Monthly Expenses Every Rental Property Owner Should Budget For

Here's a mistake that costs landlords real money: they look at rent as revenue and the mortgage payment as the only expense. Everything in between — vacancy, management, maintenance, reserves — gets forgotten until it bites them.

A property renting for $1,500/month with an $1,100 mortgage payment is not generating $400/month in profit. Our first rental property guide covers how to build an accurate expense model before you make an offer. It might be generating $0. It might be negative. Here's the actual math.

Fixed Monthly Expenses

These don't change month to month, which makes them easy to account for — and yet people still miss them:

• Mortgage (principal and interest): The number your lender gives you. Easy.
• Property taxes: Divide your annual bill by 12 and treat it as a monthly cost. On a $200,000 property in a typical market, this might be $200–$400/month.
• Insurance: Landlord insurance (not homeowner's — different policy) runs higher than owner-occupied rates. Budget $100–$200/month on a single-family rental.
• HOA fees: If applicable. These vary wildly and can significantly affect cash flow, especially in condo associations.

Variable Operating Expenses

These fluctuate but need to be budgeted as if they're monthly costs, because on average they are:

• Property management (8–12% of gross rent + leasing fee): If you hire a manager, expect 10% of collected rent plus one month's rent as a leasing fee every time you turn the unit. On $1,500/month rent, that's $150/month ongoing, and $1,500 every time you place a new tenant. That leasing fee often gets forgotten in pro formas.
• Maintenance (5–10% of gross rent): Budget $75–$150/month on a $1,500 rental. Some months are zero. Some months the HVAC fails and it's $3,000. This average holds over time.
• Vacancy (5–8%): Even good landlords with good tenants experience turnover. Budget one month empty per year at minimum — that's 8.3% of annual rent. On a $1,500 property, that's $1,500 per year, or $125/month amortized.

CapEx Reserves — The Most Ignored Category

Capital expenditures are the big-ticket replacements that aren't maintenance — they're one-time costs that happen every 10–25 years. Most landlords save nothing for these, then get surprised when a $6,000 HVAC replacement shows up.

The major items to reserve for:

• HVAC system: $4,000–$8,000 to replace
• Roof: $8,000–$20,000 depending on size and materials
• Water heater: $800–$2,000
• Flooring replacement: $3,000–$8,000 for a full house
• Windows, appliances, plumbing, electrical — all eventually need attention

A reasonable CapEx reserve is 5–10% of gross monthly rent, kept separate from your maintenance budget. It's not money you spend — it's money you accumulate so that when the roof needs replacing in year 14, you're not scrambling.

The Full Picture on a $1,500/Month Rental

Let's run the actual numbers on a $1,500/month rental with a $1,100 mortgage payment:

• Mortgage (P&I): $1,100
• Property taxes: $250
• Insurance: $100
• Management (10%): $150
• Maintenance reserve (7%): $105
• Vacancy reserve (7%): $105
• CapEx reserve (7%): $105

Total expenses: $1,915. Monthly rent: $1,500. That property is losing $415/month before you've fixed a single thing.

This is the 50% rule in action. Operating expenses excluding debt service typically run 40–60% of gross rent. On $1,500/month, that's $600–$900 in non-mortgage expenses. If your mortgage is above $600–$900, you almost certainly don't cash flow. Many landlords own properties that match this description exactly and wonder why the investment isn't "working."

Tax Deductions That Offset the Costs

Rental property ownership does have real tax advantages — they just don't change the cash flow math above. What you can deduct against rental income:

• Mortgage interest (not the full payment — just the interest portion)
• Property taxes
• Depreciation — the IRS lets you deduct 1/27.5th of the property value annually, which is a non-cash deduction that can offset income
• Management fees, maintenance and repairs, insurance, advertising, professional fees

Depreciation is real money. On a $200,000 property value (excluding land), that's $7,272/year in paper deductions that reduce your taxable income. But it doesn't put cash in your account. Understand what these deductions do and don't do before you build a business case around them.

Self-Managing vs. Hiring a Property Manager

Keeping the 10% management fee in your pocket is real — on a $1,500 rental, that's $1,800/year. But self-managing costs you something too: time, knowledge of landlord-tenant law in your state, the stress of late-night maintenance calls, and the expertise to handle evictions without making expensive legal mistakes.

For more on what professional management entails, see our breakdown of property management companies. For one property in your backyard: self-managing is reasonable if you're willing to learn the legal requirements. For multiple properties, properties out of state, or if you have a day job you're not willing to compromise — the management fee is almost certainly worth it. The math changes when one poorly-handled eviction costs you $3,000 in legal fees and two months of vacancy.
