I've been  watching YouTube videos, reading books/articles and taking classes on REI for a few months....

@Dustin PallsAndy McFarland has a good video about this on his YouTube channel "I love real estate stories".

If you have the money, i would do that plus add a metal z channel going opposite direction of the joists ( screwed on top of the existing plaster ) and then add another layer of drywall. the Z channel leaves a space that helps in sound transmission. the problem is the sound is transmitted through the existing floor joists too, so just the insulation will not do it because the joists are still against the ceiling. this is something similar, but in this picture they used clips in combination to hold off hat channel from the existing ceiling which will lower your ceiling about another inch. 

I read rich dad poor dad and watched a YouTube video by Jay Morrison on buying a multi family home to get wealthy.  

Take pictures and or videos of the place.
