Well, it's still within the offer period. The "buyer" disappear and never confirm and carried on. Later on found out that he said he will BUY with cash for his gf and they had a fight and she said she will buy her own.. and then .. nothing...There is no need to kill people who back out of deals. This is why you pay an actual expert - the lawyer. I have no problem paying top dollar for a good lawyer. I would be happy to pay 5% to lawyer and a flat fee to a lockbox opener.
In your stupid analogy...you wont go directly to doctor, but rather pay a lot of money for an agent to find you a doctor.
Interesting story. Not so interesting when I wanted to sell my place and it was "put on hold" during that time.. Nothing a lawyer can do because they are using the inspection clause (back then ppl do have subject on their offers)
btw. I would NEVER leave my keys of my house in a lock box and let "buyer" go inside to party.
