Why the way you categorize expenses determines what you can actually manage – and what stays invisible forever.

The VP of Asset Management at a 6,000-lot mobile home park operator got a question from ownership on a Tuesday morning: maintenance costs at a community were up 22% year over year. What’s driving it?
Her analyst pulled the P&L. Repairs and maintenance was up – no question. He opened the account. Everything was in there together: work orders on park owned homes, asphalt repairs on the interior roads, a water line replacement on the east loop, routine landscaping. The community ran a mix of park owned homes and tenant owned homes, but the chart of accounts made no distinction between them. POH unit repairs, TOH lot maintenance, common area work, and infrastructure spend all rolled into the same GL account.
There was no way to tell from the P&L whether the cost increase was coming from the POH side – homes the operator owned and was responsible for maintaining – or from the land and infrastructure side that would exist regardless of home ownership structure. Those are two different problems with two different solutions. The COA treated them as one.
He spent the better part of two days pulling work orders from the property management system, sorting them by type in a spreadsheet, and building a manual breakdown. By the time the answer landed – it was three park owned homes generating 40% of the unit-level service calls, all homes the operator had acquired with the community – ownership had already moved on to the next issue.
The data was there the whole time. The chart of accounts just had no way to show it.

Not all manufactured housing operators are the same

Before we talk about what a chart of accounts should look like, it helps to be specific about what kind of operator you are – because the answer is genuinely different depending on your strategy and your portfolio composition.

The first distinction that matters is whether your communities include park owned homes (POH), tenant owned homes (TOH), or both.

TOH-POH

The manufactured housing industry, which according to the Manufactured Housing Institute represents more than 22 million Americans living in manufactured homes today, encompasses a wide range of operating models. The first distinction that matters for your chart of accounts is whether your communities include park owned homes (POH), tenant owned homes (TOH), or both.

In a TOH community, the resident owns the home and you own the land. You collect lot rent. Your operating model is relatively simple – land, infrastructure, and common area. In a POH community, you own both the land and the homes. You collect home rent, you carry the asset on your balance sheet, and you are responsible for maintenance at the unit level. These are two different businesses running inside the same fence line. They have different revenue structures, different expense profiles, and different paths to value creation. A chart of accounts that treats them as one operation is already working against you.

The second distinction is your current strategic mode. Most MH operators are in one of three:

Value-Add

Value-add operators have recently acquired a distressed or undermanaged asset and are actively improving it – filling vacant lots, repairing infrastructure, improving management, repositioning the community. This phase is capital-intensive and operationally complex. You need to track every improvement dollar carefully, separate capital expenditures from operating expenses, and monitor progress against a specific business plan.

Rent Growth

Rent growth operators are running a stabilized portfolio. Occupancy is solid, the asset is performing, and the focus is pushing rents annually while holding the expense ratio flat. The reporting challenge here is different – you need visibility into what is driving expense creep so you can protect your margin as revenue grows.

Exit Prep

Exit prep operators are managing toward a sale or refinance. The priority is clean, credible NOI that holds up to a buyer’s or lender’s scrutiny. Any structural messiness in your financials – misclassified expenses, inflated revenue from home sales, inconsistent treatment across properties – gets re-casted at the table. That recast costs you money.

Why your chart of accounts probably doesn’t match your strategy

Most MH operators set up their chart of accounts once – when they bought their first property – using whatever their accountant suggested, their property management system defaulted to, or a previous employer used. Then the business evolved. They added POH. They acquired more communities. They started managing toward an exit. The strategy changed. The chart of accounts didn’t.

The result is an accounting structure that records money accurately but generates almost no useful management information. You can close the books. You cannot run the business from them.

A well-designed chart of accounts is a direct expression of your strategy. It encodes what questions matter to you. And a chart of accounts that doesn’t match your current strategy will reliably hide the answers to your most important questions.

Three places this breaks down in practice

The utility bucket problem is the most common and the most fixable. Gas, water, and electric expenses collapsed into one “Utilities” GL account. You can see the total spend. You cannot see which utility is rising, which community has an infrastructure problem, or whether your submetering program is actually reducing water expense. The data exists in your invoices. Your chart of accounts ate it. Each utility should be its own account – and in a portfolio of any size, each should be breakable by community.

The POH and TOH maintenance blind spot is more consequential. When maintenance expenses are pooled across both home types, you lose the ability to see what your POH program actually costs to operate. If you’re a value-add operator trying to evaluate whether to convert POH to TOH – selling the homes to residents and transitioning to lot rent – you need to know what POH maintenance is running you per unit. If that number lives inside a general repairs account alongside roads, common areas, and infrastructure, your analyst is rebuilding it from invoices every time you ask. That is not an analyst problem. That is a COA problem.

Home Sales

The home sales misclassification is the one with direct financial consequences at exit. When proceeds from selling a park owned home to a resident are booked as operating revenue, your NOI looks higher in years with active home sales. A buyer or lender will recast it. More importantly, you are making ongoing management decisions against a NOI number that includes a capital event – which means you may be misreading your own operating performance for months or years before anyone notices. Home sale proceeds belong below the NOI line, separately from recurring operating revenue.

The test worth running right now

Pull your current chart of accounts. Then ask: does this structure let me answer the questions my strategy is actually asking?

If you are in value-add mode, can you see capital spend by project and community – separate from operating expenses?

If you are in rent growth mode, can you see which specific expense category is rising, in which community, and at what rate?

If you are in exit prep mode, does your P&L match how a buyer will underwrite it – or will their first recast be a surprise?

If you run POH alongside TOH, can you see the economics of each program separately?

Most operators, when they run this test honestly, find that their chart of accounts was built for a version of their business that no longer exists.

That is not a small problem. It is the reason your data feels frustrating – not because you don’t have enough of it, but because the structure you’re using to organize it was designed to answer different questions than the ones you’re asking now.

RentViewer helps leading manufactured housing owner operators keep track of their KPIs and run their business with good, readily-usable data. We can help you present your data in the structure your current strategy actually needs. But the COA has to be right first. Clean data through a broken structure is still a broken view.
