Using existing cable for ceiling fan
I have a light fixture that currently has one 12-2 cable from the switch to the fixture. I would like to put in a ceiling fan.
Can two 12-2 cables be used instead of one 12-3 cable for controlling a ceiling fan and light separately(one switch for the light, one for the fan)? Can I just tie the neutrals and grounds together on each end? Thanks.

Just as easy to run a new three conductor cable as a new two conductor cable but either way would be code compliant. The existing cable can be abandoned by cutting it as short as possible on both ends and shoving it out of bot the ceiling box and switch box. No need to remove the cable other then that.
The ceiling box you have is probably not fan rated so it will probably need to be changes out also. If your not sure post a picture but if it use 8-32 screws to mount fixtures it is almost certainly not fan rated.

Yes, you can use two 12/2 cables. Tie the grounds and neutrals together at the switch, but you must keep the neutrals separate at the fan/light. So the fan hot/neutral would be connected to one cable while the light hot/neutral is connected to the other wire. All grounds are tied together at the switch and fan.
You likely will have to replace the box too. You need to use a fan-rated box that's securely attached to the joists. Most fan boxes can be installed without removing any drywall though.
They also have remote controlled fans these days, you just provide power to the fan and the remote control handles the fan, light, speed, etc. Just as another option.
