@Danielle, awesome to hear you got your house hack property. It sucks that people in your circle don't understand or can appreciate what a life-changing decision you made by buying an income producing property!
So for DIY, I used to be a construction engineer(managed contractors), my wife and I also renovated our own house hack with LVP, repainting tiles, walls etc...
I have two pieces of advice for you. One is practical and second is mental.
On the practical side, try to look for an LVP flooring that has sound blocking properties. With 4 other roommates, the more sound proofing measures you can take the better experience it will be. So flooring, insulation etc... should have sound proofing thought out. Use HomeDepot's flooring calculator to calculate how much flooring you'll need (it includes a 5% extra flooring buffer because you will mess up some cuts)
On the mental side, whether it's a big construction project or a simple LVP flooring project, you will encounter set backs, problems etc... you're going to want to give up, take a deep breath and push on. It'll get done.
We just completed a triplex renovation in Charlotte that took 1.5x longer than it should but we pushed through and we were able to double rents and improve the living quality.
Let me know if you have any specific construction or house hacking questions
