Dress Code for Property Tour

[Mark S.]

I almost feel silly for asking this question, but I have an upcoming property tour with a turnkey provider. They seem pretty casual. I'm wondering what would be considered appropriate to wear on property tour. Business attire? Jeans and a polo? Does it matter? I'm assuming since I'm their potential client they should be trying to impress ME that it doesn't matter, but I also don't want to be caught off guard and under dressed. What do you think?
