What's Proper Etiquette When Visiting A Tenant Occupied Property?

[Josh Milewski]

I'm working a lead and the seller gives me permission to visit the property after confirming a time with the tenant. The seller told the tenant I'm an insurance agent so not to reveal the potential sale. I wasn't pleased but still went to see the property. I did not further the misinformation and when I was asked for a business card I informed the tenant I don't have one. Had he asked me to leave I would have but instead he just told me it wasn't cool, and next time he expects visitors to have a business card. Honestly I don't blame him. Is this a typical scenario? My gut feeling is next time this happens I tell the seller that I won't go along with such a situation. This was my first tenant occupied visit and my second ever property visit.

Quote from @Josh Milewski:

There's no requirement to present a business card when visiting a home on behalf of the owner. Would he demand to see a card when a plumber visits?

I wouldn't sweat it. In the future, I agree that there's no need to lie about anything. The seller needs to find a way to be honest without tipping their hand.
