New Landlord need advice

[Keri Win]

I will be renting 4b2.5b home in the suburbs of Ga in the next few months. It's has hardwood throughout, fenced yard and screened patio, great school district etc. I will include appliance except microwave and small dogs will be ok My question is I want manage the property by myself. do have a contractor/Handyman that is reliable. My question is where do you get your lease agreement and what app do you use to manage your property? And screen tenants? The home is on a septic tank so i need to be specific with septic care. I am not in an HOA so there is no rental restrictions.
