Here is a conversation we have all the time. An owner tells us the building is "doing fine." Occupancy is decent, the bank is paid, nobody is yelling. Then we look at the trailing twelve months and find a few thousand dollars a month quietly leaking out the side: units that sat empty an extra week, rents that were never moved, a trash contract nobody has looked at since the last owner signed it.
That is the honest answer to how to increase NOI. It is rarely one big move. It is a pile of small corrections that all point the same direction, and because of how buildings are valued, each one is worth more than it looks.
Why NOI gets so much attention
Net operating income is what's left of your rents and other income after you pay the costs of running the building. It leaves out your loan payment, depreciation and income taxes, which is why it works as a clean measure of how the property performs on its own.
It also sets the price. Buyers and lenders value income-producing property by dividing NOI by a capitalization rate, the return the market expects for that kind of asset. We won't go deep on the rate itself here, since it deserves its own article. For this one, you only need the arithmetic.
Value is roughly NOI divided by the cap rate. Raise the top number and the whole answer moves.
Say your building produces $300,000 in NOI and similar buildings trade at a 6% cap rate. That puts the value near $5,000,000. Now say you find $30,000 more NOI. At the same rate, the value moves to $5,500,000. You earned $30,000 a year, and you created $500,000 in value.
Those numbers are examples, not a forecast for any building. But the shape is real, and it changes how you should think about a $60-a-unit utility fee or a three-day improvement in turn time. On a 40-unit building, $62.50 per unit per month is $30,000 a year. Small things, multiplied by twelve months and by the number of units, then by the cap rate.
One caution before we go on. The goal is durable NOI, income you can keep. A building that hits a great number by skipping repairs and running its staff ragged will pay for it within a year or two. Everything below is meant to hold up.
How to increase NOI starts with finding the gap
Before you change anything, find out where you actually stand. Pull the last twelve months of income and expenses, the current rent roll, and your budget if you have one. Then ask three questions.
How does each line compare with the same line last year? How does it compare with similar buildings nearby? And which lines are larger than anyone can explain?
That last one is where the money tends to be. If your repairs line jumped 30% and no one remembers a big project, find out why. If your water bill is far above what a building your size should run, something is leaking, running or being billed wrong.
Good reporting makes this part easy. If you can't answer those questions from the package you receive each month, that is the first problem to fix, and our piece on what a good owner report should include walks through what you should be seeing.
Revenue: the rent you are not collecting
Most owners think of revenue as one number, rent. It is really five or six smaller levers, and each one has its own fix.
Occupancy and the cost of a vacant day
Vacancy is the most expensive thing in your building, and it hides in plain sight. If your average rent is $1,500 a month, a vacant unit costs about $50 a day. A 40-unit building with 20 turns a year that sits vacant ten days longer than it should is losing about $10,000 a year ($50 × 10 days × 20 turns). In that example, that is $10,000 of NOI, or about $167,000 of value at a 6% cap rate.
Another way to see it: one percentage point of occupancy on 40 units at $1,500 is about 0.4 of a unit, worth roughly $7,200 a year.
The causes are usually process, not market. Notice of move-out arrives late. The unit isn't marketed until it is empty. The turn takes a week longer than it should because the painter and the cleaner can't coordinate. Leads wait until the next morning for a reply. We fix these by working backward from the day a resident gives notice: list the unit early, schedule the turn before the keys come back, and answer every inquiry fast. Speed to lead matters more than most owners expect, and it is one of the places technology earns its keep.
Loss to lease
Loss to lease is the gap between what your residents pay and what a new resident would pay for the same unit today. It builds up quietly. Rents move in the market, but your older leases stay where they were signed.
Say 10 of your units are on leases $50 below what you would charge a new resident. That gap is $6,000 a year. You won't close all of it at once, and you shouldn't. Pushing renewals too hard can push good residents out the door, and a turn costs far more than a few months of an underpriced lease. The craft is in setting each renewal offer based on the unit, the resident's history and the market, not applying one blanket increase to everyone.
Concessions
Concessions are rent you give away to win a lease. One month free on a 12-month lease sounds like a one-time cost, but it works out to about an 8% discount on the full year, and it often sets the next rent too. If you're concession-driven, ask a harder question than "should we offer one?" Ask what is making the unit hard to lease. Photos, price, a stale listing, a slow response, a unit that doesn't show well. Fixing the cause is almost always cheaper than discounting around it.
Other income
This is the most underused lever in small and mid-size buildings. Other income is anything beyond base rent:
- Utility billing, where residents pay a share of water, sewer or trash
- Pet fees and monthly pet rent
- Parking, covered spaces and storage
- Late fees, application fees and renewal fees where your lease and local rules allow them
- Package lockers, laundry, and other amenity charges
A few illustrations, all example numbers. Billing back $30 a month for utilities across 38 occupied units is about $13,680 a year. Eight pets paying $35 a month is $3,360. Ten storage lockers at $40 a month is $4,800. None of these are huge on their own. Together they're roughly $21,800, which at a 6% cap rate is a little over $360,000 of value.
Two cautions. First, whatever you bill must be written into the lease and handled in line with Nevada rules, so have your attorney review the language before you change anything. Second, don't stack so many fees that your all-in cost beats the building across the street. Residents compare total monthly cost, and they notice when a low rent comes with a pile of extras.
Pricing that moves
Many small owners set rents once or twice a year by feel. Strong operators price every unit on its own, using what's available, what's coming due and how fast similar units are leasing right now. This is where real data pays off. If you are not looking at competitors, your own lead volume and your days on market every week, you're pricing blind.
Renewals are where rent actually moves
Most of your rent growth happens at renewal, not at move-in, so treat renewals as a process instead of a letter. Start the conversation early, around 90 to 120 days out, so you know who is planning to stay before you decide what to offer. Look at what a new resident would pay for the unit today, how long this resident has been with you, and what a turn would cost if they left. Then make the offer.
Here is a rule of thumb we like. If a turn would cost you six to eight weeks of rent between vacancy, make-ready and marketing, a modest increase on a good resident is a better deal than a large one that sends them to the apartments down the road. Say the market allows $75 more on a $1,500 unit. Taking $50 and keeping the resident beats taking $75 and losing them, as long as your turn math looks anything like the example above.
Expenses: the savings that are in your control
Revenue depends on the market. Expenses depend mostly on you, which is why we like to start here with new clients. The rule is simple: cut waste, not service.
Utilities
Water and sewer are often the biggest line and the most fixable. A running toilet or a leaking irrigation line can waste money for months before anyone notices. Check the meter against your own records monthly, look for usage spikes, and fix leaks the week you find them. Low-flow fixtures and smarter irrigation scheduling cost little and keep paying. For common-area electricity, lighting upgrades and timers are an easy win.
Turns and repairs
Turn costs add up fast, and they vary a lot from one unit to the next. The fix is a consistent scope. Decide what a standard turn includes, price it with your vendors in advance, and track every turn against it. When one unit runs far over, you want to know why. If your turn cost drops by $300 across 20 units, that is $6,000 a year, with no impact on the resident's experience.
Preventive maintenance belongs here too. A water heater replaced on your schedule costs less than one that fails on a Saturday night.
Service contracts
Landscaping, trash, pest control, elevator service, snow removal if you need it. Every one is a recurring contract, and nobody likes reading them. So they renew themselves for years. Rebid them every two or three years. Get at least three quotes, compare scope as well as price, and negotiate. If you save $500 a month on trash and recycling by rebidding, that is $6,000 a year of NOI for a few phone calls.
Property taxes
Taxes are a big line, and they aren't set in stone. In Washoe County, the Assessor's Office values real property each year and publishes how to petition the County Board of Equalization if you disagree with your assessed value; the Washoe County Assessor's site lists the appeal and petition links. Deadlines are strict, so check the current calendar early.
Not every appeal is worth filing. It helps to compare your assessed value with what the building's income and recent comparable sales support. If you suspect an overvaluation, you might ask your CPA or a property tax professional to review it. As an example, on a $60,000 tax bill, an 8% reduction is $4,800 a year, and it usually repeats.
Insurance
Insurance costs have climbed in many markets, and many owners simply accept the renewal. Don't. Ask your broker to market the policy, look at deductibles and coverage limits, and fix the things underwriters care about, like roof condition, old wiring, security and claims history. A cleaner risk profile gets better quotes.
Payroll and staffing
Staffing is the easiest place to cut in a way that backfires. Understaffing a property shows up as slow turns, unanswered leads and unhappy residents, and all of those cost more than the saved salary. The better question is how to make each person more productive: self-guided tours, online maintenance requests, automated reminders and clearer routines. This is another place where technology and process do the work that headcount used to do.
Savings that backfire
Not every cut is a saving. Deferring a roof repair, dropping the pest contract or putting off a boiler service moves cost from this year to next year, usually with interest. The same goes for delaying turns to save on make-ready, or trimming landscaping until the curb appeal starts costing you leads.
A good test: if the cut would show up in a resident survey, a bad review or an inspector's report, it isn't a saving. It is a loan against your future NOI, and a careful buyer will find it during due diligence.
What it can add up to
Here is how those example levers stack up on a 40-unit building. Every number is illustrative. None of it is a promise or a projection for a specific property.
| Lever | Example annual NOI change |
|---|---|
| Utility bill-back, 38 units at $30 a month | $13,680 |
| Pet rent, 8 pets at $35 a month | $3,360 |
| Storage lockers, 10 at $40 a month | $4,800 |
| Close part of loss to lease, 10 units at $50 | $6,000 |
| One point of occupancy, 40 units at $1,500 | $7,200 |
| Turn savings, 20 turns at $300 | $6,000 |
| Trash contract rebid, $500 a month | $6,000 |
| Property tax reduction, 8% of a $60,000 bill | $4,800 |
| Total | $51,840 |
At a 6% cap rate, $51,840 of added NOI points to roughly $864,000 of value. The point is not the total. The point is that no single line in that table feels dramatic, and no construction is involved.
Let the data do the nagging
Owners who raise NOI steadily rarely do it with heroic effort. They do it because the building tells them, every week, where it is slipping. A leasing dashboard shows how many inquiries became tours and how fast you answered them. A work order system shows which units eat the most repair dollars. A rent roll that flags leases expiring in the next 120 days tells you exactly whom to call about a renewal.
That is the practical value of technology in a building this size. It does not replace judgment, it tells you where to spend it. If a unit has taken 40 days to lease and the one next to it took nine, there is a reason, and the numbers get you to the question in a minute instead of a quarter.
If you only track one thing beyond the monthly financials, make it days vacant per turn. It combines your marketing, your pricing, your maintenance crew and your vendors into a single number that rises the moment something goes wrong. When we look at a building for the first time, it is usually the first number we ask for, and it often points us to the problem before we have opened a single contract.
You also want a clear line of sight between your plan and your results. Pick the three or four levers you are actually pulling this quarter, write down the number you expect each one to move, and check it in ninety days. Owners who do this learn quickly which ideas pay and which only feel productive. Owners who don't tend to run a lot of projects and wonder why NOI looks the same as last year. Knowing how to increase NOI is mostly a habit of measuring what you changed.
Where capital belongs in a plan to increase NOI
Some NOI gains do require capital: interior upgrades, new fixtures, better curb appeal, a laundry room that finally works. The question is always the same. Does the added rent, or the avoided cost, pay back the spend fast enough, and does it still pencil out if rents come in lower than you hoped?
We cover that process in detail in our guide to value-add multifamily. The short version: fix operations first, because a renovated unit in a badly run building rarely hits its rent target.
Build the habit, not just the plan
A one-time cleanup helps. A monthly rhythm helps more. Look at the same handful of numbers every month: occupancy and days vacant, loss to lease, other income per unit, turn cost and days, and your big expense lines against budget. When a number moves the wrong way, ask why while it is still small.
That is also what to expect from whoever runs your building. If you are still deciding who that should be, our guide on how to choose a property management company covers what separates a company that reports numbers from one that moves them.
A 90-day starting plan
If you want to start this week, here is the order we would work in.
- Pull your trailing twelve months and rent roll. Mark every line that grew faster than income, and every unit priced below what a new resident would pay.
- Time your turns. Count the days from notice to move-in on the last ten, and find where the time goes.
- Read your leases and your other income. List what you could bill for and aren't, and have your attorney check the wording before anything changes.
- Rebid your three largest service contracts and ask your broker to market the insurance.
- Check your assessed value against the income and sales evidence, and mark the appeal deadline on your calendar.
- Set renewal offers for the next 120 days, one unit at a time.
If you want a partner on the numbers, our multifamily consulting team starts in the same place: the trailing twelve months, the rent roll and a plain conversation about where the money is.
