What Is Rental Income?
Gross rental income is every dollar collected from tenants—base rent, pet fees, parking charges, laundry revenue. Net rental income subtracts vacancy, operating expenses (taxes, insurance, repairs, management), and reserves. The IRS taxes rental income on Schedule E (Form 1040), where you report gross rents and deduct expenses including depreciation. Most rental income is classified as passive income, which means losses can typically only offset other passive income—unless you qualify for the $25,000 rental loss allowance. The average gross rental yield in the U.S. is approximately 6.56%, though markets like Cleveland (9.8%) and Memphis (7.2%) consistently outperform.
Rental income is the money a property owner collects from tenants in exchange for occupying a residential or commercial property. It is the foundation of buy-and-hold real estate investing.
At a Glance
- What it is: Money collected from tenants for property use
- Gross vs. net: Gross = total collected; Net = gross minus vacancy and expenses
- Tax form: IRS Schedule E (Form 1040)
- National average yield: ~6.56% gross (Q4 2025)
- Top-performing markets: Cleveland (~9.8%), Memphis (~7.2%), Indianapolis (~7.0%)
Net Rental Income = Gross Rent - Vacancy - Operating Expenses
How It Works
Gross rental income. This includes base rent plus all ancillary revenue: pet rent ($25–75/month), parking fees ($50–150/month in urban areas), laundry income, late fees, and application fees. If you collect it from tenants, it's gross rental income. For a duplex in Indianapolis renting each unit at $1,100/month, gross annual rental income is $26,400.
From gross to net. Subtract vacancy (typically 5–8% for residential), then operating expenses: property taxes, insurance, repairs and maintenance, property management fees (8–10% of collected rent), utilities you cover, and reserves for capital expenditures (5–10% of rent). Using the Indianapolis duplex: $26,400 gross - $1,584 vacancy (6%) - $9,240 operating expenses = $15,576 net rental income, or roughly $1,298/month before debt service.
Tax treatment. The IRS requires reporting all rental income on Schedule E. You deduct mortgage interest, property taxes, insurance, repairs, management fees, travel to the property, and depreciation (residential buildings depreciated over 27.5 years). Depreciation is a non-cash deduction that often creates a paper loss even when you're cash-flow positive. Most rental activity is classified as passive—losses can only offset passive income unless you actively participate and earn under $150,000 AGI, qualifying for up to $25,000 in deductions against ordinary income.
Building financial independence. Rental income is a core strategy in the FIRE (Financial Independence, Retire Early) movement. An investor with 10 paid-off rental units generating $1,000/month net each has $120,000 in annual passive income—enough to replace most W-2 salaries. The compounding effect of reinvesting rental income into additional properties accelerates this timeline.
Real-World Example
Priya in Memphis. Priya buys a 3-bedroom single-family rental in Whitehaven for $185,000. Market rent is $1,400/month ($16,800/year gross). Her expenses: property taxes $1,850, insurance $1,200, property management at 9% ($1,512), maintenance reserve $1,200, vacancy reserve at 6% ($1,008). Total operating expenses: $6,770. Net operating income: $10,030. Her mortgage payment (P&I) on a 75% LTV loan at 6.75% is $962/month ($11,544/year). Annual cash flow after debt service: -$1,514 in year one. But on her Schedule E, she deducts $5,381 in depreciation ($142,750 building value / 27.5 years) plus mortgage interest of ~$9,200—creating a paper loss that offsets other passive income. Her gross yield: 9.1%. Her equity grows each month through principal paydown, and rents typically increase 3–5% annually in this market.
Pros & Cons
- Predictable monthly income stream—tenants pay on a fixed schedule
- Tax advantages through depreciation, expense deductions, and passive loss rules
- Income grows with inflation as rents increase over time
- Can be scaled from one unit to hundreds
- Builds equity through tenant-paid mortgage paydown
- Vacancy periods produce zero income while expenses continue
- Tenants can cause damage exceeding security deposits
- Property management requires time (active) or fees (passive)
- Concentration risk—one property in one market
- Rent collection issues and potential eviction costs ($3,500–7,000 per case)
Watch Out
- Gross vs. net confusion. A property advertised as "$2,000/month rent" sounds great until you subtract $1,600 in expenses and debt service. Always underwrite to net cash flow, not gross rent.
- Passive income isn't passive work. The IRS calls it passive, but managing tenants, maintenance, and turnovers is active effort unless you hire a property manager.
- Security deposit rules. These aren't rental income—they're held in trust and must be returned minus legitimate damages. Commingling deposits with rental income is illegal in most states.
- Local rent control. Some cities cap annual rent increases at 3–5%, limiting your income growth. Check local laws before buying in Portland, Los Angeles, or New York City.

The Takeaway
Rental income is the engine of buy-and-hold real estate investing. Gross rent minus vacancy and operating expenses equals your net operating income—the number that determines whether a property works. The U.S. averages 6.56% gross yields, but top markets hit 8–10%. Schedule E lets you deduct expenses and depreciation, often creating tax losses on properties that are cash-flow positive. Start with one property, master the income and expense equation, and scale from there.
