Congratulations on your decision to buy your first home together!
Atlanta traffic is becoming a serious issue for homebuyers. As an Atlanta native I can attest to the hair-pulling frustration of spending an hour in the car for a 7 mile commute.
There are areas around Vinings where you can find a home for around $250k, but they go quickly in this seller's market. Have you considered a condo? There are more condos than single family homes for sale at that price point.
If you are first time home buyers, there are several mortgage options to help you with this purchase.
If you are not currently working with an agent I would be glad to assist you with your search.
Best of luck to you both!
