Frequently Asked Questions

What is cash-on-cash return?

Cash-on-cash return measures your annual pre-tax cash flow divided by the total cash you invested (down payment + closing costs). A 10% cash-on-cash return means you earn 10 cents per year for every dollar you put in. Most investors target 8-12%.

What is cap rate?

Capitalization rate (cap rate) is the net operating income divided by the purchase price, ignoring financing. It tells you what return the property generates on its own, regardless of how you finance it. A higher cap rate means higher return but often higher risk.

What is the 1% rule?

The 1% rule is a quick screening test: monthly rent should be at least 1% of the purchase price. A $200,000 property should rent for at least $2,000/month. Properties that pass the 1% rule are more likely to produce positive cash flow.

What expenses should I include?

Include mortgage payment, property taxes, insurance, HOA fees, property management (8-12% of rent), maintenance reserves ($100-200/month), and vacancy allowance (5-8% of rent). Underestimating expenses is the most common mistake new investors make.
