They didn't know what they were doing and they weren't malicious. 

Note:The Administration C.T.A. are special letters of administration you must petition for when the executor in the will refuses to act or cannot act due to death, incapacity or otherwise, or if the executor resigns or his letters testamentary are revoked by the Court.

A number of exceptions to these rules exist, such as for employment by parents, newspaper delivery, and child actors.

In my area, law students and housing authorities send "actors" out to walk properties and fill out applications in order to see who violates these laws and they file hefty fines regularly.The benefit of defining your criteria is that it makes it really easy to decide who you rent to, no more comparing applicants.

Statistically an eviction process takes one to two months in Georgia but there are ways a tenant can stall and a malicious tenant may cause more damage.

I don't think there was any malicious intent here, but it seems reasonable to me that it should be up to him to honour what he said rather than me paying for his mistake.I want to resolve this ASAP because I want the house to be ready for October because otherwise I will lose October rent, and also the rental market will cool down and will be harder to find a tenant at the price I want.

Is this someone who is knowledgeable in Landlord Tenancy Act or someone knowledgeable about the legalities involved with purchasing property?

Not malicious, but honest.
