Just met with potential seller

[Nathan Habben]

I got my first answer to my ad seeking houses on craigslist. My ad explains that I am looking for people behind on payments, facing foreclosure, fixer uppers they can't afford to maintain, etc...
However these sellers did not seem real motivated at all. When I asked what price they were trying to get, they said 129K. The house is assessed by the county at 117K and I think ARV is probably right around 130 to 135K. Also it probably didn't need more than 5K in work max, mainly for outside landscaping, the inside was about perfect.
My question is, how many wholesalers out there get calls only to meet with the seller and find out they are looking for full retail price for their home? Should I do some type of prescreening on the phone to weed out people who are not real motivated and willing to sell under market value? Should I say something different in my ads? Any other ideas?
Thanks.
Nathan
