I had a mentor to help me at times before I felt comfortable- If you lack this I would suggest contacting a realtor and giving them your business if they can get a higher rent.

But, you could even tell them that emergencies (think water damage or structural damage) could be authorized without your consent.However, also consider if there's someone else State-side you could designate with a limited or durable Power of Attorney (which you need to do anyway since you're deploying).

Of course it's all about comfort level and what kind of rentals you buy but you can certainly play it safe and do waaaay less than 100% cash.

I like padmapper.com and of course craigslist.I feel like that'd be a good starting plan to get comfortable with things.

On weekends, knock on doors - find a partner if you aren't comfortable going alone, lenders can be great pals.

Are you speaking about transferring the title of the property or transferring the loan into the LLC designated name? 

These issues are bound to happen.I would suggest learning more about real estate so that you are more comfortable with becoming a landlord.

@Brandon McMullin - what are you comfortable with and what are your goals?

I'm getting more comfortable with living there,  its such a huge difference from living in the NYC. 

A income fund will comfortably generate 8-12% returns annually where as paying down a mortgage is only going to save you 4% (mortgage interest rate).
