basement finishing

We are in the process of buying a new home and the house we are attempting to buy has a basement that has been framed in but not finished. The home owners even went as far as putting in the insulation. However, my realtor pointed out that rather than framing things in with a floating wall they installed things the non-Colorado way with everything attaching flush to the floor. So if we were to get the basement up to code so that we could finish it one day, we would need to make all the walls that are already up floating walls. My thought would be just to cut all the 2x4 vertical studs off about 4 inches up from the floor, attach a stud across the bottom, and proceed from there with the steel spikes and such. However, I also question if we would be able to maintain the structural integrity of everything going this route, and how easy it would be to attach the stud to the bottoms of each vertical stud given we would only have 4" or less to work with. Does anyone have any thoughts/recommendations? Do you think we would need to tear everything out and start over? If we go over to the house again sometime soon I will try to get some pictures. There is part of me that hopes the inspection catches it and requires the current owners to pay someone to make it right but that might be wishful thinking.
