Internal Rate of Return (IRR) in Real Estate: A Plain-Language Guide

What Is Internal Rate of Return (IRR)?

Internal rate of return (IRR) is the single annualized rate that makes the present value of all a project cash flows equal to zero. In plain terms, it is the yearly return a deal earns once you account for both how much cash comes in and when it arrives.

IRR is powerful because it captures the full life of an investment: the initial cash invested, annual cash flow, and the lump sum from a sale or refinance. A dollar received next year is worth more than the same dollar in year ten, and IRR builds that time value directly into the number.

How IRR Works

IRR is the discount rate that sets the sum of all discounted cash flows, including the negative upfront investment, to zero. Because it appears inside an exponent for every period, there is no simple algebraic formula; it is solved by iteration in a spreadsheet or calculator.

The inputs are a timeline of cash flows: a negative number in year zero for cash invested, positive annual cash flow during the hold, and a large positive figure in the final year for net sale proceeds.

IRR vs Cash-on-Cash Return

• Cash-on-cash return measures one year of cash flow against cash invested; it ignores timing and the eventual sale.
• IRR blends every year of cash flow plus sale proceeds into one annualized figure.
• A property can have a modest cash-on-cash return but a strong IRR if appreciation and loan paydown produce a large sale gain.
• IRR rewards getting cash back sooner, so a mid-hold cash-out refinance can lift IRR.
• Use cash-on-cash for a quick yearly snapshot and IRR to compare full-hold performance across deals.

Worked Example

An investor puts in $100,000, collects $8,000 of cash flow per year for five years, and sells at the end of year five for $150,000 net of the loan payoff and selling costs.

The cash flows are -$100,000 in year zero, +$8,000 in years one through four, and +$158,000 in year five. Solving for the rate that discounts these to zero gives an IRR of roughly 17%, well above the 8% cash-on-cash return, because the sale gain is included.

Where IRR Falls Short

IRR assumes interim cash flows are reinvested at the same IRR, which can overstate returns for very high-IRR deals. It also collapses a complex hold into one number, hiding whether the return came from cash flow or a single optimistic sale assumption.

Because the sale price drives so much of the result, always stress test the exit. A conservative appreciation estimate, which you can model in an appreciation calculator, keeps the IRR honest.
