Another year, another huge price dip on Kim Zolciak and Kroy Biermann's Georgia mansion ... and still no serious takers as of now.
The estranged reality star couple have reduced the listing for their estate once again ... coming down from $5.5 million to $4.5 million -- about a month after they brought it down $500k from $6 million.
