What Are Cash Flowing Properties? How to Find & Analyze Them
Cash flowing properties generate more rental income than they cost to own. Learn how to identify, analyze, and acquire properties that put money in your pocket every month.
What Is Cash Flow in Real Estate?
Cash flow is the money left over after you collect rent and pay all property-related expenses. It's the simplest measure of whether a rental property is making or losing money each month.
Simple Definition:
A cash flowing property (also called a “cash flow positive” property) generates more income than expenses, leaving you with profit each month. This is the foundation of building passive income through real estate.
Why Cash Flow Matters: Properties that cash flow let you hold them indefinitely. You're not depleting savings to cover costs—the property pays for itself and puts extra money in your pocket.
How to Calculate Cash Flow
Cash flow is calculated by subtracting all expenses from your gross rental income. Here's what to include:
Income
- Monthly rent
- Pet rent/fees
- Parking fees
- Laundry income
- Late fees (occasional)
Expenses
- •Mortgage payment (P&I)
- •Property taxes
- •Insurance
- •Property management (8-10%)
- •Vacancy (5-8%)
- •Repairs/maintenance (5-10%)
- •CapEx reserves (5-10%)
- •HOA fees (if applicable)
- •Utilities (if landlord-paid)
Example Cash Flow Calculation
Property: 3-bed single-family home, $200,000 purchase price, 25% down payment
Loan: $150,000 at 7% interest, 30-year fixed
| Monthly Rent | +$1,800 |
| Mortgage (P&I) | -$998 |
| Property Taxes | -$200 |
| Insurance | -$100 |
| Property Management (8%) | -$144 |
| Vacancy Reserve (5%) | -$90 |
| Maintenance Reserve (5%) | -$90 |
| CapEx Reserve (5%) | -$90 |
| Monthly Cash Flow | +$88 |
This property generates $88/month ($1,056/year) in positive cash flow. With $50,000 invested (down payment + closing costs), that's approximately a 2.1% cash-on-cash return before accounting for appreciation and loan paydown.
Positive vs Negative Cash Flow
Positive Cash Flow
Property generates more income than expenses. Money goes into your pocket each month.
Negative Cash Flow
Expenses exceed income. You must contribute money each month to cover costs.
When Negative Cash Flow Might Be OK: Some investors accept slight negative cash flow in high-appreciation markets like Austin or Phoenix, betting on significant value increases. This is riskier but can work if you have strong reserves and a long time horizon.
How to Find Cash Flowing Properties
Finding properties that cash flow requires knowing where to look and how to quickly screen deals. Here's the process:
Target Cash Flow Markets
Not all markets support cash flow. Focus on areas where property prices are low relative to rents—typically Midwest and Southeast markets.
Use Quick Screening Rules
Before running full analysis, use rules of thumb to quickly filter deals:
- 1% Rule: Monthly rent should equal 1% of purchase price
- 50% Rule: Half of rent goes to expenses (excluding mortgage)
- Price-to-Rent: Price divided by annual rent under 15 is favorable
Run Full Analysis on Promising Deals
For properties that pass initial screening, run complete cash flow analysis including all expenses, realistic vacancy, and maintenance reserves.

Best Markets for Cash Flow
These markets consistently offer the best cash flow potential due to favorable price-to-rent ratios and landlord-friendly regulations:
| Market | Median Price | Avg Rent | 1% Rule | Cash-on-Cash |
|---|---|---|---|---|
| Cleveland, OH | $125,000 | $1,200 | 0.96% | 10-14% |

| Detroit, MI | $100,000 | $1,100 | 1.10% | 12-18% |
Common Mistakes That Kill Cash Flow
Underestimating Expenses
New investors often forget vacancy, maintenance, CapEx reserves, or property management. Always account for 25-35% of rent going to operating expenses beyond the mortgage.
Overestimating Rent
Optimistic rent projections destroy cash flow. Research actual comparable rentals, not asking prices. Factor in your property's specific condition and features.
Buying in the Wrong Market
A $500,000 property renting for $2,500 in a coastal market will never cash flow. Location determines cash flow potential more than any other factor.
Ignoring Hidden Costs
HOA fees, special assessments, high property taxes, flood insurance—these can eat hundreds per month. Research all costs before making an offer.
Using Low Down Payment
Lower down payments mean higher mortgage payments and PMI. A 20-25% down payment is typically needed for positive cash flow. Going lower requires exceptional deals.
Rules of Thumb for Quick Analysis
Use these rules to quickly filter properties before running full analysis:
1% Rule
Monthly rent should be at least 1% of the purchase price.
Example: $200,000 property should rent for $2,000/month minimum.
50% Rule
Assume 50% of rent goes to operating expenses (not including mortgage).
Example: $1,800 rent = $900 for expenses, $900 available for mortgage + cash flow.
70% Rule (Flips)
For fix-and-flip: Offer no more than 70% of ARV minus repairs.
Example: $300K ARV - $50K repairs = $160K max offer.
GRM Rule
Gross Rent Multiplier under 10 is excellent, under 15 is acceptable.
Formula: Price ÷ Annual Rent. $200K ÷ $21,600 = 9.3 GRM ✓
