seems like sarah and her old neighbor had a few issues
“the woman was renting her house and sought out the author because the Palins had crossed her (owed her money for renovations she had done at their request and never paid her for). So she knew McGinniss was writing the book and found him and offered him the house”
The woman has yet to provide proof or to even come forward to be questioned about her “allegations.”
