@Riquelmi De La Rosaq if this is going to be your first property, try to be as involved as possible so you get a good handle of everything that goes on. That doesn't mean answering the phone whenever a tenant calls or dropping everything to run to the property. here is what i would suggest:
1. get reliable and reasonable contractors. Plumber, Electrician, handyman, exterminator, etc.
2. give your tenants a list of those contractors for emergency purposes. let them know you cannot answer the phone because of your job but they should text you and you will respond within a few hours. let your tenants know in an emergency they can contact the contractors directly but to text you and keep you in the loop. most emergencies will be plumbing - no heat, no hot water, leak.
3. put cameras around the house and have an internet connection so you can monitor remotely. this is important to make sure you can keep an eye on the house. you dont want the garbage getting out of control. the city will give you a ticket. you also dont want your house to morph into 'that house' on the block. the one where everyone in the neighborhood is hanging out front until the early morning.
