How to underwrite deals without wasting a Broker’s time?

[David Murff]

Hi guys!

First time posting here and had a question. I've been studying CRE investing for a few months now. Read a lot/consumed tons of content and really excited to begin underwriting deals and making valuable connections that will build the foundation of my "team"

Which brings me to my question:

Once I’ve found a valuable deal source, how do I practice underwriting tons deals(as Brandon advocates) without wasting a broker/realtor’s time and alienating them? Considering it’s unlikely I will be confident/proficient enough to follow through any time  soon. 

Thanks!
