Removing textured walls

[Nathan Love]

Hello everyone,  

I had just purchased a house I plan to live in for a bit while I flip.  Back when looking at it, I knew the bedroom walls were textured but not that the thing is mine and I've been in it daily for the last few weeks, I'm realizing I absolutely hate the textured walls.  So my question is what is the best way to get them smooth again?  I've read a few things online talking about skim coating a few layers to even out the wall but what's everyone else take on it?   My house was built in the early fifties and I've read that sanding, outside of being messy, could be hazardous considering that at some point there may be lead paint somewhere.

 Thanks in advance
