You want to do what?

Maybe this is just my experience, but a number of people have approached me about buying a home.  Okay, I am a Realtor, that makes sense.  But,  there is a small number of people who have approached me, that probably could not buy a home.  To date some of my most interesting cases have been a crack head, a crazy person, and an unemployed person.  Now, I have nothing against anybody.  And I will help whoever I can.  But, some of the people that approached me, had to know there was no way they would be able to buy a home.  All of these individuals had little if any money, poor credit, and several other bad situations in their lives.  I talk to them briefly about the home buying experience and what it usually entails.  I then ask that they work with a lender to get pre-qualified.  They never come back.  They always decide after meeting with the lender that now is not the time.  As, I said, I hold nothing against any of these people, in fact some of them I consider to be friends.  They may very well get their lives together and move onto a situation where they can buy a home.  It has just created some uncomfortable situations.  I am waiting for the conversation where I tell someone that they can not use food stamps or crack as earnest money.  I was wondering if anyone else had some interesting, possibly humorous stories about people that have approached them to buy a home.
