Best way to screen tenants, write lease, collect payment

[Alex Kouvatsos]

Hey everyone, I'm new to the RE world and am looking at a few properties in my area after a lot of research. What's the best way to:

1. Screen potential tenants

2. Writing up a lease

3. Collect payment. 

Totally newbie question, done a lot of research on actually investing but wanted to get some insight on this process. (I've heard of services online that deduct from the tenant's bank account for example.)
