First step - Finding a great deal or building cash buyers list?

[Sarah Castor]

I am new to wholesaling and my #1 priority is letting morals and ethics guide my business while building my reputation. So I ask... 

Is it best to first find incredible deals and trust that there will always be someone to jump on them? Or should I build up a cash buyers list first so I can increase the odds of the contract going through and not letting down the seller?

Any and all input is greatly appreciated. Also looking to network with as many people as possible - feel free to send connection requests and message me!
