I live in an older apartment building. I have my 120 placed over top of 2 floor joists, one end against the load bearing wall, and at the other end I have a jack post spanning the 2 joists. You should be fine as long as you put jack posts in the basement, (before you fill it). Sagging floors can cause cracked walls, especially if its plaster like my walls.
Jack posts can be bought for about 40$ at a hardware store, but check craigslist for used ones.
