I have been asked by a few realtors if I would consider offering the service to upload the photos for them as an add on.
I just can't imagine I would recoup the cost of an associate membership to do this, not to mention my time. Do any of you offer this service?
Yes, I agree, I would stay away from uploading photos to your client's listings. Besides not being able to recover your costs, my concern would be more related to having photographers accessing their clients MLS accounts. In the office I worked in, the office support staff had special accounts that allowed them to upload photos to any agent account in their office. This is more appropriate than having photographers do it. Brokerages should carefully control access to MLS accounts!
A far more useful reason for a photographer to get an associate MLS membership would be to be able to get an MLS key box key and to shoot listings without the listing agent being present to give the photographer access to the property. This can be a huge advantage. It saves the agent a lot of time.
