How to Use
- Enter the purchase price, down payment, and closing-cost assumptions for the property you are analyzing.
- Add expected monthly rent and recurring operating expenses such as repairs, taxes, insurance, and management.
- Set a realistic vacancy assumption so the income estimate is not too optimistic.
- Review monthly cash flow, annual NOI, cap rate, and cash-on-cash return before comparing the property with other deals.
Frequently Asked Questions
What is NOI?
NOI means net operating income. It is rental income after vacancy and operating expenses but before financing, income taxes, and depreciation.
What does cap rate tell me?
Cap rate is NOI divided by purchase price. It gives you a fast way to compare the income performance of one property against another before financing is considered.
What is cash-on-cash return?
Cash-on-cash return compares annual pre-tax cash flow with the actual cash invested upfront, which helps when comparing leveraged real-estate deals.
Should I model vacancy even in a strong market?
Yes. A vacancy assumption keeps the analysis grounded because nearly every rental property experiences some turnover, downtime, or credit loss.
Does this include a mortgage payment?
This version focuses on property operating performance and the cash invested. If you also want loan payment detail, pair it with the mortgage calculator.
