Gross vs Net Rental Yield

Gross yield = Annual Rent ÷ Purchase Price. Quick screening metric — ignores expenses. Net yield = NOI ÷ Purchase Price. More accurate — includes vacancy, taxes, insurance, and maintenance. A property with 8% gross yield might only have 5-6% net yield after expenses. Always use net yield when comparing investment properties.

Cash Flow Analysis

Monthly cash flow = NOI/12 minus mortgage payment. Positive cash flow means the property pays for itself and generates income. Aim for $200+/month positive cash flow per unit. Negative cash flow means you are subsidizing the property — acceptable only if strong appreciation is expected. The 1% rule (monthly rent ≥ 1% of purchase price) is a quick screening tool: $300K property should rent for $3,000+/month to likely cash flow positive.

Frequently asked questions
What is a good rental yield?
Gross yield 6-10% is good for residential rentals. Net yield 4-7% after expenses. In expensive markets (NYC, SF), yields are 3-4%. In affordable markets (Midwest, South), 8-12% is achievable. The tradeoff: high-yield markets have less appreciation potential.
What is the 1% rule in real estate?
Monthly rent should be at least 1% of the purchase price. A $200,000 property should rent for $2,000+/month. This is a screening tool, not a guarantee — properties meeting the 1% rule are more likely to generate positive cash flow after expenses and mortgage.
