So far I have an app called Acorns, it sort of helps me invest in different business.

I have started using Redfin and am finding some prospects but was wondering if other Apps or websites work better to find deeply discounted properties including auctions, REOs, etc...

If you rented to someone else, make sure you have dates, time the app came in etc.... take this very seriously. 

I had some glitches initially with licensing the app.

For me, I had voice recording apps and depending on your state law you have to notified the other person when record the conversation (I feel that when you told them "this is a recorded conversation" they will take it very serious and more than likely not to flake/ change their mind).

I've gone down the Bigger Pockets rabbit-hole that I was lucky enough to stumble across on the podcast App Store on my phone.

If you go to https://apps.irs.gov/app/picklist/list/formsPublications.html you can find these publications:  527, 544 and 550.  

It works very well for multiple rentals by setting each up as a class and assigning that class to every expense using the phone app or online.

With paper apps, you have to print them, hand them out, collect them, and re-input the info, where online apps, you just share the link and tenant applies, and you can get you screening reports directly through that process with no extra work.
