Great question. Here at Bid13, when it comes to payments, we allow the facilities to call the shots since they’ll be the ones who will be handling them. Some facilities lower their cleaning deposit for buyers who buy multiple units, others charge for each unit, and some will just have one fee for all units altogether. Your best bet would be to call the facility you’re interested in buying multiple units from, and asking what their cleaning deposit policy is.
Good luck on your auction hunt!
