Is it ok to tell a realtor that we’ve spoken to the owner of the main ‘comp’ they’ve used?

Place we’re interested in needs full gut Reno. Realtor told us a neighboring place needed the same. However I looked up the owner of that place and called them and they said they only did a half reno and that their place is in much better condition. Is this ok to bring back to the realtor or is this considered rude or will he think we’re lying?

It’s in NYC, a Brooklyn brownstone.
