Can condo association run credit checks on new buyers?

I live in a 3 unit condo complex. One of the units went into forclosure as the owner has died. It is up for public auction and has not sold in two months. A very low bid came in and the Public Assistant may consider the bid. Do we as board members and owners have the right to do a credit check on people that bid on the unit to be sure they are qualified since we have home owner dues and a reserve?
