Federal Tax Schedule E: Separate into units or use whole park?

I purchased my first park and multi-unit property last November. For some of the veterans, I was wondering how you handled Schedule E on your federal tax return? Do you list each lot individually or do you put just the whole park on your Schedule E? If you do the whole park on Schedule E, then do you provide supporting documentation for the individual lots/units for things like repairs, which might be a very large amount for a whole park? Large items in Schedule E without supporting documentation seem like they might be a red flag with the IRS. Thanks in advance, Mike
