Want to know if a rental will actually make money before you sign the contract? In the next few minutes you’ll learn **exactly how to run a rental property cash flow analysis** and see a free worksheet that does the math for you. Skip the guesswork, avoid costly surprises, and decide with confidence whether a property is worth buying.

## The hidden cost of guessing cash flow

The first time I bought a duplex I trusted gut instinct: “If rent covers the mortgage, I’m good.” That shortcut ignored **property taxes, insurance, maintenance, vacancy periods, and unexpected repairs**—the line items that turn a rosy projection into a monthly loss. After a few months of negative cash flow, I realized I needed a systematic **rental property cash flow analysis** that listed every cash‑in and cash‑out.

## Step‑by‑Step Rental Property Cash Flow Analysis

1. **Gather income** – Record the expected monthly rent. Add any extra streams such as laundry fees, parking, or pet rent.  
2. **List fixed expenses** – Mortgage principal & interest, property tax, insurance, and HOA fees. These figures are easy to pull from your loan and tax statements.  
3. **Add variable expenses** –  
   * Utilities you’ll cover  
   * Property‑management fees (usually 5 % of rent)  
   * Marketing costs for new tenants  
   * A maintenance reserve (≈ 1 % of the property’s value per month)  
4. **Account for vacancy** – Assume a 5 % vacancy rate: multiply monthly rent by 5 % and treat that amount as an expense.  
5. **Calculate cash flow** – Subtract total expenses from total income. A positive result means the property covers its costs; a negative result signals you need to cut costs or raise rent.  
6. **Project annually** – Multiply the monthly cash flow by 12 to see the yearly picture and compare it with other investment options.

## Common pitfalls and how to avoid them

- **Skipping preventive maintenance** – Delaying HVAC service or roof repairs creates larger, unexpected bills later.  
- **Under‑budgeting vacancy** – Assuming 100 % occupancy is unrealistic; the 5 % rule protects you from cash‑flow gaps.  
- **Relying on rent hikes alone** – Raising rent without addressing high expenses rarely solves a negative cash flow problem.

## Quick scenario testing

Once you have a baseline, experiment:  
- **Raise rent by $50** – Does the cash flow turn positive?  
- **Refinance to a lower rate** – How much does the monthly mortgage payment drop?  
- **Reduce maintenance reserve** – Is a 0.8 % reserve realistic for this property?

These “what‑if” calculations help you decide whether to move forward, negotiate a lower purchase price, or walk away.
