Here are the posts I could find about Jake being home per neighbor's Twitter:
Chopstickchick - May 6 - Sleuthing Thread #1701
counthestarsxo - May 6 - #1715this guy on twitter says Jake's his neighbour!: Chris Dyer (ChrisDyer) on Twitter maybe one of you tweeters can tweet him and ask if Jake is back home, etc?!
and followed by her post #1716same user tweeted the guy who said his neighbor was on the bachelorette.. this was his response..@TugLambert He's back home now. We knew he was going on a reality show, but he couldn't say which one until they announced the contestants.
so that rules out jake from the F3, since they are still currently filming
another question regarding the bachelor neighbor aka Jake:
@dkozz Not sure. My wife thought she saw him back last week. She talked to him briefly today but didn't find out much.
