Raising ceiling of old concrete home.

[Patti Rosepiler]

I may be putting the cart before the horse, but I have to ask before I purchase.  There is a 1950 (small) concrete house that I stumbled upon with people willing to sell.  It has LOTS of potential in a great area and the price is right...but...I'd really want to raise the height of ceiling. Is this a huge, expensive undertaking that any of you had a ton of problems with?  I know there may be way too many  different variables to  throw out costs, but maybe a ballpark cost or some specific example of someone doing this?
