dawgball,
i have refinanced on my homes, so i think this is the right time to refinance. try to keep your closing costs at a minimum. for example, i have found that washington mutual has very low closing costs, so i have used them to refinance on some homes.
i am not a big fan of owning a rental property in a different state from where you live. however, since you say that the drive is about 3-4 hours & that you will be in atlanta every other month, i think that you should try to keep the property. i wouldn't hire anybody to manage it for you because it cuts into your profit margin, & because it is a brand new condo. i have found that having a trust worthy reliable handyman & building a relationship with him is probably the most important thing you would need. this way if a tenant calls you up about something that needs repair you can just call this handyman to take care of the problem & have him bill you for the work. i would also recommend that you get a home warranty contract to cover high priced items.
i am not crazy about renting property to younger people since i have had problems with them. but if you do try renting to a married couple rather than people who want to share the rent. i have learned that the tenants who have a female living in the residence are more reliable & cleaner than renting to single males.
do a back ground check(employment, previous housing, criminal record) on whomever you rent to.there are companies who do background checks.
there are alot of other things i would recommend but am getting tired from typing(lol). if you want i would be happy to help you further, so if you want ask jack for my e-mail address.
if you are seriously thinking about this i would recommend that you don't wait to the last minute because there is some research you should do.
