The median price for 30328 in the 31 days of 1/09 is not easy to determine - there were only two sales that month - a 4/4/1 on High Top for $477800 and a 4/3 in Mt. Vernon Woods for $206500. Not really enough evidence to find a median. There were 8 total sales in the zip code that month.
...many called January 2009 "the bottom."
The only sale of a 4 bedroom inside 30328 in the 31 days of 1/10 was a $200000 sale of a 4/2/1 in Mountaire. There were only 8 total sales that month in 30328 too.
If I were you, I would find none of this very helpful.
With a name like Intellmkt, I would think that you just might have a hyper-local resource in the zip. I suggest that you contact someone like Jennifer Barnes at KW for some real insight into 30328.
