Lazy buyer's agent. You're right, that is unusual.
Buyer is going to read something in a report that the buyer's agent has no context on because they weren't there. As a result, an ant hill will be made into a mountain. And you as the listing agent are going to get some ridiculous repair request that the buyer's agent didn't/can't filter or moderate, because they weren't there to see the thing in person with her own eyes. Your seller will of course refuse this ridiculous request. But, because the other agent didn't see the thing in person, they will not have a leg to stand on when they go back to the buyer with your seller's refusal, jamming up the negotiation process.
Good luck with your listing... Hopefully I'm wrong!
One of the top listing agents in my area told me she refuses to accept offers from Redfin because they use $35/hr zero commission "associate agents" to host inspections/appraisals, etc, rather than the actual deal-writing agent, causing the above to be the norm w/ Redfin rather than the exception.
