Real Estate Wholesaling Cold calling

[Samuel Akisanmi]

Hey guys, im a newbie, just started wholesaling 3 months ago, my capital is low cause im only 18 but I've been spending about $120 getting 250 calls every week, but so far I've had no success. I've had a couple of numbers respond, (about 5) but they always end with the seller going dark on me not replying to anything to send them. Most of them say "I need to talk to my wife" and then they ghost me.

My usual cold calling script, I say "Hi my name is sam and I'm just wondering if I could buy one of your properties" 

Could you guys please help me out and point me in the right direction?
