I have partnered with many investors from out of state over the years. The biggest concern that i have noticed out of state investors have is their abiltity to handle an issue if/when they arise while being so far away. The easiet solution is to simply partner with another investor that is local inwhich your ideals align. when hiring the repossiblities out no one has your best interest at heart.
I would first recommend that you continue to do what you are doing. Do as much networking online, get as many recommendations as possible, then if time permites come down for a visit and get a feel for the areas.
There is oppurtunity just about everywhere here in Atlanta, it really just depends on price point. Theres new construction oppurtunity in Neighborhoods like Brookhaven, Buckhead, sandy springs, north druid hills. Additions and high end rehabs in Kirkwood, Edgewood, East Atlanta, Marietta, and North-esat Atlanta. in and out flips in Stone Mountain, Decatur, Kennasaw, ect...the list goes on.
There are definitly some questions you want to ask yourself before investing across state lines, but it is not impossible. PM me if you have any questions on how my current projects are going with my clients.
