What Is Rental Income?
In plain English
Rental income is the revenue received from tenants in exchange for the right to use real property. For real estate investors, it's the primary source of cash flow from income-producing properties. Rental income is taxable but can be offset by deductible expenses including mortgage interest, property taxes, insurance, repairs, and depreciation — making real estate a tax-advantaged investment vehicle.
How Do You Calculate Rental Income Potential?
Start with gross rental income — the total rent collected annually if the property is always occupied. Subtract a vacancy allowance (typically 5% to 10%) to get effective gross income. Then subtract operating expenses: property taxes, insurance, maintenance, property management fees, and any HOA dues. The result is net operating income (NOI), which drives property valuation and cash-on-cash return calculations.
What Tax Advantages Come With Rental Income?
Rental income is reduced by deductible expenses before being taxed. Depreciation — a non-cash deduction based on the IRS's 27.5-year schedule for residential property — can shelter significant income from taxes. Qualified real estate professionals can deduct rental losses against ordinary income. For others, up to $25,000 in losses may offset other income if adjusted gross income is below $100,000.
What Are the Risks of Depending on Rental Income?
Vacancies, non-paying tenants, and unexpected repairs can disrupt income. Eviction processes are time-consuming and costly. Markets shift — what rents for $2,000 today may not command the same rent in five years. Over-leveraged investors can face cash shortfalls if rental income dips. Maintaining cash reserves equivalent to three to six months of expenses per property is essential risk management.
Frequently asked questions
How does rental income affect qualifying for a mortgage?
Lenders typically allow 75% of documented rental income to count toward qualifying income, accounting for vacancy. For new rental properties, some lenders use projected market rents from the appraisal. Including rental income can significantly increase how much you can borrow.
Is rental income from a short-term rental taxed differently?
Short-term rental income (properties rented less than 14 days) may be excluded from taxable income entirely under the 'Augusta Rule.' Above 14 days, income is taxable. Deductions are also prorated based on personal vs. rental use days. State and local rental taxes may apply separately.
