The Hidden Costs of Being a Landlord: What Nobody Tells You Before You Buy

By PropsManager Team · Rent & Finance · Jul 22, 2024

I remember the napkin math on my first rental property. $1,400 in rent, $950 mortgage payment. That's $450 a month in profit, right? Easy money.

That was twelve years ago. The actual profit that first year? About $127 a month, once I tallied everything up. And that was a good year — nobody moved out and nothing major broke.

Here's the truth that real estate gurus on YouTube won't tell you: the gap between gross rent and actual profit is enormous, and it's filled with expenses most new landlords never see coming. If you're thinking about buying your first rental property — or you already own one and can't figure out why you're barely breaking even — this guide will walk you through every hidden cost that eats into your bottom line.

The Dangerous "Rent Minus Mortgage" Myth

Every new investor does the same calculation. They pull up Zillow, find a property, estimate the rent, subtract the mortgage, and declare themselves future millionaires. I've seen it hundreds of times on landlord forums, and I've watched it end badly just as often.

The National Association of Realtors estimates that operating expenses on a rental property typically consume 35% to 80% of gross rental income, depending on property age, location, and management style. That means on a property pulling in $1,800 a month, you might only net $360 to $1,170 — before debt service.

Real investors use a metric called Net Operating Income (NOI), and they account for every dollar that leaks out between what the tenant pays and what lands in your pocket. Let's break down exactly where that money goes.

Vacancy: The Expense That Pays You Nothing

Why 100% Occupancy Is a Fantasy

No rental property stays occupied 365 days a year, every year. Tenants move. Leases end. Sometimes you have to evict someone. According to the U.S. Census Bureau, the national rental vacancy rate hovers around 6.4%, though it varies wildly by market — some Sun Belt cities run under 4%, while older Midwest markets can push 10% or higher.

Here's what vacancy actually costs you on a $1,500/month rental:

• One month vacant per year: $1,500 lost rent + $950 mortgage you still pay = $2,450 total impact
• Two months vacant: $3,000 lost rent + $1,900 in mortgage = $4,900 hit

And that doesn't include the utilities you're paying on an empty unit, the lawn care, the snow removal, or the extra insurance rider some carriers require for unoccupied properties.

How to Budget for Vacancy

Most experienced landlords budget 5% to 8% of gross rent for vacancy. On $1,500/month, that's $75 to $120 set aside every single month the unit is occupied, so you have a cushion when it's not. If you're in a market with high turnover or your property targets transient demographics (college towns, military bases), bump that to 10%.

PropsManager's financial tracking features can automatically calculate your effective vacancy rate across your entire portfolio, so you're never guessing.

Capital Expenditures: The Big Stuff That Breaks

The Ticking Clock on Every Major System

CapEx — capital expenditures — refers to the big-ticket replacements you know are coming but hope won't arrive anytime soon. Every major system in a rental property has a lifespan, and when it expires, you're writing a check with a lot of zeros.

Here's what typical replacement costs look like:

The Monthly CapEx Reserve

Smart landlords set aside roughly 5% to 10% of monthly rent for CapEx. On a $1,500/month property, that's $75 to $150 per month going into a dedicated reserve account. It doesn't feel like much until you realize that over five years, you've banked $4,500 to $9,000 — which just might cover that new HVAC unit when the compressor finally gives up in August.

If you skip this step, you're one broken furnace away from putting $7,000 on a credit card at 24% interest. I've been there. Don't be there.

Turnover Costs: Death by a Thousand Paper Cuts

Every time a tenant leaves, it costs you money. Even if they were perfect tenants who left the place in great shape, there's still a checklist of expenses before the next person moves in.

The True Cost of a Single Turnover

Here's a realistic breakdown for a standard 2-bedroom apartment turnover:

• Paint touch-up or full repaint: $400–$1,200
• Professional deep cleaning: $200–$400
• Carpet cleaning or replacement: $150–$1,500
• Lock re-keying: $75–$150
• Minor repairs (patch drywall holes, fix cabinet hardware, replace outlet covers): $100–$300
• Listing photos and marketing: $0–$300
• Leasing agent commission (if applicable): one half to one month's rent
• Vacancy during turnover (typically 2–4 weeks): $750–$1,500

Add it all up. A basic turnover easily runs $1,500 to $3,000. A rough one — where the tenant trashed the place or you need new flooring — can hit $5,000 to $8,000 without blinking.

According to the National Apartment Association, the average turnover cost for an apartment unit is approximately $4,000 when you factor in lost rent and make-ready expenses. And the average renter stays just 27.5 months, which means you're eating this cost more often than you'd like.

Reducing Turnover Expenses

The cheapest turnover is the one that doesn't happen. Keeping good tenants happy is worth far more than squeezing an extra $50 out of a rent increase that pushes them to leave. A few strategies:

• Respond to maintenance requests quickly and professionally
• Offer modest renewal incentives ($25/month discount, a minor upgrade)
• Communicate proactively — tenants who feel heard stick around longer
• Use a platform like PropsManager to automate lease renewals and tenant communication, removing friction from the process

Maintenance and Repairs: The Constant Drip

Separate from CapEx (planned replacements), there's ongoing maintenance — the stuff that breaks randomly and needs fixing now. A running toilet. A leaky faucet. A garbage disposal that sounds like it's eating silverware. A dryer vent clogged with lint.

The 1% Rule

A widely used benchmark: budget 1% of the property's value annually for maintenance and repairs. On a $250,000 property, that's $2,500 a year, or about $208 per month. Older properties or those in harsh climates may need 1.5% to 2%.

This doesn't cover CapEx. This is in addition to your CapEx reserve. Yes, it adds up fast. That's the point — most new landlords dramatically underestimate maintenance costs and then panic when reality hits.

Seasonal Maintenance You Can't Skip

Some maintenance isn't optional — it's preventive, and skipping it costs you more later:

• Spring: HVAC tune-up ($80–$150), gutter cleaning ($100–$200), exterior inspection
• Summer: Landscaping and pest control ($50–$100/month), check window seals and caulking
• Fall: Furnace inspection ($80–$150), weatherstripping, drain winterization
• Winter: Ice dam prevention, pipe insulation checks, snow removal ($100–$300/month in cold climates)

Skip the fall furnace inspection and you might end up replacing the whole system in January. Ask me how I know.

Insurance Gaps: What Your Policy Doesn't Cover

Your standard landlord insurance policy covers the structure, liability, and maybe loss of rent. But there's a list of things it probably doesn't cover that could wipe you out.

Common Coverage Gaps

• Flood damage: Not included in standard policies. A separate flood policy runs $700–$2,000/year depending on your zone.
• Sewer backup: Often excluded. A rider costs $50–$100/year and is worth every penny.
• Mold remediation: Many policies exclude or cap mold coverage. Remediation for a serious mold problem can run $10,000–$30,000.
• Tenant-caused damage beyond the security deposit: Your insurance won't cover it. The deposit might cover $1,500. The damage might be $8,000.
• Loss of rent (extended vacancy): Some policies only cover 6–12 months of lost rent after a covered loss. If renovation takes 14 months after a fire, you're eating those last two months.

Umbrella Insurance

If you own multiple properties, an umbrella policy is essentially mandatory. For $200 to $400 per year, you get $1 million in additional liability coverage. One slip-and-fall lawsuit on a property with an icy sidewalk can generate a judgment that exceeds your standard policy limits before the judge finishes their coffee.

Property Taxes: The Number That Only Goes Up

Property taxes are technically not "hidden" — you know they exist. What surprises people is how much they increase over time and how dramatically they can swing after a purchase.

Many jurisdictions reassess property value at sale. If the previous owner bought the property in 2005 for $120,000 and you paid $275,000, your tax assessment might jump 50% or more in the first year. I've seen landlords lose their entire cash flow margin to a single reassessment.

Budget 1% to 2% of property value annually for taxes, and check your local jurisdiction's reassessment schedule before you buy. Some states cap annual increases (California's Prop 13, for instance), while others have no cap at all.

Legal and Professional Fees

Evictions

Nobody wants to evict a tenant. But statistically, if you own rental property long enough, you will. The average eviction costs $3,500 to $10,000 when you add up:

• Attorney fees: $500–$5,000
• Court filing fees: $50–$400
• Lost rent during the process (often 2–4 months): $3,000–$6,000
• Property damage left behind: varies widely

In some jurisdictions, the eviction process takes 3 to 6 months. In New York City, it can stretch past a year. That's a year of zero rent while you pay the mortgage, taxes, insurance, and utilities.

Accounting and Tax Preparation

Rental property tax returns are more complex than standard W-2 filings. Expect to pay $300 to $800 per year for a CPA who understands rental real estate, depreciation schedules, and the Section 199A deduction. Worth every dollar — a good CPA will save you far more than they cost.

Software and Technology

Between property management software, tenant screening services, listing syndication, and accounting tools, most landlords spend $30–$150/month on technology. PropsManager's pricing plans consolidate many of these into a single platform, which typically saves landlords $50–$100/month compared to cobbling together separate tools.

HOA Fees and Special Assessments

If your rental is a condo or in a planned community, HOA fees are a given. But special assessments are the gut punch nobody expects. The HOA decides the parking garage needs $2 million in structural repairs? That's a $15,000 special assessment per unit, due in 90 days.

I know a landlord who bought a condo specifically for rental income, ran the numbers beautifully, and then got hit with a $22,000 special assessment for a new roof and elevator modernization in year two. His entire cash-on-cash return disappeared for three years.

Before buying in an HOA community, review the reserve study and meeting minutes. Underfunded reserves are a ticking time bomb.

Utilities During Vacancy

Even when tenants pay their own utilities, you're on the hook during vacant periods. And you can't just shut everything off.

• Electric: Keep it on for showings, security systems, and to prevent mold in humid climates. Budget $50–$100/month.
• Water: Keep it on to prevent pipe freezing and for cleaning. $30–$60/month.
• Gas/Heat: In cold climates, you must maintain minimum heat (usually 55°F) to prevent frozen pipes. $75–$200/month in winter.
• Trash/Sewer: Often billed regardless. $30–$60/month.
• Internet: If your listing mentions "smart home" features or you use remote monitoring, you may need to keep internet running. $50–$80/month.

A two-month vacancy in winter can easily cost $400–$600 in utilities alone, on top of the lost rent.

The Time Cost: Your Most Hidden Expense

Here's one that never shows up on a spreadsheet but hits harder than any invoice: your time.

Managing a rental property takes work. Fielding tenant calls. Coordinating repairs. Screening applicants. Chasing late rent. Showing the unit. Filing paperwork. Driving to the property to check on things.

If you value your time at $50/hour and spend 10 hours a month managing a single property, that's $500 in opportunity cost. On a property that nets $300/month after all expenses, you're effectively paying to be a landlord.

This is exactly why property management software exists. Tools like PropsManager automate rent collection, maintenance tracking, tenant screening, and lease management — slashing the hours you spend on repetitive tasks. See how it works or request a demo to see the difference firsthand.

How to Still Make Money as a Landlord

Look, I'm not trying to scare you away from rental investing. I still own rental property and I still believe it's one of the best paths to long-term wealth. But you have to go in with realistic numbers.

Run Your Numbers Conservatively

When analyzing a deal, use the 50% rule as a quick gut check: assume 50% of gross rent goes to expenses (not including debt service). If the remaining 50% covers your mortgage and still leaves profit, the deal might work. Then dig deeper into the actual numbers.

Build Reserves Before You Buy

Have at least 6 months of expenses (mortgage, taxes, insurance, utilities) in reserve before you close. This gives you a cushion for early surprises — and there will be surprises.

Use Technology to Cut Costs

Manual property management is expensive, inefficient, and error-prone. Automating rent collection, maintenance workflows, and tenant communication through a platform like PropsManager doesn't just save time — it reduces late payments, catches maintenance issues early (before they become CapEx emergencies), and keeps tenants happier so they stay longer.

Screen Tenants Ruthlessly

The single biggest factor in your annual expenses? Tenant quality. A bad tenant who pays late, damages the property, and requires eviction can cost you $10,000–$20,000 in a single year. Thorough screening — credit checks, income verification, landlord references, background checks — costs $30–$50 per applicant and saves you thousands. Read our guide on setting the right rent price to attract quality applicants from the start.

Frequently Asked Questions

What percentage of rental income goes to expenses?

For most landlords, operating expenses consume 35% to 50% of gross rental income — and that's before mortgage payments. Older properties, those in high-tax areas, or units with included utilities can push that to 60% or higher. The safest approach is to itemize every cost category listed in this guide and build a property-specific budget rather than relying on rules of thumb alone.

How much should I set aside for maintenance and repairs each month?

The standard guideline is 1% of the property's value per year for routine maintenance, plus an additional 5%–10% of monthly rent for capital expenditure reserves. On a $200,000 property renting for $1,500/month, that works out to roughly $167/month for maintenance and $75–$150/month for CapEx — a combined $242–$317 before anything actually breaks. It feels like a lot, but one emergency boiler replacement will make you grateful you planned ahead.

What's the most underestimated hidden cost for new landlords?

Turnover. Hands down. New landlords almost never budget for the combined impact of lost rent during vacancy, make-ready costs, and marketing expenses when a tenant leaves. A single turnover on a modest apartment can easily hit $3,000–$5,000. Over a five-year period with average tenant tenure of 27 months, that's two turnovers — potentially $6,000–$10,000 you didn't see coming.

Should I manage my rental property myself or hire a property manager?

It depends on your portfolio size, proximity to the property, and how you value your time. Self-management saves the typical 8%–10% management fee but costs you hours of work every month. For one or two nearby properties, self-management with good property management software is usually the best value. Beyond 5–10 units, or for properties far from where you live, professional management often pays for itself through better tenant retention and faster maintenance response. See our deeper comparison in the role of a property manager vs. self-management.

Can I deduct all these hidden costs on my taxes?

Most operating expenses on rental property are tax-deductible, including maintenance, repairs, insurance, property management fees, software subscriptions, travel to the property, and professional fees. Capital expenditures are handled differently — they're depreciated over time rather than deducted in the year incurred. Work with a CPA who specializes in real estate to maximize your deductions and ensure compliance. The tax savings can offset a meaningful chunk of these hidden costs.

Knowing where your money goes is half the battle. The other half is building systems to track, manage, and minimize these costs before they drain your profits.

PropsManager gives landlords a single dashboard to monitor expenses, automate rent collection, manage maintenance requests, track vacancies, and generate financial reports that make tax time painless.
