In brief i found it was plenty helpful for me to get started on my RAL journey and previously i posted about my experience in starting my own house in Scottsdale (a 10 bed/10 bath) facility.

Do I have to turn on the utilities once I buy the home?

Establish Track Record (Small Deals & Personal Equity): Most GP's start by acquiring/developing smaller properties where they alone can fund the equity side of the capital stack (IE - no raise). 

You could also look to raise capital from family or friends as a good start.

Most of my tenants aren’t tech savvy and would find having to utilize an online platform for maintenance requests to be burdensome.

First I would call the local utilities and contractors who deal with this stuff to see if your assumption is true.For electricity maybe some sort of generator?

You can install a digital sub metering system without even cutting any pipes or getting the utilities involved.

I want to understand my possible options to get started with real estate. 1) Should I buy my first house first?

I just wanted to know if it’s necessary to start a LLC before my first deal and have a good business structure ?

It does not matter where you start as long as you develop your Core 4.
