Some dancers have full-time job or are students, these people might be more stable in social and economic status. However there are way more worse people than good people in this industry. No matter if they are bringing in in-call sevice to your place or not. It's simply danger to rent to them due to their nystery social relationship and contacts comes with their job.
If you want alternative payment for your rent in some occasion that's a different story :-) I am just joking.
