Paying rent to my real estate LLC

[Bharath Raj]

I would like to move my medical practice business (LLC) into a suite of a commercial building (different LLC). I will lease the remainng space to a separate tenant. Can my business LLC pay by real estate LLC rent at market rate? Are there any special rules? Paying myself a rent should help me realize some depreciation and decrease my tax bill, since my commercial building on it's own is not generating any income currently.
