Understanding the Costs of Owning Rental Properties

So, you’re thinking about owning rental properties—or maybe you already do. Either way, you probably already know that rental income can be a great way to build wealth, generate cash flow, and increase your net worth over time. But here’s the catch: too many investors underestimate the real costs that come with owning rental properties.

This isn't just about your mortgage. From maintenance to vacancy, every little cost chips away at your returns if you're not prepared. The better you understand what to expect, the easier it is to make smart investment decisions that actually make you money.

Know Your Mortgage—But Don’t Stop There

Most people start with the mortgage, which is a good first step. If you’ve financed the property, your mortgage payment typically includes principal, interest, property taxes, and homeowners insurance. Depending on where you buy and how much you put down, this monthly cost will probably be your biggest single expense.

But here’s where many investors stop. They run the numbers, see that rent will cover the mortgage, and assume they’ll be cash flow positive.

That’s like budgeting for a road trip and only accounting for gas—not tolls, food, or flat tires.

Repairs and Maintenance Are Inevitable

Even if the property is in great condition when you buy it, stuff breaks. Appliances wear out. Tenants accidentally cause damage. Nature happens.

A good rule of thumb:

Set aside 1% of the property’s value annually for repairs and maintenance.

So, if your rental is worth $250,000, keep $2,500 a year earmarked for repairs. Some years you might only need to replace a microwave. Other years, it’s a furnace or a new roof. Planning ahead keeps you from scrambling.

Vacancy Happens—Plan for It

Even with great tenants, you’re going to deal with turnover eventually. And every time a unit sits empty, that’s lost income.

A good rule of thumb is to factor in 5% to 10% vacancy per year. That might be just a couple of weeks, or it could be a full month depending on your market and how efficiently you can turn over the unit.

For example, if your rent is $2,000 a month, losing one month per year means you’re effectively bringing in $22,000 annually—not $24,000. That’s a big difference if you weren’t expecting it.

Property Management: Worth Every Penny

Managing a property yourself can save money, but it’s also a lot of work—especially if you have a full-time job or live far from the property. That’s where property management companies come in.

Most charge around 8% to 12% of your monthly rent, plus a leasing fee when filling vacancies. On a $2,000 rental, that could mean $160–$240 a month, plus half a month’s rent every time they have to find a new tenant.

Is it worth it? For many investors, absolutely. But whether you go DIY or hire out, you still need to account for the cost of your time or the manager’s fee in your overall numbers.

Capital Expenditures: The Big Stuff

While maintenance handles small, ongoing repairs, capital expenditures—or CapEx—cover the big-ticket items. These are things like roofs, HVAC systems, appliances, and water heaters. They don’t break every year, but when they do, they can be expensive.

To avoid being blindsided, it’s wise to save for CapEx just like you do for maintenance. Some investors set aside $100–$200 a month depending on the age and condition of the property.

Here’s a simple example: let’s say your water heater is 10 years old, and a new one costs $1,500 installed. If you start setting aside $25 a month now, you’ll be ready when it goes out in a few years—no stress, no scrambling.

Utilities and Landscaping: Who Covers What?

Depending on the property and the lease agreement, you may be responsible for certain utilities or exterior services. In a single-family home, tenants often cover all utilities. In a duplex or triplex, you might still be on the hook for water, sewer, trash, or common area electricity.

And don’t forget the yard. If your lease doesn’t make landscaping the tenant’s responsibility, that’s on you. Even basic lawn care can run $50–$100 a month depending on the property.

HOA Fees: The Hidden Cost

If your property is in a neighborhood with a homeowners association (HOA), those monthly fees need to be baked into your calculations. Some HOAs are just $50–$100 per month, but others—especially those with amenities—can be $300 or more.

What’s more, HOAs sometimes hit owners with special assessments for repairs or improvements. These aren’t always predictable, so having a buffer in your budget helps protect your cash flow.

Insurance and Liability Coverage

You’ll need more than just homeowners insurance. Landlord insurance policies are designed specifically for rentals and offer added protections—like coverage for loss of rent if your unit becomes uninhabitable.

These policies generally cost a little more, but they’re worth every penny. Expect to pay $800–$1,200 annually for comprehensive landlord coverage, depending on location and property type.

Taxes: It’s Not Just Property Taxes

Yes, property taxes are part of your mortgage payment—but don’t forget income taxes. Rental income is taxable, but the upside is that real estate comes with a ton of write-offs.

You can deduct things like:

• Mortgage interest
• Depreciation
• Repairs and maintenance
• Property management fees

That said, tax strategy can get a bit complex. It’s a smart move to work with an accountant who specializes in real estate. They’ll help you stay compliant and maximize your deductions.

Depreciation and Tax Benefits (The Silver Lining)

Here’s the good news: many of the costs of owning rental properties can be offset by tax deductions. Mortgage interest, property taxes, insurance, repairs, and depreciation can all reduce your taxable rental income.

Depreciation is a major benefit—you can deduct a portion of the property’s value each year over a 27.5-year schedule. That means even if you’re cash-flowing, your taxes could show a loss (a win for your wallet).

Just make sure you’re working with a CPA who understands real estate to help you take full advantage.

Conclusion: Know Before You Grow

Owning rental properties can absolutely be profitable, but only if you account for all the costs—not just the obvious ones. Smart investors run the numbers conservatively, build in buffers, and treat their properties like a business.

So whether you’re buying your first duplex or scaling up to a portfolio of multi-family homes, having a solid handle on these expenses sets you up for long-term success.
