LLC or LC between father and son

[Arthur Nogueira]

My question is, what’s the best best type of legal partnership between the father and son? My father soon wants to invest in Bradenton/Sarasota, FL and he has all the cash to put it down, and he will be an inactive partner. I will be the active partner doing all the management for him. I will not put any of my cash down since I already bought my property and have a little more knowledge than he does. My other questions is what is the fair percentage of this partnership in this scenario? 
thank you
