guest agreements that spell out utility charges for monthly and seasonal stays.
Tests they will run
- Cost per occupied site per month, and how it swings summer to winter.
- Recovery ratio: what percentage of your utility cost you actually collect back.
- Winter base-flow check on water. High water use in the slow season can point to a leak.
- Usage vs. septic design flow, to see if water use is pushing the septic system past its permit.
Red flags that move price
- "Utilities included" on long-term sites with big summer bills.
- Utility recovery mixed into rent, so nobody can see it.
- Water use that does not drop much in the off-season.
- Meters installed but never read, or readings never billed.
- Billing practices that do not match local rules.
What to Check, Fix, and Document
1. Line up the bills
Get two years of every utility bill into one folder or spreadsheet. Put summer and winter side by side. Most owners have never seen it laid out this way, and it is eye-opening.
2. Figure out what you are actually recovering
Look at what guests paid you for utilities each month, if anything. Divide by what you paid the utility. That is your recovery ratio. Write it down, even if it is zero.
3. Check the rules before you change anything
Sub-metering and billing guests for electric or water is regulated differently from place to place. Some areas allow billing actual usage at cost. Some have specific rules on rates, notices, or meter types. Call your utility and check with your state or local authorities, and have your attorney look at your guest agreements before you start billing.
4. Choose the right tool for your park
- Sub-meters on each site measure real use. This is the clearest proof for a buyer, where allowed.
- Formula billing (sometimes called RUBS, ratio utility billing) splits the bill by a formula. It can be a useful bridge, but it is an estimate, and buyers know it.
- Flat utility fees on monthly sites are better than nothing, but they still leave you exposed in a hot summer.
Get quotes from qualified installers and a licensed electrician or plumber for the work.
5. Start the record early
A buyer will credit a utility recovery program that has a track record. One month of billing is a promise. Twelve months is proof. If you are planning to sell in a year or two, the best time to start is now.
6. Hunt down leaks
If winter water use is high, find out why. A running leak wastes money and can overload your septic system. Fix it and keep the invoice.
Get-Ready-for-Sale Checklist
- 24 months of all utility bills in one place
- Summer vs. winter comparison for electric and water
- Current billing method listed for every site
- Monthly recovery ratio calculated
- Local and utility rules on sub-metering and billing confirmed
- Guest agreements updated by your attorney to cover utility charges
- Quotes for sub-meters or a formula billing setup
- Meter reading and billing schedule written down and followed
- Utility recovery recorded as its own revenue line, never folded into rent
- Winter water use checked for leaks, and repairs documented
Common Mistakes
- Folding utilities into rent. It makes rent look high and hides the leak. Buyers pull it apart anyway.
- Calling a formula a cure. It helps. It is not the same as metered proof.
- Installing meters and never billing. Equipment without a record is not value.
- Starting billing a month before you sell. No track record, little credit.
- Changing utility charges without notice or legal review. That can create guest disputes and legal exposure right when you need calm.
- Ignoring the capacity side. Heavy water use is a septic story too.
An Example
Illustrative example. Composite of situations we see; details and numbers changed.
A couple running a park with a growing number of monthly guests included electric and water in every rate. Their electric bill in late summer ran more than double the winter bill. They figured that was normal.
When they laid out two years of bills, they saw that almost all the summer increase came from the monthly loop. They checked their local rules, had their attorney update guest agreements with proper notice, and installed electric sub-meters on the monthly sites. They kept water on a flat fee while they priced water meters.
A year later they had twelve months of meter readings and billing records showing most of the monthly electric cost recovered. When buyers looked, that recovery was in the T-12 as its own line, backed by the bills. It was income a buyer could underwrite, not a pitch about "upside."
