Working with a realtor but buying from wholesaler

[John Truong]

Hello everybody. I need some advice from the BP community.

A realtor has started to work with me to find a deal.  We have already scheduled a viewing this weekend. Then, this morning I saw a wholesale post that could fit my need. Is it OK (or ethical, etc...) to pursue the wholesale deal? I can only buy one property. So if I get the wholesale deal, the realtor will have wasted his time.

Thank you in advance for your advice.
