I hear you. I was in the same shoes.
To be honest, my advice is to find the right people in your area. Since it is your first investment, you can be super cautious. Do not even listen to people who say, come on you are being too conservative. Some real estate people can be very aggressive. Once you have experiences, you will learn how to deal with these people and can actually benefit from the conversations with them.
You should go to as many real estate events as possible and see and feel what kind of people are doing this business.
You will find someone who click with you. Then you should discuss your strategies or concerns deeper. There are some professionals who actually care about you and your investment. Just don buy anything until you find those people.
If you have a LLC, just buy the property with the LLC, you will be protected. A decent lawyer can just set the documents up quickly. Just do not buy it with your individual name.
For property management, there are a lot of softwares out there now. Biggerpockets has the list as well.
Just pick the right tool for you.
It is exciting! Good luck!
