Enter all recurring annual expenses — property tax, insurance, HOA, maintenance, and other costs — along with their annual increase rates.
5
Enter your sell plan — either a known sell price or an annual appreciation rate — along with holding length and cost to sell. Then click Calculate.
Key Investment Metrics Explained
IRR — Internal Rate of Return
The annualized rate of growth your investment generates over the full holding period. The most comprehensive profitability metric — it accounts for the time value of money and includes both cash flow and sale proceeds.
Cap Rate — Capitalization Rate
Net Operating Income divided by purchase price. Shows your return if you paid all cash — great for quickly comparing properties. Formula: Cap Rate = NOI ÷ Purchase Price × 100.
Cash on Cash Return
Annual cash flow divided by total cash invested (down payment + closing costs + repairs). Measures how efficiently your actual cash investment generates returns — critical when using a loan.
NOI — Net Operating Income
Effective gross income minus all operating expenses — before mortgage payments. A positive and growing NOI is the foundation of a healthy rental property investment.
Quick Rules of Thumb for Investors
| Rule | What It Says | Best Used For |
|---|---|---|
| The 50% Rule | Operating expenses ≈ 50% of gross income — remaining 50% covers mortgage | Quick cash flow estimate |
| The 1% Rule | Monthly rent should be ≥ 1% of purchase price after repairs | Initial property screening |
| The 2% Rule | Monthly rent ≥ 2% of purchase price — higher cash flow target | Competitive markets |
| The 70% Rule | Max purchase price = 70% of ARV minus repair costs | House flipping only |
Frequently Asked Questions
A good IRR for rental property typically ranges from 8% to 12% per year for a stabilized residential property. Higher returns above 15% are possible with value-add strategies — buying below market, making improvements, and increasing rents. IRR below 6% often means the investment is better suited for a REIT or index fund. Always compare the IRR to your alternative investment options to assess if the rental property is worth the additional effort and risk.
A vacancy rate of 5% to 10% is a conservative and realistic estimate for most residential rental properties. This accounts for time between tenants, screening periods, and occasional extended vacancies. In strong rental markets with low supply you may experience lower vacancy — but always plan conservatively. Never use 0% vacancy in your projections as this creates an unrealistically optimistic picture of your investment.
Property management companies typically charge 8% to 12% of monthly rent plus leasing fees. They handle tenant screening, rent collection, maintenance coordination, and evictions — saving you significant time. For investors who live far from the property, own multiple units, or do not want active involvement, the fee is usually worth it. Enter the management fee percentage in the calculator to see its exact impact on your cash flow and IRR.
Historically US home values have appreciated at an average of 3% to 4% per year over long periods. Some markets — particularly major metro areas — have seen higher appreciation while rural markets may see lower. For conservative financial planning use 2% to 3% as your baseline appreciation assumption. Running the calculator with different appreciation scenarios (low 2%, base 3%, high 5%) gives you a range of possible outcomes rather than a single projection.
