Key Metrics Explained

Cash Flow

Monthly income minus all expenses. Positive cash flow means the property generates profit.

Cap Rate

Annual net operating income divided by property value. Higher cap rates indicate better returns.

Cash-on-Cash Return

Annual cash flow divided by total cash invested. Measures return on your actual investment.

1% Rule

Monthly rent should be at least 1% of purchase price. A quick screening tool for cash flow potential.

50% Rule

Operating expenses typically consume about 50% of rental income. Useful for quick estimates.

Investment Strategies

Cash Flow Investing

Focus on properties that generate positive monthly cash flow from day one.

Appreciation Investing

Buy in areas with strong growth potential, accepting lower initial cash flow for future gains.

BRRRR Strategy

Buy, Rehab, Rent, Refinance, Repeat. Use refinancing to pull out capital for the next investment.

House Hacking

Live in one unit of a multi-family property while renting out the others to cover expenses.

Example Calculation

Property: $300,000 single-family home

• Purchase Price: $300,000

• Down Payment (20%): $60,000

• Monthly Rent: $2,500

• Monthly Expenses: $1,200

• Monthly Mortgage: $1,580

• Monthly Cash Flow: -$280

• Cap Rate: 5.2%

• Cash-on-Cash Return: -5.0%

This property would have negative cash flow but might work in an appreciating market.

Frequently Asked Questions

What's a good cap rate for rental properties?

Generally 4-10% depending on location and property type. Higher cap rates often mean higher risk areas.

Should I buy a property with negative cash flow?

Only if you expect significant appreciation and can afford the monthly shortfall. Cash flow properties are generally safer.

How much should I budget for maintenance?

Typically 5-10% of rental income, or $1-2 per square foot annually. Older properties require more maintenance.
