How to determine value of a real estate business?

[Tom Sylvester]

I'm a 50/50 owner in an LLC that holds a variety of real estate. We are looking to either buy our partner out or have our partner buy us out. In order to do this, we'd first like to figure out the true value of the business.

Does anyone have any useful guidance/articles/companies that can help us assess the value of the business?

Has anyone else gone through this process before?  Any tips or guidance would be greatly appreciated.

Thanks in advance!
