It all depends on BB condition. My two recent used acquisitions had badly galled spindles so needed new bottom brackets. Both bikes had been used in the dirt, one a road bike converted for cyclocross.
If disassembly and inspection reveals damaged parts then replace it. If not replace the bearings and reassemble.
