Understanding Rental Property Income

Investing in rental properties can be a significant source of passive income, but it's crucial to accurately estimate profitability. This calculator simplifies the process by taking into account both potential income and a comprehensive list of common expenses associated with owning a rental property.

Key Factors Explained:

  • Estimated Monthly Rent: This is the gross income you expect to receive from your tenant each month.
  • Vacancy Rate: Properties are rarely occupied 100% of the time. This percentage accounts for periods when the property is vacant between tenants, reducing your overall rental income. It's often expressed annually and then converted to a monthly deduction.
  • Property Taxes: These are annual taxes levied by local governments on real estate.
  • Property Insurance: Essential coverage to protect against damage, liability, and loss of rental income.
  • Maintenance & Repairs: An ongoing cost for upkeep, from minor fixes to major replacements. It's often estimated as a percentage of the annual rent.
  • Property Management Fees: If you hire a property manager, their fees (usually a percentage of collected rent) are a significant expense.
  • HOA Dues: If the property is part of a Homeowners Association, these monthly fees cover shared amenities and maintenance.
  • Other Annual Expenses: This category can include things like utilities (if paid by the owner), legal fees, accounting costs, or specific repairs.

By subtracting all these expenses from your gross rental income, you arrive at your Net Monthly Income. This metric is vital for assessing the financial viability of a rental property and comparing different investment opportunities.
