Buy Box for Atlanta Buy and Hold Investors

[Lezly Tyler]

I typically look for properties to flip but I am talking to an off market seller that seems like a good buy and hold opportunity but I have no idea how to run the numbers for rentals. 

Here are the numbers, ARV: $345K, rents are $2,100-2500/month. Property is in great condition, so no repairs are needed, move in ready. Seller is motivated, looking for a quick sale. I was initially taught rental pricing per month/1% minus repairs minus assignment fee=MAO. Is this accurate for GA?

I will likely assign it but want to make sure it's a solid deal.  Can someone point me in the right direction or link a thread? I am new to BP -- the property is in Gwinnett county.
