Analyze rental property investment potential

Description

The Real Estate Calculator is a comprehensive tool for rental property investors. By inputting the purchase details, financing terms, and expected income/expenses, you can generate the most important “return on investment” metrics needed to decide if a property is a smart buy.

Inputs

  • Purchase Price: The total cost of the property ($).
  • Down Payment: The cash you are putting down at purchase ($).
  • Closing Costs / Rehab: All other initial cash outlays, including legal fees and repairs ($).
  • Loan Interest Rate: The annual interest rate on the mortgage (%).
  • Monthly Rent Income: The expected gross monthly rent from all units ($).
  • Monthly Expenses: The total of all non-mortgage monthly costs, including taxes, insurance, HOA fees, maintenance reserves, and vacancy allowance ($).

Outputs

  • Monthly Cash Flow: The actual profit remaining each month after all expenses and the mortgage are paid ($).
  • Cash-on-Cash Return: The annual cash flow divided by the total initial cash investment (%).
  • Cap Rate: The “Capitalization Rate,” representing the property’s yield as if it were purchased in cash (%).
  • Monthly Mortgage Payment: The principal and interest portion of your loan payment.

Chart

  • N/A: This tool provides a deep numeric analysis of investment yield.

“Good to Know”

  • A “Good” Cap Rate typically ranges from 5% to 10%, depending on the market and property type.
  • Cash-on-Cash return is often higher than the Cap Rate if you use “leverage” (a mortgage) successfully.
  • Don’t forget to budget for Vacancy (usually 5-10% of rent) and Maintenance in your monthly expenses to avoid unpleasant surprises.

Examples

Example 1: Standard Single Family Rental

  • Input:
    • Price: $300k, Down: $60k, Rehab: $9k
    • Rate: 6.5%
    • Rent: $2,500, Expenses: $1,000
  • Output:
    • Cash Flow: ~$0 (Break even after mortgage)
    • Cap Rate: 6.0%

Example 2: High Yield “Fixer”

  • Input:
    • Price: $150k, Down: $30k, Rehab: $20k
    • Rent: $1,800, Expenses: $600
  • Output:
    • Demonstrates how lower purchase prices relative to rent can lead to high Cash-on-Cash returns.

Example 3: Negative Cash Flow Warning

  • Input:
    • High Price, Low Rent, or High Interest Rate.
  • Output:
    • Alerts you if the property will cost you money out-of-pocket every month.
