We need more info to accurately advise you of your best options. With that being said when you meet with your loan officer you may want to weigh your options. It might be better to refi on the exsisting home and use that cash to purchase the new property. This will allow you to be a cash buyer opposed to a FHA buyer. I am not sure about the GA market but here in Vegas it is a lot easier to get a cash offer accepted than it is to get an FHA buyer deal accepted.
Just food for thought.
My first move if I were you would be to get with a loan officer and go over your options. From there you can formulate a plan and move forward.
