Buying Lists in bulk. Percentage rate of a deal?

[Craig Moore]

Hi BP,

I just signed up for ListSource through my company and apparently they have bulk prices/deals. Here is one:

For $600 I could get 4,444 leads. If my math is correct, if I get ONE deal out of these 4,444, which is 0.022% then we're getting somewhere. I am about $15-$17k away from purchasing my first multi-family at 5% with no PMI. I have to get the capital and I am strongly considering this. I know this will not be easy and that I need to run the numbers, have a buyer's list ready (which I am steadily building), and get the deals done. But let's say my deals accounted for only 1% of the 4,444, that's 4 deals. I have also taken into account mailing costs, I do not suspect they will be a big issue for me.

My vision may be greatly skewed, which is why I am here to ask these questions. What are you all's thoughts on this?

P.S. a friend of mine just told me to only buy what I'm going to use, so what would you all say is a good amount to buy? Do I need 4,444? Thoughts?
