Dear Gal & Marianne:
You can look around on the Internet or hire a copy writer to find just the right call to action, but something along the lines of one follow-up message that politely nudges them should be all you allow yourself.
Some people just have no concept of follow-through, so there are plenty of Buyers who will just break your heart.
Sometimes they have no reason, sometimes their expected funding falls through, sometimes they have a personal emergency that throws everything out of whack, sometimes they are just jerks that enjoy jerking Sellers around.
Ultimately, you can control what you do, but you can’t control what anyone else does.
Do unto others as you would have them do unto you, but don’t be surprised when they don’t reciprocate.
In my humble opinion,
