Hi Emanuel - Welcome to BP! I am also fairly new to investing, however just from you post it looks like you are interested in Buy + Holds. Buy low, fix up and rent out. My suggestion for you since you have no experience in construction is become familiar with you local contractors or rehabbers. Feel free to reach out to them for advice.
Luckily my uncle is a contractor, so that part was easy on my end. However some great advice I was given was to spend some time in places like Lowe's or Home Depot and become familiar with materials needed to rehab a home (price, types, styles etc). It may seem like tedious work, but it will pay off in the long run as the more familiar you are with what it takes to properly rehab a home, the better you will be able to analyze deals and know whether it is a good deal or not based on the estimated rehab cost.
Again, I am also new so my advice is just based off of my own personal experience.
Best of luck,
Jordan Jarvis
