Excellent advice Wanda Kubat-Nerdin - Wanda Can! Pushing a client into a purchase is going to lead to a disaster one way or another.

Hello Wanda,  I have had people that wanted to sleep on it and sure enough they lost the house.

Wanda,

The moment someone goes into fear mode with us, we happily leave.  That is not the best method to sell, although it works on some, and I agree with Bob "RealMan" Timm .  A

Wanda, I received an Offer on one of my vacant lots 50% of the list price... we had another offer on the table and we were $6k apart... the seller did not want to respond to the poor offer... I told him the buyer took the trouble to write a 15 page offer with proof of funds we need to reply... it took me two days to convince him... ironically the other offer went dormant... our seller's counter offer was accepted by the second buyer.... no fear just good advice from both listing and buyer's agent's side.... That is how things happen, Endre

While I understand your message, I mused at the contradiction of  the following:

"It is never okay to inject fear into the conversation, potentially forcing a quick decision."

and then...

"Let the client know that other people may be looking at the same home and if they want to 'sleep on it', it may go under contract quickly and they could miss out on the home of their dreams."

so, one might summize that...

Since that last statment actually creates a fear of loss, It is OK to "cause" some fear with facts, but not to cause false fear to manipulate. 

You are a wise woman and make your clients super happy too!
