Is bigger better in the world of real estate - the answer is like most things yes and no, and your personal answer will depend entirely on what you as the buyer, seller or investor are looking to achieve short and long-term.
There are many different types of real estate company and to be the BIGGEST in all categories is virtually impossible to do. There are large agencies, big funding companies and very large brokerages that while all in the real estate market place they all do things that are different and offer specialist types of services.
One way to be the biggest is simply to employ the most number of people and if you can be exact about the employee count that makes it very easy to be able to boast about being the biggest. But being the best and the biggest is another issue, one that will cause much more concern by all those involved who even worry about titles and the importance of winning property awards and competitions.
