I manage properties for a lot of out of state owners (I'm in NW Indiana). Some buy in personal name and some buy in LLC. I've spoken with half dozen attorneys on it and get half dozen answers. As long as you have adequate insurance on house plus umbrella policy, probably doesn't really matter which route you take when you have a handful of properties. Most with LLCs have a registered agent in Indiana for the Indiana LLC.
As far as taxes, you really shouldn't pay much especially if the property is leveraged. The expenses (taxes, interest, insurance, repairs, management fees) plus depreciation usually get you pretty close to a net $0 on a single family home. If it's owned cash, you'll likely see a gain but we're not talking about a life changing amount per rental. The appreciation and other benefits offset the minimal amount of tax you'll pay on the gains. But chat with your CPA and give him some fake numbers to play with to see what it'd do to your situation.
