When I lived in Austin, Tx, I bought into a Racquet Ball/fitness center as an investment and unlimited play opportunity. It was three years old, full about 18 hours a day and looked to be a thriving business. After about a year, there was a stock holders meeting to break the bad news. The mortgage on the place was a Prime +2 interest and this was in the early 80s when Prime went to above 20 %. We were in trouble!! With in 3 months, we were looking into a $2500 "contribution" from all share holders to keep the doors open and that was not going to fly. Ended up, one of the better heeled investors assumed the mortgage, refinanced, and sold the business, leaving the rest of us with out a dime. Like Barry, use caution!!
