Carl,
Build your knowledge and then you will have the confidence to talk to professionals and let them know what you have to offer. If you call a lender stammering that you want to buy notes at a discount and you look and sound brand new-the conversation will be over before you ever get started.
If you can approach them in a way that lets them know you can help them free up capital for more timely investments they will be more receptive. An even better approach is to get the word out about your services and let the sellers come to you! We pride ourselves on quick, competitive service from quote to funding and we try to let that fact shine through in our advertising. The results are much better when they call you then when you are calling them! Get the word out there.
