Say you hypothetically manage multiple properties for the same owner. (e.g. owner has multiple units in your letting pool.) Do you normally or always charge them the same commission? Also lease renew fee waived (no letting free for renewing lease with same tenants, free for owner.) for one property waived for all his/her properties? Or do most PMs negotiate on a property by property case by case basis? And once you waive the lease renew fee once do you forever waive it for them for life?
