as a single member LLC that has not elected corporate tax status (an extremely bad idea for real estate) the LLC for tax purposes is disregarded. So both the personal portion and the LLC portion would be reported on one schedule E. if you want to buy software to track income and expenses go ahead. this is a personal decision. Generally, if you hire a management company, it would be the ones collecting the rent and paying the expenses and contracting for services such as repairs and maintenance. What purpose would be served by using such a MC if you still had to arrange for various work yourself. periodically they would send you a report of what those are so you can file your taxes. using a management company that is not a corporation, would require you to issue them a 1099-MISC for the fees you pay them.
