As the other two have mentioned and are quite correct, with you being prior military you should be able to get a VA home loan and if you are a first time home buyer you would still be able to get the $8000 tax credit, but that ends at the end of this year.

My suggestion would be to contact a mortgage consultant and get pre-approved before you call an agent. A good consultant can guide you the whole process. please visit my site @ http://www.madmortgagemachine.com and you can download my mortgage planning questionnaire and we can get you approved and in a home in no time

Being prior military myself I can tell you there are a few programs out there that Cater to Military personel. The biggest is your VA loan which last time I checked you could still do 0 down. Please give me a call so we can talk about your move to Franklin and Johnson Co. My office is in Greenwood so I am very familiar with the area.

Franklin is a nice area and great possibilites for home pruchase. If you are a 1st time home buyer, then you can be eligible for up to $8000 tax credit, VA loans offer "no money down" ...rates are good right now.
Would love to help you in finding that perfect home in that great neighborhood. Give me a call!
