What is market cap in real estate?

Market cap is the total value of a company's stock, and it's a term used with companies across market sectors, including real estate. Real estate companies also use capitalization rates, or cap rates, to measure the risk and return of commercial properties. To calculate the cap rate, divide a property's annual net operating income by its market value.

In today's real estate market, what cap rate are investors looking for?

Investors generally look for a cap rate between 5% and 10% in today's real estate market, but it depends on the investor's risk tolerance, the market, and the type of property.
