Methodology and limitations
The analysis in this report rests on a sample assembled for the purpose, 20 homes in 30009 dating to 1980 or before, and its numbers come from that sample together with the published market and county sources named below (Frontier Capitals, 2026). A sample is not a census, so the 65.0 percent builder demand rate and the 25.4 percent average ratio describe the sampled homes rather than every house involved in what older homes are selling for along the GA-400 Corridor. The worked examples for what older homes are selling for along the GA-400 Corridor are simplified illustrations, including the residual range of 420,000 to 470,000 dollars on a single 1,100,000 dollar example before site preparation, and they are not valuations of any individual property. No corridor only price table exists in the source material, so corridor conclusions are drawn by applying the documented sample, the employment base facts and the residual method to corridor parcels, checked against parcel records.
Conclusion
Older homes along the GA-400 Corridor sell mainly as land with a house on it, at an average of 25.4 percent of new build prices in the sample and with builders taking 13 of every 20 sampled houses. The medians above 800,000 dollars describe finished houses, not untouched ones, and a corridor owner who starts from the land evidence prices once and prices correctly. Are you pricing your corridor house from the medians for finished homes, or from the land evidence for your own?
