Why a seller cares

IRR is the return an investor projects across the whole hold, timing included, and it is what a syndicate is chasing when it prices your building. A sponsor targeting a 15% IRR has a maximum price, and it is in their model.

A simple example

A buyer models your building: $250,000 down, $18,000 a year of cash flow, and a sale in year five. Their spreadsheet says 14% IRR at your price and 16% at $40,000 less.

IRR is the whole deal in one percentage, and the price you are offered is the one that hits it.

What people get wrong

That IRR is the yearly cash return. It folds in the sale and the timing, which is why it can look high on a building that pays little each year.
