ATL Westside investor here. All my properties are in various neighborhoods in 30310, and 30314. West End is increasingly pricey, but it's a good area. It's too pricey for my particular BRRR model, but there's still deals to be made. At this point it has name recognition, so finding value there is increasingly difficult.
I spent the last 8 years on the Eastside (Candler Park, Reynoldstown) before recently moving to one of my investment properties on the westside late last year. Some of what I'm seeing in the Westside reminds me of what went down over there....albeit years behind with respect to amenities. Nevertheless, it's where young professionals who are priced out of those Eastside 'hoods are looking. I work in tech, and my peers are going west. they offer the same proximity upside as the eastside, and for this cohort of homebuyers in town living is a priority.
Lakewood is more speculative. Plenty of inventory of prerehab houses, questionable demand for finished homes, IMO.
Neighborhoods of interest are Pittsburgh, Mechanicsville, Sylvan Hills, Capital View, Capital View Manor, Westview.
Depending on your tolerance/ appetite for transitional hoods there are other options.
