Would the buy side agents do this?

[Jacob Bindler]

Let say you are a buy side agent, and there is an advertising to conduct a 4 hour open house for a seller who sells on his/her own. Let's also assume that you are familiar with the area and have time on this particular day. Let's say the owner conducted preparation for the house on his own and wants you to 1) relay the info about the property to prospective buyers, 2) collect their info, and 3) pass this info to the owner. You are free to contract the buyers and represent (if they come unrepresented) them for any other properties. The owner will spend 30 min with you before the event disclosing info about the house and you would need 30 min after the event to write down the notes. 

Multiple choice question:

I will do it for 300.

I will do it for 500.

I will do it for 800.

I will not do it in principle. 

I obviously appreciate the comments too :)
