Not sure where to post this, very new and inexperienced.

Hello all! Me and a few good friends decided to try the real estate investment road. One of us knew about BP and tried following its guideline. We are targeting some multifamily units. There are some in our radar with 3-4 units. Looking at low income housing. So the 3 of us are willing to go partners. Splitting everything equally. Tomorrow is our first day meeting with our agent to go look at about 5-6 properties. I've been told by some other veterans not through BP that we should be setting something up on paper or LLC or corporation to make sure we are all protected. We are all good friends so we didn't really think about it that much. Figured we would worry about that when the time came. Are we wrong in this thought process? We all share the same goals. Start off by getting our feet wet. And if things go well, expand. We want to get good cash on cash return. Cash flow properties. Intend to do some BRRRR strategy. What are our first steps? Do we need to write anything on paper for legality issues? Sorry for the long boring story I'm sure you've all heard a million times. Just looking for some advice and any tips. Anything would be very appreciated. Thanks.
