[Jeffery Shi]

why are they hard to reach out and not motivate at all ?i dont even get chance to present my offer and the deals already shows subject to bank approval.what should i do, sometimes i get back something owner has accpet the offer and now just wait for bank approval .... this happens to me almost 80% of the time i see a short sale.what should i do in future with short sale deal, what is the safest way to present my offer to avoid listing agent kill my deal?thank you
