In the last several years, this addition to a sale agreement seemed to be that magical ingredient that somehow swayed sellers to come to the light and agree, emotionally based, on that buyer who hooked them with the love letter of introduction. That was often in the "city". Portland Oregon's market (90 minutes from my rural market at Fishhawk Lake) was so cra-cra that they would pull out all of the stops to make THEIR buyer the one. Out where I am, in the middle of nowhere, with about 75-80% of my niche market being second homes, this wasn't common. Or even discussed.
