A lot happens at ISU the other 325 days of the year. The conference center they are putting together will CHANGE the dynamic of that area alone. Can you make the 50K / year float with an AirBNB, still very doubtful. You'd need to get $160 a night for 320 days a year to break even (VERY ROUGHLY) they'd probably be able to get rented at a 30% rate for around 225-250 though. Then you'd live the high life on game days for the remaining 30K.Would the demand be that high outside of game days? Ames isn't much of a tourist destination.
