Multifamily Deal Water Bill

Let’s say I am underwriting a 10-unit apartment property. The rents make sense for the market, occupancy is stable, and nothing in the first pass through the income causes concern. I move into the multifamily operating expenses expecting to confirm that the property deserves a deeper look, and then I get to water.

The most recent bill is $2,400.

On a 10-unit property, that is enough to make me slow down, not because I have already decided the property has a serious problem, but because the number does not fit what I expected to see. Over the years, I have learned that unusual numbers deserve attention before they deserve an explanation. When something falls outside the pattern, I want to understand why before I allow the answer to influence my underwriting.

That is a big part of learning to analyze multifamily well. The work is not only about calculating whether the deal meets your return targets. It is also about knowing when a number deserves a second look and being patient enough to stay with the question until the property starts making sense.

Start by Finding the Pattern

One month, by itself, does not tell me much. I want to know what water normally looks like at this property.

Suppose the previous four months were $1,140, $1,185, $1,210, and $1,160. Now the $2,400 bill has context. The earlier months are relatively consistent, which means May is clearly outside the normal range.

At that point, I have a useful question, but I still do not have an answer.

The seller may tell me there was a leak. That may be true, but I am not going to remove the expense from the underwriting simply because the explanation sounds reasonable. I would want to see the utility statements, the repair invoice, the work order, or something else that connects the story to what actually happened at the property.

This is not about being difficult or assuming anyone is misleading me. It is about understanding what I am buying well enough to make a sound decision.

A T12 can show me that the property spent $2,400 on water. It cannot always tell me why. That usually requires another layer of investigation, and that is where the numbers begin turning into useful information instead of simply being entries on a spreadsheet.

The Same Expense Can Mean Two Very Different Things

Assume the seller produces an invoice showing that a main-line leak occurred during May. The repair was completed, and the next bill drops back into the historical range. Now I have a consistent story: several normal months, one unusual expense, documentation explaining what happened, and evidence that the issue was corrected.

I would view that very differently from a property where water has been climbing for six months, management cannot explain why, and there is no repair history or plan in place to correct the problem.

The dollar amount may look similar on the financial statement, but the operating reality is completely different.

That distinction matters because a recurring expense can have a much larger effect on the investment than one difficult month. If water had historically averaged around $1,175 but the property began spending $2,400 every month, the difference would be roughly $1,225 monthly, or about $14,700 per year.

On a small multifamily property, that is meaningful NOI. At a 7 percent cap rate, $14,700 of annual NOI represents roughly $210,000 in value.

That does not mean I would see one high bill and immediately subtract $210,000 from the purchase price. The point is that a small operational question can become a large investment question when the issue repeats month after month. Understanding whether the expense is temporary or recurring changes how I view both the cash flow and the risk in the deal.

Here is how those two situations compare, using the same numbers from this example:

How I Would Treat the Water Expense

By the time I finish investigating, I want the evidence to point me toward a reasonable conclusion rather than forcing the underwriting to carry an assumption I cannot support.

What I am trying to separate here is the difference between what exists today and what I believe I may be able to improve later. Both matter, but they should not be blended together simply because the future version of the property makes the deal look better.

Be Careful How Quickly You Turn a Problem Into Upside

Once an investor identifies a weak expense, it is very easy to begin solving the problem before the property has even been purchased.

The high water bill becomes a plan for low-flow fixtures, better leak detection, utility reimbursement, stronger management, or a plumbing upgrade. All of those could become legitimate parts of the business plan, and I absolutely believe strong operations can create value where another owner has left money on the table.

The important part is timing.

If the owner currently pays all of the water, then that expense exists today. If I intend to implement reimbursement, I need to understand whether I can do it, how long it will take, what the leases allow, and what portion of the expense can realistically be recovered. If I believe management can reduce the bill, I still need to know what is causing the current usage before I assume the savings are achievable.

That is where the quality of the underwriting matters. There is the property as it operates now, and there is the property I believe I can create through better execution. A good business plan connects those two versions with evidence, time, and realistic assumptions.

I would rather buy a property that works based on the information I can support and then create additional value through good operations than purchase one that only works if every improvement happens exactly the way I hoped.

The Investigation Can Tell You More Than the Expense

The water bill itself may turn out to be a minor issue. The process of investigating it can still tell me a great deal about how the property has been operated.

If management immediately knows what caused the increase, provides the bill and repair record, and has already reviewed the next month’s usage, that tells me they are paying attention.

If nobody noticed the expense doubled until I asked, there are no useful records, and management has no idea why the cost changed, I have learned something very different.

At that point, I am no longer evaluating only the water bill. I am learning about maintenance oversight, financial reporting, management quality, and how quickly operating problems are identified and addressed.

This is why I like to follow the number that does not fit. A strange expense can uncover deferred maintenance, weak reporting, poor management, or a recurring problem that the current owner has simply learned to live with. It can also confirm that the property is being operated well and an isolated issue was handled appropriately.

Either result makes the underwriting better because I understand the business more clearly than I did before I started asking questions.

Frequently Asked Questions

Should one unusually high expense make me walk away from a multifamily deal?

No. One unusual expense is a reason to investigate, not necessarily a reason to reject the property. I want to know whether the cost was temporary, recurring, correctable, or part of a larger operating issue before deciding how much weight it should carry in the investment decision.

When can I normalize an expense in my underwriting?

I am comfortable adjusting an expense when there is enough evidence to support the change. Historical bills, repair invoices, maintenance records, and subsequent statements can help establish what normal operations actually look like. I would not remove an expense simply because the seller describes it as unusual.

Should I include future utility reimbursements in the deal?

I prefer to separate current performance from future opportunity. If residents are not reimbursing utilities today, I do not treat that income as though it already exists. Once I verify that reimbursement is realistic and can be implemented properly, I can include it as part of the business plan rather than current operations.

Does this same process apply to expenses other than water?

Absolutely. Insurance, repairs, payroll, trash, taxes, landscaping, and other operating expenses can all contain numbers that deserve a closer look. What matters is understanding why the number is different and whether that difference is likely to continue.

Find the Number That Does Not Fit

When I review a property, I am not only looking for the numbers that confirm what I already like about the deal. I am also looking for the places where the financial story stops making sense.

It could be water. It could be insurance that appears unusually low, repairs that suddenly dropped during the year the owner decided to sell, collections that do not match the rent roll, or payroll that seems too light for the level of service the property requires.

Those are the places where I slow down.

At Ignite RE Wealth, this is part of what I want investors to develop through Multifamily Investing Training. Knowing how to calculate NOI matters, but knowing when a number deserves another question is what begins turning analysis into judgment.

A $2,400 water bill may turn out to be nothing more than a repaired leak. It could also be the first clue that the property is operating very differently from the story you were originally given. The value is understanding which one you are looking at before the property becomes yours.
