If guys are resorting to pressure they aren't doing it right and don't really have sales technique. 

Many home owners that resort to dealing with these folks are in a bind.. and if they truly new that this buyer cannot close without reselling how many times would the seller actually sign that deal and not move on to ones that could prove it.If I was in the business of direct mail campaigns and bandit signs and based on this thread I would definitely put verbiage in my letters that I can provide proof of funds and I encourage you as a seller to ask any potential buyer for a legit proof of funds and explain what these others are doing in detail so they don't get trapped with those that can't close.There has to be some catchy phrases folks can come up with that will set them apart.

25 years ago after high school I purchased the ski rental shop that I was working in.

Using HMLs for purchase money, IMO, is a last resort.
