Stephen even if you don't decide to target your marketing for a particular demographic, my advice is if you happen to get a motivated seller lead I would look into wherever it is. So if the seller is motivated look into it. I believe in not finding properties but finding motivated sellers.
I am new to Atlanta myself. I wholesaled a deal last month in a neighborhood I never even driven through before much less had experience in. But I had a motivated seller lead and put it under contact at the bottom range of the sold comps in that neighborhood. I contacted all the agents that represented buyers that bought in that neighborhood in the last year to see if their clients were looking for similar properties. I a full price offer the next day.
The key was that I had a motivated seller willing to sell at a low price. So this lead might be a property that isn't in as bad a shape as those $3K houses in the same neighborhood. If you don't want the lead pass it along to me. I might buy it myself. Feel free to email me or call me.
