Real estate investing combines cash flow, appreciation, leverage, and significant tax advantages into one asset class. But calculating true returns requires understanding depreciation, capital gains, financing costs, and rental income tax treatment — all at once. This hub gives you every calculator and guide to analyze deals and maximize after-tax returns.
Core Real Estate Financial Metrics
Net Operating Income (NOI)
NOI is the annual rental income minus operating expenses (excluding mortgage payments and taxes). It's the starting point for every property valuation.
NOI = Gross Rental Income − Vacancy − Operating Expenses
Cap Rate
The capitalization rate tells you the unlevered return of a property at its current price. Most residential rentals trade at 4–8% cap rates; commercial properties can be higher.
Cap Rate = NOI ÷ Purchase Price
Cash-on-Cash Return
This measures the actual cash yield on your invested equity — accounting for debt service.
Cash-on-Cash = Annual Pre-Tax Cash Flow ÷ Total Cash Invested
Debt Service Coverage Ratio (DSCR)
Lenders require DSCR above 1.0 to approve financing. Most require 1.20–1.25 for investment properties.
DSCR = NOI ÷ Annual Debt Service
Tax Advantages of Real Estate
Real estate is one of the most tax-advantaged asset classes available:
- Depreciation — Residential properties depreciate over 27.5 years; commercial over 39 years. This non-cash deduction can create paper losses that offset rental income.
- Mortgage interest deduction — Interest on investment property mortgages is deductible against rental income.
- 1031 Exchange — Defer capital gains indefinitely by rolling proceeds into a like-kind property within IRS deadlines.
- Section 121 Exclusion — Exclude up to $250,000 ($500,000 married) of gain on a primary residence sale.
- Opportunity Zones — Defer and reduce gains by investing in designated census tracts.
- Passive Activity Rules — Losses from rental properties may offset up to $25,000 of ordinary income for active participants earning under $100,000.
Investment Property Financing
Getting the right mortgage for an investment property is harder than financing a primary residence:
- Down payments typically 20–25%
- Rates are 0.5–0.75% higher than primary residence rates
- DTI ratio limits of 43–45% for most conventional loans
- DSCR loans qualify based on property cash flow, not personal income
