I am automating my new website now.

They also don't have a open API which means you can't syndicate with other software's like tenant screening automation, etc as you grow.

You would have to either live close by for easy check in and out or try to find an semi automated way to do it.

This means you have a series of applications, workflows, processes (both manual and automated) and people that facilitate the operations of your business. 

They e-mailed me an automated receipt confirmation.Anything else I need to do?

You might want to use an online rent collection utility to automate the process:  automatic ACH deposits to save trips to the bank, late fee management and rent reminders.

I also automate everything, doorlocks, thermostats, cleaning, bill pay etc. good luck

I built an accounting system that was automated because I hated doing the accounting and never really figured out how to use quickbooks. 

My point is that it opens the door to other useful automation to help monitor your property.

The past rents from landlords is the most applicable indicator of credit for the type of credit being extended, you shouldn't care about credit cards or the car loan, those don't apply to you but do give a clearer picture of the big picture.Any automated system of accept or reject is pure bunk, credit scores are valid cutoff points but not without applying the type of credit history to the type of credit to be extended with rentals.
