If you have tenants that use the internet you could think of setting up some kind of electronic transfer like cozy.co (It is cozy.co not cozy.com). 

If the software is not simplifying your life or making you more accurate, you shouldn't use it.Software does have extremely helpful features like online payments, marketing syndication (click a button and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.

I got an Electronics Tech degree and went on to get my MIS degree.

To prevent giving them 24/7 access to our unit, we installed an electronic lock that unlocks during each tenant's "laundry window".

I'd like to get your thoughts on the best method on how to receive rent electronically.

Electronic file looks the same.File for each bank account.

The property management software I utilize recommends them, and allows sign-up during electronic lease signing. 

But Areas like Daytona Beach , Coca Beach , and further north as far as St Augustine do well too, I just saw an article  that St Augustine is the best city for Short Term Rentals .   

The county that this property is located in requires a wet signature on all recorded documents, so an electronic signature was out of the picture.

Credit card and they sign the rental agreement electronically.
