Please don’t do that. I’ve only heard two people actually say that out loud about their houses. Neither one of them live in the DC metro area. One was my mom, and this is a periodic threat, so I don’t take it that seriously. The other was some guy from the mid-west visiting, who got a little over his head.
When I was passing out fliers yesterday, I came across this scene of keys on the fence and thought of that phrase of leaving the keys and walking away. As far as I know these are some lost keys in front of a house that doesn’t look occupied.
From what little I know, walking away does not help, unless the house is actually worth more than what’s owed, because at some point the bank will come after you for the difference.
