What is market cap in real estate?

Generally speaking, market cap, or market capitalization, refers to how much of the specific market a publicly traded company has control over. In real estate, this refers to how much a company in control of properties has control of the broader property and real estate market. For example, CBRE has a market cap of $49.6 billion. This means that if you were to add up the total amount of money in the real estate market, CBRE would control or influence around $50 billion of it.

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

There is no one single perfect answer to this question. It will depend on how much risk investors are willing to take, as the larger the market cap, the greater the chances of both making and losing money. However, most experts agree that anywhere between 8% and 18% is likely a good place to start in your research.
