yellow cards campaign result- is it effective?

[Gamal Darwish]

30 days ago , I order 1200 yellow cards from yellow card.com , I obtained the list from listsource.com , here is the result I got 70 returned cards due to inaccurate addresses so far , about 10 total calls, I meet only 1 seller in foreclosure, she was behind 12 month in payments, her house need 40 K for updating, ARV 170. so there is not enough spread , not only that the seller want 80 K .

listsource.com provided me with :

1) absentee owners with 100% equity ( 500 cards) : these owners are not motivated as much as I thought, many of them want 100% market value, not wiling to consider seller finance of any type, or telling you the least price that they can accept. they want me to give them offer since I approached them to buy their property.

2) pre foreclosed list with 40-50% equity (out of 700 cards) : only 3 responds back.

the result is worthless while it cost me about $700 for the total of 1200 card
