What it costs to own a home in Alpharetta, line by line
The median Alpharetta home sold for $705,000 over the last 12 months (726 closings across 252 communities), about $240 per square foot for a typical 2,888 sq ft. Here is what that home costs a new owner each month:
| Principal & interest (6.71%, 30-yr, 20% down) | $3,643 |
| Property tax (Fulton County, 25.95 mills on 40% assessed value, after the standard homestead exemption) | |
| Estimated monthly cost to own the median home | $4,249 |
Two things out-of-state buyers get wrong in Georgia: the bill is levied on 40% of value, not the price, so compare millage across counties on that basis; and the millage differs inside city limits, so a home in the city of Alpharetta and one just outside it carry different rates.

Home insurance in Alpharetta
Georgia homeowners insurance runs well below Florida’s coastal premiums for most of the state, and it is not the budget line it is in Florida. Roof age, wind exposure and the FEMA flood zone still move a quote, so get one on the specific address before you write an offer.
HOA and CDD fees in Alpharetta
Where a community carries a CDD assessment it appears on the tax bill, not the HOA statement; ask for it on any home in a newer master-planned community. Neither is included in the monthly figure above unless the HOA line says so.

What this page does not estimate
Groceries, utilities, transportation and healthcare vary less between Georgia cities than housing does and are not modeled here; national cost-of-living indices cover them reasonably well. What those indices miss in Georgia is the 40% assessment and the city-versus-county millage split, which is why this page is built around the tax line.
