We had a couple guests come through last year where the entire exchange was automated.  

Looking to see what CRM’s or softwares are out there outside of PropStream or Coles for finding and automating the process of finding scrubbed data for land leads. 

We have REISift as a CRM and use what's referred to as "Siftline boards" to create flows for different teams members (i.e. lead management, acquisitions, transaction coordination, etc.) and automated tasks are set up depending on where the property falls on the Siftline board. 

A couple of years ago I financed a car wash with four self service bays, two drive through automated bays, and a detailing station.

We have automated software to set up showings so we are covered there. 

I'd suggest moving off google sheets and into some more automated with less risk of input error.

You can use it to build a nice-looking store for your add-ons and it nicely integrates with most property management software, so that you can automate sending the store link to your guests
