Some apps have added features like integrated bank feeds, automated rent collection, and smart scan, which allows you to digitize receipts (by taking a photo of them).

They dig it!

I am an investor (in addition to my full time job in digital marketing) and mainly wanted to get my license for my own deals that I'll be doing.

We would like to digitize this process and I was wondering if anyone has any recommendations for software?

Way back before advances in digital banking, I had these tenants provide me money orders or bank checks, place them in rent payment boxes I placed in the foyer of each property.

While this could have some midterm appeal using the insurance placement strategy, it's probably not going to appeal to traveling medical professionals and digital nomads.

Almost every single payment these days is made digitally or with credit cards.

As David said, for a SFR, that effort is overkill and all too often, those starting out get bogged down with spreadsheets, tablet applications, digital 3D renderings and in doing so, loose focus on what the point is - get in at the right price, get it done for the right price in the right time and cash in on the way out. 

But if you want to create specific codes with certain digits (instead of random), you either need to be close enough to the lock to use bluetooth or you need to have a gateway.
