New landlord: Need advice on apps to manage your property and lease agreements

[Keri Win]

I will be renting 4b / 2.5b home in the suburbs of Georgia 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. I also want manage the property by myself and I do have a contractor/Handyman that is reliable. 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.

My question is where do you get your lease agreement and what app do you use to manage your property? And screen tenants?
