Everyone talks about buying more units. More doors, more deals, more capital raised, bigger portfolio. And look, I get it — I’ve bought over 6,000 units. Growth is exciting.
But here’s something I’ve learned that most people figure out too late: some of the best returns you’ll ever get come from the portfolio you already own.
Your existing tenants are recurring monthly customers. They’re already sold. They already live there. The question is whether you’re capturing everything you could from that relationship — and whether you’ve done the work to make sure the property itself is operating at its highest level.
Here’s how I think about it.
Ancillary Revenue: What You’re Probably Leaving on the Table
When I talk about increasing income from an existing tenant base, I’m not talking about squeezing people. I’m talking about offering services and amenities that tenants actually want and are happy to pay for.
Valet trash. This is one of the simplest ancillary revenue streams in multifamily. You hire a vendor to pick up trash from each unit’s door a few nights a week, charge tenants $20 to $30 a month for the service, and keep the spread. Tenants love it because it’s convenient. You love it because it’s $20 to $30 a month per unit in additional income that goes almost entirely to the bottom line. At a 6% cap rate, $25 a month per unit across a 50-unit building is an extra $15,000 a year in income — which adds $250,000 in property value.
Pet fees and pet rent. I allow pets in my properties because I harden them — LVP flooring, stone countertops, durable surfaces that don’t absorb damage the way carpet and laminate do. That means pets can’t cause the kind of damage they can in a softer unit. In exchange for allowing pets, we charge a one-time $200 deposit per pet and $25 to $50 per month in pet rent. At a 58-unit building, if even 20% of tenants have a pet, that’s roughly $550 a month in additional revenue. Over a year, at a 6% cap rate, that increases enterprise value by around $110,000. From something that costs almost nothing to implement.
Parking. If your property has parking, charge for it. Indoor spaces in markets with cold winters command a premium. Covered parking in hot climates commands a premium. At minimum, assigned outdoor parking at $50 to $75 a month per space is a clean income stream that most operators undercharge for or give away free. On a building with 30 parking spaces, that’s $1,500 to $2,250 a month — over $25,000 a year — that may not exist in your current rent roll.
Amenity add-ons. Fitness facilities, clubhouse access, tutoring services, community gardens — depending on your market and tenant demographic, there are amenities tenants will pay for monthly that cost relatively little to operate. At one of our properties near a school, we offer after-hours tutoring in the clubhouse. Parents whose kids come home to an empty apartment while they’re still at work will pay for that. It’s a real service. It generates real revenue. And it’s not something any other apartment building in that area offers.
The key with all of these is that the income goes straight to NOI. You’re not adding units. You’re not taking on new debt. You’re increasing the income on an asset you already own, which increases both your cash flow and your enterprise value.
The Five Expense Lines Worth Attacking
On the other side of the ledger, every dollar you pull out of expenses is worth exactly as much as a dollar of new income — and it often requires a lot less effort.
There are five main expense categories in multifamily: property taxes, insurance, utilities, maintenance, and management. Here’s where I focus.
Property taxes. If your assessed value is higher than what the property is actually worth, or higher than comparable properties in the area, appeal it. This is not complicated and it’s something most operators never do. I’ve had tax appeals produce five and six-figure annual reductions on individual properties. Hire a firm that specializes in property tax appeals — they typically work on contingency, so you only pay if they get a reduction. Also, before you buy anything, ask the local municipality about tax abatement or exemption programs. In some cities, significant capital improvements to a property can trigger a 10 or 15-year tax abatement. That’s a competitive advantage that translates directly to NOI.
Insurance. Shop your policy annually with an independent broker. Ask your insurer what they see as the highest-risk elements of your property and what capital improvements would lower the premium. I replaced old breaker boxes on a 36-unit building for $18,000 and saved $20,000 a year in insurance costs. Ask about master policies — there’s a reason large operators get significantly better rates. And audit your current coverage for things you’re paying for that don’t apply to your property or don’t actually protect you in the scenarios you’d actually care about.
Utilities. If you’re in a deregulated state, shop your energy suppliers. The default rate from the utility company is rarely the best rate available. On the water side, low-flow toilets, showerheads, and faucets reduce consumption by up to 40% annually. LED lighting in common areas typically cuts electric bills by 25%. These are capital investments with fast payback periods and permanent ongoing savings.
Maintenance. The biggest lever here is hardening the property upfront so ongoing maintenance is minimal. LVP flooring instead of carpet — easier to clean, faster to turn, no shampooing. Flush-mount lights instead of ceiling fans — one less moving part to break, dangle, or make noise. Stone or quartz countertops instead of laminate — more durable, looks better to prospective tenants, doesn’t burn or peel. Annual mechanical maintenance on HVAC units and water heaters extends their life by at least 50% and prevents expensive emergency replacements. The best maintenance program is the one that makes most maintenance unnecessary.
Management. Every dollar you save on management expenses — whether by bringing management in-house, improving your management company’s performance, or eliminating the waste that comes from disconnected systems and reactive decision-making — goes straight to your bottom line. And at a 6% cap rate, every $10,000 in annual expense reduction adds $166,000 in property value.
The Math That Matters
On a 100-unit property at $1,000 per month average rent, you have $1.2 million in gross potential revenue. A 50% expense ratio puts your NOI at $600,000 and your property value at $10 million at a 6% cap rate.
Now add $30 per unit per month in valet trash and pet rent across 80% of units. That’s $2,400 a month, $28,800 a year. At a 6% cap rate, that’s $480,000 in added property value.
Cut $50,000 in annual expenses through insurance savings, utility reductions, and better maintenance practices. That’s another $833,000 in property value.
Neither of those required buying a single new unit. They required paying attention to what you already own.
Before you go raise money for the next deal, look hard at the portfolio you have. There’s almost certainly more value there than you’re currently capturing.
Smart Management tracks ancillary revenue, expense ratios, and NOI across every property in your portfolio in real time, so you can see exactly where the opportunity is without waiting for a month-end report. See how it works.
