There are apps that can monitor a person's voice from video, recorded calls, or other sources, and then it can match the way you speak. 

I already have a rockstar agent, but always looking to learn from additional voices.

We're thinking for incoming leads a google voice number, website to collect seller information, and an acquisitions email address through our google domain. 

While it’s true that most agents gauge a potential client’s seriousness by the existence or absence of a pre-approval letter, I think you can ease concerns by being honest with agents and voicing a preference to receive a lender recommendation from a trusted partner - which is what your agent should be from beginning to close.

There's a lot of toxic animosity floating around this thread and I'm trying to be the voice of reason.

I will give the REIreply skip tracing a try just to see the quality, but since I cold call as well I will probably stick to batchleads and their mobile and voice numbers.

Setup a Google Voice number so tenants can call or text the number with their requests.

Is it a journal, word document, voice notes? 

It does well as it attracts medical, academic, athletic, and entertainment.

Alongside my academic pursuits, I have been involved in various entrepreneurial ventures.
