I'd read through all the laws pertaining to your operation.

,Is this LLC operating as an S-corp or as a sole proprietor?

Are you referring to start-up costs or operating costs?

That said, it looks like the operating expenses you're assuming aren't too far off.The one big item I'd add into the "expense" category (though technically not an expense in accounting terms) is capital costs -- these are the long-term costs you'll face to keep the property well maintained.

THe same things can be applied to people found through EBay, virtual worker sites like eLance or rentacoder or vworker, etc.

Is this within the scope of your LLC operating agreement?

The cash flow analysis is the easy part - the operations are pretty straightforward as well - but you've got to get a good grip on the components.

"As of December 31, 2011, approximately 7,800 customers used one or more of our on demand software solutions to help manage the operations of approximately 7.3 million rental housing units."

Transfer the LLC interest, it can be covered in a well written Operating Agreement upon the event of withdrawl of a member.

.- Build in enough cushion for 'operating costs.'
