Plus I added a bedroom by using half of my garage.

Usually I manage the houses myself, but being that I'm going to be 1000 miles away, its not quite practical.Thanks,Erick

I see your in Mesa, I'm in Ahwatukee, I'm sure we can find a spot half way between us.

I figure that if I spend $15k said and done all expenses included to get a mobile duplex on to-code concrete piers, I should be able to recoup that in a year and a half.

Should I use a real estate agent or a marketing campaign to find the other half of my 1031 exchange?

For a rental, you can cut it in half.  

Your question is a very important one, as finding great deals is way more than half the battle for successful real estate investment, IMO.At their core, most strategies seem to be to focus your acquisition targets and process to either eliminate as much competition as possible while still acquiring quality properties and/or by developing and leveraging a competitive advantage.

It is half occupied and I could fill it up in a week without any repairs.Feedback appreciated

For me, I wanted my passive rental income to be about half of what I needed per month (and that was after all my expenses and reserves were accounted for), and I wanted 3 months of my expenses covered in the bank in some form. 

All companies agree there needs to be piers all around one half of the house which is low.
