Real estate wholesaling technology - dream stack vs essentials?

[Nick Baxter]

I was hoping to get some shared insights into what the best starter tech stack looks like for a wholesaling operation. Ideally, it would not need something like Zapier to connect tools, as that adds to the costs and can be clunky. I have a background in technology and real estate (I was a previous VC-backed technology company founder), so I am very tech-friendly, and I like to adopt solutions that streamline workflow/enable best practices. 

Some of the features I am looking for (most likely there is not 1 single vendor who has all this built-in, but more of a technology stack that integrates nicely)

Would something like propstream, carrot, and kixie be powerful enough to get rolling out the gates and still be efficient in your eyes?

In a dream world - the comprehensive solution does all this:

*task management and sequencing where you can drop a property into a sequence ie day 1 call, day 2 mailer (have it automatically mail out something like a postcard) day 3 etc etc etc

*project management outside of the outreach sequences for what's next in the process ie schedule inspection, send the contract, etc etc

*ability to have multiple users drive around and if you see a property you can tag an address and add it into a marketing sequence, and also track the streets you've hit so you're not wasting time driving by the same houses more than once 

*dialer (ability to parallel dial numerous numbers simultaneously to make cold calling more efficient - Ive used tools like orum and kixie in other industries, and when you receive a pickup, the other calls are dropped) 

*skip tracing/data provider 

*website landing page for converting online visitors to leads

*electronic signature/docusign

*secondary branded landing site on different URL for blasts for deal disposition to your buyer list

What am I missing?
