Forget Macon and central GA. It gets hot. Really hot. Texas Hot.
I live in Suwanee (Gwinnett), GA. 2nd largest population in the state behind Fulton (Atlanta and areas N and S). A 300k home has $3900 property tax. Income tax. Gwinnett is mostly transhipping companies, so many warehouse jobs, but some serious IT like NCR and Scientic Atlanta (Cisco) are here. I work IT at the airport for the airline here and that is a 42 mile one-way commute (but under an hour most of the time in the HOV lane). My wife works at Suntrust and takes a Gwinnett transit bus to 2 blocks from her building. $4 each way and a monthly pass is available.
N. Gwinnett is just inside the 'Wedge' zone. The Wedge is a weather thing where easterly and northeasterly winds draw cold are out of the mountains (which you can see the thumbnails of on clear days from the ridges). That happens about 20 days out of the year though.
I grew up in Orlando area. The humidity in GA just does not compare. 90 in Orlando is hotter than 95 in Atlanta. Few 100 degree days in either place, but central GA and north central FL (Ocala and North) get them.
If we could, we would move to Dahlonega, Young Harris, or Blairsville. In or at the edge of the mountains. Also, Wally world is nearby. Too far to commute though and no high tech there. But Dahlonega is in range of N. Fulton and Forsyth Counties and there are high tech companies there. The bridges across the Chattahoochee from Gwinnett to those areas make a 25 mile commute an hour and a half job. Cumming is up and coming (pun intended). GA 20 at GA 400 has about everything you could need. South about 15 minutes is a Fry's Electronics (there is one over here in Gwinnett too about 15 minutes from my driveway).
Where I am at, I have a lot of choices. There is a Super H (H Mart) 5 minutes away along with an Assi plaza. The competing Korean grocery stories are getting more and more cacausian as folks discover them. Example, 2 lb + lobsters were $7.99 this weekend.
GA is a little behind in some things. They are fighting over allowing Sunday liquor sales here. Was a shock on the first Sunday right out of Orlando. Planning... But, GA is ahead too. One of the more liberal concealed carrier states in the country. Folks are friendly and the racial stereotyping is totally off. In fact, reverse racism is probably a bigger issue. But I have shot the bird at some whitesheeters in Douglasville in the early 90's. They would get their asses kicked if they tried anything anywhere near downtown.
Downtown Atlanta? Nah, it won't be much cheaper than what you are leaving.
Helen GA is 45 minutes away. Just over an hour to Franklin, NC and 1.5 hours to Highlands, NC from here. All those are in the mountains. Check out Highlands and Helen some time. Highlands went for the Scotish side and is a FL refuge in the mountains (highest incorporated town east of the MS at 4100 feet in a temperate rainforest). Helen went for the German mountain town look and is a tourist kind of place, but still fun.
Homeowner insurance... about $120 with a rider.
Gas price this morning was $2.95 at Kroger.
Multiple credit unions in the area (I belong to Delta Community CU - free checking, interest paid no matter what the balance, etc.)
Kroger, Publix, WalMart, Food Lion, and the above - we just got Martin's Potato Rolls in some stores
Negatives... NE GA is multicultural. Some areas are too multicutural like eastern Gwinnett. You get some areas that are a bit like Ghettos (I mean that in the old Europe sense, not Harlem - if you don't understand the Ghettos in Europe and the seperation, don't make assumptions). Dekalb and Fulton are heavily Democrat. Forysth, Cobb, and Gwinnett are Republican. And the Liberatarians are all about. Neal Boortz lives in Fulton and I am not sure where Herman Cain lives, but I think Fulton.
The weather does get hot (103 was max last year with a heat index around 110). Cold for the area is USDA Zone 7a-7b (max low over 100 years is 0F). It was 4F in Douglasville in 1994. It has not been below 12F here in Gwinnett. ATL itself is an urban heat island. It can be 8-12 degrees warmer in the winter.
Oh, the 300k house is on a lake with a basement. I think it is 3500sqft under air.
